Morganics fertiliser 8kg


A well-balanced certified organic fertiliser that is a combination of chicken manure, processed fish, kelp, finely crushed rock dusts along with additional beneficial minerals and plant matter including eco-friendly certified phosphate, potassium, boron and sulphur.

N – 2, P – 2, K – 5, S – 2, Mg – 2, Ca – 8, Si – 12

One of the differentiating components of this fertiliser is the addition of rock dust. Rock dust consists of finely crushed rock, processed by natural or mechanical means, containing minerals and trace elements widely used in organic farming practices. It should be finely ground to allow 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 (which is primarily glauconite – a potassium, iron, aluminum silicate).  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, because 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.

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.
