Irrigation has been important to farmers for over 4,000 years. There is evidence of irrigation along the Nile river dating back as early as 2600 B.C. It is suggested that crop irrigation strongly contributed to the founding of civilization. The use of fertilizers increased dramatically during the 1970s and 80s. Fertilizer has increased crop yields and reduced hunger more than any other single agricultural practice. Fertilizer influences soil characteristics, some can be beneficial, and others are not. There are 16 elements knows to be essential for plant growth and development. Most are used by all plants. However, there are some that are only beneficial to specific types of plants under certain conditions. These elements are Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sulphur (S), Iron (Fe), Manganese (Mn), Molybdenum (Mo), Copper (Cu), Boron (B), Zinc (Zn), and Chlorine (Cl). Some plans called Halophytes can require Sodium (Na) and there are also some nitrogen fixing microorganisms require Cobalt (Co) to function.
Nutrients: Macro and Micro
Nutrients are grouped into two different categories; Macronutrients and Micronutrients. Macronutrients are the primary mineral nutrients used in the largest quantities. They include: Nitrogen, Phosphorus, and Potassium (NPK). The Secondary Nutrients used in smaller amounts are Calcium, Magnesium and Sulphur. The rest of the nutrients are Micronutrients and are sometimes referred to as trace elements. These are used in the lowest amounts if at all depending on the plant species.
