We are offering mixed fertilizer. Compound fertilizer refers to the three nutrients in nitrogen, phosphorus and potassium containing at least two kinds of nutrients, by chemical methods and (or) fertilizer made of mixing method. Any two elements of nitrogen, phosphorus and potassium fertilizers referred to as a binary compound fertilizer. Also contains three elements of nitrogen, phosphorus and potassium fertilizer called ternary compound fertilizer, and with the cooperation of n, p2o5 k20 - type according to the percentage content of nitrogen, phosphorus and potassium. Compound fertilizer is based on the total nitrogen, phosphorus and potassium considering that nutrient content is different, it can be divided into low concentration (25% of the total nutrient acuity, Compound fertilizer is separately made of chemical reaction and containing nitrogen, phosphorus and potassium fertilizer two or more elements and have a fixed molecular formula of compounds with the nutrient content and proportion of fixed. Such as potassium dihydrogen phosphate , potassium nitrate, monoammonium phosphate, diammonium phosphate, etc. Evelyn saler hebei longhai fertilizer co., ltd.

We are offering compound fertilizer nitrogen, phosphorus and potassium , there are at least two nutrients in the three nutrients showed that the amount of fertilizer made of chemical methods, it is also a kind of compound fertilizer . Compound fertilizer has high nutrient content and less vice composition and physical properties is good for an advantage, for balancing to fertilize, improving the utilization rate of fertilizer and promoting high and stable yield of crops has a very important role. But it also has some disadvantages, such as it is always a fixed proportion of nutrients, and that needed for different soil and crop nutrition element types, quantity and proportion is varied. Before fertilizing , we have the best to place a soil testing, therefore, we can understand the field soil texture and nutritional status. Except that we can also pay attention to the unit of fertilizer application to obtain the better effect. With the increasing of food production, the phenomenon of soil nutrient deficiency is showing, farmers now choose more multivariate compound fertilizer . Soil testing is more used to current compound fertilizer production formula to measure the soil nutrient, and it has soil testing and fertilizer field experiment as the foundation, according to the practices of the crop fertilizer, soil for fertilizer and fertilizer effect performance, on the basis of reasonable application of organic fertilizers evelyn saler hebei longhai fertilizer co., ltd.

We are offering tower compound fertilizer.
