Waste land Reclamation

 Waste land : 

The land  which is not in use is called waste land. The waste land is unproductive, unfit for cultivation, grazing and other economic uses. About 20% of the geographical area of  India is waste land. 


Type Of  Waste land : 

Waste lands can be divided into two types 

1.Uncultivable waste lands

2.Cultivable waste lands 

1. Uncultivable waste lands : These lands cannot be brought under cultivation. 

Examples - Barren rocky areas, hilly slopes, stony  or leached  or gully land (or) sandy deserts, etc.,

2. Cultivable Lands : These are cultivable but not cultivated for more than five years. Cultivable waste lands are important for agricultural purposes. 



Examples - Degraded forest lands, gullied lands, water logged and  marsh lands, saline lands, etc., 

Causes of  Waste land  formation :

1. Due to soil erosion, deforestation, overgrazing, water logging, salinity.

2. The increasing demand for fire-wood and excessive use of pesticides.

3. Developmental activities like construction of dams and power projects have caused considerable damage to land due to water logging. 

4. Over-exploitation of natural resources. 

5.  By the Sewage and Industrial wastes. 

6.  Mining Activities destroy the forest and cultivable land.

ELECTRICAL COMPARATORS AND ITS WORKING

Electrical Comparators are used as a means of  detecting and amplifying small movements of a work contacting elements. An electrical comparator consists essentially of  a pick-up head or transducer for converting a displacement into a corresponding change in current and a meter or recorder connected in the circuit to indicate the electrical change, calibrated to show in terms of displacement. Generally, an amplifier is needed to provide the requisite sensitivity and to match the characteristics of different parts of  the circuit. Electrical comparators can be classified according to the electrical principle used in the pick-up head. Most of the comparators use either a differential transformer, an inductance bridge, a strain gauge or a capacitor as a means of detecting movement of the gauging element. There are different types of  electrical comparators. One kind called an electrolimit gauge is used to check or measure the outside diameter of a  roll. The objec...

SIMPLE CARBURETOR - CONSTRUCTION AND WORKING

CONSTRUCTION OF SIMPLE CARBURETOR :  The main Components of Simple Carburetor are : Float Chamber, float, nozzle, venturi, throttle valve, inlet valve, and metering jet . In the float chamber, a constant level of petrol is maintained by the float and a needle valve.  The float chamber is ventilated to atmosphere.  This is used to maintain atmospheric pressure inside the chamber. The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases to certain level. The mixing chamber contains venturi, nozzle and throttle valve. The venturi tube is fitted with the inlet  manifold. This tube has a narrow opening called venturi. A nozzle is provided just below the centre of this venturi. The nozzle keeps the same level of petrol as that of the level in the float chamber. The mixing chamber has two butterfly valves.  One is to allow air into the mixing chamber known as choke valve. The other is to al...

TOP POLLUTION RECORDED IN WORLD

CHERNOBYL NUCLEAR DISASTER (NUCLEAR POLLUTION) :  In April 26,1986, the melt down of the Chernobyl nuclear reactor , in Russia, has leaked out the radioactive rays and radioactive materials.   Effects : 1. In this Pollution nearly 2000 persons have been killed by the accident. 2. People suffered due to the illness such as, degeneration of the cells, severe bleeding, anemia, skin cancer. 3. Animals, Plants are also affected by nuclear radiation.  MINAMATA EPIDEMIC (1953) : MARINE POLLUTION ( CASE STUDY ) Minamata is a small coastal village in Japan. The Chisso Chemical Company , which produces vinyl polymer plastics used organomercurial compound. The industry released its effluent into Minamata sea. The effluent containing mercury ions is converted into methyl mercury, which is highly toxic.  The marine organisms like phytoplankton and zoo-planktons easily absorb the toxic methyl mercury compound. These organisms are consumed by small fishes and these are in ...
