YaraVita Caltrac BZ

YaraVita™ Caltrac™ BZ liquid calcium fertilizer with boron and zinc 10 L container

YaraVita™ Caltrac™ BZ is a highly concentrated flowable calcium fertilizer, with added boron and zinc, for foliar application. It contains 2.5 times the calcium of chloride- or nitrate-based liquids, and its excellent crop safety allows higher calcium inputs. That makes it ideal for building fruit quality in citrus, apples, pears, stone fruit, avocados and vegetables. High-purity raw materials and a crop-safe formulation protect crop quality and help ensure produce is accepted throughout the supply chain.


  • High calcium concentration: calcium with boron and zinc in one product. Analysis: 400 g/l Ca, 31 g/l Zn, 3 g/l B.
  • Wide tank mixability: can be co-applied with most agrochemicals, saving time and money. Check your mix for free in TankmixIT.
  • Fast uptake, lasting effect: a controlled particle size gives quick absorption and long-lasting feeding, so fewer repeat sprays are needed.
  • Safe for crops and operators: formulated for maximum crop safety and easy to measure, pour and mix.
