  • Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
