Overview

Field study assesses nutritional status and soil parameters of grapevine, suggesting organic options may lack efficacy against fertilizers.

Key Points

  • To evaluate the impact of various fertilizers and biostimulants on macronutrients in grapevine leaves and soil parameters.
  • Field study of two grapevine cultivars, 'Solaris' and 'Regent', using twelve treatments over six years.
  • Assessments of macroelement concentration in leaf blades during véraison and selected soil parameters.
  • Treatments included NPK, mycorrhizal substrate, organic fertilizers, and various biostimulants.
  • NPK fertilization increased leaf N and K but inadequate phosphorus nutrition despite soil phosphorus increase.
  • Organic fertilizers, biostimulants, and AMF were insufficient compared to mineral fertilizers for supplying nitrogen.
  • NPK treatment led to soil acidification and slightly increased total soil nitrogen and organic matter.
