Post-harvest care of grapevines: Irrigation and nutrition

  • Date: 2014-05-05
  • Author: Smith, Jason and Holzapfel, Bruno

Temperatures in most Australian grape-growing regions are warm enough for vines to retain their leaves for a period of time after harvest. In cooler areas, this may only be for a few weeks, but more commonly it extends from 1 to 4 months in the hotter inland regions.

Cover crops and vine nutrition

  • Date: 2012-03-01
  • Author: Penfold, Chris and Collins, Cassandra

When it comes to nutrient requirements, grapevines are very economical compared to annual crops.

Molybdenum

  • Date: 2006-01-01
  • Author: Cooperative Research Centre for Viticulture

Molybdenum (Mo), is a micronutrient involved in the conversion of nitratenitrogen, taken up by the roots, into a form that the vine can use. It is also involved in enzymatic reactions essential for growth and reproduction in plants. Recent research indicated that molybdenum plays an important role in: grapevine fruit set; seed formation; berry formation and development; and bunch yield.

Nitrogen fertilisation

  • Date: 2006-01-01
  • Author: Cooperative Research Centre for Viticulture

Nitrogen (N) plays a major role in the growth and development of all parts of the grapevine. A significant amount of nitrogen is essential for normal vine growth.

Phosphorus fertilisation

  • Date: 2006-01-01
  • Author: Cooperative Research Centre for Viticulture

Phosphorus (P) is available via the slow breakdown of organic materials in the soil, or as an applied fertiliser. Most soils used for viticulture in Australia have low native concentrations of phosphorus and therefore phosphorus fertiliser inputs are normally required.

Potassium fertilisation

  • Date: 2006-01-01
  • Author: Cooperative Research Centre for Viticulture

An essential component of the vacuole of every plant cell, potassium (K) is also involved in protein synthesis, carbohydrate production, solute transport and maintenance of plant water status.

Trace elements

  • Date: 2006-01-01
  • Author: Cooperative Research Centre for Viticulture

Trace elements (also called micronutrients) are nutrients that are in very low concentrations in the grapevine but they play essential roles in vegetative and fruit development. The trace elements include copper (Cu), zinc (Zn), manganese (Mn), iron (Fe), boron (B), and molybdenum (Mo) (see separate VitiNotes for B and Mo).

Petiole analysis

  • Date: 2006-01-01
  • Author: Cooperative Research Centre for Viticulture

Petiole analysis is a useful tool to assess the nutrient content of vines at a selected time in the growth of the plant. It can be used to determine appropriate fertiliser applications in the general maintenance of a vineyard (nutrient monitoring) or to assist in determining the cause of specific problems (diagnostic testing).
