A Fertilizer or fertiliser is any material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants.
Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration. This article, like many on fertilizers, emphasises the nutritional aspect. Fertilizers typically provide, in varying proportions.
Fertilizers are classified in several ways. They are classified according to whether they provide a single nutrient (e.g., K, P, or N), in which case they are classified as "straight fertilizers." "Multinutrient fertilizers" (or "complex fertilizers") provide two or more nutrients, for example N and P. Fertilizers are also sometimes classified as inorganic (the topic of most of this article) versus organic. Inorganic fertilizers exclude carbon-containing materials except ureas. Organic fertilizers are usually (recycled) plant- or animal-derived matter. Inorganic are sometimes called synthetic fertilizers since various chemical treatments are required for their manufacture.
We mainly supply Phosphate fertilizer, such as: MAP, MKP and Silicate fertilizer, like: Potassium Silicate

Concrete wear-resistant pump installation method
The application of concrete wear-resistant pumps during installation and commissioning is very important, according to how to use concrete wear-resistant pump pipe directly related to the progress and quality of the project, the author set many years of concrete pump design, production technology and field construction accumulated experience Make some exhaustive overview of this. When installing concrete pump to consider the application of concrete. In the case of concrete, mixing and truck feed, the wear-resistant pump tubing can be installed in place as long as it is convenient to take over and feed it. If the scene is mixed with concrete, first according to the site and mixing and machine feeding way to determine the mixing and machine position, and then according to mixing and machine discharge height and wear-resistant pump to send and take over the tube to determine the requirements to determine the concrete pump s position. 1. Start placing the concrete pump on a solid concrete floor or stone pier to maintain the degree and lock the positioning pins and safety pins of the four legs of the pump to get the tires off the ground or remove the tires. 2. According to mixing and machine discharge port and abrasion pump tube hopper to make a chute, mix and discharge the material through the chute into the pump hopper. 3. The chute is usually made of angle steel, welded with 1.5mm thick steel plate. Under the chute with a support frame, so that the solid. 4 under normal circumstances, the wear-resistant pump tube hopper need to increase about 20cm, so increase the hopper volume to ensure that concrete will not drain. Because the mandatory mix and machine unloading the best finish unloading, so that the concrete flow into the hopper symmetry. If the grading discharge, the last out of the concrete stones too much, on the pump unlucky, especially when the slump of concrete larger, it should be noted that the hopper pump to be raised. If it is a large volume of mixing and machine, you can make a storage hopper in advance to ensure continuous feeding. 5. In the chute placed on the required slope appropriate, the most fortunate tilt angle between 25 ° -40 °, the gap should not be too large. 6. Chute and pump hopper connection, the chute and hopper to leave some space for easy cleaning hopper and sieve. 7. After installation in place, observe the whole, to ensure that the wear-resistant pump tube casing door switch freely, easy maintenance.
