The high temperature and rain in summer are beneficial to the growth of various crops. And the sun is abundant, which is conducive to the photosynthesis of the leaves. The carbohydrates produced by crop photosynthesis require large amounts of nitrogen to form amino acids, proteins, and nucleic acids. Summer is a vigorous growth season in which vegetative and reproductive growth of crops alternates. The rapid growth stage of crops requires large amounts of nutrients, especially nitrogen and potassium, so topdressing is required.
Field crops mainly apply nitrogen fertilizer, and economic crops such as vegetables, grapes, cotton, etc., in addition to nitrogen fertilizer, also apply potassium fertilizer. For example, for spring corn crops, the urea one-time base fertilizer application is used as a reference, and the other half of urea is used as top dressing and applied at the end of July and early August. The latter's nitrogen fertilizer utilization rate can be increased by 10 to 20 percentage points. This shows that the utilization rate of topdressing nitrogen fertilizer is significantly higher than the application method of all nitrogen fertilizer as base fertilizer. Regarding the method of topdressing nitrogen and potassium fertilizers in summer, the trench must be covered with soil to avoid the loss of nitrogen volatilization caused by the surface application of nitrogen fertilizers and the potassium fixation of potassium fertilizers on the ground due to the alternation of wet and dry conditions.

Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
