The efficiency of rhizobia use in the soybean cultivation on chernozem of the Western Ciscaucasia
In the period of 2008-2014, we carried out the field experiments to evaluate the efficiency of soybean inoculation with Russian and foreign preparations of nodule bacteria on various subtypes of chernozem of the Western Ciscaucasia.

ABSTRACT Species in grasslands restored from former arable land have multiple obstacles when establishing. Understanding whether these limitations stem from soil chemical or microbial differences could help to create suitable environments for specific target and other species with similar requirements.

Predators are important regulators of grassland biodiversity and ecosystem functioning, but their top‐down effects on detrital food webs under global change remain poorly understood. Using a field mesocosm experiment in a temperate grassland, we show that drought and nitrogen addition independently altered the effects of wolf spiders on soil fauna and ...

When setting a long-term field experiment in order to study the impact of direct sowing technology on soil properties it is necessary to take into account not only the known requirements, but a comprehensive analysis of soil heterogeneity as well.

Abstract Soil organic carbon (SOC) dynamics and greenhouse gas (GHG) emissions in dry (arid and semi‐arid) agroecosystems are regulated by low and variable moisture, episodic wet–dry cycles, and limited organic inputs. Although process‐based biogeochemical models are widely used to quantify these processes, a comprehensive assessment of their ...
