These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others.
The main steps for agricultural practices include preparation of soil, sowing, adding manure and fertilizers, irrigation, harvesting and storage.
The prior step associated with seeding is crop selection, which mainly consists of two techniques: sexual and asexual.
This term is preferably used when large amounts of water is applied to dry, arid regions in order to facilitate plant growth.
In temperate and tropical areas rainfall and snowfall are the main suppliers of irrigation water, but in dry places with unfavourable weather conditions, groundwater serves as an essential source.
Underground wells also play an important role in storing water for irrigation, specifically in America, and Arizona, in particular.
