<br/><br/> "Soil fertility is a concept based on the amounts of essential nutrients available to the plants. The plant nutrients involve are classified as macronutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur or as micronutrients such as iron, manganese, copper, zinc, boron and molybdenum. The amount of each of these nutrients is  not the only factor in determining whether there are nutrients shortage."--Back cover<br/>
