Influence of soil surface structure on infiltration and subsequent evaporation under simulated laboratory conditions

The improvement of the aggregate stability of a 2 cm deep surface layer, resulting from treatment with a polyurea soil conditioner, increased the water infiltration during simulated rainfall by 94% and also substantially reduced evaporation rates. At potential evaporation rates of 15, 10 and 5 mm da...

Description
Summary:The improvement of the aggregate stability of a 2 cm deep surface layer, resulting from treatment with a polyurea soil conditioner, increased the water infiltration during simulated rainfall by 94% and also substantially reduced evaporation rates. At potential evaporation rates of 15, 10 and 5 mm day −1, respectively, the total mean water loss under the untreated surface layer was about 47%, 37% and 30% and under the treated surface only 26%, 15% and 11% of the amount of infiltrated water.
