Development of fertilizer recommendation1. the production of the fertilizer recommendationsInformation to make recommendations for fertilizer plants in each area are limited and apply a very high budget for testing. Recommendations for fertilizer plants grown in soil. Unable to relay to Earth the same type in a different place, because there is a different temperature. Especially rainfall The Sun, because the confidence of making Thailand the most rain water.At present, foreign researchers have developed a program to calculate various types of plants, fertilizers, you can estimate the maximum returns and profits should be used to grow the number of fertilizer and said it suggested that one of the best known is the DSSAT release program for each type of plant, the current development of the plants, planting corn, this model was developed by 15 types of Hawaii at the same time. In the United States in the country. The program has three main categories of the database the database is a database of soil and climate. The plants database provides instructions for the type of soil. Corn หนึ่งและห corn varieties, fertilizer, parboiled, then type the location and the type of corn varieties from the database, which was embodied in the computer. Fertilizer recommendations This feature can be extended to other types of land improvement and other varieties of corn, wheat and other.2. the quantity of nutrient analysis.พืชจำลองโปรแกรมคำนวณเฉพาะไนโตรเจนปุ๋ยเท่านั้น ด้วยสมมติฐานที่ว่า มีฟอสฟอรัสและโพแทสเซียมเพียงพอ ก่อนที่ โปรแกรมจะคำนวณปริมาณของปุ๋ยที่จะทำให้ข้าวโพด มันต้องประกอบด้วยการวิเคราะห์ไนโตรเจนในดิน โดยการวิเคราะห์คาร์บอนอินทรีย์ในรูปของการ เมื่อคุณป้อนข้อมูลอินทรียปริมาณคาร์บอนที่มีอยู่ ในพื้นดิน ที่มีปุ๋ยไนโตรเจนต่ำ หรือปานกลาง หรือสูง โปรแกรมจะคำนวณจำนวนควรใส่กับพิมพ์กำไรสูงสุด ซึ่งมีค่าแตกต่างกันในแต่ละชุดดินแต่ละชนิดแต่ละ โครงการวิจัยได้ทำการปรับปรุงปุ๋ยไนโตรเจนคำแนะนำที่ใช้วิเคราะห์คาร์บอนอินทรีย์ในไนแองการาฟอลส์โฮเต็ล rotthaen เพื่อให้สอดคล้องกับผลการวิเคราะห์ โดยการตรวจสอบ n ตั้งค่า PK ที่วัดไนโตรเจนเป็นไนเตรต3. development of the k series in NPRemove the guide path, farmers use fertilizers. There is a problem with the carbon in the soil, because it อินทรีย quantity analysis in the laboratory has developed a set of auditing in NP, you examine the image 2 is a form of nitrogen, phosphorus and potassium are the aemmoniam and Niagara Falls hotel and check in with Musashi's extraction of a single substance, the quantity of liquid is able to distinguish NP k at a time, and adjust the quantity of phosphorus and potassium analysis method is suitable for use in aemmoniam nitrate fields, and use a simple device development. Save PK-n in the soil monitoring kit A tool to read the results in the laboratory by reading low or medium or high, and a 30 minute video.Is the validation of the standard tools that are used in the laboratory and found that 90-95% accuracy in the case of aemmoniam nitrate and phosphorus, but the accuracy of the reading is approximately 80% potassium only, it also found that there was a relationship with the organic carbon of soil rotnai on the outer dimension? Check the volume of the Earth by rotnai, Chennai to prepare a series of organic carbon Analyzer NP k instead of laboratory monitoring, so.4. check soil series.Because the corn crop yield forecasting and simulation of soil nitrogen fertilizer only. Therefore, Has developed a system for monitoring soil series, soil series, check out the book, by inspection, this is the only series of confirmation, which uses physical characteristics such as color, soil characteristics, 5 LP is acid alkaline soil and shallow coarse parts, etc.5. corn fertilizer recommendation process.Before I introduce the nitrogen fertilizer plant, the model for each series in each province. Farmers want soil before checking into the soil by is.what Guide to checking the soil collected soil come SNP k monitor verification by the PK-n in N is the value of the monitor to compare in the fertilizer, fertilizer, many.6. advise the fertilizer phosphorus and potassiumIn the case of phosphorus had been used, the program, which was developed at the University of Hawaii. Used in the introduction of phosphorus in the soil for fertilizer. Best use of potassium in soil of hints to guide agricultural fertilizer for corn have all 3 elements.Try it in the field.The step 1 testing, fertilizer recommendationsThe process of converting experimental fertilizer tests introduce corn in 4 provinces, 11 by academics and other tests the conversion of 13 agricultural promotion officials from productivity and yield predictions by program would look like in the case of students, but in the case of students, the promotion of agriculture. Up to 50% error may be caused by an error in the measurement of the amount of nutrient n p k by k NP in soil monitoring, or there is an error in checking soil series.
