Dynamic Accumulators – Nettle Nutrient Analysis

The Cannabis Horticultural Association (CHA) has embarked on a mission to re-analyze the potential of dynamic accumulators. Dynamic accumulators is a term used in the permaculture and organic farming literature to indicate plants that gather certain minerals or nutrients from the soil and store them in a more bioavailable form and in high concentration in their tissues, then used as fertilizer or just to improve the mulch layer. The first to use the term dynamic accumulator in the above definition was probably Robert Kourik in his book Designing and Maintaining Your Edible Landscape—Naturally (1986).
