fit into extended and diversified
crop rotations between the
small grain and corn phases of
the rotation. They can either be
underseeded with a small grain
crops in early spring or planted
in the summer following small
grain harvest.
• Farmer-cooperators Doug
Alert & Margaret Smith and
Vic Madsen compared corn
following two green manure
strategies: red clover or alfalfa
underseeded with oats (US) vs. a
mix of sunn hemp, sweet clover,
red clover and radish planted in
mid-summer after oat harvest
(MSS).
Key Findings
• Weed biomass in oats in mid-July
was no different with or without
the underseeding at both farms.
• By mid-October 2016, the US
(red clover) produced more
aboverground biomass than
the MSS by almost 1,000 lb/ac
at Alert/Smith’s. The opposite
was true at Madsen’s: the MSS
produced more biomass than the
US (alfalfa) by approx. 800 lb/ac.
• Corn yields were no different
between the two green manure
treatments at both farms.

RESEARCH REPORT

By now, small grains have been planted and farmers have turned their attention to planting corn, and later to soybeans, but farmers must remember to continue to monitor small grains development during this busy planting time in order to achieve good quality grain. The March 10 shared learning call focused on best practices for fertilizer, […]

BLOG POST

On January 21-22,  around 85 farmers from across the state gathered in Ames to learn about small grains crops (oats, wheat & barley) from industry professionals, researchers and fellow farmers at the “Growing Good Small Grains” course prior to Practical Farmers of Iowa’s annual conference. Most Iowa farmers spend plenty of time thinking about plant populations, plant protection products and fertilizer requirements […]

BLOG POST

Join experienced farmer Bill Frederick and beginning farmer Dustin Farnsworth as they share their experiences with growing small grains as part of the rotation on their Iowa farms. Small grains researcher David Weisberger will then share insights he gained from talking with organic oat producers across the state. This farminar will focus on the practical aspects of successful small grains: field preparation, plant populations and planter settings, stand assessment and harvest tactics.
