Woody Mulch Mix is NOT made from the average woodchip. (woodchips can be used in creating rich soil, yet woodchips are not what goes into a woody mulch mix)
Woody Mulch Mix (see Types of WoodChip below)
The Woody Mulch Mix can be described as a mix of Ramial Wood Chip, plus approx 10% wood chips plus approx %20 SHREDDED (not chipped) branches of any size. Unlike the Ramial, the wood from heartwood and branches larger than 30cm in diameter is desirable due to its larger size, density which is conducive to the continued aeration of the soil, the near impossibility of compaction, both necessary for micro-organisms to be happy. the high C/N ratio (approximately 600:1), which even though this requires a lot of nitrogen in its decomposition, it can be well integrated into this Woody Mulch Mix – the benefits outway the C/N ratio. Just add some nitrogen rich compost or urine if you want to be sure of enough nitrogen.
You need a shredder. hire or buy. Look up chipper shredder reviews. OR you might be able to obtain Mulch which is near-enough to Woody Mulch Mix from your nearby Council Green Waste Management (see note below).
Ingredients: all kinds of green and brown garden waste, mostly green leaves and twigs and small branches, with a good amount of biggish chunks of wood.
Method: chip and shred it all. a bit of green leaves, a bit of dried leaves, a branch, so that it creates a pile of a MIX of all these ingredients – it is easier to mix as you go, rather than mix it once it is in a pile.
Note: there are some council waste facilities who use contractors who shred the local resident’s and tree-feller’s green waste into the correct consistency. the correct consistency is extremely important. it has to be place where micro-organisms will want to live. and then the council gives it away (or sells it back to the ratepayers). – ultimately, you cannot be sure if there are toxic substances in the council mulch or not. or perhaps your council is really on the ball and CAN guarantee the mulch to be toxic-free.
Types of Wood Chip
Wood Chip from branches and trunks larger than 30 cm. This is “chipped” – cut with a sharp blades into hardwood chunks
Woody Mulch Mix – the right method and mix is described above
Ramial Wood Chip (RWC) (from WikiPedia) Ramial Chipped Wood (RCW) is a wood product used in cultivation for mulching, fertilizing, and soil enrichment. The raw material consists of the twigs and branches of trees and woody shrubs, preferably deciduous, including small limbs up to 7 cm. (23⁄4 in.) in diameter. It is processed into small pieces by chipping, and the resulting product has a relatively high ratio of cambium to cellulose compared to other chipped wood products. Thus, it is higher in nutrients and is an effective promoter of the growth of soil fungi and of soil-building in general. The goal is to develop an airy and spongy soil that holds an ideal amount of water and resists evaporation and compaction, while containing a long-term source of fertility. It can effectively serve as a panacea for depleted and eroded soils.
The raw material is primarily a byproduct of the hardwood logging industry, where it was traditionally regarded as a waste material. Research into forest soils and ecosystems at Laval University (Quebec, Canada) led to the recognition of the value of this material and to research into its uses. Originally termed BRF (French: “bois raméal fragmenté” or “chipped branch-wood Because they are the most exposed part of the tree to the light, and the most actively growing, young branches (and young trees) used in RCW are from the richest parts of the trees. They contain 75% of the minerals, amino acids, proteins, phytohormones and biological catalysts (enzymes) found in the tree.
The wood from heartwood and branches larger than 3 inches in diameter is not desirable due to its high C/N ratio (approximately 600:1), which requires a lot of nitrogen in its decomposition.
