Vineyard nutrition not an exact science as:

• Soil fertility is a complex concept
• Low nutrient crop, as:
  • Little is exported from the field
  • Perennial plants explore a large area of soil
• Influence of rootstock
• Problem of quality vs. quantity

Grapevines are able to grow and crop satisfactorily in a wide range of soils but many ignore vine nutrition at their peril! It is therefore important to answer these questions:

1. What are the essential elements for growth and performance of vines?
2. How can you measure the need for these?
3. What fertilisers can you use to fulfil this need?
4. How much and when should these be applied?
