First year 1/4acre garden set up, spring 2013 French intensive soil prep(2foot deep trenches dug into each other). Desert sandy loam, no fertilizer, just to see what I had in soil quality and get a feel for my new digs.
Plants did ok but soil needed a lot of work.
Planted rye, alfalfa, and white clover to build tilth and boost microbes. Left fallow for 2 years and watering and fertilizing to keep things cooking.
I tried a grow last year and lost everything midsummer to the neighbors weed killer overspray,
24d left everything stunted in suspended animation so I pulled it all and scrapped the top inch of top soil.
The neighbor has been dealt with.
Ran another cover crop combo and watered heavily
Chopped it all last month and mulched it into the top 3 inches
this spring were expanding to 1 full acre and bringing a load of organic alfalfa hay and chicken manure for mulching into those new rows.
After the French intensive no further tilling is allowed, just compost layering and the occasional fluff with a broadfork.
Only complaint I have with desert soil is the microbe and insect life. Brutal murderous little monsters. Watched cutworms saw through 2 inch wide corn stalks. Predator wasps, lizards and desert mantis keep things balanced though.
