The effects of long term no-till and crop residue on soil microbial community catabolic function and relevant carbon cycle in the rhizosphere and bulk soils were assessed in the 10th year of a maize-winter wheat-soybean crop rotation. Conventional and zero tillage were coupled with residue removal and residue retention in a factorial design. Soil microbial community catabolic diversity was dete...

To study Assessing the impact of tillage practices on soil carbon losses dependents it is necessary to describe the temporal variability of soil CO2 emission after tillage. It has been argued that large amounts of CO2 emitted after tillage may serve as an indicator for longer-term changes in soil carbon stocks. Here we present a two-step function model based on soil temperature and soil moistur...

Agriculture is facing a major challenge nowadays: to increase crop production for food and energy while preserving ecosystem functioning and soil quality. Argentine Pampas is one of the main world producers of crops and one of the main adopters of conservation agriculture. Changes in soil chemical and physical properties of Pampas soils due to different tillage systems have been deeply studied....

the objective of this study was to determine the quicker response of subsoil or surface soil to minimum tillage (mt) and conventional tillage (ct) and biofertilizers (bacillus coagulans, b), phosphorus fertilization (p) and integrated p and b (pb) under the wheat (triticum aestivum l vr. sardari) growing season. the experimental design was split plot laid out in randomized complete block design...

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 ...

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...

Your tillage system is important to the long-term sustainability of the farm enterprise. Matching a crop tillage system that is suited to your farm resources can provide both economic and environmental benefits. It is important to evaluate your land and determine what options would be appropriate. Several questions have arisen regarding new approaches or options in tillage systems compared to a...
