The Effect of Soil Smoothing Devices on the Action of Pre-emergence Herbicides in Soybeans and Corn
Published online by Cambridge University Press: 12 June 2017
Extract
A review of literature indicates that there are considerable variations in the results obtained in using herbicides for selective pre-emergence weed control. These variable results have been attributed in part at least to a large number of possible factors, a few of which are: soil type, soil moisture, soil surface condition, rainfall, plant varietal difference, and application variations and errors. In 1952 a study of the literature reporting research studies and recommendations indicated that some method of rolling or smoothing prior to pre-emergence applications might prove to eliminate those variations in results from such applications as could be attributed to the rough, cloddy condition of the soil surface. This was particularly noticeable in early bulletins of the cotton producing states, a number of which (1, 3, 4, 6, and 7) recommended that the soil surface be rolled smooth prior to the application of pre-emergence herbicides for weed control in cotton.
