What is the difference between controlling and release of fertilizer and mild release fertilizer

What does it mean to control the Fertilizer?

Controlling Fertilizer is a high -form form of slow -release Fertilizer. It mainly controls the release of nutrients through envelope technology to achieve the purpose of safe, long -term and efficient. It is the main direction of modern Fertilizer development. It is suitable for mechanized production. The broadcast needs to wait.

What are the characteristics of controlling Fertilizer

The first is to increase the utilization rate of chemical Fertilizers and reduce the amount of Fertilizer.

Because controlling and release of Fertilizer has a slow -release effect, it can reduce the gaseous and leaching loss of chemical Fertilizers, thereby improving the efficiency of the utilization of chemical Fertilizers.The test data shows that the controlling Fertilizer can increase the utilization rate of Fertilizers from about 35%, and the loss rate of nitrogen fertilizer is significantly reduced, which can save 30%-50%of nitrogen fertilizer.

The second is to reduce the number of Fertilizers and save labor.

Due to the lack of labor in rural areas or due to lack of water and inadequate water supply, crop fertilization is becoming increasingly simplified, and one -time fertilization of crops is quite common.At present, the one -time Fertilizer sold on the market is basically fast -acting high -nitrogen -type Compound fertilizer, and there is a risk of long -term seedling or later Fertilizer.The release of the release of Fertilizer can be scheduled to design the release mode of the Fertilizer in the growth season of the crop, so that the law of the nutrient release of the Fertilizer is consistent with the absorption of crop nutrition, and one -time fertilization meets the needs of the entire growth season of crops.

Controlling Fertilizer can also be used for cultivation of farming and soil -free cultivation. seeds and Fertilizers can be sowed, and irrigation is sufficient, which is very convenient.Many soil -free cultivation of irrigation nutrient solution.Sometimes the nutrient solution is not well matched, and the Miao Changshi is not good. It solves this problem with controlling Fertilizer.

The third is to reduce crop disease and improve the quality of agricultural products.

Crop disease and product quality are related to the amount of nitrogen fertilizer. Applying controlling and release Fertilizer can prevent crops from absorbing excessive absorption of nitrogen, thereby suppressing diseases and improving quality.

How to use release Fertilizer

When using, Fertilizer isolates and covers soil after application. For example, when planting corn and cotton crops, the distance between the seeds and Fertilizers is about 7-10 cm, the depth of fertilization and sowing is about 10 cm.

Note:

1. When the use of controlling Fertilizer is used, the amount can generally be applied according to 80%of the Fertilizer in previous years. At the same time, it is necessary to increase or decrease appropriately according to different crops, target yield, and soil conditions.

2. Not suitable for the use of drought land and sandy land.In the absence of moisture, nutrients cannot be effectively released, which may cause crops to affect the growth due to the inability to absorb effective nutrients and cause crop production to reduce production.

The difference between control release Fertilizer and slow release Fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients by performing envelope on the Fertilizer. The Fertilizer has a longer Fertilizer and more nutrients, but it is only suitable for use in the peak of the crop. , Roots and mountain spray irrigation.

Smooth -release Fertilizer: The Fertilizer effect is relatively slow, and its composition is relatively single. The main elements contained in are nitrogen elements, and the water solution itself is relatively low.

The difference between controlling and Compound fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients through envelope technology. The Fertilizer effect is longer, and the nutrients containing are relatively comprehensive, but it is only suitable for crops to use it at the peak of the need for Fertilizer. Roots, mountain spray irrigation, etc.

Compound fertilizer: It mainly contains nitrogen, phosphorus, potassium and other elements. It is generally appropriate to fertilize (gap, acupuncture, etc.) when fertilizing, and it is usually used as base Fertilizer.
