I would like to get my veggie garden soil tested for all nutrients. I’m good at growing a stupid amount of veggies (about 200 Kilos a year) but I know I am missing some nutrients, not getting replaced with the organic matter I feed it. For instance, I have to use potash on the tomatoes or else they don’t fruit and just grow into a big bush. I’m concerned that continued use of this product will create excess salt and render the veggie patch in a bad state.
I have done a little research and the SWEP Analytical Laboratories (http://www.swep.com.au) appear to do a good job but they are in Nobel Park Victoria. They analyse your soil for its nutrient contents and recommend what basic minerals you apply (not chemical fertilisers). Is there anywhere in Canberra that can do a similar soil test and provide good value for money? Has anyone used SWEP and can recommend them? Does anyone know what minerals Canberra soils traditionally lack (besides organic matter)?
