Farmers get attached to their soil for good reason. No soil, no business. They have to treat it right, and there are lots of groups and movements telling them so. They may be overstating their case, however, if farmers are starting to feel guilty, defensive or ashamed whenever they pick up a shovel or fire up the tiller.

Quick question for ya’ll …
I grow arugula here on Maui as you know. You also know it’s essentially a quick crop to grow. I plant it in sections at different times, so I always have available product for sale. My question is with regards to overtilling. After each harvest, every 6 to 7 weeks, I till the area (depth of 5″ +/- inches, composting old plant into soil) and reseed for the next crop. I’ve been reading about the issues of soil disturbance in doing so, but how is this to be avoided? Mahalo for your thoughts.
Agriculture disturbs the soil, always has and always will. You can’t plant without some type of soil disturbance. If you think rototilling is too harmful to the soil, you can pull the spent plants by hand instead of tilling in. Then you can use a hand tool, such as a three pronged cultivator, to bed prep. Then rake the bed, so it is level. So using hand tools, even on acre-size plots is do-able, if you feel the trade-off in time and effort is worth it.
If the question relates to a decrease in productivity, you should consult with a soil expert. But most often it stems from a philosophical concern. Wally has been cropping some of his backyard plots with a tiller for over 20 years and the soil remains healthy and productive. He loses no sleep over soil disturbance.
If the thought of working the soil disturbs you, you might want to consider a different line of work.
