What is soil series according to the manual, check the soil series. Keep the soil samples come SNP k monitor verification by PK-n in soil. N-PK values of the monitor to compare in the fertilizer recommendations provided that much amount of fertilizer.6. to advise the fertilizer phosphorus and potassiumIn the case of phosphorus had been used, the program, which was developed at the University of Hawaii, used to introduce each of soil phosphorus in fertilizers. Best use of soil potassium recommendations of Department of agriculture so that the fertilizer recommendations for corn have all 3 elements.The experiment in the field1 test procedure advise fertilizerTest procedure advise fertilizer experiments 11 conversion of corn in 4 provinces by academics and other tests the conversion's 56 officials promoting agriculture. From the output and yield predictions by the program are very similar in the case of a scholar, but in the case of a student who is promoting the agricultural operation. An error by up to 50%, this may be due to an error in the measurement of the amount of nutrient n p k using the batch monitor, NP k in soil or there was an error in checking soil series.2 study guide, fertilizer from the program compared to the use of fertilizer for farmers.A comparison has been made from fertilizer recommendations using the program with the farmers. It was found that the use of the fertilizer recommendations. this development has produced higher and higher by the gains will convert the test designed in conjunction with the private company, 15 2 companies and make the conversion in all areas of the other four farmers.Convey research to farmers.Department of agriculture has supported projects to promote animal by-products by training farmers, 200 people and officials to promote agriculture in the 10 provinces, planting 200 corn in the year 2544 (2001) by promoting agricultural seed and fertilizer value design, with each farmer participant 5 acres and the farmers trained and 40 people found one corn planting operations, based on the method of tropics are coming. With officials to promote agriculture as a trainer Therefore, the farmers are expected to plant corn is 8000 people using the fertilizer recommendations in this area, 200000 acres development.The year 2545 (2002)-2547 (2004) brought the route to power to farmers who decide to come to qualifying farmers brought the number of 67 people from lop buri, phetchabun, Nakhon sawan province is 4, and Nakhon Ratchasima. Farmers leaders have extended the 67 members 627 people and farmers of 338 people have planted maize using techno-Jonathan Lee managed only the fertilizer, corn has a higher yield and more profitable for farmers. Reforestation expenses or costs reduced (table 3.1) has extended to the farmers to plant corn and other province by farmers who receive training from the project.Table 3.1 average analysis of yield and yield during the conversion of a specific nutrient management and soil analysis, non-farmer got in 4 provinces.1 Note/farmer who does not have land 2/conversion analysis, nutrient management, only a statistical difference in 3/95% level 4/statistical difference in level 5/99% statistical differences are no corn price = 4.2 baht/kg.Problems of research transferFrom farmers to meet with the farmers to plant corn using the fertilizer according to the instructions of the year 2544 (2001). that many farmers did not put the fertilizer according to the instructions in spite of the monitoring of soil and soil series come SNP analysis applications, there are several problems.1. the formula of fertilizer because the fertilizer recommendations in this guide has been developed to provide fertilizer as nutrient. This can be done easily if you use fertilizer, but on condition of the market, the use of fertilizer, farmers in the past, it is often used as fertilizer, fertilizer, that are available in the market. Thus, problems in finding a formula of fertilizer according to the instructions is not.2. Wan fertilizer Most of the farmers grow corn by hiring from the fertilizer, planting and harvest. The machine currently fertilizer is the same quantity of fertilizer. Cannot be modified because the farmers use fertilizer formula one and one equal in quantity, but the advice in this guide have been developed at the fertilizer quantity fertilizer from 7 kg/50 kg/Rai farm until, depending on the quantity of nutrients in the soil, soil type and rainfall, so farmers can use fertilizer recommendations that have been developed.3. liabilities liabilities are farmers with middlemen or fertilizer dealer by creating increased debt from the removal of fertilizer used by the merchant Guide. Therefore, the fertilizer according to the instructions of the middlemen.4. corn prices slump The farmer was exploitation from the middlemen in the price of corn and deliberate in weighing, moisture and corn.5. the lack of knowledge of soil and fertilizer. Farmers lack knowledge and understanding of soil and fertilizer and soil treatment of the unknown self.6. the habit that I don't like the hassle. Thailand has a habit that farmers don't like doing anything difficult, therefore, to convey research, which is a step in the action than the original farmers may cause some farmers giving up and he doesn't want to use this research.7. the drought which is natural disasters. Can't be edited. Total area of corn grown relies on rain water only.8. high production costs due to the fertilizer, seeds and pesticides are expensive.9. the soil is not fertile.The result of the technology transferFrom the query, the farmers receive training in, some found that many farmers don't have the fertilizer that is checking the soil is soil analysis, because waiting for the seeds and fertilizers from agricultural promotion Department and there are problems in all but the 3.5 query information farmers from many who follow the instructions, I found that the maximum output and profits.
