Jade’s fields typically have too much moisture in the spring and few have drainage tiles. Cover crops soak up the moisture while capturing the sunlight, and if legumes are planted, they also provide nitrogen credits. Jade is more interested in utilizing diverse crop rotations and planting cover crops than having to install tiling.
“We work with the natural systems and ecosystems and it’s hard to put dollars and cents on that when there is a benefit, like when we’re breaking pest cycles.”
Equipment: Planting, Underseeding and Fertilizing Crops
Jade uses a 50-foot Bourgault single disc planter that has hydraulic openers and 7.5 inch spacing with a mid-row bander fertilizer application system. With this system he applies anhydrous ammonia and dry fertilizer. His planter holds 450 bushels across four tanks, which works well for planting red clover or perennial rye seeded at five to10 pounds, depending on what the field needs.
A common set-up in the four tanks might look like:
Tank one: Holds roughly 140 bushels and is filled with hard spring wheat. This will cover 70 acres.
Tank two: Holds 20 bushels and is filled with red clover which will cover 80 acres.
Tank three and four: These are fertilizer tanks. They hold 80 and 300 bushels respectively and will have 126 pounds of dry fertilizer (8-40-30) and monoammonium phosphate or potash.
This set-up allows Jade to seed multiple crops at the same time. The seed drill is capable of conventional or no-till. Jade utilizes controlled traffic farming[TH9] when he is in the field. This practice confines all machinery traffic in the fields to permanent lanes to restrict soil compaction.
According to Jade, “We utilize as much of our tools as we can and try to make it make sense or make it better.”
Planting Green Experiment: Conventional Tillage, Vertical Tillage and No-Till
The fields pictured show hybrid rye on June 9, 2023. The plan was to grow it for seed production, not as a cover crop. That year spring was late and wet, so the rye was thin, and fields had water damage.
Jade made the decision to plant green with soybeans under different tillage conditions. He tilled one part of the field using a Versatile Fury, which is like a Degelman Pro-Till high speed disc. In another part of the field, he used a Salford with wavy units to test how vertical tilling through the growth and matting would work. He also planted a section without tillage. He chemically terminated the rye the day after seeding it in June.
Jade says the no-till area yielded 1.8 bushels higher than the other areas, which isn’t a significant difference. The savings show up in the field preparation costs. Tilling a field costs Jade $17 to $30 per acre.
Frost-Seeding Red Clover
Jade started frost-seeding red clover into cereal rye to help control disease cycles and for the nitrogen credit. When he started this practice, nitrogen prices were at 90 cents to $1 per unit and clover seed and application was $35 an acre. Jade was happy with the results and felt like he was breaking even by planting clover and getting 30 to 40 units of nitrogen credit while also drying the overly wet soil profile out.
To get started frost-seeding, he bought a small pull behind seeding unit with 150-pound capacity to attach behind his side by side. That spring, he went out when most of the snow had melted and would spread seed for three to four hours in the early morning until the frost started to lift. After the rye was harvested later that summer, the clover took off and grew to thigh high by October.
He has now switched to an air boom system in a Case Titan spreader with multiple bins, and a micro-bin to put the clover on. He top dresses the rye with urea or ammonium sulfate or a blend of those. He has found that it is important to either work closely with someone at the co-op or have the equipment to do it yourself because the window of time to frost seed is so short, especially where he is in northern Minnesota.
Having his own equipment has also allowed him to plant red clover into his spring wheat. He will do this if he isn’t underseeding grass for seed production. Jade says he must be observant of the fields and their history, keeping track of chemical rotation restrictions and what weeds he would expect to have in the upcoming growing season. This is because he is limited by the herbicides that he can spray on spring wheat that will achieve some broadleaf control but not hurt the clover.
