Composting and Plant Growth

Vermicomposting, as an industrial process, was originally developed to remove unwanted organic materials from the agricultural and industrial waste streams. The derived product: earthworm castings, is now recognized as a high value material which, when blended with soil, can restore soil tilth by correcting the imbalances caused by the over-utilization of petrol-chemical based fertilizers; thus enabling crops and plants to naturally combat pests and diseases, all resulting in increased crop production and general plant health. Using European technology we began researching production processes and the potential of Vermicomposting over 20 years ago. In 1991 we built the first American flow through Vermicomposting processor in Portland Oregon which continues to handle more than 2,000 tons of food waste per year at…

Different Types of Soils in India

1. Black soils The principal region of black soils is the Deccan plateau and its periphery extending from 8°45’to 26o north latitude and 68o to 83o45′ east longitude. They are formed from Deccan basalt trap rocks and occur in areas under the monsoon climate, mostly of semi-arid and sub-humid types. The overall climate of black soil region may be described as hot and dry summer, 40-100 cm rainfall per annum, mild to moderate winters and annual temperature ranges from 24-30o centigrade, mean maximum temperature during April-May ranges from 36~42°C arid mean minimum temperature during winter ranges from 15-24° centigrade. Semi-arid to sub-humid, tropical to sub-tropical monsoon type climate with alternate dry and wet periods and calcification (formation of calcium carbonate)…

What is soil erosion?

What are the negative impacts of soil erosion? Define overgrazing, overcultivation, and deforestation. Include ideas on what people can do differently to reduce the impact of these three practices on soil erosion. Provide examples of where this happens both locally and regionally. Within the examples list the specific consequences. Soil is naturally removed by the action of water or wind: such ‘background’ (or ‘geological’) soil erosion has been occurring for some 450 million years, since the first land plants formed the first soil. In general, background erosion removes soil at roughly the same rate as soil is formed. But ‘accelerated’ soil erosion – loss of soil at a much faster rate than it is formed – is a far more…

An essay on drought

Others, such as the drought of 1982±83, can affectmore than half of the country. Droughts can beshort and intense, such as the drought that lastedfrom 1 April 1982 to 28 February 1983; or they canbe long lived, such as the drought from 1 March1991 to 31 December 1995. When drought comes to Australia, agriculturesuffers first and most severely Ð and eventuallyeveryone feels the impact. Economic impactsDrought affects farmers through a decline in, ora loss of, the production of crops and livestock. This in turn affects the level of economic activityin rural towns and even large cities. The droughtof 1963±68 affected large parts of the continentand was the longest drought ever in arid centralAustralia. The last two years of this drought…

Investigatory Project

Soil is a complex mixture of inorganic materials with variable amounts of air and water. The inorganic materials includes clay, silt, sand, gravel and rocks. Soil is a variable mixture of minerals, inorganic matter, and water, making it capable of supporting plant life. But as the time passes by, problems arise in relevance to soil utilization such as erosion, floods, landslides and earthquake. So, the study of soil has been done by the land use planners to evaluate natural hazards and the soil capability through waste management, appropriateness for agriculture, wildlife, and for infrastructure. In India, Soil Erosion is among the leading areas of concern of the government. It affects cultivation and farming in the country in adverse and unfavorable…
