Understanding NPK in your organic garden

I thought some keen organic gardeners in this group may be interested in this article which I feel demystifies how to work through organic and biodynamic practices to integrate NPK - nitrogen (N), phosphorous (P) and potassium (K) into their food gardens without the need to rely on NPK fertilisers that are commonly used by industrialised agriculture and at times, passed off as "organic".

Good to know some of these little wrinkles which make all the difference. You're a bit far away for us really and mostly though, we're too decrepit to stand around for any length of time. I've read up some on BD and would like more specifics like you've mentioned but doing a course is just not an option for us.

Thanks Elaine. Its a very interesting area to work with and in particular working with the BD preps selectively  to enhance natural processes in plants and soil. You can also work with the preps to enhance planetary influences, for example, BD501 (silica) enhances the planetary influences relating to flowering and fruiting processes in plants and improves sweetness of fruit. I recently put out BD501 on my strawberry bed which has been cropping since June. Within days I got a whole new rush of flowers and its fruiting abundantly still. I expect we will have fruit until Christmas. With this rain the fruits are fattening beautifully. I work with these types of practical applications of Biodynamic methods in our courses. I have a 2 day course this weekend and two spaces left.
