Why is no till or growing in
smart pots/cloth pots with a premium soil brand so much more popular on larger commercial manufacturer farms than tilling?
There are a few factors here.
1. A lot of growers developed systems in soilless media that they scaled up to commercial scales rather than reinvent the wheel, so to speak.
2. Many startups might see the cost of a tractor and tillage equipment as prohibitively expensive, and opt for pots and soilless media which appear less expensive in the short term.
3. Most of the outdoor commercial grows are in warm, dry climates where tillage is less important. Tillage is useful for raising soil temps in the spring in cool climates and is necessary for making raised beds that are super important in wet climates. In Colorado all of the outdoor farms I've seen use raised beds to warm the soil prior to planting and during early stages of plant growth. In the wet eastern US, raised beds are critical to avoid heavy losses, if not a complete crop failure, from heavy rains.
Tilling generally works the soil about 6-10 inches deep. Your cannabis will appear to be doing fine, with the roots able to extend horizontally.
then, most likely, the hot, dry summer months (here, end of July and all of August) will fry all the roots because they are just under the surface. Combined with a massive leaf mass sucking water from the roots the plants don’t stand a chance.
Deep holes with deep watering to keep the roots down works for me...several 100 f days and I don’t need to change the water schedule (hardly, lol.)
Making raised beds will push that to 8-15 inches deep by pushing the tilled soil between the beds up onto the beds.
But soil is actually deeper than that, it's just that most conventional tillage equipment (ploughs, tillers, etc) leave a hardpan at the bottom that is difficult if not impossible for plant roots to penetrate. Using conservation tillage equipment like an
articulating spader will not leave a hardpan, allowing those roots to extend into the subsoil for water.
i run no till commercially. I hand tilled using man power 7 acres this year.
So you use hand tillage or no till? It's really not clear from your post.
Some people call the method of making holes with an auger and planting plants in them "no till" but that auger makes the equivalent of a hardpan on everything it touches. Instead of a hardpan 6-10 inches down you've got one that's 10 inches deep and 12 inches in diameter.
Real no-till systems are either reliant on herbicides that are not currently registered for use on Cannabis or use more complex [organic] cover crop/crimper/mulch systems that come with a steep learning curve and are not suitable for areas infested with tall perennial weeds. Furthermore, no-till Cannabis systems are risky in climates that are wet during any point in the crop's life cycle with most soils. Heavy rains can leave soils waterlogged and wipe out an entire crop.
