Detailed explanation-1: -Plants that are deficient in nitrogen have stunted growth, depending on the severity of the deficiency. Leaf growth is inhibited; younger leaves are inhibited in particular. Longitudinal shoot growth is inhibited, as is the increase in thickness.
Detailed explanation-2: -Excessive irrigation and heavy rains cause nitrogen deficiency due to overwatering. A lack of soil moisture tampers with the absorption of water-soluble nutrients by plant roots.
Detailed explanation-3: -Nitrate deficiency Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant’s ability to photosynthesise and grow properly, which reduces the farmers’ crop yield .
Detailed explanation-4: -Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. This is known as “robbing” the soil of nitrogen.
