The Complete in Soil Nutrient Management Solution

VolcaMin works as a fertiliser battery, charging when free nutrients are available, holding them from leaching and releasing them to plant demand as required.  Volcamin is not effected by temperature and reduces the leaching of nutrients under hot tropical conditions, holding them for use by the plant instead.

Volcamin is also an excellent capillary distributor of water due its highly porous properties, assisting infiltration, holding water higher in the pot and distributing water and nutrients more evenly through the mix which is important especially under drip irrigation. It is used in several leading wetting agents.

Use of Volcamin will soak up excess ammonium and other cations in mixes often released under hot conditions, preventing root burning.  Volcamin is marginally alkaline and a source of available calcium so its use with fertilisers can help buffer pH levels thus reducing the need for lime applications.

Volcamin carries a negative ionic charge which naturally attracts positive charged cations like ammonium, potassium, magnesium and calcium. The open crystalline structure of Volcamin has many storage sites for these ions which hold naturally through a loose chemical bond. These fertiliser ions are available to plants. Volcamin has a very high cation exchange capacity and thus increases the mixes ability to hold and release nutrients. As cations are water soluble they escape from mixes by leaching.   Volcamin is the perfect planting partner as it is a natural wetting agent and distributor of water as well as an electrically charged fertiliser magnet.

It helps water penetrate sandy non-wettable soils and will evenly distribute water around drippers and soak lines. It should be used in planting holes, mixed with the top 10-15cm of soils or a mulch.

As a planting amendment, it makes a permanent difference as it won’t break down or be eaten by microbes in the soil. Volcamin has ten times the nutrient holding capacity per litre than peat and helps prevent environmental leaching of nutrients into waterways.

VolcaMin Nutrient Efficiency System for Agriculture & Plantations

The Complete in Soil Nutrient Management Solution 

Incorporating VolcaMin into your soil conditioning and fertiliser program is a long term investment in the productivity of your soils and return on your fertiliser investment. Mixed into holes at planting, banded or applied around existing plantations or mixed with fertiliser blends, VolcaMin will improve plant available nutrient uptake and conversion to yield. Volcamin dramatically improves poor soils and as it doesn’t break down and is not consumed by microbes it is a permanent amendment and conditioner.

Enables better growth through permanently improved water & nutrient retention

Improved Nitrogen Uptake

VolcaMin particular affinity to attract and hold ammonium enables it to catch and hold nitrogen fertilisers from leaching through the soil for maximum plant available nutrition. Plants readily extract the stored nitrogen they require from the Volcamin by active root uptake.

Improved Nitrogen Recovery from plant tissue

Cornell University USA

• Recovery of applied Nitrogen from grass in Volcamin amended sand profile
• For the sand profiles, the percentage of applied fertilizer N that was recovered in grass clippings ranged from
• 62% to 70% of the applied N
• The addition of 10% Volcamin to the sand resulted in a greater amount of the fertilizer N ending up in the bent grass clippings
• 75% to 93% of the applied N.
• This difference was most noticeable at the lower N application rate.
• Adding 10% Volcamin to sand also resulted in substantially less nitrate leaching.
• Leaching of NO3 reduced by 88%
• Leaching of NH4 reduced by 99% VolcaMin with VolcaMin

Improved Potassium Uptake

Potassium is a vital nutrient for flower and bud initiation and is one the most expensive nutritional element. VolcaMin particular affinity for potassium enables it to be stored in the soil for efficient plant use. Potassium is often critical to yield.

Naturally extracts Phosphorus

VolcaMin can naturally assist in releasing phosphorus from soil lock ups or mineral apatite’s. Plants extract the stored ammonium and potassium from the Volcamin by active root uptake, exuding hydrogen ions to replace the nutrient on the Volcamin structure. This loosely bonded hydrogen then exchanges back into the soil as the Volcamin more strongly attracts calcium ions, even breaking the bond of phosphorus and calcium to pull the calcium onto the Volcamin, releasing the phosphorus to plants.

Improved Fertiliser Conversion

A trial effect of Volcamin on Clipper malting barley, was carried out by Australian Agricultural Technology at Barooga, NSW

• Incorporation of the VolcaMin increased the barley yield
• With DS by 16% and with DAP by 18%.
• The DAP plus VolcaMin yield was 34% greater than the DS alone yield.
• Volcamin with DAP increased the seeds per head, filler number, yield and protein content of the Barley.

Improves Soil Structure

Volcamin improves soil structure with its massive internal surface area and porosity. This surface area creates considerable surface tension with available water exerting a great capillary pull. This equates to a natural wetting agent effect with greater infiltration of water into soils and more even capillary distribution throughout the soil. This assists in holding more water higher in the soil profile and spreading available water more evenly from irrigation points. As the Volcamin is mildly alkaline, it has a liming effect on acid soils.

Echuca Tomato Trial

Property of Mick Cox

The trial was arranged through PIVOT representative Russell Nichol to evaluate the effect of addition of VolcaMin at the rate of 125 Kg/HA in addition to normal fertilizer program on processing tomatoes. The VolcaMin was added with Pivot 16 fertilizer at final stage of bed preparation prior to direct seeding.

Approximately 1 HA was treated (3 rows). No obvious growth response was noted and crop was mechanically harvested on 17th March 1992. Two control rows were harvested adjacent to treatment rows, the third being harvested further up the paddock where they had been operating before we harvested the trial.

Bundaberg Tomato Trial

TRIAL DESIGN:

The plants were grown in raised rows 9” wide with 27” spaces between rows. VolcaMin was applied within the rows at a rate of .5 tonne and 1 tonne equivalent per acre. The VolcaMin was incorporated with the fertiliser directly into the rows at the time of planting and watering was by trickle irrigation. The actual application rates for the trial where the rows only form ¼ of the total area, was 0.125 and 0.25 tonne per acre respectively.

YIELD ASSESSMENT:

A known length of row (75 feet) was picked by hand in the treated rows and in the adjoining untreated row and yields recorded.

Total Harvest Results The one tonne per acre (equivalent) VolcaMin row yielded overall a 10% increase in fruit size with an accompanying 10-12% increase in yield weights.

ECONOMIC BENEFITS:

Average yields on tomato production in Bundaberg are 1500-2000 cases per acre. The 10% increase in yield produced an additional 150 cases of tomatoes per acre valued at $1500.

Trial in a Commercial Trellis Tomato Crop, Tatura Victoria 2003

• The effect of Volcamin banded pre-planting at a rate of 1.4t/ha on a crop of indeterminate tomato (cv Red Ruby) grown on Shepparton Fine Sandy Loam was investigated at Murchison East in the Goulburn Valley between January and May 2003.
• A significant increase in medium and large fruit grade fruit was observed in the Volcamin treatment.
• The improved yield may be related to nutrient uptake that was significantly altered when compared with an untreated control
• High potassium levels in petiole sap
• Lead to more flower, bud initiation & fruit
• Potassium is a key driver of flowering and yield

Potassium is a vital nutrient for flower and bud initiation and is one the most expensive nutritional element. VolcaMin particular affinity for potassium enables it to be stored in the soil for efficient plant use. Potassium is often critical to yield.

Crop performance & yield

The Volcamin treatment had a significantly higher number (P=O.007) and yield (P=O.003) of medium-grade fruit, as well as a significant increase in Iarge fruit yield (P=O.042). Total fruit number was significantly (P=O.071) higher in the Volcamin treatment, although there was no significant total yield increase.
