Besides unpredictable time and duration of flooding occurrence, low soil fertility has been another main agricultural issue at riparian wetland in Indonesia. The objective of this research was to determine the potential use of biochar in improving soil chemical properties, rice growth, and yields. Assessment on the effects of particle sizes (S) and application rates (R) of rice-husk biochar was executed through pot experiments in a greenhouse of Universitas Sriwijaya, Indonesia, from January to April 2017. The experiment was laid out in randomized block arrangement with three replications. S consisted of particle sizes ≤1 mm (S 1) and > 1 mm (S 2). R consisted of application rates at 1 t ha-1 (R 1), 2 t ha-1 (R 2), 3 t ha-1 (R 3), and 4 t ha-1 (R 4). Rice growth, yield, and growth analysis were measured during vegetative and generative stage. Soil chemical properties were analyzed after harvesting. Results indicated that application of biochar increased soil pH but did not affect cation exchange capacity (CEC), and availability of major soil nutrients. During vegetative stage, biochar application increased relative growth rate (RGR) and net assimilation rate (NAR) but decreased leaf are ratio (LAR). R 3 treatment significantly increased grain weight per panicle, number of filled spikelet, and weight of 1000 grains. Root and stem N content tended to be higher with biochar application. Application of biochar on riparian wetland soil exhibited some promising positive impacts on soil properties, growth, and yield of rice. However, a long term study on residual effects of biochar application in tropical riparian wetland needs to be pursued further for a more comprehensive understanding on this issue.

“…For instance, eucalyptus green waste biochar produced at 650-750 °C had 7000 mg kg −1 Fe (Abujabhah et al 2016); whereas, willow wood waste biochar produced at 550 °C had only 0.05 mg kg −1 Fe (Agegnehu et al 2016a). Several other studies (Brantley et al 2016;Chen et al 2018;Li and Shangguan 2018;Miranda et al 2017;Noyce et al 2017) also reported that biochar contains a low but significant amount of micronutrients.…”

Biochar, an environmentally friendly soil conditioner, is produced using several thermochemical processes. It has unique characteristics like high surface area, porosity, and surface charges. This paper reviews the fertilizer value of biochar, and its effects on soil properties, and nutrient use efficiency of crops. Biochar serves as an important source of plant nutrients, especially nitrogen in biochar produced from manures and wastes at low temperature (≤ 400 °C). The phosphorus, potassium, and other nutrient contents are higher in manure/waste biochars than those in crop residues and woody biochars. The nutrient contents and pH of biochar are positively correlated with pyrolysis temperature, except for nitrogen content. Biochar improves the nutrient retention capacity of soil, which depends on porosity and surface charge of biochar. Biochar increases nitrogen retention in soil by reducing leaching and gaseous loss, and also increases phosphorus availability by decreasing the leaching process in soil. However, for potassium and other nutrients, biochar shows inconsistent (positive and negative) impacts on soil. After addition of biochar, porosity, aggregate stability, and amount of water held in soil increase and bulk density decreases. Mostly, biochar increases soil pH and, thus, influences nutrient availability for plants. Biochar also alters soil biological properties by increasing microbial populations, enzyme activity, soil respiration, and microbial biomass. Finally, nutrient use efficiency and nutrient uptake improve with the application of biochar to soil. Thus, biochar can be a potential nutrient reservoir for plants and a good amendment to improve soil properties.

O biochar de lodo de esgoto (BLE) e o pó de rocha (PR) foram estudados em aplicações individualmente em diferentes regiões e cultivares, entretanto, o efeito da interação ou sinergia entre eles sobre o desempenho das culturas agrícolas, como do girassol ornamental, ainda não foi estudado. O objetivo deste trabalho foi avaliar o efeito da combinação de diferentes doses de BLE e de PR de origem micaxisto sobre aspectos morfológicos da cultivar de girassol ornamental sunflower sunbright. O cultivo foi realizado em vasos de plástico contendo 9,0 L da mistura de BLE, PR e Latossolo Vermelho Amarelo (LVA), no período 29 de junho a 10 de setembro de 2022. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 5 x 5, com as doses de BLE de 0, 2, 4, 6 e 8% base volume e doses de PR de 0, 1, 2, 3 e 5 t ha-1, com 6 repetições (vasos). Aos 10, 20, 40 e 60 dias após a semeadura (DAS) foram avaliadas a altura da planta (AP), diâmetro de coleto (DC), número de folhas (NF) e aos 60 DAS foi quantificada a fitomassa fresca da parte aérea (FFA), fitomassa seca da parte aérea (FSA), fitomassa fresca radicular (FFR) e fitomassa seca radicular (FSR). O uso de BLE nas doses 4, 6 e 8% apresentaram melhores resultados quanto a AP, DC, FFA, FSA, FFR e FSR e, as doses 5 e 7 t ha-1 de PR apresentaram aumento nos valores da AP, DC e FSA. A disponibilização dos nutrientes ao solo após aplicação de PR durante dois ciclos de cultivo do girassol ornamental foi reduzida, indicando que este deve ser utilizado com complementação de outra fonte nutricional às plantas.
