Fertiliser application

Pre-planting

  • To correct soil deficiencies or high acidity (raise pH above 6)
  • To give young plants a good start in life

Especially used for slow-migrating minerals like P, K, Ca & Mg, not usual for nitrogen, due to high level of mineralisation of organic matter & high mobility. The application should be based on soil analysis. It is common to add organic manure to improve soil structure and stimulate soil life at the same time.

Fertilising established vines

Based on previous assessments, it is important to achieve a balanced nutrition, in particular: Mg / K, N / K, Mn / Fe. In terms of timing:

  • N in the spring. This is the greatest period when the vine’s demand outstrips the soil’s supply is at flowering
  • P & K in autumn (or spring in light soils)
