Fertigation using white poly bag Fertilizer mixed with water connected to a drip irrigation system. Fertigation is the injection of fertilizers, used for soil amendments, water amendments and other water-soluble products into an irrigation system. Chemigation, the injection of chemicals into an irrigation system, is related to fertigation.
Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.
A small center pivot system from beginning to end. Irrigation equipment can also be configured to move in a straight line, where it is termed a lateral move, linear move, wheel move or side-roll irrigation system. [11] [12] In these systems the water is supplied by an irrigation channel running the length of the field. The channel is positioned ...
A cross-sectional view of the wetting pattern provided by SSTI, as compared to drip irrigation. The systems rely on specific geotextiles to absorb the water from the drippers and to rapidly transport that water via mass flow and capillary action along the geotextile effectively turning those single drippers into billions of emitters.
Improving system design includes conversion from one form of irrigation to another (e.g. from furrow to drip irrigation) and also through small changes in the current system (for example changing flowrates and operating pressures). Irrigation management refers to the scheduling of irrigation events and decisions around how much water is applied.
Illustration of a pulse drip irrigation system. Magnets hold the valve closed while water comes in through the inlet and drip flow controller to charge the reservoir. When the building pressure finally overcomes the attractive force of the magnets the top set of magnets are forced upward to open the valve.
The irrigation system that provides the most control over water management, though conversely the most expensive to install, is drip irrigation. This system involved long plastic water supply lines that run down each row of vines in the vineyard with each individual grape vine having its own individual dripper.
Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
