AbstractThe changes in the physical properties and carbon stocks of dark-humus podbels (Luvic Albic Mollic Planosols (Epiloamic, Endoclayic, Aric)) during long-term agricultural use and postagrogenic evolution were studied. Soil samples were taken in three trials: control (without fertilizers), high rates of mineral fertilizers, and mineral fertili...

Microplastic as an anthropogenic pollutant accumulates in terrestrial ecosystems over time, threatening soil quality and health, for example by decreasing aggregate stability. Organic matter addition is an efficient approach to promote aggregate stability, yet little is known about whether microplastic can reduce the beneficial effect of organic ma...

AbstractSpecific features in the content and accumulation of organic carbon and nitrogen in the aggregates of typical chernozems (Protocalcic Chernozems) of long-term experimental plots with different land management systems are assessed. The size fractions in the aggregates of >10, 10–3, 2–1, 1–0.25, and 10 and

Abstract—The specific features in accumulation and distribution of organic carbon and nitrogen in the aggregates of typical, ordinary, and southern chernozems (Protocalcic Chernozems, Endocalcic Chernozems, and Pantocalcic Chernozems, respectively) during the transition from conventional farming to a no-till system are evaluated. For this purpose, ...
Soil bulk density (BD) is a key soil property in soil science. BD is measured at the scale of the soil horizon with conventional methods: core sampling and rubber balloon. Regardless of the method, BD measurement in the field is cumbersome and time consuming, especially in stony soils, and new, less invasive methods have emerged, but their measurem...

AbstractThis article presents the results of the study of a new soil structuring agent—the interpolymer complex of a chitosan biopolymer and a synthetic polymer of polyacrylic acid—applied to the surface layer of a light chestnut soil (Kastanozem) in the East Kazakhstan region. The interpolymer complex was obtained by mixing equimolar polymer solut...

Soil microbial communities play critical roles in maintaining natural ecosystems such as the Campos biome grasslands of southern South America. These grasslands are characterized by a high diversity of soils, low available phosphorus (P) and limited water holding capacity. This work aimed to describe prokaryotic communities associated with differen...

Scientific studies show that the efficiency of biochar can be improved by its combination with other fertilisers. For this reason, fertiliser manufacturers are working to create products that combine biochar with other soil fertility enhancers suitable for different soil-climatic conditions. In this study, two types of biochar substrates (1. biocha...

AbstractThe extractable fractions of organic matter (OM) differing in their mobility—water-extractable organic matter, labile humic substances, and humic substances—have been isolated from different-sized aggregates of a typical chernozem (Haplic Chernozem (Loamic, Pachic)). The first two fractions characterize the active OM pool, and the latter fr...
