520			_aAn efficient method of routinely measuring soil water content in containers,of calculating and recording the volume of water required to bring them to a specified water content, and of accurately adding the calculated soil water volume to each container is described. The method, which requires use of a computer, a balance weighing to 0.1 g, and a burette (graduated in 1.0 cm3 divisions) with reservoir, is a rapid (o 3 h for 150 containers), accurate (o ñ1.0 cm3) means of monitoring and maintaining soil water content and of estimating and recording evapotranspiration in greenhouse containers.
