When cropping is done by creating rows and furrows in the farm, then this furrow irrigation system is used, such that water is supplied or made to flow down the furrows and it seeps into the soil horizontally and vertically thereby filling the soil reservoir. This is an economical way of irrigation where the flow of water is controlled manually. The slope for the furrow irrigation should be around and 0.5%. For sandy soil, the recommended spacing of furrows is 30 cm (coarse sand) and 60 cm (fine sand). Similarly for clay soil type, the spacing between furrows should be around 75-150 cm.
What is furrow irrigation and what is the slope and spacing of the furrow system?
