Decarbonise the air, recarbonise the soil!
In reference to last week’s episode #206 Two Different No Dig Garden Systems, I called for any listeners who understood the carbon drawdown effects of lasagna gardening structures I was talking about. A big thank you to Peter McCarthy for his response.
As far as your question about how the lasagna system works as regard nitrogen drawdown (which is a concept I don’t believe is a long term problem in any case assuming u have a complex biodiverse system that is going towards abundance 😉). My observations are that with this system when freshly layed and planted IE the layers have not yet become good soil, is that the plants roots can find the nutrient throughout the layers as the plant needs them. The fresh chicken manure that when fresh would ‘normally’ burn roots, doesn’t in the lasagna system since the roots 5 cm above are nitrogen deprived in the straw/leaf layer. The plant can pick, choose and adjust the soil environment. This is a hypothesis based on observation not proven by science. We as humans don’t have to understand the mechanisms… It makes us feel stupid but often plants know best. Lasagna beds work a treat. And have the bonus of training the stupid human to continue adding simple layers on top and avoiding our temptation to dig it over.
