A method of increasing the fertility of the rooting layer of derno-podzolic soils


, : A method of increasing the fertility of the rooting layer of derno-podzolic soils. Doklady Vsesoyuznoi Ordena Lenina Akademii Sel' skokhozyaistvennykh Nauk Imeni VI Lenina (9): 22-25

A micro-plot experiment on a derno-podzolic soil showed that placement of farmyard manure (100 t/ha) at depths of 25-30 cm or 30-45 cm improved the fertility of the soil for a period of 5-6 years and increased the productivity of a crop rotation by 61.3-65.1 feed units per ha.

A GABAergic component has been identified in the projection from the inferior colliculus (IC) to the medial geniculate body (MG) in cats and rats. We sought to determine if this GABAergic pathway exists in guinea pig, a species widely used in audi...

Sudden death syndrome, caused by Fusarium virguliforme, and the soybean cyst nematode, Heterodera glycines, combined cause the highest yield losses in soybean. The objective of this study was to determine the effectiveness of corn rotated annually...

MicroRNAs (miRNAs) have been shown to influence erythroid lineage commitment and differentiation; however, our knowledge of miRNA function in terminal erythropoiesis remains limited. To address this issue, we generated a novel animal model, where...
