Vitamins or minerals that are necessary to maintain health and that the body must obtain from outside sources.

Plant nutrients that are needed in very small quantities.

the essential plant nutrients needed in small quantities, also known as trace elements. Micronutrients such as iron, manganese and zinc often become unavailable in high-pH soil, and nutrient deficiencies result. See also: nutrient deficiency.

Plant nutrients that are needed in very small quantities.

Essential elements needed in very small amounts for healthy plant growth: iron, copper, zinc, boron, molybdenum, chlorine, and cobalt.

These are the elements needed by plants to maintain growth. Without them, the plant can't live. They are needed in small amounts and too much can cause toxicity. Examples are Iron, Copper, Zinc, Magnesium, Calcium, Sulfur, etc.

Also referred to a TRACE ELEMENTS, including S, Fe, Mn, B, Mb, An and Cu.

A group of trace elements that work with macronutrients to sustain plants. Although dozens of minerals may be of use to plants in nature, hydroponic nutrient blends use the most beneficial.
