Nutritional Requirements O F Substrates for Ornamental Plant Cultivation

It is well known that growth and yield of horticultural crops can be greatly increased by optimizing the nutritional status of the root environment. Based on plant response, involving numerous fertilizer experiments for the different plants and substrates involved, guidelines can be proposed for optimal nutrient solution and pot substrate conditions. The main factors to be considered are sampling technique, pH, electrical conductivity (EC) and the chemical plant substrate composition (nutrients as well as other constituents such as Na, CI, and the like).
