The present investigation entitled “
Effect of Long term Fertilization on Biological Properties of Soil under Soybean -Safflower Cropping Sequence in Vertisols”. A field experiment carried out during 2021-22 at Long Term Fertilizer Experiment Research Farm, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was carried out in Randomized Block Design (RBD) with 12 treatments replicated four times.
Population
of bacteria, fungi and actinomycetes were varies from 30.26 to 58.51 CFU × 10
