I had the pleasure of following Farmer John around the barnyard this morning to get some knowledge of our soil fertility tactics here at GTF. We first discussed cover crops. John says that cover crops work well for farms that have long rotations, or space that they do not need to plant anything into for up to 6 months. In the traditional cover cropping system you let the crop go for awhile, sometimes until as much as 6 feet high. Then, you would disc it down and let the green material break down for another 6-8 weeks before it’s ready to plant in.
We have a bit more of an intensive rotational system because most of the land we farm is planted almost all year round without much of a break, since we over winter quite a bit of crops. We do however have some parcels of ground clear of food crops in the winter that we will utilize cover crops in. When we use cover crops we usually plant field peas, vetch, and rye. Our cover crop system is a little bit more modified than other farms. We will let them grow until just before we need to use the parcel to plant in, and then we use a forage chopper to truck away the greenery as one of our compost feed stocks. We can then plow, disc, and prepare the land to be ready to plant in the next day. This saves us the 6-8 weeks of waiting for the plants to break down in the field. In our case the cover still serves the purpose of holding the soil from eroding in the winter rains as well as keeping the micro-organisms healthy and happily eating away.
As I followed John around to assess a manure spreader that went out of commission last night, he explained that we will use this tactic especially in fields where we will be planting later summer crops such as melons. There is a point in the fall, towards the end of October, that it gets too late to plant a cover crop. If we don’t plant early enough the cover crop will not have a developed root system, and we will end up with an insignificant crop that will not hold the soil or build it. If we don’t plant anything into an empty field, winter weeds can serve the same purpose; or in fact chickweed, which grows in plenty around here, makes a great winter cover.
As John got out from under the manure spreader, diagnosed the problem, and then made a phone call to our loyal mechanic, he added that we tend to rely more on compost than cover cropping. Our compost is a stable addition to the soil. We do two main types of compost: your basic compost and composted chicken manure. The chicken manure compost along with a fish fertilizer that we run through our irrigation are our two main fertilization tactics for crops that need more nitrogen to thrive. We also apply gypsum to all of our fields since our soil is low in calcium. The good thing about gypsum is it doesn’t change the pH of the soil either, which is another important factor. As I wrapped up brain-picking with John this morning, socket wrench still in hand, I was just amazed with the amount of interesting information I had learned. Maybe I should do this more often!

On Purple Viking Potatoes
These purple Viking potatoes were freshly harvested this week. The skins are sensitive and have not hardened yet. These potatoes are a bit more starchy, but do well baked or boiled. I would mash them up with some butter and salt. If you wanted to try something different you could boil them whole, then chop and add some balsamic vinegar, mustard and salt while still warm. They are also quite tasty roasted with the usual rosemary, salt and olive oil.
1/2 cup bulgar
1 bunch parsley, chopped finely
1 bunch baby onions, chopped, greens and all
2 tomatoes, chopped
1/2 cup fresh mint leaves, julienned (optional)
1/4 cup or more lemon juice
1/4 cup or more extra virgin olive oil
2 cloves chopped garlic
Salt and pepper to taste
Optional: chick peas, cucumbers, a pepper
Boil 3/4 cups water, add to bulgar and cover. Let sit for 15-20 minutes, or until bulgar is tender. Add lemon juice, olive oil, garlic, salt and pepper. Place in
refrigerator. Add the rest of the ingredients about 30 minutes before serving. Serve cold.
Raw Beet Salad
1 bunch beets, greens chopped off and beets grated
3 Tablespoons extra virgin olive oil
3 Tablespoons apple cider vinegar
Pinch of salt
2 Tablespoons honey, maple syrup or sugar
Combine all ingredients in a mixing bowl and season to taste. This is a very simple salad. It goes great on any green salad.
Variations: add grated carrots or chopped parsley to switch it up.
