Detailed explanation-1: -Black soil is suitable for dry farming because it is fine-grained, rich in calcium and it can retain moisture to a large level and is sticky in nature. It has a higher water holding capacity. Some of the major crops grown on the black soils are cotton, wheat, linseed, Virginia tobacco, castor, sunflower, and millets.
Detailed explanation-2: -Black soil has more moisture and organic content. It is very retentive of moisture. It swells greatly and becomes sticky when wet in the rainy season.
Detailed explanation-3: -Clay soils, while typically regarded as sloggy and undesirable for conventional agriculture, are actually ideal for dry-farming! Why is that? Clay absorbs and retains moisture for much longer than sand or loam type soils. A clay-loam is an ideal balance of nutrition, organic matter, and the right absorbency.
Detailed explanation-4: -Final answer: Black soils are best suited for the cultivation of Cotton.
Detailed explanation-5: -Answer: Because of their high clay content, the black soil has wide crack during summers but they are resistant to wind and water erosion. They are highly moisture-retentive. This retention of moisture makes sure that the crop gets water for a long time without irrigation or rains.
