There are four main criteria which define the quality of potato:

  1. Tuber quality
  2. Skin finish
  3. Storage
  4. Cooking quality

A balanced crop nutrition program is important to help manage all of these criteria.

How to improve potato skin finish
How to improve potato skin finish
Skin finish is important as consumers increasingly demand potatoes with clean, attractive skins. Tubers with surface infections of skin diseases are less attractive and also likely to have a reduced storage life.
Lasting Freshness - Inner health, outer beauty
Cultivars differ in respect of their propensity to poor internal quality. This is related to a cultivar's tendency towards lush foliage growth, the development of only a few tubers per haulm, its susceptibility to soil-borne pathogens, leaf diseases and insect damage, its level of heat and drought tolerance, or the number of root hairs on the root tips. It is because of all these factors that certain cultivars tend to exhibit one or more characteristics of either poor or good internal quality.

Do you want to make better informed nutrient decisions ?

The farmer's toolbox is a collection of tools available to help you make better nutrient decisions by choosing the right fertilizer and apply the right amount of nutrients at the right time and in the right place so that the crop yield and quality are maximized whilst still keeping costs in check, avoiding over-fertilization and protecting the environment.
