Atrium Salis
Atrium Salis is a complexed calcium formulation, effective for controlling and preventing calcium deficiencies and for correcting saline waters and soils. It contains a high concentration of complexing agents with high exchange activity between calcium and sodium cations. Made from coniferous wood sulphite liquors, it is biodegradable.
- Saline water corrected: rate calculated from the SAR of the water to be reduced
- Saline soils: calcium-sodium exchange, through localised or surface irrigation
- Calcium deficiencies prevented and controlled, both as a foliar spray and through fertigation
- 14.4% complexed CaO and 6.5% nitric nitrogen
- Applied at the end of irrigation: without over-diluting the product
- Stable complexed fraction between pH 2.5 and 8.5
How to use
Form: liquid.
Application: in the last minutes of irrigation, without over-diluting the product; as a foliar spray to prevent calcium deficiencies. Do not mix with mineral oils, strong acids, copper, phosphates or sulphates; in case of doubt, run a test.
Crops: fruit trees, vine, horticultural crops and strawberry for calcium nutrition; any crop irrigated with saline water or grown on saline soils.
| Crop / Use | Application rate |
|---|---|
| Saline water correction (irrigation water) | 10–12 ml per SAR unit to be reduced; generally 25–75 ml/m³ of water |
| Saline soils – localised irrigation | 4–8 L/ha per week, up to 50–80 L/ha |
| Saline soils – surface irrigation | 7.5–15 L/ha per irrigation, up to 100–150 L/ha |
| Calcium deficiency – foliar (general) | 175–250 ml/hl every 10–15 days |
| Calcium deficiency – fertigation (fruit trees, vine) | 5–8 L/ha, from fruit set to harvest |
| Calcium deficiency – fertigation (horticultural crops, strawberry) | 2.5–4 L/ha, from the start of fruit set to the end of harvest |
