The use of fertilizers to meet the needs of the plants and the fertility of the soil in the planting area is ideal. Because the yield too little fertilizer is not good enough. Adding too much fertilizer can cause wasteful spending, can cause susceptible plants. The soil used in the cultivation of a different more than 200 sets of each clay soils have different properties when used in cultivation. In addition, each area of ​​the earth, it has plenty of different. Therefore, the use of fertilizers to meet the needs of the species and plant species. We need to identify the soil and require a thorough analysis of the fertility of the soil before planting and fertilizer. The application calculates the tailor-made fertilizers and fertilizer according to soil analysis to calculate and display the instructions for use compost as soil type specified. The calculated results based on the input of soil analysis and soil improvement. After that displays instructions to get the nutrient fertilizer nitrogen (N), phosphorus (P) and potassium (P) is the mother of three of the fertilizer is urea (46-0-0) DAP. (18-46-0) and MOP (0-0-60) for the fertilizer each time. In addition, the amount of fertilizer on farmland. Calculate the number of sacks of fertilizer required for each parent. Calculate a price to purchase a fertilizer. And the cost of fertilizer per hectare. Therefore, the use of fertilizers or manure to the soil to cut unless the nutrient needs of plants, but also more cost effectively reduce waste and reduce environmental impact.
