In: “Methodology for Biomass Determinations and Microbial Activities in Sediments” (eds. The functional diversity of the soil microflora was assessed based on microbial processes (N mineralization, ammonium oxidation, arginine deaminase) as well as on the activities of soil enzymes (protease, urease, xylanase, phosphatase, arylsulphatase). Soil taxonomy is similar to plant and animal classification in that the system is based on INTRODUCTION The problem of environmental contamination by pesticides goes beyond the locality where it is used. Plant height was calculated starting from stem base to the tip of the tallest leaf, and their dry biomass was calculated [15]. Root growth seemed to be more affected by high IAA producers in unsterile soil and maximum vigour index of 32600 was exhibited by BA2(D)1 which is a medium IAA producer and the minimum of 15750 was by BA1(E)2 which is a high IAA producer. Sambrook, J., Fritsch, E.

The amount of all tested -product compost. ciceri. This service is more advanced with JavaScript available, Techniques in Mycorrhizal Studies Vol. Soil microbiological applications in agriculture have often been neglected in temperate zone countries in favor of chemical fertilizers. Hence IAA producers of the fluorescent Pseudomonas group showed significant plant growth when compared with control but plant growth was not greatly influenced by those organisms that produced high amounts of IAA. Soil microorganisms are classified, fertilizers could affect the quantity and quality of microbial, higher number of bacteria in the rhizosphere tha.
