In arable cropping systems, reduced or conservation tillage practices are linked with improved soil quality, C retention and higher microbial biomass, but most long-term studies rarely focus on depths greater than 15 cm nor allow comparison of microbial community responses to agricultural practices. We investigated microbial community structure in a long-term field trial (12-years, Lincoln, New...

Sorption-desorption interactions of pesticides with soil determine the availability of pesticides in soil for transport, plant uptake and microbial degradation. These interactions are affected by the physical and chemical properties of the pesticide and soil and, for some pesticides, their residence time in the soil. While sorption-desorption of many herbicides has been characterised, very litt...

Biochar is a solid material of biological origin obtained from the biomass carbonization, designed as a mean to reduce greenhouse gases emission and carbon sequestration in soils for a long time. Biochar has a wide spectrum of practical utilization and is applied as a promising soil improver or fertilizer in agriculture, or as a medium for soil or water remediation. Preparations of biochar incr...

Soil physic-chemical properties differ at different depths; however, differences in afforestation-induced temporal changes at different soil depths are seldom reported. By examining 19 parameters, the temporal changes and their interactions with soil depth in a large chronosequence dataset (159 plots; 636 profiles; 2544 samples) of larch plantations were checked by multivariate analysis of cova...

the effect of european black alder (alnus glutinosa l.) on the contents of carbon and nitrogen,exchangeable base cations, and plant available forms of phosphorus in the reclaimed mine soils formed bywaste deposition from opencast lignite mines was researched in central serbia. it was concluded that thegreatest part of dead organic residues reaching the soil under european black alder monocultur...

soil is a nonrenewable source that needs considerable management to prevent physical deteriorationby erosion and compaction. compacted soil causes low fertility and yield. the purpose of this study isto investigate the effect of viscoelastic properties of soil and to determine important factors oncompaction. furthermore, stress distribution, prediction of soil compaction and simulation of its e...

flood water contains high amount of sediment affecting the fertility of the coarse grain alluvial fans and flood plains through increasing nutrients. in this study, the effects of the flood water spreading on the soil nutrients recovery were investigated during 10 years (2004-2014) at the poldasht flood spreading station of west azarbaijan in iran. flooded three upper strips were selected at th...

to understand the relationship between natural physicochemical properties of soil and abundance of citrus root nematode (tylenchulus semipenetrans), a survey was conducted during 2009-2010 in some 37 citrus orchards, in kohgilouyeh va boyerahmad province, iran. distribution of the citrus nematode was determined by collecting random samples from the soil and citrus plant roots, extracting and en...

the superficial strata of ground have been perennially exposed to the action of natural agents such as heat, cold and water. however, grazing agent was not different from them when soils were investigated from temperate rangelands of kashmir and caused the soil compaction, soil structure degradation and loss of soil organic c and c/n ratio. soils from three grazing intensities were investigated...
