Complete Fertilizer Guide for Paddy Cultivation in Sri Lanka (Yala & Maha)

Paddy cultivation remains the lifeblood of Sri Lankan agriculture. Maximizing yields during both the Maha (northeast monsoon) and Yala (southwest monsoon) seasons requires a balanced nutrient management approach. ### 1. Basal Application (Before Final Leveling) Before transplanting or sowing pre-germinated paddy seeds, replenish soil minerals with high quality bio-compost and basal phosphate. Incorporating BioRich Organic Compost improves soil cation exchange capacity (CEC), allowing chemical fertilizers applied later to bind effectively rather than leaching away with irrigation water. ### 2. First Top Dressing (14–21 Days After Sowing) Nitrogen is crucial for vigorous tillering. Apply Aggro Urea (46% N) at recommended regional rates. Avoid applying nitrogen on waterlogged soils without controlling drainage. ### 3. Panicle Initiation Stage At this critical juncture, apply Aggro MOP (Muriate of Potash 60%) alongside remaining Urea. Potassium strengthens the rice stem against lodging during heavy rain and guarantees full grain filling without empty chaff.
