Ag Sciences interns blogging

View from John Owen’s internship across Europe. As he described the day in northern Italy, “Majestic mountains and castles towered over the landscapes. Vineyards covered the entire valley floor.” Not a bad way to spend your summer, Jay!

Each year we have 25-30 students interning around the world. Some choose to use this blog (students categorized by year) and others have a separate blog. This summer see our group of Cornell Cooperative Extension bloggers; junior Rain Hennessey interning in Western NY working with youth education and GIS, sophomore Kaitlyn Kelder working on agricultural pests in the Hudson Valley, sophomore Kelly Albanir working in Delaware County with field crops and nutrient management, and senior Richard Smith also working in the Hudson Valley with the Master Watershed Steward program. Joining Brooke Parsons and Daniel Boucher in their viticulture and enology internships, senior John Owens is traveling Europe learning and interning in Switzerland.

Farmers Markets Everywhere

Since I’ve been in Virginia I’ve worked at 4 farmers markets in the area; Harrisonburg, Rockbridge, Staunton and Lexington. I went to Harrisonburg and Stuanton with Mountain View Farm Products and Lexington and Rockbridge with Cherry Ridge Farm. Harrisonburg Farmers Market is one of the largest in the Shenendoah Valley area. It’s set up in similar in Ithaca’s since it is also located in a large wooden pavilion. It is open Tuesdays and Saturdays and is a highly competitive market for vendors. The market managers and staff look for unique products and crafts like handmade dog collars, glass blowing and wood carvings. Along with these specialty items, they also have vendors that carry traditional vegetables and produce. Harrisonburg only accepts vendors that sell products that were made or grown directly from their farm. This helps ensure that customers are getting and supporting local products.

Harrisonburg also allows credit transactions because their volunteer booth uses a system where they can swipe credit and debit cards and exchange it for wooden tokens that can then be used as money with the vendors. This system also takes food stamps and then the market matches the amount. For an example, if someone had a ten dollar food stamp, the market would give them another ten and they would have twenty to spend. The market also has a cooking demonstration that offers benefits for low-income individuals if they come and watch it. This demonstration also uses ingredients from the market. I believe that this system is extremely beneficial to people in the community and helps promote healthy eating.

Marketing is very important to farmers markets. Many markets in the area had Facebook pages and used other social media sites to help promote the market, vendors and help increase awareness of the local food movement.

The Rockbridge, Stuanton and Lexington markets are much smaller and are not located in a pavilion or other infrastructure. For these markets the vendors bring tents and set them up in a designated parking lot. They also require all vendors products to be brought and produced directly on their farms.

Some of the markets are very competitive. There is a huge waiting list for the Harrisonburg market and a lot of politics involved. The Lexington market is also pretty picky about the vendors they let in. These systems showed me how important it is to have unique products, plants, produce and crafts. Value added products seemed to sell well because there was an abundance of beautiful produce. Its hard for vendors to compete and most of the markets had set prices for more mainstream produce.

Marketing for the volunteers and organizers of the farmers markets is vital. Marketing for vendors is also extremely important. Set up, product displays and speaking with customers all play pivotal roles in this process. Being friendly, inviting and informative is also important when dealing with customers and I gained experience and confidence in all of these areas. I was also able to meet a lot of wonderfully interesting customers and other vendors.

Planting Hydroponic Lettuce

Hydroponic lettuce at four weeks and one week.

Greetings from western Pennsylvania! I have been learning hydroponics throughout my summer internship at Yarnick’s Farm. I have found great interest and opportunity learning about the entire system from seedling to sale.

 

Green and Red Bibb lettuce, kale and Red Oakleaf lettuce are all grown hydroponically in the greenhouses. Plants grown without soil are considered to be hydroponically grown. Confusing as it may be, hydroponics encompasses plants grown in foam, gel, perlite, or water. On Yarnick’s farm, the lettuce is grown hydroponically in foam and water.

 

The process begins with a foam tray. One lettuce seed is placed in each hole in the foam tray. This tray is then watered as any normal sprouting seedling would be. The sprouting seeds must be kept in moist conditions. The trays must constantly be monitored; a dried tray equals a loss of seeds, foam, money and most importantly, time.

 

After the first two true leaves erupt from the young seedling, each foam square containing this delicate seedling can be planted. Due to timing issues, the plants may have two true leaves or five beautifully developed, upright leaves. The foam squares are carefully separated. If the seedlings are damaged, have abnormal growth (sideways) or look inferior (yellow leaves, small, signs of oxidation), they are discarded or left to grow a little longer.

Planting Red Bibb lettuce in the hydroponic channels.

