WebJan 1, 2024 · Bray's concept states that “As the mobility of a nutrient in the soil decreases, the amount of that nutrient needed in the soil to produce a maximum yield increases from a variable net value, determined principally by the magnitude of the yield and the optimum percentage composition of the crop, to an amount whose value tends to be … WebBray’s Nutrient Mobility Concept. Management of nutrient inputs to correct deficiencies is closely linked to whether the nutrient is mobile in the soil or not. As the mobility of a nutrient in soil decreases the amount needed in the soil increases from a value equal to the product of maximum yield and optimum plant composition to a constant.
