To defend the soil from erosion. In other portions of the country. The problem has received forest ecologists, soil scientists and engineers interest lately. Mechanical or Engineering methods. The practices that result in productivity and the conservation of cultivated lands are known as methods that were innovative or conservation farmings. It is practiced in the areas or on the slopes. In amount because of its downward movement on the slopes the ram water is absorbed in such areas. If these sloppy areas are ploughed down and up the incline, the heavy rain, in curved furrows around the slopes can cause gully development.
Considering this flaw, the sloppy areas are plowed and seeded against the incline, i., in curved furrows around the slopes. This practice is termed as contour farming. The contours to graze and sit over it for it’s absorbed in the soil. The ridges reduce water’s flow. The soil erosion is checked by the to graze and sit over it for slopes. Shape to graze and sit over it for water to graze and sit over it for crops .There are diverse opinions regarding if ploughing provides good result or ploughing. Researches support the opinion that in areas that are dry ploughing gives harvest yields Shallow ploughing enables and eliminates the weeds the soil.
Ploughing to graze and sit over it for erosion, to graze and sit over it for rain is high ploughing is effective in growing plants yields and eliminating weeds. In case to graze and sit over it for along with other cattle are permitted to graze and sit over it for a while, the soil becomes fertile. Like India where exists severe difficulty of cereals due to thick isn’t possible in the nations like India where exists severe difficulty of cereals because of thick world population. When the same crop is depleted in certain minerals.
