Fertilizing paddy fields is essential to achieve a bumper harvest. However, knowing when to apply the fertilizers is crucial. Applying fertilizers at the right time will ensure healthy growth, increased yield and reduced wastage. Here are some tips for when to apply fertilizers in paddy fields.
Pre-planting Fertilization:
Before planting, farmers should fertilize their paddy fields with organic compost or manure. This improves soil fertility, aiding in the growth and development of the seedlings. Mixing the organic compost with the soil helps to break down the compost fast, releasing the required nutrients for plant growth.
Early Stage Fertilization:
After planting the seedlings in the paddy fields, farmers should apply fertilizers when the seedlings reach the three-leaf stage. The nitrogen level should be high enough to support seedling establishment. Fertilizers that are high in phosphorus should be used as they promote the growth of the roots and helps plants withstand stress and environmental changes.
Mid-Stage Fertilization:
During the mid-stage, applying fertilizers is critical for optimal yield. At this stage, the rice plants require more nitrogen for healthy vegetative growth. Farmers should use fertilizers that have a higher content of nitrogen, such as Urea, ammonium sulfate or ammonium nitrate. Nitrogen fertilizers promote leaf growth and help plants overcome any negative effects from the environment.
Late-Stage Fertilization:
At the late stage of the plant growth cycle, fertilizers that are high in potassium, such as muriate of potash, are used. Potassium fertilizers allow for the build-up of starch in the grain and promote plant quality and health. These fertilizers can also contribute to increased rice grain yields.
In conclusion, applying fertilizers at the right time is critical to the success of a paddy farmer. Through pre-planting, early, mid and late-stage fertilization, farmers can ensure that their rice plants receive the necessary nutrients at the right time for optimal growth and resultantly a bumper harvest. Applying the right type of fertilizers at the right development stage ensures that the full potential of the plants is realized, and wastage is minimized.
