Look seriously at the number and quality of the moving parts on the drills you consider!
Weaving uses very few bearings and in stead teflon bushings. They are very easy to change and they last very long time, and there are little maintenance to do. When I look at some of the others on the...
And here about the Australian results from Kirkby & Kierkegaard: SOM and nutrients
Found thesein english about nitrogen and protein levels in wheat in Denmark:
Generally too little rotation. Pig producers are generally very conservative with tillage and have focus on WW to get most feed for the pigs. But regulations demanding 14% of rotation area with cover crops force to more spring crops. And now is there even higher demands demands for cover crops...
In this country DK have we lost >3 tons CO2/ha/y on the best soils during nitrogen restirctions for 25 years where it ended with 137 kg N/ha for winter wheat after OSR!! Nobody would buy danish wheat. Pig producers bought German wheat while danish wheat was for feeding goats or camels!
Sequestring 1 t/ha Carbon need 92 kg N/ha.
This is why No-till in my opinion need much more N (could for some part come from legume cover crops)
Still waiting for real sceintific results showing that fertilizer is not needed while buttom line is the same or better.
Many snake-oil sellers is on...
My experinces with tine drills is that they can make problems also. Because of soil flow, straw and soil can land on top of the seed row and cover the seed so germination is reduced or does not happen.
So if I generally drill in 4 cm depth, then some places there will be thrown 2-3-4 cm soil...
Very rare at no-till, but in cultivated soil it happens. Here is extremely many flint stones and after only 1100 ha discs has to be renewed.
But it means nothing, because less work (salary here is typically >27£/hour) with stones and saved money by no-till makes it worth.
Depending of the amount of stones!
And the drought here has really been reducing the radius.
But I have now 1100 ha on the counter, and its near time for change for a 6m. Has changed quite some bearings.
In my tine seeder time the wear could be 3x higher here on my stony soil than other places...
What are your experiences with long stubble and raking?
I see that raking has some important influence on controlling slugs, but will it create problems if stubble is very high. I guess it will block the rake in many situations?
On the other side: with long stubble there will be less straw on...
