Is there a big difference between fertilizing and burying and directly laying on the surface of the

For the subject raised, is there a big difference between the effect of fertilizing and burying the pit and directly laying it on the soil surface? Why? As an old farmer, Wei Nong wants to talk about his own views on this issue.

In fact, as a farmer, we all know that sprinkling and ditching fertilization are the two fertilization methods that farmers often use when planting crops. These two fertilization methods have their own advantages and disadvantages, and the effect is also different. Relatively speaking, it is simple and trouble-free, but the nutrient loss of fertilizer is relatively large, the utilization rate is not high, and the effect is relatively poor, and the ditching fertilization is more laborious and laborious, but the fertilizer is not easy to volatilize and lose, and the utilization rate is relatively high, and the effect is better.

The situation is different in different places, when our farmers here plant crops, the bottom fertilizer is generally evenly spread on the ground when rotary tillage is used to prepare the land, and then the fertilizer is fully mixed with the soil through rotary tillage. For apple trees, in late autumn and early winter, when the bottom fertilizer is applied, the method of digging strip-shaped trenches or radial trenches under the vertical extension of the canopy will be adopted to apply various fertilizers deeply.

Since we are a dry farming area, there is a lack of water and no irrigation conditions, so when farmers top dressing crops, they generally adopt two methods for top dressing. The first is to adopt the method of sprinkling urea for top dressing. For example, our farmers here will sprinkle urea with the help of rain and snow every year before and after the wheat returns to green, or sprinkle urea with the help of urea when the soil is still relatively moist after the rain to supplement nutrients to the crops during the corn trumpet period.

Another way is to ditch and fertilize. For example, when topdressing corn, most of them take the method of ditching between the rows to fertilize and bury the soil, and there is also the method of topdressing apple trees, which is also the method of digging pits and deep application.

Of course, farmers do not know how to sprinkle chemical fertilizers, which will cause nutrient loss, but because of the lack of water here, and it is not easy to fertilize wheat in dense ditches, so farmers have to sprinkle more when topdressing. For those crops that are not too dense, especially apple trees, farmers also mostly dig pits and top dressing in order to reduce nutrient loss when conditions permit, so as to improve the utilization rate of fertilizer.

To sum up, relatively speaking, the fertilizer is sprinkled on the ground, especially the nitrogen fertilizer that is relatively volatile, and the utilization rate of fertilizer is indeed not high, such as if the temperature is relatively high, it is easy to cause the volatilization of chemical fertilizer, and it is also easy to cause fertilizer damage, and if it is sprinkled before rain, if the rainfall is relatively large, the fertilizer will be lost with the rain. Therefore, when fertilizing crops, the best fertilization method is still ditching and deep application, which is better than direct sprinkling.

The difference is quite large. When fertilizing and burying, the plant rhizomes can absorb nutrients faster, which is a kind of rapid fertilization. If it is spread directly on the surface, it will take some time to slowly penetrate into the roots.
