The article presents information on the moisture state and nutritional regimes depending on the fertilization level of the leached chernozem, following the systematic and long application of fertilizers in rotation. New data were obtained regarding the humus content, mobile phosphorus and exchangeable potassium. The natural background (control variant) of the leached chernozem is characterized by a relatively optimal content of humus (3.40-3.45%), very low mobile phosphorus (1.1-1.5 mg/100g) and relatively optimal potassium exchangeable (24-29 mg/100g). On the fertilized varieties, humus is relatively optimal (3.49-3.57%), mobile phosphorus is moderate and varies from 2.2 mg to 3.4 mg/100g, exchangeable potassium - from relatively optimal to high (28-34 mg/100g). Nitric nitrogen reserves at spring in the control variant in the 1 m layer of soil varied from 13 kg/ha to 72 kg/ha, on the variants long fertilized, the nitric nitrogen reserves in the soil were 17-45 kg/ha for winter wheat and 69-145 kg/ha for hoeing crops. |
