XTRA CALCIUM is a Liquid fertiliser to improve yield quality (size, structure and taste), for better storage and longer shelf life Higher fruit quality (size and colour) and better taste (sugar content):
- Efficiently prevents and corrects Ca deficiency related symptoms.
- Complexed with a natural coating agent: more efficiency and no risks.
- Reduces distribution losses and improves leaves absorption.
Characteristics XTRA CALCIUM is a fast-acting, liquid formula with high complexed calcium content, an essential component of plant nutrition, which contributes in a number of important metabolic functions: Highly soluble in water, homogeneously spread on leaves and quickly absorbed by the pores. Prevents and corrects symptoms related to calcium deficiency such as ‘bitter tip’ on apple, ‘tip burn’ on green vegetables, ‘blossom end rot’ on solanaceae and ‘internal browning’ of potato, etc. Activates calcic effects on plant enzymes and its functions on cell walls and membranes structure to improve yield quality. Better storage quality and longer shelf life.
XTRA CALCIUM is 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.
The high quality of raw material used in XTRA CALCIUM is ideal for foliar use as well as by fertigation, on all crops and at any growth stage. The rates indicated in the table below are only indicative.

XTRA CALCIUM 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.