 

Each foam square will be planted into one channel. The foam is slightly smaller than the square hole and must be level. If the foam is slightly tilted, the plant will grow in a tilted manner. This disrupts the uniformity that the greenhouse gives a grower. It also interferes with the surrounding plant’s growth habits, causing greater uniformity problems. To many consumers, an abnormal looking plant is unappetizing, even if its nutritional value is not affected.

 

A fertilizer is mixed into the water that is pumped throughout the system. A filter will capture roots, dirt, bugs or unwanted items that can plug the entire system. The lettuce must routinely checked to make sure it’s nutritional and environmental needs are met. If the system was to get plugged or turned off for any reason, the plants will immediately begin wilting, dying and crop loss will become inevitable.

 

Bottling and Tasting Room

Testing the pH of a wine. Typically, though, only SO2 is tested right before bottling (the wine’s sugar and acidity has been adjusted previously).

At the beginning my summer, I began working in the vineyards and began to familiarize myself in the winery. A couple of weeks ago I mentioned some of my bottling experiences, and since then, I continued to bottle a couple days a week. However, for the last two weeks, my time is mostly divided into “bottling” and “tasting room” days.

A flow meter. Used to measure the speed and total volume of wine being pumped through the attachment.

On bottling days, we pump the desired wines from their tank to the tank inside the “Morton” (the warehouse building where the bottling set up is kept) to a tank. The wine is then filtered through 25 large filter pads and pumped to the bottling machine.

When the wine is bottled, it is transferred from the 1,000 gallon tank behind me through the filter in front of me, and pumped into the bottling machine.

The rest of the week (and weekends) have been devoted to tasting room work. Thus far it seems that this consists of stocking wines and pouring wine for customers. Having received a set of the vintner’s notes on each of the wines, and having to convey that knowledge to customers has been a great way to get the know the products offered. It also helps that I can then ask Aaron (the wine maker) about them in more detail on bottling days. However, many of the customers would prefer to talk about their days, other wineries, or just anything else.   The the days are less physically taxing than in the vineyards, with a much lower likelihood of sunburn. Instead, a long day of making small talk with strangers can be either relaxing and interesting and/ or mentally exhausting if there is a flood of customers. It seems that the two extremes of monotonous physical vineyard work and being accommodating and interested by everyone that walks into the tasting room are not exactly what I am looking for a career in. If I could keep switching from one to another as I have been able to do while being an intern, that would be ideal. However, there are more options, and I find myself looking toward this coming Fall semester to learn more about wine marketing from a new 2 credit class that is being offered.

Sample Processing

In my previous post, I mentioned processing the samples taken in the field for my personal project on zone tillage depth. I first put them through a grinder, as the soil needs to be fine in order to analyze it in the lab. Once this is done, it is brought to the lab where 10 grams of each sample is weighed out and separated.
Next, active carbon is added to ensure more accurate nutrient analysis. For this project, we are only testing for soil nitrate levels. Morgan’s solution is then added to each of the soil vials and thoroughly mixed together.

The samples then are put through a very fine filter in order to separate the solution from the solids in the soil. Small amounts of each of the sample solutions are then taken in order to be analyzed by the computer. This process is quite time consuming, however many samples are able to be done at once. At a glance, it does not seem like there is a significant difference between the numbers. Now the next step is to organize these results and see if any conclusions can be made.

Working in the Vineyards

Cincaut vine

The past couple of weeks have been very exciting, filled with lots of traveling, interesting work at Casa Sicilia, and fun adventures in Novelda! Recently I have been working a lot in the vineyards.  I work with two other permanent vineyard workers.  This week we completed an entire parcel forming the baby vines.  It is an important job because the vine will keep this shape for the rest of its life.  The vines have been grafted onto American rootstock, which are resistant to the pest, Phylloxera.  The graft is a couple inches under the ground so the entire top part is the variety that they want.

Cutting away excess shoots

This is a red variety is called Cinsaut that the wine maker is going to experiment with in the Celcilia Rosé.  It is a very heat resistant variety and is used in blends to add spice and aromatics.  It would be good for a rosé because it has very little tannins but is very aromatic. In order to form the vines we find the straightest shoot and cut away the others.  If there is any American vines that are growing from the bottom graft, we pull them out by their roots so they don’t grow back.  Then we move the stake as close to the shoot as possible to make sure it will grow straight.  We tie the shoot to the stake on the right hand side so that later when it is taller we can bend it over to form the cordon.

All done! vine tied to stake

 

 

 

 

 

 

 

 

 

 

 

 

By the end of eight hours my legs hurt like crazy because we are squatting and standing and squatting and standing a million times. After a week of this I will have legs of steel! But it always feels good to look back on a completed row and see how perfect all of the  straight little vines are! Outside of work I have gotten to tour a lot of Spain. During the weekend I visited some friends in Madrid and toured the city. It is HUGE but very cool. OH AND I have been converted into a coffee drinker!  Most afternoons I go to a park in Novelda with a group of  Spanish friends from Novelda that have adopted me this summer.  They can’t really get through the day without their afternoon coffee. Anyways that is a little about what I have been up to.  Adiós for now!

