Avaliação da polihalita como fertilizante influenciando a produtividade e sanidade no cultivo de repolho
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 polyahlite 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.
