INDIAN GEOGRAPHY

Detailed explanation-1: -Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element.

Detailed explanation-2: -These three numbers form what is called the fertilizer’s N-P-K ratio-the proportion of three plant nutrients in order: nitrogen (N), phosphorus (P) and potassium (K).

Detailed explanation-3: -The NPK ratio found on fertilizers, such as 15:15:15 or 5:20:20, indicates the percentage of these nutrients inside the fertilizer. 5:15:5 would indicate a phosphorus fertilizer. Different NPK ratios serve different types of plants and support different developmental processes.

Detailed explanation-4: -The P in NPK is phosphorus Phosphorus stimulates root growth, helps plants set buds and flowers, and produce seeds. It also helps plants use other nutrients more efficiently, and helps turn energy from the sun into usable energy for your plants.

Detailed explanation-5: -NPK refers to the three nutrients that constitute complete fertilizers: nitrogen, phosphorus, and potassium.
