Big Differences in Cover Crop Radishes

There are big differences in cover crop radishes.  Some are outstanding and consistent; deep and fairly large tubers (tuber girth seems to be related to fertility and age of stand).  In the thumb of Michigan I saw over 300 acres of fields planted at 10#/acre that were just what the farmer wanted.  We found most […]

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 […]

Cover Crop Radish Plot from July 10, 2010

My cover crop radish plot was planted on May 29, 2010 and now 6 weeks later we can see some characteristics even different from 2 weeks ago.  A variety that was 8-9″ deep 2 weeks ago still appears to have that same depth.  Another that I called “Stubby” is now looking quite interesting!  Yet another […]

Winter Cereal Rye

One of the most popular cover crops is winter cereal rye.   It is a very versatile cover crop that has few disadvantages.  While it does not have the deep, nor fibrous root system that annual ryegrass has, it reportedly has had 45″ deep roots found in north-central Indiana in May.  Winter cereal rye can be […]

Grazing Cover Crops in the Winter

Over the past 9 years I have worked with Ed Ballard from the University of Illinois on grazing cattle over the winter. During the first 4-5 years I was much more concerned about the “above ground” aspect of the cover crop and weight gain by the animals. However, these past 4-5 years have shown me the […]

How deep can radish roots go?

After 6 weeks my GroundHog Radish is around 12″ deep and 1″ in circumference at the top.  How deep can radish roots go?  Because we need to know things like that I have been doing quite a bit of research.  The attached chart shows how deep some radishes can go…over 4 feet deep!  WOW!

Radish Plot Report from June 26

I planted a cover crop Radish plot over Memorial Day Weekend (5/29) in my garden plot.  I have 5 varieties in the plot from around the world.  My goal is to see what differences there are in the different Radishes being sold in the USA for cover crops.  I replicated the plots so that each […]

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 Radishes – differences in varieties

On May 29th I planted 6 different cover crop radish varieties in a plot.  In those 16 days we’ve had good moisture, and I did apply some 30-0-5 fertilizer around 60 days ago (with slow release N).  I had to thin the plots to have 1 radish per 4″ (recommended distance between radishes by those […]
