H Ground Screws also called Screw Piles in some countries and it means Ground Screw Piles with helical blades. There are kinds of Ground Screw piles on our ground screw factory. The first type of Screw Pile is Ground Screw Pile with one helical blade, the second type of screw pile is ground screw pile with two pieces helical blades, the third one is screw piles with three pieces helical blades. But ground screw piles one piece helical blade is very popular with our customers because the friction with the ground is more than other types and many customers like this type of ground screw piles. Ground screw with helical blades can be used to Solar Ground Mounting System, garden decorations, farming fixing and so on.
Ground screw pile made in China and as one of producer of ground screw pile, we will recommend you two types of screw piles as your reference. One is about ground screw pile with one piece helix blade and another is about ground screw pile with two pieces helix blades, which both can be used to solar panel structures. As one type of solar screw piles, is very hot product on Finland and Thailand. It also be installed to the ground by Pile Driver as the support of solar panels or solar mounting systems. Screw piles as the related solar energy products are very hot sale products and they are very stable as supporting.
Some types of ground screw we exported can be used to construction field. Ground Screw with Nuts and Ground Screw with Flange, both types of ground screw will be installed if you want to use ground screw in construction field. We produce diameter 114mm-335mm of ground screw and length 1600-4500mm as your choose if you would like to purchase ground screw using to kinds of buildings. If you need these Ground Screw Anchors , please let us know, we will do some plans for you according to your requirements. In addition, Hot dipped Galvanized Ground Screw can not easy to be rust and it can be keep more than 25 years and the material of construction ground screw is Q235/Q235B/Q345 as your need.

Deep application. Whether urea is used as a base fertilizer or as a top dressing, it should be applied in deep soil, and the depth of fertilization is 10-12 cm. The deep application of urea can significantly improve the utilization rate.æ¤ test, urea application or shallow application of 2-3 cm, utilization rate of only 30%; fertilization depth of 5 cm, utilization rate of 45%; deep application of 10-20 cm, utilization rate of up to 65%.
Early application. Urea belongs to the ammonium amide fertilizer. It can not be directly absorbed by the crop after being applied to the soil. It needs to be converted into ammonium nitrogen in the soil to be absorbed by the root system. The application time is too late, which is not only harmful to the fertilizer effect, but also may cause The crops are late and ripe.
Foliar application. The urea molecule is small and easily absorbed by the leaves, and is the most suitable fertilizer for foliar application. Foliar spray is highly targeted, fast in absorption, free from soil factors, high in nutrient utilization, and low in fertilization, and significant in yield increase, especially in poor soil environment, excessive water or drought, soil peracid or over-alkali When the root absorption is hindered and the crops are in urgent need of nitrogen nutrition and the root activity is degraded in the late stage of crop growth, foliar application can compensate for the lack of root fertilizer.
Apply in combination with other fertilizers. Urea should be combined with organic fertilizer, phosphorus and potassium fertilizer and trace element fertilizer to maintain soil nutrient balance, maximize nutrient utilization and increase fertilizer production.

Urea contains 46% nitrogen, which is the most commonly used high-quality nitrogen fertilizer in production. However, the utilization rate of urea after being applied to the soil is usually only 45%-50%. So how do you improve the utilization of urea?
