Article “WaterMovement” by W.H. GARDNER (1962) – How water moves in the soil
Six pages of photographs reveal the great diversity in one of the most commonplace phenomena in agriculture.
Article “The irrigator, the wet bulb and the advisor” by Xavier Eftimakis
The quantity of water received by the soil at dripping point, during a simple irrigation process is greater than the natural rainfall for an entire year. How does the soil manage this uncanny and repeated phenomenon ?
