Extract

Work conducted in recent years with volatile herbicides has shown that many of these materials give extremely variable results when sprayed on the soil surface but are fairly consistent when incorporated in the soil. Methods of determining distribution and placement of these materials in soil are generally tedious and often complicated due to a number of factors, including volatilization and leaching. Substitution of a fluorescent material for the herbicide in the application equipment offers a useful method of studying placement and distribution of sprays in the soil.
