Water balance and distribution in the soil on maize in southern Chile

A water balance on maize in a Dystrandept was determinated. With raingauges and stemflow rings the amount of rainfall was divided into throughfall, stemflow and interception. The variation in time of the water content in the soil was determinated by tensiometers and gypsum-blokes located in the soil...

Summary:A water balance on maize in a Dystrandept was determinated. With raingauges and stemflow rings the amount of rainfall was divided into throughfall, stemflow and interception. The variation in time of the water content in the soil was determinated by tensiometers and gypsum-blokes located in the soil on and between plant rows. The water distribution on the soil surface was very heterogeneously determined by the plants development. The stemflow increased with plants growth and it is the principal factor of the irregular distribution of water in the soil profile. On the plant rows and up to a medium soil depth the matrix potential was greater than between rows. Small precipitations only have a significant effectiveness on the soil because of stemflow
