Great article. Organic growers replenish the soil using compost made from the by products of what they produce, the plant material that we don't eat, such as leaves and stems. They do use organic manure from organically raised livestock which is why there is a shortage of it, there are not enough organic livestock producers. They also use nutrients from the sea to help replenish their soil. They do not user synthetic fertelizers which only add 3 nutrients to the soil, not enough to sustain the soil over a period of several years.
Another method of organic growers is to plant "nitrogen fixers" such as legumes. The roots from these plants produce nitrogen to help support the soil, another method of organic farmers is to plant rye or other grasses then tilling it under before it matures to add nutrients back into the soil.
Every organic farmer that I know, including myself, has a compost pile. Discarded plant material and organic manure are left to decompose and used as fertalizer in fields and gardens.
If you do your homework you will find that the great dust bowl of the early 1900s during the great depression was not caused intierly by drought, it was caused,in part, by the destruction of the top soil. There were not enough nutrients to support any crops, not even weeds which would have at least held the soil in place. Our native soil is so depleated that it's a wonder it supports anything.
Organic growers support the soil, not just the crops they grow. They know that if they want to continue to produce healthy crops, they have to take care of the soil too. And by not using pesticides they protect the environment. They don't kill the bees and butterflys which polinate the crops. Pestecides are non selective thay kill everything, including people, why do you think there are warning lables on all pestecides and the poison control center phone number included on the packaging?
We are what we eat and I choose to eat as healthy as possible, I choose not to eat poison or synthetic foods if I can help it.
