Razec, M. (Grassland Research Institute, Brasov (Romania))
During period of three years the influence of five pHH20 levels (4.53-6.62) and five levels of mobile Al content (102-0 ppm) on the DM yield and chemical composition of white clover plants were studied under greenhouse conditions. Improvement of the soil pH and resultant decrease of mobile Al content in the soils increase DM yield from 1.2g pot (-1) to 13.8g pot (-1) and at the same time improved the chemical composition of the forage. There was increase in macroelement content (N, P, Ca, Mg) in the herbage for animal nutrition and a decrease in trace element content (Fe, Mn, Cu, Zn, Al) from values, potentially toxic to animals, to values close to those optimally required in animal nutrition. All low pH H20 4.53 to 5.33 toxic quantities of Fe, Mn, Al can be translocated to the aerial parts of the plant
