4.10.2 Muddy Soil Conditions

4.10.3 Operating Curves & Corners

Seeding depth may be altered if mud sticks to the packer tire. If mud is only 1/4

in.-3/8 in. (6-10mm) thick, then this is not usually a concern. Assuming good soil

moisture, the reduced seed depth is still adequate. If the mud thickness is uni-

form, the seed depth, also, will be uniform, but shallower than the initial depth

setting.

It may be desirable to set the seed depth deeper to compensate for mud build

up.

When seeding around curves and corners the packer wheel moves out of the

furrow and rides up on the hard, undisturbed furrow shoulders. Packing force

is concentrated more so on the shoulder and the packing on the seedbed is

reduced. In addition to reduced packing action, fertilizer placement is also ad-

versely affected. Optimum performance, of course, is seeding in a straight path

as much as possible. It is also important to turn right as much as possible to

keep the fertilizer out of the seed row. When turning, the conguration of the

fertilizer sideband is less to cause seed burn when turning in a right-hand arc.
