An In Situ Videotaping Approach for Parameterizing Subsoiling-Induced Soil Disturbance
نویسندگان
چکیده
Subsoiling (SS) is an important technology in conservation tillage, but soil-disturbance characteristics the SS are rarely described. Research on during conducive to design and optimization of subsoilers, which provides a basis for reducing draft force energy consumption. This study conducted experiments at five different tillage depths field with specific situ test-rig facility, videotaping was made from positions SS. The microrelief test, disturbance cross-section test process analysis were after results showed that increased depth as quadratic function. Soil displacement parameters soil crack extracted video significantly correlated depth, could be used quantitative description paddy characteristics. Cross-sectional area trend “increasing then decreasing” increasing reaching maximum 20 cm. When greater than cm, bottom disturbing boundary formed “mole cavity”. Fallback rate describe change disturbed height or width SS, exceeded 100% maximum. surface roughness size average clods reached Considering shallow cultivation layer rice–wheat rotation, recommended cm achieve minimum consumed.

Does Soil Disturbance Affect Soil Phosphorus Fractions?
Increased turnover of organic matter as a result of soil disturbance (e.g. by soil tillage) is described in principle, but the direct influence of soil disturbance on soil P turnover especially for organic farming systems has not been sufficiently proven. The objective of the study was to evaluate the short term effect of soil disturbance on different soil P fractions in a soil shaking experime...
