EXPERIMENT

Broadcast sowing into cover crops

Farming large areas with horses requires constantly searching for economies of power. To that end, I wondered if instead of rolling a vetch cover and sowing through the mulch with a heavy no till drill, would it possible to sow the cash crop broadcast then roll the vetch down on top of it, effectively placing the seed between the soil and the mulch where it should be able to find enough moisture to germinate.


I tried this with Buckwheat which was sown into a cover of vetch / crimson clover.

The GPS regulates the seed flow following changes in speed. In the wooden box is a battery. It took some time to match the power requirements of the seeder, meaning a few gaps in the field this time around.

After rolling

Germinating buckwheat, dying vetch.

The yields in this field (1.75T/Ha) exceeded those of the buckwheat sown into a prepared seed bed next door. Sowing broadcast, we were covering 1.25Ha an hour with the horses.
