Acephate, dimethoate and phosphamidon are organophosphate pesticides with high toxicity and may significantly affect soil microbial activities. However, the magnitude of this effect is unclear yet. The potential harmful effect of these pesticides on soil enzyme activity was accessed in the soil collected under controlled laboratory conditions. We examined the effect of recommended (RD) and double the recommended doses (2RD) of these pesticides on the soil enzymatic activities. The incubation study was carried out at 60% of maximum water holding capacity of the soil sample at 28±2°C for a period of 42 days. Our results indicated that high acephate, dimethoate and phosphamidon doses significantly affect enzymatic activities in the soil. Our results provide the first evidence that acephate, dimethoate and phosphamidon differentially affected the soil microbial community through inhibiting fungal and bacterial populations.Keywords

Sorption isotherms have been widely used to assess the heavy metals retention characteristics of soil particles. Adsorption behaviour of cadmium (Cd) in soils is an important process which exerts a major influence on its uptake by plant ischolar_mains. Desorption behaviour of the retained metals, however, usually differ from that of adsorption, leading to a lack of coincidence in the experimentally obtained adsorption and desorption isotherms. Three soils differing in physico-chemical properties (pH 5.7 to 8.2) and varied taxonomy (Typic Ustochrepts, Typic Rhodustalfs and Entic Chromusterts), were subjected to Cd treatment at various concentrations (0, 2, 4, 8, 15, 30, 45, 75 mg Cd/L). The Cd adsorbed by each soil was calculated as the difference between the amount of Cd present in the solution initially and that remaining after equilibration. Immediately after adsorption, desorption took place using successive dilution method with five consecutive desorption steps. Both, Cd adsorption and desorption data were described by Freundlich equation. The adsorption and desorption reactions, however, did not provide the same isotherms, indicating that hysteresis occurred in Cd adsorption-desorption process. Results indicated that the adsorption capacity of the soils for Cd increased with an increase in the pH or alkalinity of the soils. The rate of adsorption was, however, found to decrease with increased pH. But no specific trend was observed in case of desorption. All the three soils used in this study followed Freundlich adsorption isotherms. The adsorption data, in general, indicated that Cd was in a fixed form at higher pH levels. The Cd adsorption was in the order of Entic Chromusterts > Typic Ustochrepts > Typic Rhodustalfs.Keywords

Heavy metals are potentially toxic to human life and the environment. In a greenhouse pot experiment, Typic Ustochrepts soil order (alluvial soil) with pH 5.7 was used. African marigold variety Pusa Narangi was used as a test crop. The soil was artificially spiked with different cadmium (Cd) levels (0, 5, 10, 25, 50 and 100 mg kg-1). Critical toxic concentrations of Cd resulting in 25 per cent reduction in dry matter yield were established for African marigold grown in alluvial soil. The corresponding values for non-inoculated, arbuscular mycorrhiza (Glomus moseae) and phosphorus solubilizing fungi (Aspergillus awamori) treated soils, respectively, were 28, 24 and 16 mg kg-1 Cd applied in soil; 12, 12 and 8 mg kg-1 AB-DTPA extractable Cd in soil; 6.4, 6.2 and 6 mg kg-1 Cd content in plant tissues.Keywords

Rapid urbanization, industrialization and agricultural intensification are accompanied with generation of huge amounts of rural and urban wastes. The estimated annual production of agricultural byproducts/wastes of field crops, fruits and vegetable crops waste are 679, 83.34 and 173 Mt, respectively out of which surplus available for processing are estimated at 233, 41.67 and 86.50 Mt. Annually, most of the metropolitan cities of India are generating about 64.8 million tonnes of city refuse during the year 2010 with a potential of 9.1 million tonnes of compost per annum. Present study have been carried out to evolve efficient ways to ensure improvement in available nutrient status of composts through microbial enriched compost. The objective of the study was to accelerate the decomposition process, improvement of nutritional quality and minimize the heavy metals in end product. To evolve efficient ways cellulolytic organisms viz., Aspergillus heteromorphus, Aspergillus terrus, Aspergillus flavus and Rhizomucor pusillus along with mineral nitrogen was used to accelerate the process of decomposition and its maturity indices and the manurial value was compared with existing farmers practices. Results showed that the microbial enriched compost proved better to produce higher quality manure, shorten the usual period of composting from 6 months to 2.5 months.Keywords

In the recent past, yield stagnation in major cropping systems of India along with declined soil fertility and soil health have emerged as a prime threat to sustainable food security. Moreover, with the rising population, there is increase in food demand from the limited land resources. This situation has led to a huge gap between the availability of nutrients and demands to sustain food security. It has thus become the need of the hour to recover and recycle nutrients that have been mined from the soil. Hence, recycling of surplus crop and horticultural residues, and animal excreta seems to be a viable option to minimize the nutrient gap. However, cumulative estimated data on the availability of unutilized crop and horticultural residues, and animal excreta are scare in Indian context. The present article gives an estimate of recyclable biowaste in the states of central and western India, that could be utilized as baseline information by future policymakers.Keywords
