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).Continue reading Dynamic Accumulators – Nettle Nutrient Analysis
Examining the Management of Ecological Habitats for Beneficial Insects
With a growing concern for eliminating pesticide residue in cannabis, farmers are learning to incorporate beneficial insects into their Integrated Pest Management (IPM) methodologies. Along with this IPM comes the potential to integrate the habitats for these insects, which ultimately decreases a dependency of purchasing them. Regenerative and biodynamic management are now amalgamating with IPM, helping us develop new insight for the complexity of running these systems. This article will attempt to encompass the broad concepts of companion planting beneficial insects and discuss the caveats of landscape management for these integrated ecosystems.Continue reading Companion Planting for Cannabis
Dynamic accumulators (DA) are plants that gather certain minerals and nutrients from the soil and store them in higher concentration in their leaf tissues. The leaves of the plants can then be used as compost, mulch or liquid fertilizer. The truth is that most plants, in a way, are dynamic accumulators in some way because they translocate the soil minerals into their leaves. The difference however, is that certain plants, like horsetail, nettle or buckwheat, for example, tend to pull specific nutrients up in greater amounts. Horsetail is well known for silica, nettle is well known for iron and buckwheat is known for accumulating phosphorus. Other DA”s like comfrey or yarrow are more all purpose accumulators and pull out more proportional balanced NPK ratios. DA’s are traditionally thought of as a class of plants associated with nutritive and medicinal herbs. But please don’t confuse DA’s as a specific class of plants, for they can also include other types of flowers and cover crops as well.Continue reading Dynamic Accumulators Overview
By John Kitsteiner
Within the world of Permaculture we often find reference to plants known as Dynamic Accumulators. In brief, this is the idea that certain plants (often deep-rooted ones) will draw up nutrients from the lower layers of the soil, and these nutrients will be stored in the plants’ leaves. When the leaves fall in autumn and winter and are broken down, those stored nutrients are then incorporated into the upper layers of the soil where other plants will benefit from their deposition….
