The experiment was completed in three stages. Representative samples of water cabbage (Limnocharis flava), coir pith, water hyacinth (Eichhornia crassipes) and farm wastes (dried leaves and pseudostem of banana) were collected and analysed for bio-chemical composition. Then the four substrates were treated with four inoculants viz., Trichoderma reesei, Pleurotus sajor-caju, composting inoculums and commercial enzyme cocktail. The resultant composts were analyzed for the manurial value so as these weed plants and farm residues can be efficiently utilized for the preparation of composts which can induce the soil nutrient content and health. From the study water cabbage was the best substrate in terms of their chemical composition followed by water hyacinth.Keywords

Kuttanad, the rice bowl of Kerala is a unique agricultural tract lying 0.6 to 2.2 m below MSL. The soils of the area are highly acidic, saline and high in organic carbon content. Several parts of this delta have subsoil layers containing pyrites which on oxidation produce severe acidity. Hence, the present study was envisaged to characterize the acid sulphate wet land soils of Kuttanad. For the collection of soil samples, stratified random sampling technique was followed. Surface (0-15 cm) and sub surface (15-30 cm) soil samples were collected from the identified six soil series viz., Ambalapuzha, Kallara, Purakkad, Thakazhi, Vaikom and Thuravoor. From the study it is inferred that the pH of the samples varied between 3.0 -4.0 which is typical for acid sulphate soils. Lab incubation studies also revealed that there was a drastic decline in the pH of the soil with submergence while the EC ranged between 0.1 - 8 dS/m. With regard to the enzyme assay between the locations, subsurface soil samples collected from the wetlands of Thuravoor reported to have the highest value of 76.1 ppm of urea hydrolysed g-1 of soil hr-1 for urease and surface samples of Thakazhi had the highest of 105.8 μg of p-nitrophenol released g-1 of soil hr-1 for phosphatase. In the case of respiratory activity, which is an indicator of soil microbial biomass, surface samples from Thuravoor recorded the highest followed by Vaikom.Keywords

A pot culture experiment was carried out in the Department of Soil Science and Agricultural Chemistry, College of Agriculture, Vellayani during 2000 to study the effect of xenobiotics (agrochemicals ) on enzyme activities. The enzymes selected were urease, phosphates, protease, dehydrogenase and cellulase. Thirteen chemicals viz., phorate, carbofuran, quinalphos, monocrotophos, chlorpyriphos, hinosan, bavistin, streptocyline, benthiocarb,2,4–D, butachlor, oxyflourfen were used for the study which can be categorized as insecticide, fungicide, antibiotic and herbicide. The experiment was carried out using rice (var. Kanchana) as a test crop. The results revealed that the antibiotics impart maximum inhibition on the enzyme activities followed by fungicides, insecticides and herbicides.Keywords
