Definitions

  • the invention relates generally to fertilizer compositions and, more particularly, to fertilizer compositions comprising wood ashes and preferably tree bark ashes. Even more particularly, the present invention relates to an improved method of producing high quality, natural and organic fertilizers comprising mycorrhiza and tree bark ashes. In some embodiments, various other substances are used as raw material such as bone powder, fish and crustaceans residues and algae.
  • the fertilizer formulations disclosed herein are ideal for acidic soils as well as soils with low nitrogen.
  • the major elements used to synthesize the organic compounds needed to grow trees are carbon (C), oxygen (O) and hydrogen (H).
  • C carbon
  • O oxygen
  • H hydrogen
  • the purpose of incineration of biomass is to release the chemical energy stored in the chemical bonds of the organic molecules as heat energy. This is achieved by oxidation of the organic compounds. During the oxidation the greater part of the organic compounds are volatilised as C02 and H20, the same constituents that the tree once used as building blocks during photosynthesis.
  • N and S are also volatilised as nitrogen oxides (NOx) and sulphur dioxide (S02).
  • sewage sludge In an attempt to synthesize a complete fertilizer from wood ash, one study (Pesonen et ah, 2015) co-granulated wood ash, or bio-ash, with sewage sludge and lime and concluded that the concentrations of nutrients (Ca, K and P) were reasonably high.
  • the sewage sludge provided the nitrogen whereas the addition of lime improved the neutralizing capacity of the granules.
  • the fertilizer was complete and of good quality, a pitfall of this particular formulation is the access to sewage sludge which is not necessarily easily accessible in large quantities on farms.
  • the fertilizer composition according to the present invention comprises wood ash that is not granulated using traditional granulation equipment but that is rather agglomerated to form less dense clusters that can be combined with organic matter using the method disclosed to create a complete and more optimal bioavailable fertilizer for use in agriculture.
  • granules or clusters of manure such as poultry manure can be added to the wood ash as a source rich in nitrogen.
  • Other substances which may be used in the present invention are dried and powdered fish and crustaceous residues, bone powder, mycorrhizae, and binders such as algae, fish residues or Lignosol® pelleting aid. Additional sources of manure can also be used and in a separate embodiment of the present invention such as equine manure.
  • Figure 1 is a flowchart which illustrates a prior art method for granulating all components of the fertilizer at once which limits bioavailability;
  • FIG. 2 is a flowchart which illustrates an embodiment of the invention.
  • Figure 3 shows the different liming power of the lime (dotted line) compared to free (i.e. ungranulated) wood ash (solid line).
  • Table 1 Typical element concentrations in wood ash (mg/kg)
  • Table 2 Typical metal concentrations in wood ash (mg/kg)
  • composition of fertilisers made in accordance with the teachings of the present invention are provided hereunder:
  • the percentage (by weight) of wood ash can vary between 30% and 55% depending on the need to increase the pH of the soil. The more wood ash, the greater the liming effect.
  • the percentage (by weight) of manure can vary between 30% and 60% depending on the need to add Nitrogen to the soil.
  • the percentage (by weight) of fish/crustacean/bone powder can vary between 10% and 15%.
  • Mycorrhizae may be added (between 0% and 5%) to increase the formation Mycorrhizal networks which are underground hyphal networks created by mycorrhizal fungi that connect individual plants together and transfer water, carbon, nitrogen, and other nutrients and minerals.
  • the organic components be granulated or agglomerated together and that the inorganic components be separately agglomerated to form clusters but not granulated.
  • a binder such as algae, fish residues or Lignosol® pelleting aid may be used as needed to form granules or clusters with the organic materials.
  • the humidity content of the fertilizer should be adjusted to be in the range of between 7% and 15%.
  • Step 1 Mixing wood ashes together as needed to form clusters.
  • Step 2 Adding bone powder to the clusters formed in Step 1.
  • Step 3 Mixing the manure, the mycorrhizae and the binder to form granules or clusters.
  • Step 4 Mixing the wood ash clusters with the organic granules or clusters.
  • Step 5 Putting the mixed granules and clusters of Step 4 in bags or other containers.
  • the bone powder is used to create a coating on the wood ash granules so as to slow down but not prevent the release of the nutrients from the wood ash into the soil. This can be done by missing the wood ash and the bone powder together at the same time or by mixing the wood ash so as to form clusters and then adding the bone powder which will form a coating on the wood ash clusters.
  • the fertilizer composition of the invention is spread on the soil in late fall.

Abstract

De manière générale, l'invention concerne des compositions d'engrais et, plus particulièrement, des compositions d'engrais granulés comprenant des cendres d'écorce d'arbre. Plus particulièrement, la présente invention concerne un procédé amélioré de production d'engrais naturels et organiques de haute qualité comprenant de la mycorhize et des cendres d'écorce d'arbre sans nécessiter aucun liant. Dans certains modes de réalisation, diverses matières organiques sont utilisées comme matière première telle que des résidus de cendres d'arêtes de poisson et d'algues. Les formulations d'engrais divulguées dans la description sont idéales pour des sols acides ainsi que des sols à faible teneur en azote.
