Abstract

A technique of collecting contiguous soil samples was developed that showed the distribution of nitralin [4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline] in the soil profile. About 60 days after the herbicide was applied and incorporated with a disk harrow, the soil was sampled from two sites in 1968, five sites in 1969, and five sites in 1970. Bioassays, that utilized root lengths of grain sorghum [Sorghum bicolor (L.) Moench ‘Dekalb 57E’], indicated large variation in herbicide concentrations among adjacent or on contiguous soil samples.
