VOLCANIC ROCK DUST
Rock dust, also known as rock powder and rock flour, consists of finely crushed rock, processed by natural or mechanical means, containing minerals and trace elements widely used in organic farming practices. The rock dust should be a finely ground product as this allows it to be more readily broken down by the processes under the soil.
A few of the rock-dusts that are used in agriculture include RPR (reactive phosphate rock), limestone, serpentine, dolomite, basalt, granite, gypsum and greensand (glauconite- potassium and iron)
The volcanic rocks basalt and granite often contain very good levels of essential macro-compounds, trace elements, and micronutrients. Rock dust on its own is not a fertiliser, for it lacks the qualifying levels of nitrogen, potassium, and phosphorus.
The benefit of the addition of a quality volcanic rock dust to the soil is in the remineralisation that takes place. This is the return of minerals to the soil which had been lost by erosion, leaching, and or over-farming.
Totalfert’s TotalBLEND includes several types of rock dusts that provide good levels of various macro and micro elements.
Volcanic rock dust can be added to soil to improve fertility and has been tested since 1993 at the Sustainable Ecological Earth Regeneration Centre (SEER Centre) in Straloch, near Pitlochry, in Perth and Kinross, Scotland. Further testing has been undertaken by James Cook University, Townsville, North Queensland.
SEER’s research claims that the benefits of adding rock dust to soil include increased moisture holding properties in the soil, improved cation exchange capacity and better soil structure and drainage. Rock dust also provides calcium, iron, magnesium, silica, phosphorus and potassium, plus trace elements and micronutrients. By replacing these leached minerals it is claimed that soil health is increased and that this produces healthier plants.
Silicon is thought to be the major element affecting the strength of cell wall development. However it is the amount of available silica that has a dramatic effect on the plant strength and subsequent health. Silicon comes in silicon multi-oxide molecules (e.g. SiO2, SiO4, SiO6, SiO8 etc.). Each molecule shape is thought to pack in different ways to allow different levels of availability.
TotalBLEND provides over 16% silicon per tonne.
Often phosphorus can be locked in soils due to many years of the incorrect application of traditional fertilisers. The use of micronutrient rich fertiliser enables plants to access locked phosphorus.
A balanced ratio of calcium, magnesium and potassium assist in correcting the soil’s PH. This ratio is often referred to as the base saturation level. The microbiology is able to perform at their optimum once the correct ratios of macro and micro-elements are achieved.
