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...

Abstract The investigation was conducted in the 2019–2020 agricultural season Al-Thaghr area, north of Basrah Governorate, Iraq (latitude 31.145288N and longitude 47.431334E), clay soil. Two factors were used investigation. first factor three tillage systems (heavy by mouldboard plow, low chisel no-till system). second concentrations biocide Trichozon (4 g m -2 , 2 without adding pesticide). ex...

tillage usually has been found to increase b compared with moldboard and chisel plow (Kitur et al., 1993; Lal, Tillage impacts on soil properties differ among soils. This study 1999). Bulk density usually is lowest immediately after investigated tillage, cropping, and wheel traffic (WT) effects of 13-yr of no-tillage (NT), chisel plow (CP), and moldboard plow (MP) under tillage and increases wi...

Abstract In areas with a pronounced relief, water erosion causes great harm to agriculture and other sectors of the national economy. It leads destruction soil cover, reduction in area arable land, decrease fertility, removal products into floodplains, siltation ponds rivers road network. The scientific goal was identify influence main natural factors (snow reserves, freezing moisture) on forma...

Mechanized agriculture is increasing rapidly in the Cerrado region of Brazil, causing concerns about water quality, off-site impacts, and sustainability. Our objective was to determine the impact of tillage on soil biological activity and aggregate stability in an Oxisol typical to the region. Three different tillage practices common to the Cerrado region (no-till, disk harrow, and disk plow) a...

in order to investigate the effect of wastewater and compost on transport of heavy metals in a soil column, a factorial experiment based on completely randomized design with three replication was conducted. the variables included three types of water: fresh water (w1), treated wastewater (w2) and a composition of 50% raw wastewater and 50% fresh water (w3). besides, four levels of compost were ...
