Fertilizer and fertilizer can be “mixed”

In recent years, many farmers have two tendencies to apply fertilizer: one is the use of fertilizers in large amounts. In this way, although the grain yield has been increased, the soil organic matter content has also been greatly reduced. The other is the separate application of farmyard manure. Although the production costs are reduced, the food production is not high. In order to increase grain production year by year, the more the land becomes “fertile,” the use of fertilizer and agricultural fertilizer should be used together.

With the use of requirements: 1 grasp the application time. Farmyard fertilizers should be applied as early as possible, and fertilizer should generally be applied once before sowing. Fertilizers should generally be applied about 7 days before the crop needs fertilizer. 2 master the application method. Fertilizers should be combined with deep plowing into the soil tillage, or combined with ridging into the ridge bottom. The nitrogen fertilizer used in combination with the agricultural fertilizer can be used as a mouth fertilizer or top dressing, and the phosphorus fertilizer can also be used as a base fertilizer together with the agricultural fertilizer. 3 master the amount of fertilization. Fertilizers are used in combination with agricultural fertilizers, and the amount can be different depending on the crop and soil fertility. Such as corn, on thin ground, can apply fertilizer 2~3 vehicles, 30~35 kg of ammonium nitrate, 13 kg of three phosphate fertilizers per acre; on medium fertility soil, can apply fertilizer 2 cars, 30 kg of ammonium nitrate per acre. 10 kg of three phosphate fertilizers; on high fertility soil, 1 to 2 vehicles of agricultural fertilizer, 25 kg of ammonium nitrate, and 8 kg of phosphate fertilizer can be applied per acre.
