Soil water, soil chemical and crop variations in a clay soil
Spatial properties of field soils vary in a complex manner. Especially in arid and semiarid areas, this variability affects plant quality and crop production. An experimental field plot was extensively sampled regarding soil water (378 gravimetrical samples), soil chemical content (314 samples), and crop yield and chemical content (26 samples) at the Cherfech agricultural field research station...
متن کاملSoil and Water Management & Crop Nutrition
For the first few days after heavy rain or irrigations, water drains from the soil profile until its water content approaches a relatively stable value called the drained upper limit or field capacity. When plants have extracted all of the water available to them, the root zone water content approaches a lower limit of available water, or permanent wilting water content. The water held by the s...
متن کاملCrop management effect on chemical and biological properties of soil
This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3...
متن کاملEffects of Soil and Crop Management Practices on Soil Quality
Developing the concept of soil quality may help identify the soil and crop management practices required for environmentally, socially, and economically sustainable agriculture. Objectives of this paper are (1) to review current efforts to define soil quality, (2) to discuss factors and processes which influence soil quality, (3) to identify, soil and crop management practices that affect proce...
