organic fertilizers to lessen the country’s dependence on imported chemical fertilizers. Vermicast is produced when an earthworm excess its waste from the food they ate. Vermicast was used an organic fertilizer by the researchers by getting the NPK content. It is better than commercial fertilizers because it doesn’t contain chemicals that can make the crops destroyed. Earthworms can treat large amount of organic garbage‚ livestock manure and poultry droppings and turn them into premium organic fertilizers

decomposition. It also contains worms at various stages of development and other microorganisms associated with the composting processing. Earthworm castings in the home garden often contain 5 to 11 times more nitrogen‚ phosphorous‚ and potassium as the surrounding soil. Secretions in the intestinal tracts of earthworms‚ along with soil passing through the earthworms‚ make nutrients more concentrated and available for plant uptake‚ including micronutrients. Redworms in vermicompost act in a similar fashion

In terms of ecosystem goods and services‚ Victoria Park provides both material benefits and non-material benefits. The material value of the park mainly consists large amounts of trees‚ grass‚ bushes and small animals. Whereas the non-material values are mostly the recreational advantage and constant regulating services like air regulation. Chiefly‚ Victoria Park offers provisioning services. During my walk-through in Victoria Park‚ I was astounded by its vegetation coverage even in January. In

in this study are Amaranthus spinosus‚ Amaranthus caudatus and Amaranthus viridis L. They belong to the Amaranthaceae family and are traditionally used as vermicides. Our aim was to investigate the anthelmintic activity of the three plants using earthworms (Pheretima posthuma). Methanol extracts of the three plants at different concentrations (10‚ 20‚ 40‚ 60‚ 80‚ 100 mg/ml) showed dose-dependent vermicidal activities. At concentrations of 80 and 100 mg/ml all three plant extracts caused paralysis

crack. Factors which play important role in physical weathering include: * Erosion by wind and water. * The action of plants‚ for example‚ cracks caused by penetrating roots. * The action of animals‚ for example‚ worm casts formed by earthworms. * Human interference. Chemical Weathering is the breakdown of rocks using a solvent that is able to dissolve the mineral structure. Chemical weathering is due largely to the oxidation and reduction of the elements in the soil. Oxidized

Pile composting The animal waste and kitchen waste including some amount of leaves were mixed into the compost heap. Addition of daily generated waste was done in the same heap. Overturning of the compost pile was done in every 3 months for smooth decomposition. At the simplest level‚ the process of composting simply requires making a heap of wetted organic matter (leaves‚ "green" food waste‚ dung etc.) and waiting for the materials to break down into humus after a period of weeks or months.

Soil is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral
