In crop rotation with following crop alternation fi eld pea for green mass – winter triticale + clover – meadow clover of one year – summer wheat – summer rapeseed on sod-podzolic light loamy soil has been studied the removal and nutrients balance depending on various fertilization systems. Nitrogen balance in fertilization system with doses calculated for defi cit balance of these elements amounted to 19,9-31,4 kg /ha, with doses calculated for maintaining balance - 15,0-32,0 kg/ha. Positive phosphorus balance 12,9 kg/ha has provided with application 280 kg/ha active matter phosphorus fertilizers for alternation crop rotation. Potassium balance in all fertilization variants was negative and depending on the investigations amounted from 60,6kg/ha to 68,9 kg/ha. |
