Dr. Fabio Vale, IPI Coordinator for Latin America, presented this poster at CBCS (XXXVI Congresso Brasileiro de Ciência do Solo) in July 2017.

The poster "Evaluation of polyhalite as a fertilizer influencing yield and health in cabbage crop" summarises a recent experiment. The experiment explored how cabbages respond to polyhalite fertilizer, a natural, multi-nutrient mineral containing four key plant nutrients: sulphur, potassium, magnesium, and calcium.

The main conclusions were that:

  • Polyhalite increased vigor and reduced leaf rot potential
  • Partial replacement of MOP by Polyhalite increased crop productivity; the ratios between 40 and 80% Polyhalite in the blend with MOP are the most indicated, even in high fertility soils.
