In Iowa corn-soybean production systems, cover crops are typically aerially seeded into standing crops around the time of physiological maturity or drilled immediately following corn or soybean harvest. Previous on-farm research conducted by Jack Boyer has shown that seeding cover crops earlier in the fall can translate to greater fall and spring biomass. This may present […]

Seeding cover crops earlier in the
fall can translate to greater fall and
spring biomass and may present the
opportunity for more diverse cover
crop species selection.
• Early maturing varieties of corn (104-
105-day) and soybean (1.0 group) were
grown in southwest Iowa in an attempt
to harvest earlier in the fall and seed
cover crops earlier in the fall.
Key Findings
• Planting early maturing varieties of
corn and soybean generally did not
result in yield drag compared to the
late maturing varieties typically grown
in southwest Iowa. The exception
was in 2015 when the early maturing
soybeans yielded less.
• Cover crop biomass produced tended
not to differ between the early and
late maturity corn-soybean systems.
Seeding cover crops earlier in the fall,
following the early maturing corn
and soybean varieties, proved to be a
challenge

NEWS RELEASE

This year marks the 30th anniversary of Practical Farmers’ Cooperators’ Program. Since 1987, members have been conducting on-farm research to answer questions they have about their farming operations. It’s one of the ways we accomplish our mission: Strengthening farms and communities through farmer-led investigation and information sharing. The Research Protocols forms outlining research projects for […]

Objective: To measure if feed efficiency of a small gain (high-fiber) based diet increases when pelleted.

 

RESEARCH PROTOCOL

Objective: To compare nutrient density profiles of pork from conventionally raised pigs and pasture-raised pigs on full grain, 50% reduced grain and grain-free rations.

 

RESEARCH PROTOCOL

Objective:
The objective of this project is to measure the effects of apple cider vinegar (ACV) on milk quality, and over-all health of dairy cattle. We aim to see if acetic acid aids in fiber digestion; increasing milk components and cow health.

 

RESEARCH PROTOCOL

Objective: Determine if deep trench carrot yield is higher when grown in chopped leaves topped with soil, vs. soil only.

 

RESEARCH PROTOCOL

Objectives:
1. Determine whether multiple tillage passes (to decrease soil organic matter) is an effective control of scurf in Beauregard sweet potatoes. Scurf harms marketability and storage life of sweet potatoes.

 

RESEARCH PROTOCOL

Year 1 Objectives:
1. Determine differences in cost and labor for strawberry bed establishment using two methods: biodegradable plastic and mat row
