OBJECTIVE FORESTRY

Detailed explanation-1: -Nutrients which are required in large quantities are called as macronutrients. Primary (macro) nutrients are nitrogen, phosphorus and potassium. They are the most frequently required in a crop fertilization program. Also, they are need in the greatest total quantity by plants as fertilizer.

Detailed explanation-2: -Macronutrients are essential for plant growth and a good overall state of the plant. The primary macronutrients are Nitrogen (N), Phosphorus (P), and Potassium (K). Nitrogen is essential for plant development, since it plays a fundamental role in energy metabolism and protein synthesis.

Detailed explanation-3: -Macronutrients, or “macros, ‘’ are nutrients your body needs in large amounts to function optimally. Carbs, protein, and fat are the three main macros.

Detailed explanation-4: -Macronutrients are required in large quantities while micronutrients are required in trace or very small amounts. In plants, the macronutrients are nitrogen, phosphorus and potassium (NPK) while the micronutrients include boron, iron, manganese, etc.

Detailed explanation-5: -Macro elements include chloride, calcium, phosphorous, magnesium, sodium, potassium, and iron. The trace elements include cobalt, boron, chromium, copper, sulfur, iodine, fluoride, selenium, manganese, zinc, and molybdenum (Figure 1). Classification of different nutrients need in metabolism.
