Soil is the foundation on which we grow our food. World Food Prize Laureate Dr Rattan Lal compares soil with a bank account. We have to put more into the bank than we withdraw from it. This means that in order to improve the quality of soil (and crops), we will need to increase the soil’s organic matter content so that it can supply the plant with key nutrients.
Nitrogen is one of the essential elements that plants need to grow. They also need phosphorus, potassium, calcium, sulphur, magnesium and various micronutrients.
Nitrogen is an important component of chlorophyll, a pigment that plants use to make sugar and water, in combination with sunlight and carbon dioxide. It is also a key component of DNA, amino acids, and proteins. Nitrogen and phosphorus are components of ATP, which is a molecule that stores energy for all our metabolic demands.
