Field fertilizers should be deep

At the moment, many farmers’ friends are trying to save time by fertilizing their crops. They spread chemical fertilizers on the surface of the fields, causing serious losses of chemical fertilizers. At the same time, they have increased environmental pollution and the crops have not received corresponding nutrient requirements, resulting in crop production losses. Therefore, farmers' friends should change this unfavorable fertilization method and deepen the application of chemical fertilizers. This will not only reduce the loss of chemical fertilizers, increase the fertilizer utilization rate, but also help the crops better absorb and use, and at the same time reduce environmental pollution and increase production. The effect of increasing income. According to experiments, after the deep application of nitrogen fertilizer, the average utilization rate can be increased from 30% to 40%. The deep application of phosphorus and potassium fertilizer can reduce the loss of wind erosion, promote crop absorption, extend the fertilizer effect, and increase the yield generally by 5% to 15%.

Deep application of fertilizer can be divided into the following three categories: Bottom Fertilizer Deep application of base fertilizer Deep application method There are two kinds: First, after the first fertilizer, ploughing; Second, the side ploughing and fertilizer applied to the furrow. The second method is better. The required depth of fertilization is 6 cm, and the width of the fertilizer is 3 to 5 cm. The rows of fertilizers are evenly distributed and there are no obvious broken strips.

Fertilizer deep application of seed fertilizer deep application requires species, between the fertilizer can form a certain thickness, generally more than 3 cm to meet the nutrient needs of the crop growth at seedling stage, can avoid burning, burning seedlings phenomenon.

Deep dressing topdressing is deep in the crop is 10 to 20 cm from both sides of the plant line, take a small ditch or hole method, the depth of 6 to 10 cm, fat bandwidth of 3 cm or more, pay attention to cover soil after fertilization.
