It is a measure of the total soluble salts in the soil. If the salt content is less than 0.1 g, there is no absorption of any nutrients. There is a relationship between pH and EC, if pH is alkaline and EC is acidic, the salt content increases and becomes more acidic, and if pH falls below 6, it is called acidic soil. In both cases, the absorption of nutrients in the soil increases the yield of the crop. For example, if the soil pH is 8-8.5, the nutrients in the soil become unavailable to the crop. Even if macro nutrients like Calcium, Magnesium and micro nutrients like Zn, Fe, Cu are present in the soil, they become unavailable to the crop. Then the crop will have to face deficiency symptoms and yield reduction. This leads to natural and healthy growth and the crop will be strong. Therefore, there are ways to keep the soil pH neutral. The soil should be tested every three years and kept in good condition. Soil testing is essential. The amount of Calcium, Magnesium and micro nutrients should be applied in the required quantity. You will not know the amount of nutrient and micronutrient in the soil without testing. This document provides a method of providing advice for soil analysis and testing. The soil pH (6.5-7.5) is essential for crop growth. Excessive agricultural use, excessive irrigation, and factors like soil erosion increase the pH in the soil. If it exceeds 6, it is called alkaline soil, and if it falls below 6, it is called acidic soil. In both cases, the absorption of nutrients in the soil increases the yield of the crop. For example, if the soil pH is 8-8.5, the nutrients in the soil become unavailable to the crop. Even if macro nutrients like Calcium, Magnesium and micro nutrients like Zn, Fe, Cu are present in the soil, they become unavailable to the crop. Then the crop will have to face deficiency symptoms and yield reduction. This leads to natural and healthy growth and the crop will be strong. Therefore, there are ways to keep the soil pH neutral.
