Why was this not good for your use??
""
The ryegrass, bromegrass, orchard grass combo I planted last spring turned out not to be a good choice that wasn't discovered until harvest. But, it may be just what you want.""
My orchard is 600 pecan trees that I mechanically harvest. After shaking the trees, the next step is to sweep them into rows. The grass combo tended to clump more so than I thought it would when I planted, and when the sweeper was in the trial section of grasses, the nuts would "hide
" around the clumps of grass and not get harvest. We walked through the heaviest sections of grass and picked 50-100 lbs of pecans by hand. Where the stands of grass were thin, everything was fine.
The recommendation for the grass mix came from a friend of a friend who has about 16 trees, hires out the work and doesn't care how his crop turns out. That'll teach me.
Only 1/2 of the rye grass was perinial so everything else should die soon, and if I keep the rye mowed down maybe it won't reseed and I can find something else to plant that will choke it out.
Research for the clover and alfalfa was done a little better. We walked trough local fields of alfalfa and it was very thin stalks and didn't clump. I talked to extension agents and researchers in South Texas and California about the clover and they've seen it many pecan orchards without the clumping and harvesting problems. My research suggests that the vetch is similar to the clover, but I'm not sure abou the medics.
Chicken food was actually an afterthought when I planted these. My original goals were fixing nitrogen from the air, preventing any more soild and wind erosion, start a no-till program in the orchard, heat and drought tolerant(two years ago we had over 100 days over 100 degrees and on of them hit 116), bring in benificial insects, and get some organic matter into the soil.
I planted the alfalfa in some very young trees to se how well it will grow so that if we can acquire more land in the future, it will be planted in the new trees to serve as a cash crop while we wait 10-12 years for the pecans to start producing.
The clovers fit the bill really well to a degree so I tried yellow(sweet) and white. The yellow has better drought tolerance and the white has better shade tolerance. We'll see how things go this year, I may plant some medic and vetch.
