Using recycled water culture system the optimun concentrations of N, P and K as well as the ration between ammonium and nitrate in the solution is determined forthe maximum seed yield and seed germination vigor.
Recycled water in surface and subsurface trickle irrigation is tested on the uptake, N balance in field grown corn, and its effect on coli contaminants as well as on plant composition and fodder quality.
