Excess irrigation is the short answer. If you consider a body of fresh water penetrating the sub strata, it is clear that any salt at all that it encounters will be quickly 'absorbed' into the.

Trifluralin leaching in soils cultivated with sugarcane irrigated by Sub-surface drip system Article (PDF Available) in IRRIGA 17(1) January with Reads How we measure 'reads'. -: Salinity and sodicity are soil conditions that occur mainly in arid and semiarid regions. Rainfall leaches salts out of soils in humid regions, and salt problems are rare and transitory. Ions that contribute to soil salinity include Cl-, S, HC,Na+, Ca2+, Mg2+, and,rarely, N or K+. The salts of these ions occur in highly variable concentraÂ tions and proportions. They may.
forage crops and grasses production and its annual growth in population, the deficit in all components of fodder, dry crop residues and feed has to be met from either increasing productivity. In irrigated areas, it is necessary to maintain an acceptable salt balance in the crop root zone, which requires some water for leaching. However, when irrigation efficiency is low and convey- ance seepage losses are high, the additional deep percolation losses are subject to the highly saline aquifers and soils common in the basin and result. PESTICIDE STUDY SERIES - 6 THE EFFECTS OF AGRICULTURAL PESTICIDES IN THE AQUATIC ENVIRONMENT, IRRIGATED CROPLANDS, SAN JOAQUIN VALLEY This study is the result of Contract No. awarded by the OWP, as part of the Pesticides Study (Section 5(2) (2) P.L. ) to the Food Protection and Toxicology Center, University of California at Davis.

Saline soils may adversely affect crop production just as do sodium soils. Saline soils have a conductivity of the saturation extract greater than 4 mmho per centimeter at 25° C. and an exchangeable-sodium percentage less than Large acreages of saline soils in the Southwest have been reclaimed by use of soil amendments and leaching : W.H. Fuller, D.F. Mcalister, D.S. Metcalfe. Adequate K also helps to improve stand persistence and winter survival. Sulfur (S) deficiency in alfalfa results in reduced yield, crude protein content, and feed value. It is most likely to occur in high rainfall areas, sandy soils, and under irrigation where the concentration of dissolved S in irriga- tion water is low.

I planted relatively long rows of three varieties (see below) and added various sources of calcium cross-row. I had one plot using lumber-mill “wet-ash” and another using “dry-ash” (both from the kilns at a mill) and one plot using calcium carbonate.
