XTRA Ca-Mg is a fast-acting, highly soluble, homogeneously spread and quickly absorbed liquid formula with high content of complexed calcium and magnesium:
- Activates photosynthesis, with higher absorption of phosphorus.
- Improves yield quality, enhances organoleptic characteristics.
- Prevents and cures multiple Ca and Mg micro deficiencies.
- Complexed with a natural coating agent: more efficiency and no risks.
- Reduces distribution losses and improves leaves absorption.
XTRA Ca-Mg is a fast-acting, highly soluble, homogeneously spread and quickly absorbed liquid formula of a complexed mix of calcium and magnesium to prevent and correct micro deficiencies related to the inhibition or absence of these important minerals in plant nutrition especially under very low soil pH. Calcium activates the plant metabolic effectiveness to create the kind of healthy development needed in the growing season to increase yield and quality (including post-harvest quality), overcoming the limitations of the soil. Magnesium is an essential component of the chlorophyll, those essential for activation of enzymes necessary in photosynthesis (plant greenness). Magnesium also simulates the absorption of phosphorus and the synthesis of sugars, which improves organoleptic characteristics of yields. The micronutrients are complexed with a natural coating agent (ammonium lignosulphonate) to make the product more stable over a wider pH range and to give a superior performance with foliar application and a greater protection of minerals when applied in fertigation. This complexing technique, due to its natural source in symbiosis with the crop tissues, helps reduce solution viscosity and solution insolubility, and protects from leaf burns and other phytotoxicities. It also gives good distribution of the micronutrients over the leaf surface without the need for additional adjuvants.
XTRA Ca-Mg is ideal for foliar use as well as by fertigation, on all crops and at any growth stage. The rates are only indicative.

XTRA Ca-Mg is compatible with most soluble fertilisers and pesticides, except alkaline/copper products, phosphorus, sulphur and oil based products. Before using previously untried mixes, we strongly recommend performing a compatibility test on a small sample.
