Relationship of irrigation water salinity and soil water salinity

California Agriculture, 1983
Significant concentrations of soluble salts are not normally found in organic soils. Organic soils, differentiated from mineral soils by an organic matter content greater than 20 percent, are formed from partially decayed plant remains that accumulated ...

MICROECONOMICS OF IRRIGATION WITH SALINE WATER

Journal of Agricultural and Resource Economics, 2002
Water management and reuse at the field level are analyzed under saline, limited drainage conditions. A function relating crop yield and deep percolation flows to applied water and salinity concentration is developed. This function fits simulated data well and is tractable for theoretical and empirical analysis of irrigation economics.
