Yes, compost, no-till, etc. You can't put the worms & microbes there, but if you build it they will come. Soil with a higher organic matter content & microbe population absorbs & retains moisture better than "dead" soil with low organic matter & no microbes, and plants can develop deeper roots which lets you water long, deep, & infrequently which reduces evaporation & runoff.



I read somewhere recently that fixing the deficit of carbon in agricultural land world-wide would actually require more carbon than has been added to the atmosphere through fossil fuel use. Getting all those farmers to do it, however, would be difficult.
