Soil nutrient loss
Soil fertility refers to the quantity and balance of soil nutrients available to plants for growth. Soil nutrients are divided into macro- and micronutrient categories depending on the quantities required by the plant. Important macronutrients include: nitrogen, phosphorus, calcium, magnesium, sulphur, carbon, oxygen and hydrogen. Important micronutrients include: boron, manganese, copper, iron, molybdenum, zinc, cobalt, chlorine and silicon.
