The characteristics and performance of a modified stairstep, nutrient solution recycling, apparatus are described. An experiment in which the allelopathic potential of Agropyron repens was examined showed the apparatus to be reliable and accurate in operation. Allelopathic activity by A. repens was confirmed. The apparatus is also suited to studies of phytochemicals produced in stubble retention reduced tillage systems, in green manuring and in cognate areas.
