Tunnel irrigation

Tunnel irrigation must be designed, managed, and maintained to provide the right amount of water at the right time for the crop to grow optimally. In most cases micro-irrigation (drippers or micro-sprayers) is used, and modern micro-irrigation has developed from a simple water source management system to a complex, knowledge-intensive management system that manipulates the…

Micro-irrigation

Micro irrigation is considered as one of the most efficient irrigation systems, but it should be management and maintained properly to keep it to perform at its best to enhance crop growth and water productivity. The concept of micro irrigation originated during the initial “discovery” and development of drippers and drip irrigation in Israel. However,…

Drip irrigation

The purpose of an irrigation system is to apply the desired amount of water, at the correct application rate and uniformly to the whole field, at the right time, with the least amount of non-beneficial water consumption (losses), and as economically as possible. Irrigation systems in use are classified as follows: Flood or gravity irrigation…

Water smart irrigation

A requirement for sustainable agriculture in the water value-chain Water, especially in irrigated agriculture, poses one of the most vital sustainable development challenges of our time. The importance of water is as follows: Water is the key to food security: without water, crops simply cannot grow. Water is not just for primary production it plays…
