Reducing tillage intensity and plant residue retention have the potential to mitigate climate change by reducing soil greenhouse gas emissions. Few comparative studies explored effects of different practices on net balance GHG emissions in short term (1–2 years). We hypothesised that decreases compared conventional ploughing removal. estimated practices; no-tillage, minimum-tillage traditional ...
Agriculture is the single biggest user of land and water in Morocco; however its performances are still low due to high rainfall variation and rates of soil productivity depletion. Increasing concerns about soil and environment quality degradation have raised the need to review existing tillage management systems and develop new systems for seed-bed preparation. Consequently, No-tillage is foun...
irrigation management, soil tillage method and fertilizer management play important roles in increasing crop yield and water and solute movement in the soil profile. the present research was conducted to study the effects of a no-tillage system and nitrogen fertilizer on the mineral nitrogen movement and soil moisture under optimum irrigation conditions. the study was conducted at safiabad agri...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
With the modern development of agricultural production, introduction resource-saving technologies, technologies based on intelligent systems, there is a need to introduce system machines for implementation surface tillage (mini-till, no-till). The main factor largely determining choice an machine, its working bodies, and processing technology are agrophysical properties soil. research was exper...
This study was aimed at analyzing the yield, grain quality and weed infestation of spring triticale sown in 3 tillage systems: a) conventional tillage (CT)-shallow ploughing and harrowing after harvest of the previous crop, ploughing in the autumn; b) reduced tillage (RT)-only cultivator after harvest of the previous crop, and c) no-tillage (NT)-only glyphosate (360 g L-1) after harvest of ...
The experiments were conducted at Green Acres Agronomy farm near Gainesville, Florida, on an Arredondo loamy sand, a member of the loamy, silicious, hyperthermic family of grossarenic Paleudults. The field study started in 1976 included cropping systems of oat (Avena sativa)/soybean (Glycine max L. Merr.) versus oat/grain sorghum (Sorghum bicolor L.) that were split plots of four tillage treatm...
Excessive harvest of corn (Zea mays L.) stover for ethanol production has raised concerns regarding negative consequences on soil physical quality. Our objective was to quantify the impact of two tillage practices and three levels of corn stover harvest on near-surface soil physical quality through the Least Limiting Water Range (LLWR). We evaluated no harvest, moderate and high stover harvest ...
