Healthy soil and sustainable growing

[richard green <greenrw71@hotmail.com>]

I've also been pondering what to do in case of a shortage. I feel I should be more self sufficient in my garden. Several old times books used sulfuric acid and dissolved bones...cattle,pig,ect... I dont make sulfuric and am leery of the consequences soil wise of using it ,however diluted... Vinegar also I've read can dissolved bones? Any thoughts along these lines? I am no chemist!!!

> Two Australian experts in global phosphorus have warned instability in the Middle East and North Africa could threaten world food security, due to the high proportion of global phosphate rock reserves in the region. Speaking in the US today at the Sustainable Phosphorus Summit at Arizona State University, Professor Stuart White and Dr Dana Cordell voiced concern that the instability is an additional component in a looming supply-demand gap in global phosphorus resources.
> Phosphorus is required to produce fertiliser and is not able to be substituted in food production.
> "Morocco alone controls the vast majority of the world's remaining high quality phosphate rock," Professor White said. "Even a temporary disruption to the supply of phosphate on the world market can have serious ramifications for nations' food security."
> Professor White and Dr Cordell, from the Institute for Sustainable Futures at the University of Technology, Sydney, are leading an international research initiative on the likely peak in phosphate rock production before the end of the century. "Demand for phosphorus is increasing globally due to changing diets in developing countries, biofuel production and population growth," Professor White said.
> "Peak phosphorus is often highly misunderstood as the 'year we will run out of phosphorus'. The peak actually refers to the point in time when production will no longer be able to keep up with demand due to economic and energy constraints. Whilst the exact timeline is uncertain, it will be much sooner than the time when all the reserves have been depleted. "Even before the peak in production occurs, there is the prospect of significant price spikes and impact on farmers and global crop yields."
