Furrow irrigation

Furrow irrigation consists of making water flow through a trench or furrow to the entire plot; the water reaches the roots of the crops, entering towards the sides and towards the bottom of the irrigation furrow. The furrows are made in a V shape with a depth of 15-20 centimeters and 25 to 30 cm wide at the top and with a slope of 1% so that the water runs without difficulty and without causing erosion. In these systems, the water flows slowly and infiltrates through the furrows or small open channels regularly equidistant, in the direction of the greatest distance. It is important to emphasize that the furrows must have a gentle and uniform slope and be fed by small flows so that most of the water that runs through them infiltrates uniformly along the plot. The ideal combination of flow, length and slope of the furrow must be sought so that, under the dominant conditions of the soil infiltration rate, such maximum and uniform infiltration occurs.
