Soil pH alters the ability of plants to uptake certain nutrients. So even if, let's say, there was enough nitrogen in the soil for all of a plant's needs, if the soil was very high or low in pH, the plant wouldn't be able to access it anyway. read more
Soil is an important resource that can take hundreds of years to form. Plants rely on soil to obtain nutrients along with water and gases. The pH of soil ranges between 4 and 8 and an optimum soil pH is somewhere between 6 and 7 for plants to be able to grow. read more
Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases, the soil pH decreases, thus becoming more acidic. read more
