“…Post burning, appreciable quantities of P, Ca, Mn and Mg (about 75%) have been confirmed in the residue [26]. The application of wood ash for the growth of tropical plants is advantageous as it minimizes the Al and Mn toxicity, besides supplying the plants with nutrients [27]. The authors also emphasized already in that time for the care with due to the nutrient imbalance in the soil correction was necessary by the addition of supplements, mainly those of N, P and K.…”

Utilizing wood ash as a fertilizer in agriculture is a viable alternative to the soil nutrients absorbed by the crops. The aim of this study was to assess the phytometric and productive features of Brachiaria brizantha (cv. BRS Piatã) fertilized with wood ash in the Brazilian Cerrado. The experiment was performed in a greenhouse, adopting a completely randomized design, and applying five rates of wood ash (0, 5, 10, 15 and 20 g•dm −3 ) with five replicates. The shoot plant parts were subjected to three successive cuts 30-day intervals each. The results were submitted to the analysis of variance and regression analysis at 5% probability. The wood ash rates between 13 to 17 g•dm −3 clearly produced the best results for plant height (102.24, 84.42 and 63.27 cm), leaf/stem ratio (1.61, 1, 78 and 1.94), and chlorophyll index (46.66, 41.93 and 38.39), respectively, during the first, second and third evaluations. A 94% increase in the shoot dry mass (2 nd and 3 rd evaluations) and root parts was noted for the wood ash rate of 20 g•dm −3 , compared with the treatment involving wood ash fertilization. Wood ash affects the phytometric features, increases the chlorophyll concentration and thus the BRS Piatã grass production in the Oxisol of the Brazilian Cerrado.

“…Furthermore, the coupling of pollutants to the humic component of SOM may form more toxic compounds, such as dioxins and furans [58]. Therefore, successful management techniques have involved the introduction of recalcitrant SOM into the soil that can enhance the "locking up" of pollutants while providing suitable habitats and substrates for microbial degradation of bioavailable contaminants [59][60][61][62][63][64]. This can be achieved by the addition of biochar to soils [14,65,66].…”

Abstract:The presence of biochar in soils through natural processes (forest fires, bush burning) or through application to soil (agriculture, carbon storage, remediation, waste management) has received a significant amount of scientific and regulatory attention. Biochar alters soil properties, encourages microbial activity and enhances sorption of inorganic and organic compounds, but this strongly depends on the feedstock and production process of biochar. This review considers biochar sources, the production process and result of pyrolysis, interactions of biochar with soil, and associated biota. Furthermore, the paper focuses on the interactions between biochar and common anthropogenic organic contaminants, such as polycyclic aromatic hydrocarbons (PAHs), pesticides, and dioxins, which are often deposited in the soil environment. It then considers the feasibility of applying biochar in remediation technologies in addition to other perspective areas yet to be explored.

“…A cinza vegetal é um resíduo proveniente da queima da madeira que, dependendo de sua origem, pode ser utilizado como adubo (Nkana et al, 1998;Osaki e Darolt, 1991;Severino et al 2006). Cutter e Murphy (1978), explicam que, os principais componentes minerais da madeira são Ca, K e Mg; sendo Ca o elemento em maior quantidade, chegando a representar 50%, seguido respectivamente, pelo K, Mg, Mn, Na, P, entre outros.…”

Resumo: A cinza de madeira, embora pouco utilizada na composição de substrato para produção de mudas, pode conter nutrientes prontamente disponíveis e, por conseguinte, aumentar as condições de fertilidade do substrato. Por isso, foi realizado experimento com o objetivo de verificar a combinação de: solo, substrato comercial (Plantmax®) e cinzas de madeira, mais adequada para a produção de mudas de Eucalyptus camaldulensis. As mudas foram produzidas em tubetes com capacidade para 160 cm³, com uso de sementes germinadas em areia e vermiculita. Ao atingirem 15 cm de altura, as plantas foram transplantadas para os tratamentos: 100% solo; 75% solo + 25% cinzas; 75% Plantmax® + 25% cinzas; 50% solo + 50% cinzas; 50% Plantmax® + 50% cinzas; 50% solo + 25% Plantmax® + 25% cinzas, dispostos em delineamento inteiramente casualizado, com 10 repetições. A avaliação do crescimento ocorreu 90 dias após o transplante, com a medição da altura da parte aérea, diâmetro de colo, biomassa de folhas, biomassa de caule, biomassa de raízes e concentrações de nutrientes nas folhas. As combinações de substratos que proporcionaram o maior crescimento das mudas de E. camaldulensis foram 50% solo + 50% cinzas e 50% Plantmax® + 50% cinzas.

Wood ash on eucalyptus seedling productionAbstract: The wood ash, although little used in the composition of substrates for seedlings production, can contain readily available nutrients and, therefore, increase the fertility conditions of the substrate. Because of it was carried out experiment in nursery in order to verify the combination of: soil, commercial substrate (Plantmax®) and plant ashes, more suitable for the production of Eucalyptus camaldulensis seedlings. The seedlings were grown in plastic tubetes with a capacity of 160 cm³ using seeds germinated in sand and vermiculite. When they reaching 15 cm of height, the plants were transplanted to the treatments: 100% soil; 75% soil + 25% ash; 75% Plantmax® + 25% ash; 50% soil + 50% ash; 50% Plantmax® + 50% ash; 50% soil + 25% Plantmax® + 25% ashes, arranged in a randomized design with 10 repetitions. The evaluation of the growth occurred 90 days after transplantation, with the measurement of shoot height, diameter collect, the leaf biomass, stem biomass, roots biomass and concentrations of nutrients in the leaves of seedlings. The combinations of substrates that provided the greatest growth of E. camaldulensis seedlings were 50% solo + 50% ash and 50% Plantmax® + 50% ash.
