Description

Only once the nutrient supply is so low that the plants can no longer function normally do nutrient deficiency symptoms manifest. When this happens, fertiliser should have been used long before any symptoms showed up. Early detection of the symptoms may allow for treatment to take place throughout the growing season. Since one of the goals is to get the limiting nutrient into the plant as quickly as possible, foliar sprays or side dressings may be used with some nutrients and in some situations to achieve this goal. Usually, the yield is lower than what would have been obtained if sufficient nutrients had been present at the start. The goods that the grower is interested in are the developing plants, which integrate all development variables. Therefore, a thorough examination of the developing plant can assist in locating a particular nutrient stress. Typical signs may show up if a plant is deficient in a specific nutrient. A nutritional deficiency does not immediately result in symptoms. The current book explains how to spot deficiencies in the various mineral plant nutrients in widely cultivated agricultural and horticulture crops.
