Methods for Organic Farmers and Growers

There are two main questions people have asked about this chapter: 'Why should soil analyses for organic farming differ from those for conventional farming?' and 'How can you get the details of methods and interpretation of results when little has been published, and there is so much secrecy because of vested commercial interests?' The former query is easier to tackle than the latter. It will be seen that the organic approach to soil chemical analysis looks at nutrient balance and potential availability over a longer term, rather than the immediate availability of nutrients. The commercial laboratory of Dr Friedrich M. Balzer has kindly provided some details of his designated methods, with corresponding guidelines on interpretation of results indicated on their website. More detailed information from commercial laboratories on interpretation, particularly from those using the Albrecht approach, would be desirable.
