Agricultural Gypsum - Calcium Sulfate
How much stone do I need?
How much stone do I need for the ground?
For pebble and gravel:
• approximately 80kg per m², based on a 5cm layer.*For particle sizes >32mm, a thicker layer is required.
• Consumption per sack: 1000kg = 0.625m³.
• Coverage: approximately 12.5m² with a 5 cm layer.
For pine bark:
• approximately 70L per m², based on a 5cm layer.
• Consumption per sack: 1000L = approximately 1m³ = approximately 600kg
• Coverage: approximately 14m² with a 5 cm layer.
For volcanic, slate and chamotte:
• approximately 50kg per m², based on a 5cm layer.
• Consumption per sack: 1000kg = approximately 1m³
• Coverage: approximately 20m² with a 5 cm layer
How much stone do I need to fill a gabion?
Density of approximately 1,650kg per 1m³.
The calculation is very easy to understand with an example: if you have a gabion of 100x50x30 cm, you must do the following calculations:
1x0.5x0.3 = 0.15m³
0.15x1,650 = 247.50kg of stone.
*It is always a good idea to calculate an extra 5%, since when gabions are filled they expand a little and a little more stone always fits than in the theoretical calculations.
Clarifications
ATTENTION!
The grain sizes of GRAVELS AND pebbles are sieve sizes
The actual sizes may vary slightly, since when talking about, for example, 60-80mm stone, it means that the stones pass through an 80x80mm square mesh and do not pass through a 60x60mm one.
Through that 80x80 mesh, a stone 100mm long and 65mm wide can pass, so there may be a percentage of stones larger than 80 and smaller than 60mm.
Breakage of pebbles
On the other hand, in pebbles larger than 60mm, there is a percentage of up to 10% of stones that can break during sorting, washing, loading and unloading; to this day we do not have machinery that prevents such breakages.
In the photos you can see, only real products are shown; broken pieces have not been removed.
Dust and sand in the products
This product is not washed, so it contains dust, sand and even traces of other products due to processing and transport. 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.

General Product Description
The Agricultural Gypsum, or Calcium Sulfate, is a technical mineral that improves soil structure and provides calcium and sulfur, key nutrients for plant development. Its action also corrects soil salinity, improving permeability and facilitating deep root growth.
Differences Between Granulometries and Recommended Uses
Granulometry 0-10 mm
Description: Larger particle size, with slow nutrient release.
Recommended uses: Ideal for soils requiring prolonged treatment. Perfect for long-cycle crops or clay soils needing gradual structural improvement.
Granulometry 0-3 mm
Description: Intermediate size providing moderate nutrient release.
Recommended uses: Versatile for various crops. Suitable for soils with moderate salinity correction needs or those seeking improvement both short and long term.
Granulometry 0-1 mm
Description: Fine size offering rapid nutrient release.
Recommended uses: Perfect for quick corrections in soils or short-cycle crops. Ideal for situations requiring immediate soil improvement, such as nurseries or intensive crops.
Granulometry 100 microns
Description: Ultrafine size offering ultrafast nutrient release.
Recommended uses: Perfect for rehabilitation of sodic soils, very quick corrections in soils or short-cycle crops. Ideal for situations requiring immediate soil improvement, such as nurseries or intensive crops.
Ideal Application Time
The Agricultural Gypsum can be applied year-round, but the optimal application times are usually:
- Autumn: Right after harvest, to prepare the soil for the next season. Autumn application helps improve soil structure during the colder months, ensuring it is in optimal condition for spring planting.
- Spring: Before planting or at the beginning of the growing season, when plants demand an adequate supply of calcium and sulfur. Applying in spring also ensures that nutrients are available during the active growth of plants.
- In arid areas or saline soils: Application can be particularly useful before rainy seasons, to maximize water penetration and facilitate sodium displacement in salinized soils.
Application Method
- Surface application: The Agricultural Gypsum should be spread evenly over the soil. Depending on the granulometry, it is advisable to use a fertilizer spreader to ensure homogeneous distribution.
- Incorporation into the soil: For better results, especially with larger granulometries (0-10 mm), it is recommended to incorporate the gypsum into the soil through light tillage or plowing. This ensures that nutrients penetrate deeper and mix better with the substrate.
- Subsequent irrigation: After application, especially in dry climates, it is ideal to apply moderate irrigation. Water facilitates the dissolution and distribution of calcium sulfate in the soil, accelerating its action.
- Application in direct seeding or pastures: In these cases, gypsum can be applied directly on the surface without tillage, and it will be rainwater or irrigation that carries the product to the deeper layers of the soil.
Benefits of Agricultural Gypsum (Calcium Sulfate)
- Improves soil structure: Promotes aeration and reduces compaction.
- Supply of essential nutrients: Provides calcium and sulfur, necessary for optimal plant growth.
- Correction of salinity: Helps displace sodium from saline soils, improving land quality.
- Improves water infiltration: Promotes greater water penetration into the soil, reducing runoff and erosion problems.
Advantages of Agricultural Calcium Sulfate
- 100% natural product
- Economical
- Easy application
