Nitrogen uptake by rice plants from a dry soil at maintained water supply from a greater depth.

Abstract

In a pot trial in the Netherlands with sunflower and an upland rice cv., multiple-compartment systems with N and water supplied from different compartments were used to demonstrate that plant availability of N from a dry soil horizon was low. The separation of N and water in different soil horizons along with a decreasing input of irrigation water reduced the uptake of N more than the plant DM production was reduced by the decrease in the amount of water supplied to the plants.
