Developments in the field of agriculture have brought in tremendous changes in the irrigation systems. Also people are interested in adopting special ways to cater to all the irrigation needs of crops. Irrigation plays a major role in development of crops. The quality of crops can be influenced upon by the amount of watering that is obtained. The field generally has widened area over which irrigation seems to have certain practical obstacles. These practical hindrances can be overcome by adopting furrow irrigation. This is type of irrigation largely depends on the overall topography of the land.
Furrow irrigation is a unique variety of irrigation that is employed at varying contours of field. Parallel channels that are dug divide the field. The channels are utilized to mobilize the water that is sent from one end of furrow. Also one can be sure about the application of furrow irrigation in specific cultivation methods. For tree irrigation one can adopt furrow. Furrows can be dug in different manner. Based on the furrows plan, one can plant crops so as to get maximum output. Certain crops such as maize require constant supply of water through its growth phase. This is greatly satisfied by furrow irrigation technique.
Requirement of furrow irrigation
There are certain implied requirements that are to be fulfilled by the cultivable land in order to impose furrows over the land surface.
Mild slopes are required in order to facilitate better conveyance of water throughout the channel. This slope should also assist drainage of excess water during rainy days. These slopes should accommodate the surface run off. Steep topography prompts cultivators to use terraces and along these the furrows are built.
- Soil requirement:
Presence of sand type of soil can make inflow rate to slow down heavily. The rate of infiltration varies from one type of soil to another enabling the change in the type of furrows dug. Also clay soils tend to have totally different furrows when compared to other soils thus slowing down the travel of water.
Furrow irrigation provides ample opportunity for the crops to get adequate supply of water. The efficiency of the irrigation system can be increased substantially rendering proper vegetation growth. Furrow irrigations help use of contour of land to channel water to the crops efficiently. The inflow rate can be limited based on the distance of furrows made over the cultivable land. It is suited for cultivation of cotton and maize.
