Ahead of our annual conference last month, we held a short course titled “Conserving $$ and Soil.” Often the conservation of farm production input costs and soil might be considered at odds with one another. Soil conservation efforts are thought to cost money to implement and/or they might involve producing less which would in turn lose […]

Since 1987, the Cooperators’ Program has been Practical Farmers of Iowa’s vehicle for conducting on-farm research on the issues and concerns deemed most important by our members. The Cooperators’ Program is the epitome of what PFI is all about: Farmer-led investigation and information sharing. In 2015, 63 farmers took part in 35 research projects on […]

Delaying cover crop termination until soybean planting would allow for more biomass production by the cover crop in the spring presenting the opportunity for more environmental benefit. A newly released research report profiles the findings of farmer-cooperators who seeded soybeans 10-14 days after terminating a cereal rye cover crop and within 1 day of terminating the cover crop. The objective of this […]

Fruit and Vegetable farmers use cover
crops to improve nutrient cycling
and control weeds for increased
production efficiency.
• Summer cover crops can be challenge
due to dry conditions.
• Four farms evaluated summer cover
crops to determine aboveground
biomass production, carbon and
nitrogen produced, effects on
subsequent cash crop germination
and effects on subsequent weed seed
• Summer-seeded cover crops produced
between 192 and 14,157 lb of
biomass per acre across the farms.
Species selection, location and days
of cover crop growth tended to dictate
biomass production.
• Not surprisingly, legume species
contained more N than nonlegumes,
though buckwheat also
tended to contain a large amount
of N.
