Arid-Zone SoilsThe soil (pedosphere) is the active transition zone between the lithosphere and the atmosphere where the various processes responsible for the transformation of matter and energy occur. The same may be said for plant and animal life (biosphere), so that sometimes both may actually comprise one active unit (the ecosystem, according to ., 1961).

Nutrient Supply to Irrigated Cropsilizers and manure. The choice of a specific fertilizer, and the amount to be used in a given case of irrigated agriculture, depend on the kind of crop, the state of plant development, the time of application, the kind of soil and nutrient residues in the soils, the price of unit nutrient in the field, and the irrigation technology.
