Effect of lead soil pollution on the soybean productivity and quality

Abstract

In the small plot experiment with the different background of the soil contamination by the lead the close relation was defined between its content in the soil and its presence in the crop elements. Mineral fertilizers in high dosage influenced upon growth of the content of total and mobile forms of lead in the soil and promoted to decrease its intrusion into the plants. Excess of extreme admissible concentration of total and mobile forms of lead in the soil decreases soybean production. Mineral fertilizers increased carrying out of lead in straw and poorly influenced upon its content in the grain. Accumulation of lead in straw directly depends on its quantity in the soil.
