The average pH level of a soil in most countries ranges between 6 – 7.5. This is approximately neutral zone. Although many plants have adapted to different pH levels than given in the range. The Minerals needed by the plants are Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Carbon-dioxide and Oxygen, Boron, Copper, Iron, Chloride, Manganese, Zinc and Molybdenum Lime is sometimes added to reduce the acidity of the soil. In the presence of these minerals and pH level plants grow to their maximum and very effectively. However there might be some causes that might affect their growth or fertility. Some reasons might be pests, access water, insufficient or access minerals, the soil might be too acidic or alkaline or all of them. This situation has recently occurred in Thailand and a mass majority has been affected. The recent floods have affected the fertility of the soil, causing huge loss to the nation. The very recent 2011 floods caused a huge variation in the soil of Thailand. Floods have affected the ph level of the soil as well as the nutrients in Thailand. Thailand is the world’s largest rice exporter. Due to a series of major flooding, the amount of rice production in Thailand has dropped drastically. Flooding caused in factories, resulted in chemical waste being transported by the water in to the farmlands. Causing plants to suffer as they are not adaptable to their current environment. This affects the growth of the crops immensely. The chemicals cause a change in the pH level of the soil, as well as the change in nutrients. As the water flows it also passes the drainage system, the water then carries the human waste, and when the water drains out the waste is left there which later on attracts various kinds of pests, and they might harm the crops. Over all the flooding causes a huge loss and also its affects are long term. Major steps should
