After waiting 18 months, we finally had a GP 3PT no till drill delivered. We opted for the extra small seed box. It took some trial and error to find the sweet spot for the right amount of depth and compaction. What works well for our dry plots tends to tear things up a bit in plots with more moisture.
I rationalized the purchase based on the time it would save, and hopefully lessen the area of solid disturbance so as to decrease the scourge of quick weed.
It did a great job of drilling brassicas into crimped buckwheat. It’s also done a good job of drilling brassicas into overgrazed beans. Once I got the adjustments set right, it’s also been great at planting rye into existing clover or newly killed plots (we used the small seed box to simultaneously plant the clover). While the grain has germinated as expected, it’s been harder to track the germination of the clover. It’s been so dry that the clover germination may be at risk.
The real test will be next spring’s planting of beans.
As I’ve contemplated success to date, there’s no question about significant time being saved. I’m still trying to figure out the best way to get fertilizer into the root system. Given our dry conditions this year, I’m not sure the rains have done what they normally would. It is my hope that in time, fewer soil amendments will be required.
One challenge I’m still trying to figure out is how minimize clover seed coating from gumming up the small seed mechanism. It tends to build up and has even bridged through the tubes. I’d welcome any thoughts on cleaning this up and minimizing the problem in the future.
