“…Organic matter is made up of humic substances comprising many negative charges and functional groups such as carboxyl, hydroxyl, and carbonyl, which react with Al and Fe to form stable complexes [61]. The affinity of ash for Al and Fe is associated with the presence of Mg and Ca oxides, which are capable of neutralizing soil acidity [62][63][64]. The effects of T6, T11, and T14 on soil-exchangeable acidity increased from 60 to 90 DAI.…”

In Ultisols and Oxisols, potassium (K) in the soil solution is leached from the rhizosphere before it interacts with soil colloids, or exchanged with other cations at the exchange sites of the soils because of the abundance of kaolinite clay minerals. These soils are highly weathered, low in organic matter, and low in pH, but high aluminium (Al) and iron (Fe) ions. Hence, K becomes unavailable for plants, and this compromises crop production and farmers’ profitability. The pH neutralizing effects of sago (Metroxylon sagu) bark ash and the ability of charcoal to chelate Al and Fe could be utilized to improve soil pH, reduce soil acidity, and improve K availability. The objective of this study was to determine the effects of amending muriate of potash (MOP) with charcoal and sago bark ash on selected soil chemical properties in a tropical acid soil (Typic Paleudults) over 90 days in a laboratory incubation. The proportions of charcoal and sago bark ash were varied at 20%, 40%, 60%, 80%, and 100%, but the MOP was fixed at 100% of the recommended rate. Selected soil chemical properties before and after incubation were determined using standard procedures. Results revealed that co-application of the soil amendments with MOP increased soil-exchangeable K compared with conventional practice. Moreover, amending the acid soil with charcoal and sago bark ash positively enhanced the availability of other base cations and soil cation exchange capacity (CEC). This was possible because the amendments increased soil pH and reduced exchangeable acidity, exchangeable Al3+, and exchangeable Fe2+. However, there was no significant improvement in water-soluble K (WSK) in the soil with or without charcoal and sago bark over the 90 days laboratory study. The findings of this study suggested that increasing soil pH could potentially improve soil K sorption capacity. Thus, the optimum rates of charcoal and sago bark ash to increase K availability were found to be 80% charcoal with 80% sago bark ash, 60% charcoal with 60% sago bark ash, and 80% charcoal with 40% sago bark ash, because these rates improved soil-exchangeable K+ and CEC significantly, besides minimizing soil-exchangeable acidity.

“…Wood ash (biomass ash) is a residue generated by the combustion of vegetal biomass, such as tree trunks, bark, and branches. Several studies have reported the positive effects of wood ash to correct soil acidity and its use as a fertilizer (Bonfim-Silva et al, 2020a;Reis et al, 2020;Bonfim-Silva et al, 2021).…”

Most soils are excessively acidic, which decreases the productive efficiency of plants. There are several ways to correct soil acidity to make nutrients available to crops. Wood ash is a residue generated by the combustion of vegetal biomass and is used to correct soil acidity for use as a fertilizer. The application of organomineral wood ash to crops is yet another alternative fertilizer that reduces the doses of wood ash and mineral fertilizer. The objective of this study was to evaluate the biomass production and water use efficiency of chrysanthemum cultivated with organic, mineral, and organomineral fertilizers associated with liming. The greenhouse experiment was conducted in a 5 × 2 factorial randomized block design with five fertilization managements (incubated wood ash, non-incubated wood ash, organomineral, mineral fertilization, and control) and two liming values (0 and 100% of the recommendation), with five replicates. Biomass production was significantly affected by fertilization alone and organomineral application resulted in higher biomass production. Incubated ash was more appropriate because resulted in higher yields.
