Agrochemical and biochemical properties of tipical chernozem soil under sunflower and vetch+oats in crop rotation in function of the fertilization system

Druța, Iana; Daraban, Oxana; Toma, Simion; Emnova, Ecaterina (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2011)

The aim of research was to study the impact of two fertilization systems on the agrochemical and biochemical properties of soil fertility. And how do they change under the influence of fertilizers use in crop rotation in ...
Biological activity of soybean rhizosphere soil in dependence on water content and nutritional status

Daraban, Oxana; Bîzgan, Iana; Emnova, Ecaterina; Toma, Simion (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2013)

Transformations of soil organic matter into easily assimilated nutrient forms by plants are mediated, to a greater extent, by soil microbiota. Soil biological activity characterizes both its fertility and the degree of ...
Enzyme activity in soybean root-adhering soil in dependence on nutrition and water content condition

Emnova, Ecaterina; Toma, Simion; Daraban, Oxana; Druța, Iana (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2012)

Exo-enzymes secreted by plant roots in common with microbial exo-enzymes are involved in soil biochemical processes, namely the processes of mineralization of soil organic matter and providing by mobile species of ...
Enzyme activity involved in n and p cycles, of soybean plant rhizosphere soil, roots and leaves

Daraban, Oxana; Bîzgan, Iana; Emnova, Ecaterina; Toma, Simion (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2014)

The research aim was to evaluate the influence of exogenous nitrogen sources on key-enzyme activity involved in nitrogen (urease) and phosphorus (phosphatase) metabolism in the rhizosphere soil, roots and leaves of soybean ...
Phosphatase activity of typical chernozem soil in field crop rotation

Daraban, Oxana; Zbanc, Elena; Emnova, Ecaterina; Boincean, Boris; Toma, Simion (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2011)

Soils of the Republic of Moldova are characterized mostly by a low content of mobile phosphorus. In the context of sustainable agriculture restoration and maintenance of soil fertility has become a key problem. The main ...
