The question is..do YOU know anything about nutes
And i never said ash will tell you whats in it, though yes it can be analyzed just like your soil and used to alter ratios next season
So what is ash to you? What makes up the composition of ash in your mind
"the ash content is heavily dependent on plant type and growing conditions. Water uptake for example is directly related to uptake of Si and other inorganic elements in the plant. Thus, C3 plants which have on average higher water uptake compared to C4 plants also tend to have higher ash contents.
However, some C3 plants such as cardoon have been widely reported to have an ash content of 8% wt db or more. The use of fertilizers also affects the ash content in herbaceous biomass, particularly with regard to elements such as potassium, chlorine and phosphorus.
Soil conditions and –composition also plays an important role in virgin biomass. Some researchers have indicated that switchgrass growing on sandy soils resulted in lower overall ash and potassium content compared to switchgrass grown on clay soils. The level of soluble inorganic elements in a soil is important. As they have to be taken up by the plant
Finally, the ash content and composition of a plant tends to vary depending on the part of the plant. Leaves for examples typically contain higher amounts of ash than stems as thats where nutes are stored
Ash is the general term used to describe the inorganic matter in a fuel after burning. In biomass fuels, the ash content originates from the biomass itself, e.g. materials that the plant absorbed from the water or the soil during its growth, or from the supply chain, e.g. soil collected along with biomass. In any case, after the collection of a sample the ash content is typically measured by combusting the biomass at a laboratory furnace under controlled conditions, taking into account the relevant standard EN 14775.
most abundant in the ash: Al, Ca, Fe, Mg, P, K, Si, Na and Ti.
All the variances alter the burn properties and properties of the ash
Now why would you never compare weed and tobacco? I assume thats what you meant..
