Is this the only Queensland rock dust brand, 'Min Plus'?:
A soil enhancer and 100% remineralizer consisting of natural organic minerals, Minplus offers the benefits of rapid growth with reduced use of artificial chemicals.
Volcanic Rock In the form of a fine powder, volcanic rock dust contributes to soil friability and contains micro-nutrients not found in commercial NPK fertilisers.
It also serves as a natural insect deterrent.
Silicates are necessary in building plant protein and in the synthesis of certain vitamins in plants. Silicates function as a vital element in protecting plants against insects and fungi attack, strengthening qualities and have been found to influence other minerals useful in plant metabolism.
Plants need calcium for normal cell division, as a component of cell walls, as a component of the salts inside the cells and as a part of the genetic coding materials.
Magnesium is a key component of the chlorophylls, the green coloured cells in the plant.
It is therefore vital as chlorophylls are the cells which perform photosynthesis.
Also, plants need magnesium before thay can make use of phosphorous and magnesium also activates several different enzyme systems.
Iron is a constitutent of many compounds in plants that regulates and promotes growth.
It is especially important to the function of chloroplasts, the plant cells that contain chlorophyll, which are the particles that perform photosynthesis.
Potassium strengthens plant stalks and helps undo the stress induced by excess nitrogen.
Phosphorus is the "Go" food for plants.
Trace Minerals Minplus contains over 70 macro and micronutrients (such as copper, zinc, molybdenum, etc.) to replace depleted minerals and elements not supplied by commercial NPK fertilisers.
Think of these as salt and pepper - you don't need a lot of it, but without them, plant growth would suffer.
