The moisture in the soil is between the mass of water in the soil to the mass of dry soil. In General, this proportion is between 0.05-0.5 g/g. Only dry soil only where the value is less than the normal low-value land in the desert with 0.05 g/g soil and high chemical อินทรีย. Soil crust or clay that water treatment is higher than 0.5 gram/grams. The measurement of soil moisture content in the soil of the tell in the ecosystem. For example, refers to the ability to absorb water, or water flowing in the earth caused by the flow of underground water. The flow of water surface evaporation and dehydration and water to the atmosphere, and also is used to describe the ability of the soil to provide nutrients and water to plants that affect growth and survival of plants.How to find the geographical coordinates with a GPS1. collect samples of soil at a depth of 10 cm, each at least 3 examples point to repeat measuring 3.2. write a label showing the details of the land, such as, for example, the study points to the depths of the Earth. The name of the store, for example, the Earth. A day at the store, for example, the Earth.3. weigh the sample was established, the land each dialogues.4. take a sample of the soil to the baking temperature of 95-105 degrees Celsius for a period of 24 hours.5. the weighing of each soil sample after baking, and then calculate the values for humidity according to a formula. Is as follows:The moisture in the soil (g/g) =. The mass of the Earth, wet-dry mass of soil.The mass of dry soil.
