The influence of soil steaming on some properties of the soil and on the growth and heading of winter glasshouse lettuce. II. The reaction of the crop.

Abstract

Soil steaming increased fresh and dry weights and N and Mn contents of the plants. Leaching the steamed soil caused a further increase in Mn content but decreased yields and N content. The addition of straw to the steamed soil did not affect growth or N content but it reduced the Mn content. Plants grown on steamed soil had darker coloured leaves and a greater incidence of leaf margin necrosis and bad heading than plants grown on unsteamed soil. See also Sous Fertil. 33 [1230].
