SRC Calcium Carbonate
CaCO3 deficiencies caused by:
• Inadequate application rates.
• Dolomite, the most recommended and applied aglime is not reactive enough and can be inert.
• Not recognizing aluminum toxicity in soils and produce.
• Assuming soils that are high pH or deemed to be sufficiently calcareous will buffer progressive acidification.
SRC Calcium:
• CaCO3 in SRC has a loosely bonded nanocrystalline structure creating extremely reactive aglime the most effective in combating aluminum toxicity and soil acidification.
• All essential plant/ microbial/mineralogical nanoscale interactions in the soil have been enhanced in SRC trails. Organic chemistry, mineral/nutrient content (highest brix), accelerated germination, increased root mass and extent are all improved.
• These essential interactions extend to animals. Preliminary testing as a mineral supplement for laying hens SRC out performed all other calcium sources.
• CaCO3 in SRC is the most reactive and only magmatic, high calcium aglime available in bulk in North America. With credit for its other macro/micronutrients and high activity clay it is the lowest cost high calcium aglime available in the North American agricultural core.
SRC Biotite (Potassium Source)
“The transformation of biotite to vermiculite with the release of the interlayer K is perhaps the
most important biologically mediated geochemical reaction occurring in the rhizosphere”.
Banfield, Proc. Natl. Acad. Sci. USA 96, (1999)
• Biotite mica is primary, high energy clay, which exchanges potassium cations for OH and becomes vermiculite.
• Surplus potassium in the soil solution is reacquired by vermiculite reverting back to biotite. Thus potassium from biotite is 100% plant available compared to 20 to 25% for chemical potash fertilizers.
• Manure compost plus SRC biotite can supply all potassium requirements.
• Biotite functions as well as chemical fertilizer at supplying K within the growing season.
SRC Pyroxene (Magnesium Source)
• SRC pyroxene group of minerals rich in magnesium and iron and are the most reactive in Spanish River Carbonatite Complex deposit.
• Pyroxene is an excellent source of magnesium.
• During the formation of soil clays magnesium is consumed in large quantities to form high energy clay minerals such as chlorite, montmorillonite and illites.
• Pyroxene plays a very important role in this process.
SRC Apatite (Phosphorous Source)
• With unique & exceptional reactivity properties the apatite in SRC is the cleanest rock phosphate agromineral fertilizer with no radioactive or heavy metals.
• In a quality organic or conventional soil with high energy clays and nanoscale interactions intact, SRC phosphorous is 100% plant available as apposed to 10 to 15% plant available in chemical phosphate fertilizer.
• Hence at CaCO3 maintenance levels phosphorous sufficiency is achieved.
SRC Trace Elements
• SRC contains the most extensive suite of trace minerals of any organic or chemical fertilizer we have evaluated; many are critical catalysts in mineral/microbial/plant interactions and explain in part SRC’s response over a vast and complex array of soils and growing conditions.
