Generally, crop irrigation involves controlled use of water for agricultural purposes through the artificial mechanisms. It is one of the crucial practices in the world since it promotes production of foodstuff. It is also a dynamic program that encompasses several techniques. The common techniques include; traveling gun, rip, rotation, gravity, sprinkler, sub-irrigation, furrow, flood, center-pivot, and supplemental among others. Therefore if a farmer within Tucson irrigation techniques like these can be really useful.

Center-pivot, for instance, is an automated sprinkler method that involves an automatically rotating the sprinkler pipe. Water is transferred to the sprinkler nozzles from the center point of the field to be irrigated. Water is usually delivered to the center of the system before sprinkling to the crops or land. In case of crop irrigation, the pipe is supported above the crop at fixed spacing and rotated by mechanical, hydraulic, pneumatic or electric power on skids or wheels.

Drip method on the other hand is a planned system which allows direct application of water to the root zone of the plant. In this technique, water is applied with the aid of applicators such as emitters, porous tubing, perforated pipes, orifices, and many more. Application of water is done under low pressure with the applicators placed either on or below the surface of the ground. In flood method, water is applied on the entire surface of the soil.

Furrow technique is similar to flood method in that they require a lot of water for use, except that furrow allows partial flow of water through the dug rows. In gravity method, water is allowed to flow by the force of gravity. Rotation type on the other hand involves filling the irrigators with allotted water which is then delivered to the crops or field at certain intervals.

Irrigation is a dynamic practice and involves the use of a wide range of tools for several purposes. Some of the techniques are only special to certain methods, while some are just used for the general duties. Some of the basic tools used are; wire cutters, shovels, wrenches, knives, and hacksaws. There are also other tools that are only specialized for certain duties.

Some of the special tools include; the round and square pointed blade shovels, trenching spade, mattock, tamper bar, broom, landscape rake, work gloves, latex gloves, pipe wrench, measurement tape, riser extractor, hacksaw, wire cutter, screw drivers, sledge hammers, trencher machine, and many more. These tools are used for specific and general operations of installation. The point blades hovel in this case is used for digging larger holes for valves, multiple pipes, and many other duties.

Trenching spade is suitable for removal of dirt from trenches. Additionally, mattock is used for removal of rocks and digging short trenches. Since it has a nail-like head, the tamper bar is suitable for making soil compacts.

Landscape rakes are normally used for shaping the ground before planting. Just as the name suggests, PVC pipe cutter is used for cutting PVC pipes. Work and latex gloves are used to prevent blisters and keeping PVC cement from the hands, respectively. If living in Tucson irrigation tools like these can be found from the major stores in the region.
