Trace Elements Comments
TRACE ELEMENTS: Added Fish fertilizer or seaweed can furnish them and can be applied in addition to a regular fertilizer. OIE86JY-10 0
TRACE ELEMENTS: Added to a 20-20-20 Fertilizer They are not necessary as special additives; minor elements probably are present in the fertilizer itself, or in the water supply or in the tree-fern medium being used. A67-1010 0
TRACE ELEMENTS: Boron, Copper, Iron, Manganese and Zinc They need a slightly acid reaction in the compost for assimilation by the plants; copper and zinc are available in alkali; they readily chelate, which happens when an organic molecule envelops them; refer to OA78-51; this is not true and should be omitted. OWD 0
