PH values in acid-alkali soil of substances Measuring units, together with pH, which is usually available at 0-2, so if the soil pH values are equal to 7, it shows that there is pH-neutral, but if there is a lower pH value of 7, showing that the soil has very acid soil pH values if there are higher than 7, it shows that there is a high alkalinity, which is generally the soil.Usually there are 3 acid and alkali is 10 by environmental factors are examples of nutrients received land, such as the fossil at the mess, and the average rainfall per year is a component which has a value of approximately 6.5 pH soil to plant a tree is the best because it has a relatively neutral value, but there will be some plants such as blueberries, azaleas, PUD that will grow well in acid. The pH value of the soil is 4.5-5.5, etc. Called the find before planting trees. With the study of soil pH value.
