Why fertilisers should be added to the soil immediately before and during the rainy seasons?

Fertilisers should be added to the soil immediately before and during the rainy seasons to enhance nutrient availability for crops when they are actively growing. Rainfall helps dissolve and distribute the nutrients in the soil, making them more accessible for plant uptake. Additionally, applying fertilisers at this time maximizes their effectiveness, as the moisture in the soil promotes nutrient absorption and minimizes nutrient loss through evaporation. This practice ultimately supports higher crop yields and healthier plants.
