Please explain that last part about irigation being carbon delivery? like silt and other biomass?
Its very slow starting up from a plowed dead land in these types of climates. Thats why I prioritize the earthworks.
All I am growing now is on a land that doesnt capture water. Sometimes it feels like I will have to start from 0 after earthworks, moving all that "top soil". I wont be able to put it aside since its too little. But after those earthworks, there will be much much more standing water after rains.
