(4) Despite strong changes in soil physical properties under conservation tillage, pesticide transfer is more influenced by initial soil conditions and climatic conditions than by tillage. Conservation tillage systems such as no-tillage improve macropore connectivity, which Cited by: This study, conducted in , researches the effects of different tillage practices on the physical soil quality of clayey soil. This soil quality index (SQI) assessment was made by studying the changes in physical soil functions such as suitability for root development, facilitation for water entry, movement and storage, and resistance against surface degradation based on tillage by: 5.
Residue cover is widely used for soil conservation after crop harvesting in the black soil region of the Northeastern China, which influences infiltration. It is necessary to optimize infiltration models for accurate predictions under bare and residue cover slope conditions. Rainfall simulation experiments were conducted to quantify the infiltration for the black soil under four rainfall Author: Yan Xin, Yun Xie, Yuxin Liu. Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. A sequel to the deforestation is typically large scale erosion.

Various soil fertility management techniques have been put in place to improve soil fertility status, but there is little attempt to asses their effects on water use efficiency and grain yields.
The simulated soil water content in the profile under the ESL matched the measured soil water content under crop residue cover with RMSE values of to cm 3 cm -3 for calibration and 0. conservation tillage were developed. Pilot studies on conservation tillage techniques were set up which were suitable to different types of drought areas, mainly those with few (no) tillage, furrowing drilling, mulching, intercropping and rotation.
Of these techniques, soil and File Size: KB. At #FSFS17, Dr. Wayne Lindwall & Dr. Ben Ellert talk about the effects of soil management styles on water available to plants over the growing season.
They. Our objective was to quantify the effects of NT and SM on stored soil water, runoff, and deep drainage through a clay loam soil in relation to crop growth and yield.
Wheat (Triticum aestivum L.) and grain sorghum [ Sorghum bicolor (L.) Moench] were grown in paired tillage treatments using a 3-yr wheat–sorghum–fallow (WSF) rotation from Cited by: 6. Biomass removal and soil trampling without tillage, however, may reduce rain infiltration and storage during fallow that increases with no-tillage (NT) over stubble-mulch (SM) tillage.
Our objective was to quantify grazing and tillage effects on infiltration, sediment transport, and aggregate stability during fallow periods after sorghum and by: 1. This paper analyzes the relationship between runoff, soil erosion, sediment particles, and natural rainfall characteristics on sloping farmland in the red soil region of southern China.
The surface runoff and soil loss data were measured on runoff plots during 66 natural rainfall events from to in Jiangxi Province. The results show that the maximum min rainfall intensity (I30) is.
Soil conservation stores more of the runoff from excess rainfall in the reservoir of the soil for subsequent crop use; and this much water is kept out of streams, thereby contributing to flood reduction. Today these techniques of soil and water conservation are being prac- ticed in many countries with much benefit to great numbers of people.
The rate and quantity of evaporation from the soil surface is a complicated process affected by many soil characteristics, tillage and environmental interactions (Lal & Shukla, ).Under conservation tillage, higher water content in the topsoil and more plant residues on the soil surface, resulting in declined evaporation, have been linked with the lower soil temperature (Rasmussen, ).Cited by: Citation: Effect of mulching on soil and water conservation -A ltural Reviews(38) Ezeaku P.I.

Soil compaction in no-tillage soils was not found to be a problem. Saturated hydraulic conductivity measurements suggest better water movement in no-tillage compared with conventional tillage. After 10 years of continuous no-till corn production, no deterioration of soil physical properties was observed.
This year project has systematically compared the impact of long-term conservation tillage (i.e. no-tillage, full residue retention) with that of conventional tillage (mouldboard plough, all residue removed), in terms of soil bulk density, soil aggregation, porosity, soil fertility, soil available water, winter wheat yield, and water use.
