Humedecimiento con goteros de 4 y 8 L/h sobre canteros en suelos ferralíticos rojos compactados.

The results of the observation carried out in relation to the wetting achieved with drips of 4 and 8 l/h when it is used in beds shaped on Red Ferralitic Compacted soil with amounts of water of 4, 8, 12 and 16 L. For rising the humid bulbs, Soil samples were taking every 10 cm horizontal and vertically 24 h after irrigation, using the gravimetric method to determine moisture. It was observed a tendency in bulbs to stay opened in this phase, due to soil compactness at depths higher than 40 cm, with humid length of 30 cm that increased as the amount Of water applied increased, getting to maximum levels of 44,1 and 65,9 cm respectively.
