The problem of soil degradation in areas with saline soil originates from chemical and physical degradation and low fertility which are main limitations for land use, including shortage of water in the dry season and intermittent rain during cropping season. Farmers in the area of growing rice every year between May and October by implementing wisdom going through error-trial farming including knowledge gained from performing duties as soil doctors stationed at Non Thai district, Nakhon Ratchasima which is done by growing vegetables for export supported by Marketing Organization for Farmers, Non Thai district, Nakhon Ratchasima province cooperating with private companies. Regarding soil amendment for planting vegetables in the Northeast, the method to increase and keep the fertility level throughout the harvesting season, including off-season production of chili spur pepper is to increase organic matter and plant nutrients, and to adjust pH values to be suitable. They can be planted in the irrigation zone throughout the year. However, the best time for planting them is in the period of January and February which is when chili peppers have good prices. For areas outside the irrigation zone, they should be planted in the rainy season. Chili peppers can thrive in every kind of soil, but the most suitable soil is sandy loam. They do not like waterlogged or wet areas because this condition can cause the root to become rotten and the plant to die easily. The form of planting chili peppers in Thailand is different according to soil characteristics. In any case, whatever methods are used,farmers place importance on procedures of cultivation preparation, watering as well as maintenance for diseases and insect prevention. This also includes vetiver as soil covering
together with application organic fertilizers, fermented bio-extracts and useful microorganisms. Good soil management will make chili trees become strong and disease and insect resistant. This has been brought about challenges to overcome the nature with limitations in terms of soil, water and the environment whereby there is a motto lived by stating that "There is nothing easy and nothing difficult either if we understand the nature before taking actions. Do not view money as denomination, but look at the value of products to occur at first."
