Descriptif
The present study is therefore aimed at isolating and identifying the indigenous salt-tolerant strains of cyanobacterial species, occurring naturally in the salt-affected soils of Rohtak, Haryana with an objectives to utilize their salt-tolerant behaviour for growth in salt—affected soils and for evaluating their probable role in amelioration of these soils and improving crop production. Effect of algal i. zation was studied by using eight ’species of indigenous cyanobacteria isolated from salt-affected soils of Rohtak. and also by algal mixtures and their effects on soil, properties of four types of salt-affected soils were analyzed. The soil, properties studied included texture, water holding capacity, hydraulic conductivity, bulk density, cation exchange capacity, aggregation, pH, electrical, conduct i vity, organic carbon, available phosphorus, total nitrogen, ammonium nitrogen, nitrate nitrogen, calcium, magnesium, sodium, potassium and soil enzymes namely, dehydrogenase, urease and invertaae. Effect of algalization on growth performance of the two crops namely rice and wheat ware also studied in the present investigation using alternate cropping in pot culture.
