BACKGROUND Tillage practices greatly affect carbon (C) stocks in agricultural soils. Quantification of the impacts of tillage on C stocks at a regional scale has been challenging because of the spatial heterogeneity of soil, climate, and management conditions. We evaluated the effects of tillage management on the dynamics of soil organic carbon (SOC) in croplands of the Northwest Great Plains e...

Soil water and temperature are important factors to reflect variations in soil heat flows especially for tillage systems. The objective of this study was evaluate the performance CoupModel predicting effect practices on processes conventional (CT) no-tillage (NT) systems with straw mulching semi-arid high-latitude Mollisols northeast China. This model calibrated evaluated a three-year experimen...

During decades, in semiarid rainfed Aragon, intensive soil tillage and low crop residue input have led to the loss of soil structure and soil degradation. Conservation tillage and cropping intensification can improve soil structure in these areas. The objective of this study was to determine the influence of three different tillage systems (traditional tillage, reduced tillage and no-tillage) u...

Conventional and conservation tillage systems can alter soil aggregation total labile organic matter (SOM) contents. This study aimed to determine the degree of aggregation, quantify carbon (TC), permanganate oxidizable (POXC), light (LOM), potentially mineralizable (CO2-C) contents in soils aggregates, assess quality indexes at sites under conventional Cerrado region Minas Gerais State, Brazil...

Abstract The objective of this work was to evaluate cassava (Manihot esculenta) crop yield, as well soil density and carbon content, under no tillage conventional cultivation, in rotation with palisade grass (Urochloa brizantha) subjected grazing. Treatments consisted cultivated follows: after 2 (CC-2P) 4 (CC-4P) years pasture; no-tillage (NTC-2P) (NTC-4P) perennial pasture (PP) grass. CC-2P tr...

many farmers periodically use deep tillage operations to alleviate compaction in the soil profile caused by natural factors or machinery traffic. in 2012 and 2013, a study was initiated in the pannonian region of croatia to study the effects of no-tillage (nt), conventional tillage (ct) and deep tillage (dt) on soil compaction, measured by (bd), soil water content (swc), penetration resistance ...
