Double Digging
Having done my share of double digging... I would like to know if anyone else does this on a larger scale basis. Say an acre or more. Is it practical on a larger scale? If so how? Thanks Dale |

On that large a scale, I think you plow with specialized rigs. Rippers, large discs, moldboards, subsoilers... http://clic.cses.vt.edu/icomanth/soilmodi.html Having double dug one flower bed (for a friend) two years ago in the worst sort of compacted clay soil, I could not imagine doing it for acre+ plots without a small army of people who were desperate for work (ANY sort of work) and plenty of money. -- Pat in Plymouth MI ('someplace.net' is comcast) Any technology distinguishable from magic is insufficiently advanced.

Thanks Dale Even when done by machine, the soil eventually recompacts if you don't add organic matter - or at least that is my experience. And if you do add it, and it is brown, it will reduce N. If it is green, it will disappear quickly. What improves the soil permanently is patience and the usage of mulch and crops that break the ground or otherwise help a large earthworm population. A dandelion taproot can go down five feet, and the first foot of that channel probably remains open one year in heavy clay (I am guessing. My parents have heavy clay and I have seen channels in their soil). If I were to try loosening one acre of clay I would probably start by getting a few loads of free woodchips or leaves from the utilities, and spread it six inches thick in the fall. I would maybe mix in grass clippings on part of the area to see whether that helps (not for nutrients but to speed decay and feed earthworms. They need nitrogen too). Next I would make sure that there are earthworms every few feet or so to speed colonization (they don't migrate much by themselves, and if the soil was degraded they would not be there). In the spring (or summer if the mulch is still too heavy) I would try a variety of crops that are known to help break the ground: clover or other green manure, mache, chicory, potatoes, you name it, and see what works best. The next year I would use what worked best, and perhaps start adding nutrient-rich matter, such as manure. One would still have to occasionally plant a cover crop to keep the soil loose. |
