❓ Frequently Asked Questions

What is NPK in fertilizer?

NPK stands for Nitrogen (N), Phosphorus (P), and Potassium (K) — the three primary macronutrients in fertilizer. Nitrogen promotes leafy growth, Phosphorus supports root and flower development, and Potassium improves overall plant health and disease resistance.

What is Urea and how much N does it contain?

Urea (CO(NH2)2) is the most widely used nitrogenous fertilizer in India. It contains 46% Nitrogen by weight. So to supply 46 kg of N, you need 100 kg of Urea. It is the cheapest source of nitrogen.

What is DAP fertilizer?

DAP (Di-Ammonium Phosphate) is a common fertilizer containing 18% Nitrogen and 46% P2O5 (phosphorus pentoxide). It is used as a basal dose at the time of sowing to supply both nitrogen and phosphorus.

What is MOP fertilizer?

MOP (Muriate of Potash) or KCl contains 60% K2O (potash). It is the primary source of potassium for crops. MOP improves crop quality, enhances drought resistance, and helps in disease prevention.

What does split dose application mean?

Split dose application means dividing the total fertilizer dose into multiple applications. The standard recommendation is: 50% as basal dose at sowing, 25% at tillering/vegetative stage, and 25% at flowering/reproductive stage. This improves nutrient use efficiency and reduces losses.
