Fertilizer and agricultural fertilizers using technology

The production practice shows that about 70% of the nutrients absorbed by the crop during its growth and development come from the soil, and the level of soil nutrient content mainly depends on the amount of agricultural fertilizer.

In recent years, there are many tendencies for farmers to fertilize. One is to use large amounts of chemical fertilizers and to increase grain yield by chemical fertilizers. The result is that although the grain yield has been increased, the soil organic matter content has also been greatly reduced. The other is the individual application of farmyard manure. Although the result is fertilizing the soil and reducing the production cost, the grain yield is not high. In order to increase grain production year by year, the more the land becomes “fat”, the practice has proved that it is necessary to use chemical fertilizer and agricultural fertilizer to use this road.

Benefits of using

1, both land and raise land. According to experiments, the use of chemical fertilizers in combination with agrochemical fertilizers for 3 years is 0.08%-0.11% higher than that of single chemical fertilizers, ammoniated bacteria is increased by 260%, aerobic nitrogen-fixing bacteria is increased by 119%, fiber breakdown Bacteria increased by 600%.

2, high yield and high quality food. Fertilizers and agricultural fertilizers are used in the middle and low-yielding fields, which can increase production by 20%-50% compared to single-fertilizer, and the quality of grain is also greatly improved.

3, reduce fertilizer losses. The test results show that the use of chemical fertilizers in combination with agricultural fertilizers can not only reduce the soil redox potential and reduce ammonia nitration, but also reduce the loss of nitrogen. Generally can improve nitrogen fertilizer utilization by 10% -20%.

Collocation requirements

1, master the application time. Farmers have a large number of fertilizers and have a slow effect. They should apply as early as possible. Generally, they should do base fertilizer before sowing. However, the use of chemical fertilizers is small and the effect is quick. Generally, it should 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 cars per acre, ammonium nitrate 30-35 kilograms, three phosphate 13 kilograms; on medium fertility soil, can apply fertilizer 2 cars per acre, ammonium nitrate 30 kilograms , 10 kg of three material phosphate fertilizer; in high fertility soil, can apply fertilizer 1-2 cars per acre, ammonium nitrate 25 kilograms, three kilograms of phosphate fertilizer 8 kilograms.
