BROMINE IN GLASSHOUSE LETTUCE AS AFFECTED BY CHEMICAL SOIL DISINFECTANTS AND STEAM STERILIZATION |
| Authors: | J.P.N.L. Roorda van Eysinga, S.S. de Bes |
| Abstract:
A close relation exists between soil Br as determined by the 1:2 volume extract method and Br content of lettuce. Soil disinfection with methyl bromide strongly increases the bromide content of soils; metam-Na, methylisothiocyanate and dichloropropene were found to do so to a much lesser extent. Soil steaming also results in a raised Br level in soil and crop. Leaching the soil is an effective way of lowering the Br content. | |
