Ammonium sulphate is a common fertilizer used in paddy fields to provide essential nutrients like nitrogen and sulphur to the growing rice plants. Proper application of this fertilizer is crucial to ensure optimal growth and yield of paddy crops.
The best time to apply ammonium sulphate in a paddy field is during the early stages of the rice plant’s growth. Typically, the fertilizer is applied just before planting the rice seeds or shortly after the seedlings have emerged. This timing allows the nutrients to be readily available to the young plants as they establish their root systems and begin to grow.
When applying ammonium sulphate, it is important to ensure that the fertilizer is spread evenly throughout the field. This can be achieved by using a spreader or by broadcasting the fertilizer by hand. Care should also be taken to avoid applying the fertilizer too close to the rice plants to prevent burning the roots.
The amount of ammonium sulphate to apply will depend on the soil’s nutrient levels and the rice variety being grown. A soil test can help determine the appropriate application rate for optimal growth. Typically, around 50-100 kg of ammonium sulphate per hectare is recommended for paddy fields.
It is also essential to consider the timing of subsequent applications of ammonium sulphate throughout the growing season. Additional fertilizer may be needed during the tillering and heading stages of rice growth to support healthy plant development and maximize yield potential.
Overall, proper timing of ammonium sulphate application in a paddy field is essential for promoting healthy rice plant growth and maximizing crop yield. By following recommended guidelines and monitoring nutrient levels throughout the growing season, farmers can ensure their paddy fields are well-nourished and produce a bountiful harvest.
