Drland crops yield may be increased by maintaining soil biological properties
Dr. Pawar, for dryland crops you have to estimate microbial population, microbial biomass C & N, individual beneficial microbes such as Azotobacter, Azospirillum, Rhizobium, Phosphorus solubilizers, Phosphatase and phytase producing organisms, AM fungi population, beneficial soil enzymes like dehydrogenase, esterase, phosphatases, phytase, urease, aryl sulphatase, cellulase, hemicellulase and lignase, decomposers like cellulose, hemicellulose, lignin, organic matter content and earthworm population,
Thank you for you valuable answer sir. I tried Bacterial count fungi N fixer and p solubilizer actinomycetes etc till now. Definately go as per your advice.
Soil microbial count and volume is more important as soil moisture stress is concerned
yes. bt in moisture stress condition how much soil micro flora remain alive that is also most important factor.
The soil microbiological parameters shoould be analysed, measured . SMBC: it expresses the total amount of microbial in soil, mainly bacteria and fungi, measured as the ATP (adenosine triphosphate) content.
(ii)SOM mineralization (SOMM): this quantity is the sum of CO2 production during the 15 days of incubation, expressed on an organic matter basis.(iii)CO2 production-to-ATP ratio, or specific activity of the microbial biomass. This ratio is similar to the more generally used metabolic quotient (qCO2), which has been repeatedly used as a stress indicator , is related to the disponibility of nutrients, especially organic carbon, and it is often used as an indicator for assessing the influence of the environment conditions on soil microbial communities.
Dr. Singh, under dry-land conditions actinomycetes/actinobacteria is the most dominant microorganisms. So, in that harsh conditions one must estimate actinomycetes population also beside fungi and bacteria. One can also get an idea of nematode count. beside this lipase-esterase activity also important.
