Salinity in ground water and ...

Salinity in ground water and sodic land may perhaps be caused by complex set of factors.I believe that monoculture and excessive water use in irrigation contribute to salinization of agricultural lands.Biodiversity helps to disperse and helps bioconversion of salts left over from the TDS in water.Biodiversity in plants in a given micro environment helps in better assimilation and use of salts.This may be a plot of land or a whole village or taluk, zilla or district in rural places. Weeds are beneficial and should not be removed totally but allowed to grow, then cut or slashed and the biomass should be mulched into the top soil. Two solutions developed in India: Dr Uday Bhawalkar offers explanations which defy conventional academic approach to such problems.He has developed and also improved the performance of biocatalysts over the years, which he calls as Biosanitizer. He also advocates use or organic materials like sewage mixed with sea water and treated with Biosanitizer for use as irrigation water.Fodder grass has thus been grown on sodic lands. Brackish water can be treated by dropping the Biosanitizer into wells or tubewells containing brackish water.The TDS is not lowered but salts are now usable by plants as food due to a bio-convertion process, which conventional chemistry does not explain properly or ignores.His web site: www.wastetohealth.com Similarly another scientist named Swami Valmiki Sreenivasa Ayyangarya has developed Guruvani, whose functions are similar to Biosanitizer.It has proved itself in arresting algal bloom in very large water bodies.He uses Vedas and sciences not known today but were in use in ancient India.He can successfully treat highly toxic industrial effluents and use them for agriculture. He does not have a web site.
