Unit 3 : Agricultural wastes and eutrophication

3.13.3.Minor Nutrient Availability and Consequences
All these elements are absolutely necessary to plant life, and readily supplied from tap, soil, and fish-food sources. Excepting specially filtered tap sources, non-soil amended set ups, systems without fishes and feeding, the minor or micro nutrients of aquarium plants are rarely found in limited supply, unless these are driven to being deficient by expediting growth and making the macro-nutrients alone available through supplementation.
Boron deficiency results in the stilted growth appearances of calcium deficiency.
