Description

Powerful mineral fertilizer

Rich in trace elements, silicon, calcium and magnesium. Boost the soil of your crops.

The basis of agricultural production is the soil, in recent years we have focused on "feeding" the crops and we have forgotten about the needs of the soil. Volcanic rock flour improves soil fertility and stimulates the biological activity of the soil, the result is fertile soil that gives good crops regardless of the crop.

 

3Ms Organic Agriculture

Organic Matter - Microorganisms - Minerals

It is a simple model that has worked for millions of years, now due to the overexploitation of soils, we must try to compensate for the wear and tear of the soil and the decompensation of the 3M, and this is where rock flours do their job, remineralizing the soil to achieve a perfect equation that allows stronger and more productive crops.

 

Advantages of volcanic rock flour or pozzolana

- Universal mineral fertilizer, provides Silicon, Calcium, Magnesium and iron among 70 other minerals.

- Revitalizes soils worn out either by the abuse of chemical fertilizers or by continuous monoculture, causing the clay-humus complex.

- Soil regenerator, loosens the soil, improving its structure for greater crop growth, especially in clay and compact soils.

- Increases the PH of the soil, reduces the content of exchangeable acid cations, increases the cation exchange capacity of the soil and increases the content of basic cations in the soil.

- Protects against pests and diseases.

- Retains and preserves moisture

- Its acids dissolve the minerals that the soil already has and the crops take advantage of them.

- Avoid nitrogen losses

Particle size distribution of rock flour

We have several granulometries, 0-1 mm. and micronized volcanic stone flour.

Micronized rock flour is more expensive but it compensates since the amount of input is reduced by having a higher contact surface than the 0-1 mm granulometry.

 

Amount of volcanic rock flour to contribute

In the case of application by sprinkling with micronized rock, 200 grams per 1 m² is sufficient, (2 tons per hectare) in the case of 0-1 mm rock flour. About 400 grams per m² (4 tons per hectare) will be needed. If applied directly to the plant we can reduce the amount needed by half.

Application using irrigation water, only use micronized rock flour, mix and apply with a continuous agitation machine.

How much stone do I need?

How much stone do I need for the floor?

For boulders and gravel:
• ±80kg per m², based on a 5cm layer. *For grain sizes >32mm a thicker layer is necessary. • Consumption per bag: 1000kg = 0.625m³.
• Covering capacity: ±12.5m² with a layer of 5 cm.

For pine bark:
• ±70L per m², based on a 5cm layer.
• Consumption per bag: 1000L = ±1m³ = ±600kg
• Covering capacity: ±14m² with a layer of 5 cm.

For volcanic, slate and chamotte:
• ±50kg per m², based on a 5cm layer.
• Consumption per bag: 1000kg = ±1m³
• Covering capacity: ±20m² with a layer of 5 cm

How much stone do I need to fill a gabion?

Density of ±1,650kg per 1m³.

The calculation is very easy to understand with an example, if you have a 100x50x30 cm gabion. you have to do the following accounts:
1x0.5x0.3= 0.15m³
0.15x1.650= 247.50kg. of stone.
*It is always good to calculate an extra 5%, since when the gabions are filled they widen a little and there is always a little more stone included than in the theoretical calculations.

Clarifications

ATTENTION!

Granulometries are sieve sizes

The actual sizes may vary slightly, since when we talk about a 60-80mm stone, for example, it means that the stones pass through a 80x80mm square mesh. and they do not pass through a 60x60mm one.
A 100mm stone can pass through that 80x80 mesh. long and 65mm. wide so there may be a percentage of stones greater than 80 and less than 60mm.

stone breaking

On the other hand, in stones larger than 60mm. There is a percentage of up to 10% of stones that can break during classification, washing, loading and unloading. Today we do not have machinery that prevents these breakages.

In the photos you can see, you only see real products, no broken parts have been removed.

Dust and sand in products

This product is not washed, so it contains dust, sand and even traces of other products due to processing and transportation. This is not a problem when using it; The stone will wash itself over time or you can pour water on it before using it.
