Kristallkalk keeps leaves cooler on hot days. The white film of fine lime crystals reflects part of the sunlight: in sugar beet, Bodenversum measured an average leaf temperature of 29.1 instead of 32.2 °C.

This does not slow down photosynthesis. On a hot summer day the leaf has more light than it can use; what holds it back is the heat. In every trial Bodenversum has shown us, the yield with Kristallkalk was above the untreated control.

Suitable for sugar beet, potatoes, cereals, vegetables, vines and fruit, and as a trunk coating. The needle-shaped crystals stick to the leaf better than ground limestone. Every application also brings calcium onto the leaf: 39 % Ca as calcium carbonate.

Apply with a crop sprayer: 6⁠–⁠10 kg/ha depending on water volume, 2⁠–⁠8 applications per season, no waiting period before harvest.

Nitrogen and potassium from sugar beet vinasse — 4 % N, of which 3.6 % is organically bound and of plant origin, plus 6 % water-soluble K₂O.

Listed on the FiBL input list for organic farming in Switzerland.

The nitrogen comes as protein and amino acids, not as a salt. Soil microbes mineralise it, so it is released more slowly than from a mineral fertiliser. The C/N ratio of 6.5 is narrow enough to avoid nitrogen lock-up — and the 26 % organic carbon feeds the soil life at the same time.

Via irrigation at max. 5 %, via the leaf at 0.4–1.5 %. Foliar application can leave spray marks — so do not apply to russeting-prone pome fruit varieties or during flowering.
