Productivity of corn grown in the crop rotation and as monoculture under long-term fertilizing
Productivity of corn grown in the crop rotation and as monoculture under long-term fertilizing In 1971-2015 on the Voronezh leached black earth there were conducted the researches of the effect of long-term use of various kinds, doses, combinations of fertilizers in the 10 crop rotation sequences an...

It has been determined that the yearly N60Р60К60 fertilizing increased the productivity of green chop, dry matter and corn grain on 8.8, 2.53 and 1.29 t/ha in crop rotation and on 10.1, 2.71 and 1.32 t/ha in monoculture in comparison with the productivity of green chop, dry matter and corn grain without fertilizing (26.2, 6.42 and 3.42 t/ha in crop rotation; 22.1, 5.65 and 2.81 t/ha in monoculture). Due to the crop rotation the increase of green chop, dry matter and corn grain productivity was 2.4-4.1; 0.3-0.8 and 0.5-0.6 t/ha respectively. The largest content of organic carbon was estimated in the topsoil. The archive soil sample contained 3.19% of carbon; in black fallow (since 1960) it was 3.12%; in corn-corn monoculture without fertilizing it was 3.37% and with the yearly N60Р60К60 fertilizing it was 3.42%. In the soil layer of 60-80 cm there were no significant differences in the amount of organic carbon.https://www.zhros.online/jour/article/view/71corncrop rotationmonoculturemineral fertilizersproductivitysoil carbon |
