Summary: The distribution of trifluralin in soil was measured following its incorporation with the rotavator, rotary power harrow, reciprocating harrow, spring‐tined harrow, tandem disc cultivator and drag harrow. A single pass with the rotavator gave an even distribution In the top 5 cm of soil and similar results were obtained by cross cultivations with the rotary power harrow, reciprocating harrow, spring‐tined harrow and disc cultivator. A single cultivation with the spring‐tined harrow, reciprocating harrow and rotary power harrow left much of the herbicide close to the soil surface as did both a single and cross cultivation with the drag harrow. With the tandem discs, although a single pass did incorporate the herbicide, a cross cultivation was necessary to ensure that incorporation was even enough across the treated area. A single pass of the rotavator gave a uniform mixing throughout its working depth, whereas cross cultivations with each of the other implements gave a relatively uniform mixing to about half of their working depth.
