i wrote this before i saw salamanders post so it overlaps a bit.
If you want the nutrients to grow a lot of food from a crops, or you keep animals or buy manure or you buy chemical manure while if you have nitrogen producing plants and a few animals both of which increase the nutrients on the
land you wont need to buy in nutrients you need to follow all his ideas if you are goin gto v¡avoid the use of chemical fetrilisers or bought manure.
I suppose that bill mollisons way is a quicker, safer and cheaper way to get land working than others if you do al the things he suggests. If i left my land to weeds to better the soil as i did the soil did got better, that is in fifteen years but maybe, had i known and followed all bill mollisons ideas or his ideas and huglkulture, then my soil would have got better that much faster all his ideas being the hens and dcuks and nitrogen fixing plants increasing the nutrients in the soil faster. If people are hungry telling them how to get their land into high productivity fast is important. if they are weekenders like me not so much.
Maybe with nitrogen producing
trees as well as clover and other nitrogen fixing ground plants, you would you would get much more organic matter to better your soil sooner because as well as the ground plants
roots and leaves bettering soils you would have the leaf fall of the trees to add organic matter and if the trees grew quicker because of the help to the soil from hens and ducks do there, leaf fall would be even bigger. I suppose you need to plant more plants at first than you will need when they grow for maximum leaf ftall production.
Organic matter improves the texture of the soil, it makes the soil airey warm and good at taking up and retaining more
water and the whole
bill mollison design would make more organic matter sooner than it was produced in my garden, i imagine, so it would be worth following al his directives on this account. The truth is my only nitrogen fixing tree one i grew from seed on my balcony and treated rather roughly, moved to the garden has hardly grown at all. I hardly watered it in the heat to help it get through the first summer till it established good roots though. Organic matter that is your texture of the soil improving factor, so roots can move more easily through the soil and get less cold and water logged. your water and air holding capacity. Mineral particles separated by organic matter means more space between mineral particles for air which is important for roots, as well as more organic material to soak up water like a dish cloth.
The whole Mollison way should allow your soil to get better fast and without spending on fertilisers and i bought some bags of horse manure last year for my soft fruit and i decided a nitrogen fixing tree would be so much cheaper, only a bit more expensive than a sack of horse manure if you look around and buy cheap ones, smaller ones, and the trees would with any luck last for ever.
A determination to show how people with very little funds can do it is one motive for following mollison directives and giving a good example and another is to show farmers they dont have to buy expensive chemicals, they couldd relie on a healthy soil.
Mixed crops also helps keep illness aways and so reduce pesticide bills, and be puttign less poison in the atmosphere. I read an article that said that because of herbicides and pesticides th ecountry wa sa more polluted place than towns are.
I don't think Bill Mollisons ideas are so important for people who have plenty of food and dont need the fastest road to plentiful production in a small space as maybe some out of work people do need now. also people who dont live in climates where the balance between good and bad soil is so easily tipped, like deserts or near deserts dont need to take all bits of permaculture so seriously from day one. Soil can get spoilt everywhere and does.
When i think of someone going out to make a go of things in a desert and see that they hope just one bit of permaculture will serve them, when it seems that they are not going to immediately implement all of the bits of the design, which should just roll once started, then i get scared for those people, the idea of them making a go of it in the desert even if they are going to put all bits into play still scares me for them. agri rose macaskie.
