So true. My compost bin says so.
We farm in zone 9a, compost huge piles from our fields and free organic matter from tree chipping companies.
We plant cover crops in rotation which also builds soil and adds nutrients.
Our greenhouses (like most) produce 4-5 times compared to open field growing.
One 3000 sf greenhouse is now equipped with water source / radiant heat coils buried in the soil for heated seedbeds, not just for germination but continuous growing.
Increased heat = increased microbial action = stronger plants, more fruit and better quality.
Heated seedbeds alone can increase production 200-400%
Couple that with growing in a green house and your production is increased 4-5 times and the outcome can then be 8 to 20 times the production as open field growing per acre.
Much loss and degradation of top soil is from poor farming practices, over production, little investment back into the soil and other factors common to big ag operations.
There are many Solutions to these problems depending on where you live and what you have for space (even small spaces).
While big Farma and big guv do their thing, markets for smaller operations can turn hobby’s into food,fun and $$$.
Problems are often opportunities.
I have plenty of free horse manure for anyone who wants to transport it themselves.
