Groups Of Irrigation Systems Southern NH

By Stephanie Snyder


Crops undergo stress during the drought season or when rainfall is unevenly distributed and to sustain their growth water is applied artificially through sprays, pumps, and pipes. It is usually done constantly or at intervals. To support this, farmers have adopted irrigation systems Southern NH. There are many sources of irrigation water which may include; harvested rainwater, underground or even the surface through reservoirs, rivers, and lakes. Irrigating controls weeds, crop production and preserving landscapes. Before choosing the system farmers should know the different ones that exist.

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.

Farmers supply water to crops using tubing, emitters, pipes, and valves. It trickles and infiltrates into the soil and to the plant roots. Fertilizers are provided in solution form through this method. It enhances the maximum use of the available water because less water is lost through evaporation and runoff. Farmers with small or large land sizes can practice it though it has some drawbacks; sensitivity to clogging and high-skilled labor is required to operate.

Use of overhead sprinklers is used where water is conveyed through pipes and under high pressure it is applied on the land like the rain. As the water drops it cools the soil and crops protecting them from frost, also it ii efficient and uniform. The system can be implemented on various land terrains and soil types. However, huge capital to initiate is used.

Center pivot irrigation has also been widely adopted. One pipe is held up by some mobile towers in a row and is placed above the ground two to four meters. It is self-driven, and the water in the middle pipe is supplied as the towers slowly rotate in motion. Nozzles are also fixed on the pipes and as they move around the land is irrigated. Therefore, it is efficient and reduces tilling operations.

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.

As mentioned earlier, you direct the water below the soil surface at the root area where upward absorption later occurs for growth. It has been widely embraced in places with a raised water table where sugarcane, peppers, and tomatoes are grown. Less labor is required, strong plant growth and irrigating is uniform.

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.
