As a farmer, it is essential to have a clear understanding of the fertilizers that can be used in the crops and the amount of dosage required. With the non-availability of DAP as a fertilizer for wheat crops, farmers can use superphosphate as an option.
Superphosphate is a fertilizer that contains easily digestible nutrients of phosphorous, sulfur, and calcium in abundance, which are essential for the growth of the wheat crop. The application of superphosphate promotes root growth, boosts natural resistance to diseases, and facilitates the growth of the wheat crop, leading to high yield.
When it comes to the dosage of superphosphate, it depends mainly on the soil test. However, in most cases, a recommended dose of 40-60 kg per hectare or 35-55 lb per acre for winter cereals such as wheat, barley, and rye is suggested. The application of superphosphate should be even and should be broadcast evenly over the soil.
Apart from the dosage, the timing of the application of superphosphate is also crucial. It is generally best to apply superphosphate during the early stages of planting, preferably before planting or at the time of planting. This application will ensure that the nutrients are available during the wheat crop’s critical growth stages.
It is also essential to note that superphosphate should not be used alone and must be blended with nitrogen and potassium fertilizers to give the desired nutrition to the wheat crop. An essential point to remember is that the excess application of superphosphate can lead to a build-up of the nutrient in the soil, which can lead to toxicity.
In conclusion, the dose of superphosphate required for the wheat crop depends on the soil test and is usually around 40-60 kg per hectare or 35-55 lb per acre. Farmers should ensure that the superphosphate is applied evenly and at an optimum time for the best results. The use of superphosphate in combination with nitrogen and potassium fertilizers can lead to the desired nutrition for the wheat crop, and excess accumulation of superphosphate can be toxic for the soil.
