Which of the following most accurately describes the problem?

Rothamsted experimental station disproves the objection to rotary power agrimotors that rotary cultivation gives too fine a tiIth, in its records for 1934, which have just been issued. It finds that the filth produced by rotary cultivator is no finer than that obtained by ordinary implements. It is, however, much looser, and the methods for dealing with this new condition are still being worked out.

It is stated that in early stages of plant growth a rotary cultivation has been found superior to the ordinary type; germination and early growth are both better. "If technical difficulties of rotary cultivation can be overcome," says one report. "the way should be clear for an appreciable reduction in the heavy costs that the arable farm must face."

Effects of different methods of cultivation formed one of the studies. It is found that the kind of tilth produced by spring ploughing or cultivation is much more controlled by the weather of the previous winter than by spring treatment—which for power farmers means getting as much ploughing and cultivating as possible done in the autumn and winter.
