SOIL CONSERVATION Made By: Samyak Jain - 04

SOIL CONSERVATION:

SOIL CONSERVATION Soil conservation is a set of management strategies for prevention of soil being eroded from the Earth’s surface or becoming chemically altered by overuse, acidification, salinization, soil erosion or other chemical soil contamination to retain the fertility of soil.

METHODS FOR SOIL CONSERVATION:

METHODS FOR SOIL CONSERVATION TERRACE FARMING: This method of farming uses "steps", called andenes , that are built into the side of a mountain or hill. On each anden , various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level. Additionally, these "steps" prevent a free flowing avalanche of water that would take plants with it and destroy the all of the crops on the hillside. This system also allowed them to build aqueducts, which carried water to each andenes Made By: Samyak Jain - 04

CONTOUR PLOUGHING:

CONTOUR PLOUGHING C ontour farming is the farming practice of ploughing across a slope following its elevation contour lines. The rows form slow water run-off during rainstorms to prevent soil erosion and allow the water time to settle into the soil. In contour ploughing, the ruts made by the plough run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level. Made By: Samyak Jain - 04

CROP ROTATION:

CROP ROTATION Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons. Crop rotation confers various benefits to the soil. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. Crop rotation also mitigates the build-up of pathogens and pests that often occurs when one species is continuously cropped, and can also improve soi structure and fertility by alternating deep-rooted and shallow-rooted plants.

SHELTER BELTS:

SHELTER BELTS Shelterbelt is a plantation usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted around the edges of fields on farms. If designed properly, windbreaks around a home can reduce the cost of heating and cooling and save energy. Windbreaks are also planted to help keep snow from drifting onto roadways and even yards. Other benefits include providing habitat for wildlife and in some regions the trees are harvested for wood products. Made By: Samyak Jain - 04

STRIP CROPPING :

STRIP CROPPING Strip cropping is a method of farming used when a slope is too steep or too long, or when other types of farming may not prevent soil erosion. Striely sown crops such as hay, wheat, or other small grains with strips of row crops, such as corn, soybeans, cotton, or sugar beets. Made By: Samyak Jain - 04

MULTIPLE CROPPING:

MULTIPLE CROPPING In agriculture, multiple cropping is the practice of growing two or more crops in the same space during a single growing season.  In which a second crop is planted after the first has been harvested, in which the second crop is started amidst the first crop before it has been harvested. A related practice, companion planting, is sometimes used in gardening and intensive cultivation of vegetables and fruits. Made By: Samyak Jain - 04