Rain, rain go away!

During the early months of my internship, the region I was in experienced some wacky and unusually wet weather. In late May and June we experienced heavy rain on a daily and weekly basis. Because of this, multiple farms and the community experienced different effects from this. There was major flooding of fields, roads and homes. At times sections of the bottom field at Cherry Ridge Farm were completely submerged in water for days. The rain and flooding created some negatives and positives for the farming community in the area. Some examples of these were that the outside tomato crops get diseases and died and potatoes were rotting in the ground.

Another crop that was greatly effected were the hops at Whipple Creek Farm. In June we realized that some of our plants had downy mildew. Downy mildew produces stunted shoots and yellowed spotting of the leaves. We soon realized after doing a more advanced sweep of the field that the majority of the plants were infected.

Our next mode of action was to completely weed the beds of all the hops and strip all the leaves and new growth about 2 feet up the plant. This was extremely time consuming and labor intensive and took us about a week and a half. In conjunction to this we began using a fungicide called Zerotol to help control this problem. We used a mixture of 2 oz. Zerotol, and a gallon of water. We then used hand sprayers and individually sprayed every plant. This was another job that took a lot of time to complete and was also a health hazard if the person spraying wasn’t wearing the proper protective gear. We continued to spray about twice a week for about the next month and a half. The mildew eventually subsided and seemed to have mostly gotten under control.

The weather continued to be rainy throughout the summer and never seemed to be normal. This spring I took a class about Climate Change and Food Systems and learned about flooding and the problems it might cause our farmers. I feel like I definitely experienced the challenges that a rainy season brings and it helped prepare me for the some of the problems I might encounter later down the road with other jobs I have.

Casey gives a thumbs up

It has been about a month and a half since I started my internship in Professor Matt Ryan’s cropping systems research program and so far it has been a very fulfilling experience.  On my first day, I met my new colleagues: graduate students Jeff Liebert and Ann Bybee-Finley (both pursuing a master’s degree in agronomy here at Cornell University), and Casey McManus, who started working as a volunteer in the lab but eventually acquired a full-time position in the program.  Right away I knew I was going to have a good time working in the lab because my colleagues were some of the most erudite I have met at Cornell.

Funneling the ground-up sample into Whirl-Paks

In the first two weeks, most of our work consisted of cleaning and stocking our brand new lab room, and then visiting the Musgrave research farm to gather field samples for one project looking at the effects of hairy vetch seeding rate and timing on nutrient quality and amount of biomass.  One of the first things I learned in the lab was proper field sampling procedures.  We used quadrats to square out a representative sample in each plot, and then used both pruners and electric clippers to collect everything within the quadrats.  We collected each sample in cloth bags and dried in ovens to prepare them for grinding.  After about four or five days, the samples were dry enough to be weighed and ground for nutrient analysis.  We spent long hours at the plant grinder processing every single sample. I actually discovered some great music while grinding it out in the grinding room (Thanks Pandora!).

Ann finalizing spreadsheet for seeds per acre

After the first couple weeks of collecting and processing samples from the field, I helped Ann with her forage intercropping project by counting out the seeds of pearl millet, sudangrass, sun hemp, and cowpea for planting in 128 plots with different seed to seed ratios.  She taught me how to use the seed counter, which used a laser to drop a certain amount of seeds into coin envelopes for storage.  We also inoculated the sun hemp and cowpea seeds about three days before planting.

On the few days during which we had not had much of our own lab work to do, we helped Laurie Drinkwater’s team out at the Musgrave research farm.  They were doing some work with clover plants, using 15N as a tracer to determine nitrogen levels in the soil after the plants have been clipped from their original plots and  turned in new plots.  After a half day of clipping clover and shoveling soil, I ended up helping graduate student Zhen Han with her soil emissions project by setting up ground collars (made from orange Home Depot buckets) in each turned clover plot, which were later to be covered with plastic chambers (made from the same buckets, I believe) to collect the emissions.  I got a nice sunburn that day — I forgot to get sunblock (I was accustomed to Ithaca’s cloudy weather in the normal school year).  Lesson learned.

Caring for Basil

Thai basil at a perfect harvesting state- green, disease or pest free leaves, flowerless.

Hello from Indiana, Pennsylvania! I am interning at Yarnick’s vegetable farm until August. I’ve been busy planting hydroponic lettuce, harvesting vegetables, processing vegetables, working with herbs, and caring for flowers. Over the course of summer, I will be learning about large scale vegetable production literally from seed to sale.

