As one of the most widely cultivated and consumed cereal grains, wheat is an important crop across the world. In its cultivation, proper soil health and fertilization practices are key to ensuring robust yields and good quality grain. One element of wheat fertilization is applying fertilizer at the time of sowing. Here is some information on the fertilizer dose at the time of sowing of wheat.
Before diving into fertilization specifics, it’s important to note that for optimal growth, wheat requires a fertile and nutrient-rich soil. As such, farmers should first conduct soil tests to determine the nutrient content and pH level of their soil. This information can guide appropriate fertilization measures, including the fertilizer dose.
Typically, the optimal time to apply fertilizers for wheat is at the time of sowing. This applies to both traditional tilling and no-till farming methods. There are different types of fertilizers available, including organic and inorganic compounds, but the most commonly used for wheat are nitrogen, phosphorus, and potassium.
For wheat, the recommended fertilizer dose varies depending on factors such as cropping intensity, soil type, and rainfall. In general, it is suggested that a dose of 120 kg per hectare of urea is applied at the time of sowing. Phosphate fertilizers, such as superphosphate, can also be used at the time of sowing at a rate of 60 kg per hectare. If soil tests show potassium levels to be low, potassium fertilizers can be added at seeding. However, it’s important not to over-fertilize, as this can lead to negative impacts such as water and air pollution, soil acidification, and wastage of nutrients.
Along with the dose, proper placement of fertilizer is important as well. The fertilizer should be placed 2-3 inches below the seed or sowing depth to limit salt injury on the seedlings. As wheat sowing is usually done through furrow openers, a special attachment called a hoe opener can also be used for applying fertilizers just below the seed in the furrow.
In conclusion, applying fertilizer at the time of sowing is essential for the growth and development of wheat. The appropriate fertilizer dose varies on many factors, but generally involves the use of nitrogen, phosphorus, and potassium. Farmers should take care to conduct soil tests, apply fertilizers carefully, and avoid over-fertilization to maximize the benefits of their wheat cultivation.
