Improve nutrient availability and soil structure.
TRUCAL® can be used to improve nutrient availability and soil structure by naturally neutralising soil acidity.
TRUCAL® is a granular limestone containing 99% calcium carbonate which has been carefully crushed and screened. The fine granules are effective and easy to spread.
TRUCAL® works to neutralise soil acidity by reducing the amount of acidifying free hydrogen ions. The high neutralising value of 55.6% and fine granulation of Trucal® improve its effectiveness and ease of use.