 

Basil is an herb used primarily for culinary purposes. The leaves are harvested and used in a variety of dishes including salads and sauces. Thai, purple, lemon and common basil are grown in the greenhouses at Yarnick’s. These annual plants require at least six hours of sun a day, moist soil, and will not tolerate frost conditions. Basil will, however, tolerate high heat conditions that will wilt other plants.

All the basil plants begin as seeds planted in potting soil. Once the true leaves emerge, they are planted in the corners of the herb towers. In other words, four plants will be in each level of the tower.  The herbs are set on a watering timer which keeps the soil moist. Fertilizer is mixed with the water so that all nutrient requirements are met.  Essentially, basil is kept under optimal growing conditions in the herb house.

Pinching back Thai Basil’s purple flowers

Basil needs pinched back after six weeks to promote a bushy growth as opposed to tall or elongated growth. Auxin is a plant hormone located in apical tips responsible for tallness (apical bud growth) while cytokinin is a plant hormone located in the roots responsible for bushy growth (axillary bud growth). When the tips of a plant are removed, auxin is removed. This lowers the concentration of auxin in the plant and therefore raises the cytokinin concentration in the plant. This spurs axillary bud growth or bushiness.

Basil will be harvested after six sets of leaves adorn the stem.  The plant may be dug up and sold as fresh basil or it may be cut to half an inch above the soil level. The fresh basil, which will have most of its roots, will be placed in a clear bag filled with water.  This allows the basil to survive longer than rootless (cut) basil. The cut basil can grow back, which eliminates the need to replant.

One of the greatest ways to keep basil’s lifespan longer is pinching back the flowers. Normally, plants grow to a mature size and then reproduce when environmental conditions are favorable. When harvesting an herb specifically for the leaves, not the seeds or fruits, reproduction is a negative aspect. Hence, the basil flowers are pinched back and removed to keep the plant from using energy on reproduction. For example, Thai basil will create purple foliage and flowers that will be removed when spotted. This extends the life of the plant and keeps it in a continual harvest state.

Mountain View Farm Products: Cheese, cheese and ice cream

Throughout my internship I was able to work with multiple different farmers and their businesses. One that I spent a lot of time with was Mountain View Farm, a 250 acre dairy farm that also made farm fresh dairy products. In the summer Mountain View Farm milks about 180 of their 200 cows twice a day, during the winter this number decreases. Their cows are grazed and fed a non-GMO grain. The owners, Fred and Christy Huger and their three wonderful kids live and work on the farm. Fred handles and manages the dairy and cows while Christie makes the dairy products. Their business has a great story and has evolved and grown in a short amount of time. Christie originally started making cheese out of their kitchen, then upgraded to a trailer. As demand continued to grow she quit her full time job as an art teacher and decided to make cheeses full time and eventually built a cheese making and cheese aging facility on the farm. They sell and make a variety of different products like hard and soft cheeses, milk, butter and ice cream. All the their hard cheeses are made from unpasteurized milk and because of certain laws have to age it for 60 days. Their soft cheeses and spreads all use pasteurized milk. Mountain View Farm makes a variety of different cheese products like: jumpin’ jack chive, cheddar, feta, gouda, swiss, pimento cheese, mozzarella, fromage blanc and colby. Many of these cheeses have different flavoring added, like herbs or habanero apricot jelly.

During some rainy days I helped make cheese at Mountain View Farms. One day I took the cheese wheels out of the press and put them in a mixture of salt water. I also took cheese from their aging room and dusted off the mold, then painted wax on the bottom and sides. I helped churn, make and package fresh butter, and this butter was amazingly delicious. Everything sold was hand packaged. When we made salted butter I sprinkled in the sea salt then hand stirred it in.

 

One very interesting business and marketing strategy that Mountain View Farm used was with their product, Meow Milk. This milk was commercially sold as a pet food product because it was hand bottled, lightly pasteurized and non-homogenized. For these reasons it could not be legally sold for humans. Despite this, it was a top selling item.

I also helped make mozzarella which was a delicious process! I stirred the cheese curds, then stacked them to be put in plastic bags and refrigorate overnight. The next day you have to heat up two pots of water, then put the curds in the first pot for a couple minutes, then switch it to the next. Then you take the curds and stretch the mozzarella and form a baseball sized ball. The trickiest part of all this is not eating all the warm and gooey cheese.

I also was able to go to two local farmers markets with Mountain View and help sell their products. I also grew very close with this amazing family and their kids even took me out shooting and hunting. The Huger family taught me about cheese making, running a profitable business, marketing products and working extremely hard and efficiently. I had a truly wonderful time with them and cant wait to go back and eat more cheese!
