Supply "Fertilization Calculator" products 
 The product was repeated more than two decades a large number of field tests, fertility experts brought together the provinces, Shihezi University, Xinjiang Academy of Land Reclamation, autonomous regions and Soil and Fertilizer Station of experts, and many other well-known for decades of fertilizer research results will be complex and lengthy high side technology materialized as easily master the application of the peasants, "fool" calculator. 
 1, field test and validation areas 
 The products in the country and more than 120 representative of Xinjiang region, choose a different climate, different textures and different effects of fertilizer on the crops and "3414" regular trial. 1350 test data collection areas nationwide, covering most parts of the country must, to master the different systems in different soil texture and nutrient uptake of crops, fertilizer use efficiency, soil nutrient efficiency are factors, indicators of soil nutrients and many other parameters and fertilizer laws. The region was established soil nutrients index model, target yield and nutrient uptake parameter model, soil nutrients (nitrogen, phosphorus, potassium) is coefficient of efficiency parameter model. Through a large number of over twenty years of field testing and data collection, statistical processing, research compiled more than twenty integrated fertilizer response function fertilization model dynamic parameters. 
 2, reliable technology, high accuracy 
 The product uses the time more than 10 years, cities and counties in Xinjiang, more than 120 national and regional representative of the field verification and 550 million mu in large scale shows that the yield of various crops in the 5-25% range on average, fertilizer can be saved scalar 2-5kg / mu, the average increase revenue in the 16-150 yuan / mu. This product technology and reliable, the calculated proportion of scientific and rational K, and combination of local realities, accuracy rate of 95% or more. 
 3, simple operation and wide applicability 
 This product is extremely simple procedure, in accordance with the calculator prompts the right choice, such as the choice of crops planted by farmers and target output, select the level of land fertility, soil texture, irrigation methods, soil nutrient testing the value of the basic conditions to can be fast and accurate calculation of the farmers need the physical volume of fertilizer and fertilizer formula to calculate the amount of fertilizer can be combined with the actual level of farmers, the error does not appear the phenomenon of fertilization. Fertilizer application and formulation can be calculated directly to the section field, can guide the farmers, "according to the amount by side" fertilization. This product is for farmers and rural development using scientific and technical personnel, mainly for cotton, winter wheat, spring wheat, barley, rice, corn, soybeans, sorghum, millet, sugar beet, sweet potato, potato, sunflower, rapeseed, peanuts, grapes, tomatoes, apples, pepper, melon, pear, red dates, playing melons, safflower, medlar, hops, carrots, sesame seeds and other 30 kinds of crops. 
 4, product quality and after-sales service 
 The products are popular products, ensure product quality. Introduction of free long-term after-sales service, free upgrades, free adjustment of parameters, free maintenance and replacement. Make every effort to meet the local work carried out soil testing and fertilizer. 
 5, product sales 
 Products for national wholesale and retail, price negotiable.
