Abstract:

An experiment was carried out under long term trial in randomized block design (RBD) at Indira Gandhi Krishi Vishwavidyalaya, Raipur, India to comprehend the long-term effect of fertilization and algalization on soil aggregation; C and N fractions associated with such aggregates under rice based cropping sequence. Three treatments viz. control, 50% NPK and NPK + BGA (blue green algae)were studied and results revealed that the treatments amended with 50% NPK and 50% NPK + BGA significantly enhanced soil aggregate stability and C as well as N associated with aggregates at upper and lower profile depths over control. The present experiment suggested that inappropriate nutrient management strategy under unremitting cereal- cereal (rice-wheat) cropping system resulted poor aggregate stability, lower C and N content in aggregates, whereas; the addition of suboptimal dose of NPK with or without blue green algae (BGA) gave rise to increase such properties over no fertilization.
