Our results suggest that tillage type was a more important factor in the question of yields than either the highly variable climate of the studied years, or the diverse slope conditions of the plots. During the first three years of technological changeover to CT (20032006), a decrease of 8.7...
Conventional tillageConservation tillageYieldCrop response and Principal component analysisPrincipal component analysis is a valid method used for data compression and information extraction in a given set of experiments. It is a well-known classical data analysis technique. There are a number of ...
The two-pass, combination, tillage technique, followed by a conventional cereal drill or roller drill, gave similar oil yields to the conventionally ploughed, cultivated, and roller-drilled plots. There is potential to reduce the cultivation inputs (and, hence, the inherent costs) by combining ...
It is also concluded that the conservation tillage could result in a rather bigger increase of winter wheat yield in a drier year than in a less drought or wet year as comparing to conventional tillage. Key words: dryland farming,conservation tillage,notill,sustainable development...
The Influence of Conservation Tillage and Conventional Tillage on Soil Bacterial Diversity in Southern Illinois 来自 掌桥科研 喜欢 0 阅读量: 72 作者: Syed, Nasser. 摘要: Agriculture in the Midwest United States (Illinois, Indiana, Iowa, Michigan, Minnesota, Ohio, and Wisconsin) is a critically...
Soils were collected from fields at 0–5 and 5–15 cm depths to study the effects of tillage (conservation vs. conventional) and cover crop (with vs. without) on soil stocks of various chemicallyヾefined P pools and the phosphatase potential activities (PHO). Conservation tillage increased ...
In this study, we monitored weed seed predation rates of Viola arvensis and Capsella bursa-pastoris and carabids from March to September using a grid sampling in two adjacent winter-wheat fields, one in conventional tillage (T) and the other converted to direct drilling with cover-crop for ...
The results quantify the increased amount of C that is sequestered when these residues are used in conservation tillage compared to conventional tillage. This research implies that the use of biomass cover crops and in situ organic mulches could have a measurable impact on carbon retention rates, ...
Losses of particulate P decreased, but dissolved P increased with no-till, cover crop. Tillage increased erosion of fine-textured soil and associated particulate P into tile drains. Greater fertiliz...
Under agricultural land use, the properties of the macropore network are governed by the applied management and tillage system. On an experimental site with a silt loam soil partly under conventional and conservation tillage, the methods of visual inventarization of stained and unstained macropores...
