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, we can put forward the application method of nitrogen, phosphorus and potassium and, trace elements and so on in the period of fertilizer application quantity, fertilization . Informally, we can reasonably fertilize in agricultural science and technology personnel under the guidance of scientific fertilization  fertilizer. Soil testing fertilization technology is the core of the regulation and crop fertilizer and solving the

contradiction between the soil for fertilizer. Targeted at the same time, supping nutrients required for crop plants lack what elements are added what elements, how much we need to fill, achieve the equilibrium of various nutrient supply, meet the needs of the crop. To improve fertilizer use efficiency and reduce consumption, increase crop yield, improve the quality of agricultural products, labor saving, increasing the income of savings. 

At present, the development of the compound fertilizer has three trends: the first is the many kinds of measures. Different crops have different specific fertilizer,  according to the practices of the growth of crop and fertilizer consumption of the development and production. Farmers are to choose the corresponding specific fertilizer according to different crops. If we goes not against the rule of crop fertilizer absorption, we don't improve crop production potential and also causes some waste of nutrition elements. The second is the multi-function medicinal. To combine these with the pesticide and fertilizer, chemicals from the seed program, an application of crop nutrients needed can be ensured and prevention and control of underground pests and seedling diseases, can have multiple effects. The third is the high concentration of long-term. With the development of agricultural production, and long-term high concentration compound fertilizer is more and more welcomed by farmers, this type of fertilizer application reduced the dosage of fertilizer, convenience of farming, revoke application link, reduce the labor, improve the utilization rate of fertilizer, save work, energy, time, quality, and the efficiency. 

According to the characteristic of compound fertilizer to fertilize

Compound fertilizer effect is long and appropriate to the basal. A large number of tests show that are both binary and ternary composite base as well. This is because the compound fertilizer containing nitrogen, phosphorus, potassium and other nutrients, crop early especially for the sensitive, phosphorus and potassium requirement is to be a basal p and k fertilizers applied earlier. Controlled release compound fertilizer used in the process of production for coating and granulation process, smooth slow fertilizer effect, is slower than the elemental chemical fertilizer decomposition, nutrient leaching less, utilization rate is high, suitable for basal. General mu dosage for 30 to 40 kg. Compound fertilizer should not be used in In mid and late seedling fertilizer and fertilizer to prevent from TanQing moderate growth 

Compound fertilizer decomposition is slower, in compound fertilizers in sowing crops, so we should according to the practices of the different crops to fertilizer supplement available in time for the fertilizer nitrogen fertilizer to meet crop nutrient needs. 

Different concentrations of compound fertilizer, should pay attention to choose the right concentration. At present most of the compound fertilizer according to the average nutrient soil types in the area is good and the crop fertilizer proportion configuration. There are series of high, medium and low concentration compound fertilizer, the general low concentrations of total nutrient is between 25% and 30%, the concentration of is between 30% and 40%, high concentration is above 40%. In different region, soil and crops, we should choose to use economic and efficient compound fertilizer. Generally high concentration compound fertilizer should be used on the economic crops, excellent quality, less residue, high utilization rate. 

The ratio of compound fertilizer raw material is different 

So the use of the nutrient elements should be paid attention to. Different brands, different concentration of compound fertilizer by using different raw materials, production according to the soil type and crop species choose to use. that containing nitrate, we don't use in leaf vegetables and paddy field containing ammonium ion compound fertilizer,we should not be applied on saline-alkali land; that containing potassium chloride or chloride ion ,we don't avoid chlorine crops or on saline-alkali land use; that contains potassium sulphate , we should not be applied in the paddy field and acid soil. Otherwise, will reduce the fertilizer effect, and even poison plants. 

Plants need the element is not only the nitrogen, phosphorus, potassium, but also need calcium, magnesium and other elements, compound fertilizer contains actually refers to two or more than two kinds of the required elements fertilizer plants. Such as hydroxy calcium phosphate, ammonium nitrate, etc. Compound fertilizer plants should pay attention to the growth period, plant species, and application of the required elements of the compound fertilizer plants, conducive to the growth of plants. If a compound fertilizer applying too much, it can cause an element enrichment in plants and influence the plant growth, may also make the soil liquid concentration too high,finally it will appear the burning seedlings phenomenon.
