Types Of Irrigation Systems Southern NH

By Stephanie Snyder


Drought is a major issue that affects crops in the field, and we have to think of how we can supplement water to them. Such is possible by flooding artificially by the help of pumps, pipes, and sprays and is done regularly at intervals. There are different kinds of irrigation systems southern NH used by farmers. They get water from rivers, lakes, reservoirs, harvested rainwater or underground. Landscapes are preserved, controlling weeds and raising field crops through irrigation. Consider the many different classes of these systems before selecting the one to use.

Water can be applied in the field and distributed over and across the surface. It flows by gravity uncontrolled. As it flows, it infiltrates into the soil for use by crops. This method can be classified into three; basin, furrow and border strip irrigation. At times the land has an overflow. Thus the system is also called flooding. Nevertheless, it also leads to deep drainage and water logging.

Putting water on the soil surface using pipes, tubing, valves, and emitters are called drip, micro or trickle. Water penetrates into the surface of the ground or to the plant roots directly by drops. It is possible to add inorganic fertilizers. Use of drip lines is preferred because it ensures water-efficiency due to reduced runoff and evaporation. It fits in both large-scale or small-scale farms. Despite this, a person with the ability to design, install and run the system is required, and soils can also clog the pipes.

Sprinkling is another way used. Pipes convey water into the field, and it falls like raindrops through the nozzles. This method can be used in different soil types and landscapes. It helps in preventing frost, soil and crop cooling, efficient and uniform. However, you have to cough some money to install and maintain.

Also, there is a type where pipes are used supported by the motion of towers that are fitted in a row and raised two to four meters high above the surface. It propels itself, and the pipe at the center supplies water, and the crops are watered as the towers are in motion. Thus it reduces tilling of land, and it is effective.

Use of manual watering cans and buckets. The system requires little infrastructure and technical equipment although it is labor intensive. It can only be done on a small piece of land. The land is irrigated where necessary. Thus, it helps in water conservation.

Irrigation can be done just below the ground level next to the plant roots, and the water is later absorbed. Areas where production of peppers, sugarcane, and tomatoes is carried out and have a higher table of water widely adopt this system. A workforce is not a major issue and watering is uniform promoting healthy crop development.

Lateral move irrigation is carried out by fixing a wheel and sprinkler heads on the pipes which apply water over and across the field. You do not require a lot of capital to start it but workforce for changing pipes is crucial and the major drawback of this method.
