Furrow irrigation

Furrow irrigation consists of running water through a ditch 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 gradient of 1% so that the water runs smoothly and without causing erosion. In these systems, water runs slowly and infiltrates through grooves or small open channels regularly equidistant, in the direction of the greatest distance. It should be emphasized 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 throughout the plot. The ideal combination between 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 is achieved.
