Ten typical pedons in Malwa Plateau region of Banswara district in Rajasthan were studied for vertical distribution of DTPA-extractable iron, manganese, zinc and copper and their relationship with some soil properties. Soil reaction, calcium carbonate, organic carbon and particle size fractions had strong influence on the distribution pattern of these micronutrients in the profile. The contents of available iron, manganese, zinc and copper were higher in surface horizons and decreased with depth in most of the pedons and ranged from 6.34 to 54.71, 2.42 to 57.64, 1.01 to 5.10 and 1.20 to 6.10 mg kg-1, respectively. All soils had adequate amounts of iron, manganese, zinc and copper. The available micronutrient content in these soils were in the order of Fe>Mn>Cu>Zn. DTPA extractable Fe gave significantly and negative correlation with pH, CaCO3, clay and CEC while significantly and positive correlation gave with organic carbon. Mn gave negative significant correlation with CaCO3 and clay. Zn gave negative significant correlation with clay while Cu was positively significantly correlated with silt.Keywords

An enrichment study on vermicomposting of nutrient supplemented and microbially inoculated mixture of mustard crop residue and farm weeds with fresh cattle dung using Eisenia foetida was conducted in pits. Mixture of composting material was supplemented with 0.5 per cent urea, 1.0 per cent beneficiated rock phosphate, 0.15 per cent of ferrous and zinc sulphate and inoculated with lignocellulolytic microorganisms (Trichoderma viride, Cellulomonase fimi and Bacillus sp.), Azotobacter chroococcum, Bacillus megaterium and 500 adult earthworms pit-1 were released according to treatments making seven combinations. During vermicomposting, composting mixtures were analysed for cellulase activity and microbial populations. At harvest, fresh vermicompost yield, earthworm density, C : N ratio, nutrient contents and humus fractions were recorded. Results revealed that combination of both nutrient supplementation and microbial inoculation positively influenced in increasing the macro and micro nutrient content, humus fractions, earthworm density and quality of vermicompost in respect of lower C : N ratio and less fresh vermicompost yield. Cellulase activity and microbial (bacteria, fungi and actinomycetes) populations were higher in enriched vermicomposting pit than control during the process of decomposition.Keywords
