Description

Analysis:

A full nutrient analysis of grape petioles consists of Nitrate, Total Nitrogen, Phosphorous, Potassium, Calcium, Magnesium, Sodium, Chloride, Iron, Zinc, Manganese, Copper, Boron, Aluminium and Sulphur.

Sample Collection:

It is recommended that sampling take place when the vines are 50-95% flowering.

Collect a petiole (leaf stalk) of a basal leaf opposite a flowering cluster.

One petiole from each of 100 vines throughout a planting is required. Collect from high, low, shaded, exposed – for a good representational sampling. Sample from vines in a zigzag pattern.

Miss the first 3 vines in each row if there is an access road adjacent. Avoid sampling vines growing within areas with unusual features such as rocky areas, poor drainage, sale affected, near fences, trees, water troughs or fertilizer depots.

Avoid soiled, diseased or damaged plants.

Do not sample petioles touching trellis wires or plants that are under water or temperature stress.

We advise sampling in the cool of the morning.

Plant tissue samples should be placed in labelled brown paper bags.

Maintain samples in a cool environment prior to and during transportation.

Do not seal samples in plastic bags or on unprotected ice – use newspaper or cardboard to keep separation.

Please request a free EasyTest Sample Kit for Grapevine Petioles which will include everything you need for taking your petiole samples:
5 Paper bags, 5 labels, 2 pairs of gloves, Reply-paid address labels and our Petiole Factsheet.
