They do need water at the right time. First you need to check and correct the PH before anything else. WVU will soil tests for you thru the county extension agency. They will tell you the PH and how much lime you need. If you let them know what you are planning on planting the will give a recommendation on fertilizer.
I've been real happy with buckwheat for summer plots. Plant the first of may and cut down the end of August. Then replant with buck forage oats and/or winter wheat for the fall.
I usually plant Imperial whitetail clover along with winter wheat or rye (not ryegrass) in the fall. the wheat/rye acts as a cover for the clover during the fall, then the next spring I cut the wheat/rye down after the clover has taken off. I get about 4 years out of each clover planting. I fertilize the clover late winter with a low nitrgen high phosphate and high potassium fertilizer. I usually use a 10/20/20 on the buckwheat and a 19/19/19 on the oats and wheat.
this is the first year I mixed the forage soybeans and summer peas with the buckwheat and I'm very pleased so far.
To plant I cut everything down then as they are just starting to green up, spray with glyphosate and wait till it dies. best to wait 5-7 days, Then I fertilize then till the ground. Then broadcast the seeds and use a cultipacker to get good seed dirt contact then pray for rain. I usually try and watch the forcast and plant 1-2 days before a good rain is forcast.
