Fertilizer Fertilizer {DEVICE FOR FERTILIZER APPLICATION}

The present invention relates to a fertilizer fertilizer for supplying an appropriate amount of powdered or granular fertilizer in place to improve the growth of crops and to increase the yield to the soil sown or prepared.

In general, fertilization refers to the supply of fertilizers consisting of nitrogen, phosphoric acid, potassium, etc. to the soil in which the crop is sown or prepared. The ingredients are fed to produce good fruit and the yield is increased.

The method of fertilization can be classified into various types according to the type of crop or the characteristics of the soil. Typically, the fertilizer is sprayed by spreading the fertilizer over the entire soil area, and the fertilizer is supplied only to the part where the crop is sown or prepared. It can be classified in the form of local fertilization.

The full-layer fertilization method has the advantage that the time required for fertilization is shortened and convenient, whereas the fertilizer is used a lot and the fertilizer is not uniformly supplied to all crops, and the growth rate of the crop is locally different. There is a disadvantage that it can be lost without penetration.

In addition, in the case of local fertilization, there is an advantage in that it is possible to supply a sufficient and appropriate amount of fertilizer to all the crops, while it is disadvantageous in that the fertilizer takes much time and is inconvenient.

Accordingly, various types of fertilizers have been proposed to improve the shortcomings of the local fertilization method. For example, Korean Utility Model Model Nos. 20-0207081, 20-0292921 and 10-0442210 are registered. will be.
