All crops require nutrients and water to grow. Soil supplies most of the nutrients. It also stores the water that the crops need. Crops differ, however, in the amount of nutrients and water they require for healthy growth. A farmer must therefore make sure that the soil and water resources meet the needs of each crop. A farmer must also plan measures to control pests, which could damage or ruin a crop. Most farmers plan their methods of soil and water management and of pest control well in advance of the growing season.

All plants require certain conditions of the environment for their best growth and development. The most important of them are water, soil, sunlight and temperature.
Without sunlight many important processes in plants do not take place. One of them is photosynthesis by which plants produce food from inorganic materials.
Besides water the soil in which crops are grown is to be provided with air and all necessary nutrients. The most important plant nutrients are nitrogen, phosphorus and potassium. There are at least 14 elements that are essential for proper plant growth. Farmers have to apply the nutrients taken by growing crops from the soil.
