Shuglya Z.M.
Phosphorus balance and dozes of fertilizers under different systems of fertilization in crop rotation have been examined while many years field experience was realised by Grodno Zonal Research Institute of Agriculture. Four field crop rotations have been carried out on sod-podzolic sandy loam soil with the following crops: 1-3 rotation buckwheat, winter rye, potato, barley; 4-5 rotation, instead of planting buckwheat was used vico-oats mixture. It was defined that the optimal phosphorus balance on sandy loam soil should be 198-210 per cent.
