Resources and Development Test - 12

Laterite has been derived from the Latin word ‘later’ which means brick. The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. Humus content of the soil is low because most of the micro organisms, particularly the decomposers, like bacteria, get destroyed due to high temperature. Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers. These soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Odisha and Assam. 

Developed resources are the resources which are surveyed and their quality and quantity have been determined for utilisation. The development of resources depends on technology and level of their feasibility. 

1: Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. Examples of non renewable resources are coal, crude oil etc. Examples of renewable resources are air, water, natural gas, wind, solar energy, etc.
2:The resources which can be renewed or reproduced by physical, chemical or mechanical processes are known as renewable or replenishable resources. For example, solar and wind energy, water, forests and wildlife, etc. 

3: Non-renewable resources occur over a very long geological time. Minerals and fossil fuels are examples of such resources. These resources take millions of years in their formation. Some of the resources like metals are recyclable and some like fossil fuels cannot be recycled and get exhausted with their use

 Resources that are found everywhere like the air we breathe, are ubiquitous. 

The organic fertilizers are used to improve the fertility of alluvial soil. This type of fertilizer originates from an organic source. Some examples include fish extracts, manure, and compost. 

Barren land- An area of land not suited for cultivation.

Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated. 

The black soil is also known as Regur soil. Black soil is ideal for growing cotton. 

This is the most widely spread and important type of soil. In fact, the entire Northern Plains are made of alluvial soil. The alluvial soil consists of various proportions of sand, silt and clay. Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime.

The Laterite Soil is the type of soil formed from intense leaching in areas of high rainfall , moisture and high temperature. The soil formed by the process of intense leaching is laterite soil.
