Aerial Application of cover crops — an art or a science…or both?

I have heard that a number of aerial applicators admit that they are guessing approximately how wide they need to fly to apply different cover crops. I have seen evidence that some of them have guessed wrong!  Two or three years ago an applicator guessed wrong by leaving approximately 80’ wide gaps in a number […]

Radish planted with wheat (at seeding time) adds yield? There are a bunch of farmers saying “yes, it does!”

While in northwest Ohio in the Fall of 2010 for a manure management field day, some area farmers told me that wheat producers are adding 2-4# of cover crop radishes per acre to the wheat in the drill…and experiencing excellent results. Some reported gaining 5-7 bushels per acre by adding the radishes.  Others even reduced their nitrogen application by 20% […]

Is Annual Ryegrass a weed – part 2

Today, August 3, 2010 I visited some fields in Whitley County Indiana to look at fields where annual ryegrass was not killed quite perfectly this spring.  Even though the soybeans look awesome there is a problem lurking under the bean canopy.  That problem is a fairly thick stand of annual ryegrass.  I found ryegrass in […]

Cover Crop Radish – Rate Per Acre

In my cover crop radish plot I have thinned some rows to 4″ between plants and in two rows I have left them thick (I figure I’m at the 12-15#/acre range). After 6 weeks there are some pretty telling signs that 12-15#/acre is too thick and possibly a waste of money.  Most of the varieties […]

Crimson Clover; a jewel among the cover crop legumes

Crimson clover is a real jewel among the cover crop species.  Crimson clover is an excellent producer of nitrogen and there are some newer varieties on the market that are very winterhardy even into Michigan.  Dr. Eileen Kladivko measured how much nitrogen was produced by crimson clover in a test plot in western Indiana.  What […]

Cover Crop Selection – What to plant after wheat or other cereal grains?

I was in a meeting yesterday and the gentlemen from SWCD asked me: “What should we recommend for our producers to plant as a cover crop after the wheat comes off?” After running through a number of scenarios I determined that I’d better make sure I don’t confuse folks with too many ideas.  So, here […]

When to aerial apply cover crops into corn

A few years back many said “August 15-25” was the right date to aerial seed cover crops into corn.  However, we found out very quickly that “dates” cannot be set…but timing can be.  While we know that August 15-25 often can be correct, we also know that following the calendar (like in the 2009 crop) […]

Cover Crop Seeding rates DO matter

As an agronomist I try real hard to recommend the correct seeding rates.  For instance the “recommended” seeing rate on radishes has been 10-12#/acre but in reality only 3-5#/acre does a lot of good in mixes and 10-12 is WAY too thick (and expensive).   Annual Ryegrass rates for cover crops is 1/2 that for forage.
