there are heaps of other reasons, not the least of which is how much it improves the soil with the littlest possible effort on our part (e.g., we aren't spring chickens any more and if we can make it easier well that blast it all! why not!). it is an organic, healthy way to raise food which is dead easy and requires minimal effort .... how can you not give that a go!
in a nutshell, it is about building up rather than digging in. you use it as a base and foundation on the ground .... and build up, using only straw, leaves and mulch from there. how easy can that be!
this quote from Homestead.Org really put it in perspective from a Creation Care point of view.
... a gardening method that she claims, properly, was invented by God. For it was God who decreed that each year leaves would fall and cover the bare earth, and that in the spring, plants germinated and under their blanket of leaves would miraculously regenerate. From this and other simple observations, Ruth decided that everyone should do what God does, and cover their garden area with "permanent mulch." And then, as she had, they would discover that "There is peace in the garden. Peace and results."
we have used this several times now and have been amazed at the results. we were doing mandala gardens and let the chickens in their dome dig the soil and then we created our mandala's directly on top of that area. we got fabulous plant growth and super healthy soil.
most recently i used this with our potato bed. a 15 x 1 mtr bed full of potato's. we started with laying down a broadcast of winter green manures .... just to give it an extra leg up on fertility. but then we put it all under a bed of .... mulch. covered it. smothered it in fact.
after a chop and drop of the winter green manure, the next step was a little more labour intensive .... but by choice. we made pockets in the straw and filled these pockets with compost. into that we put our potato's. and let me be clear .... i dug those pockets with my hands .... so it's not as if it took a lot of work!
and then it was another thick layer of mulch (like 15 cm).
as the potato's started popping through, i hilled up around them .... just like you would with straight soil but rather than soil, i used, you guessed .... mulch. ones that were growing too long and spindly, i gently laid them down and put mulch right on top .... this would encourage growth from those points under the mulch and more 'taters! and who doesn't want more 'taters!
... it is not instantaneous. this method is about letting nature do it's thing. for potato's it is a snap. but using this method as a primary system will take a bit more time. perhaps adding compost between layers or chicken manure to help enrich the process as it breaks down and makes fabulous soil to grow your food in. you will start seeing results straight away .... but your best results will be after a few years.
we will be using this method for our entire veg patch as the season goes. as a season ends we'll throw down some green manure and cover the lot with straw and let the earth, worms and natural systems do their good work. it also means, btw .... no digging! no sore backs!
here are some pictures of what we've been doing with the potato's. a reference of some of my favorite ruth stout links is at the bottom. frankly tho, if you simply google Ruth Stout you'll find heaps of information.
|the green manure is coming on nicely!|
|Planting the seed potato in the hay in pockets of compost between|
the smaller green manure.
|mulching higher and higher!|
|laying the tall stems over gently and covering with mulch|
to assist in further spud development!
|another view on laying the stalk over and putting mulch over it.|
|gotta keep them mulched|
|one of the latest views. i wonder how many potato's|
we'll get from this harvest?
