“…The relative agronomic effectiveness (RAE) of the phosphate fertilizer associated with the biochars was higher (up to 100%) when compared to TSP in most cases ( Figure 3B). This effect was more pronounced in the second crop, which may be related to the effect of the biochars in providing better access to P by the plant (Blackwell et al, 2015). In a study with green peppers, researchers observed increases in productivity up to 20% with the use of fertilizers associated with biochar in relation to conventional fertilizers (Yao et al, 2015).…”

The use of fertilizers with some degree of protection of the phosphate ions can reduce soil adsorption and increase the absorption by plants, increasing the efficiency of phosphorus (P) fertilization. This study aimed to evaluate the performance of a phosphate fertilizer associated with biochar in granules in a P-fixing soil in a greenhouse experiment. Biochars were produced from two sources of biomass: sugarcane bagasse (SB) and wood sawdust (WS), which were pyrolysed at two temperatures (350 °C and 700 °C). After chemical and physical characterization, the biochar samples were granulated with triple superphosphate (TSP) in a 3:1 ratio (TSP: biochar). The agronomic evaluation of the fertilizers was carried out by two successive maize crops (Zea mays L.) in the greenhouse, using a factorial scheme of (5x3) in randomized block design with four replicates. The treatments consisted of five fertilizers (TSP-WS350, TSP-WS700, TSP-SB350, TSP-SB700, and TSP) and three P doses (100, 200, and 400 mg dm-3). It was evaluated the dry matter production, P uptake in maize and P available in the soil after cultivation. The results indicate that dry matter production, considering the P uptake by the plant and the P available in the soil when using a dose of 400 mg dm-3, presented higher results in both crop cycles and the recovery rate in both cultivations occurred inversely to the P doses. The simple association of biochar with soluble phosphate fertilizer did not increase the efficiency of P use by maize, but it increased available P in soil.

“…This results in loss of carbon and nutrients from the soil and a very large increase in harmful atmospheric carbon emissions 2 . Biochar production is seen as a key part of a strategy to effectively recycle biomass carbon and nutrients 3 , improve plant growth and mycorrhizal colonization 4 , improve soils physical and chemical properties, provide a source of renewable energy and act as a means for carbon sequestration 1,[5][6][7] . These vast quantities of readily available biomass, which are currently treated as waste for disposal, could be readily, cost effectively and widely converted into valuable biochar 1,[8][9][10] .…”

Dramatic changes in molecular structure, degradation pathway, and porosity of biochar are observed at pyrolysis temperatures ranging from 250 to 550 °C when bamboo biomass is pretreated by iron-sulfate-clay slurries (iron-clay biochar), as compared to untreated bamboo biochar. Electron microscopy analysis of the biochar reveals the infusion of mineral species into the pores of the biochar and the formation of mineral nanostructures. Quantitative 13C nuclear magnetic resonance (NMR) spectroscopy shows that the presence of the iron clay prevents degradation of the cellulosic fraction at pyrolysis temperatures of 250 °C, whereas at higher temperatures (350-550 °C), the clay promotes biomass degradation, resulting in an increase in both the concentrations of condensed aromatic, acidic, and phenolic carbon species. The porosity of the biochar, as measured by NMR cryoporosimetry, is altered by the iron-clay pretreatment. In the presence of the clay, at lower pyrolysis temperatures, the biochar develops a higher pore volume, while at higher temperature, the presence of clay causes a reduction in the biochar pore volume. The most dramatic reduction in pore volume is observed in the kaolinite-infiltrated biochar at 550 °C, which is attributed to the blocking of the mesopores (2-50 nm pore) by the nonporous metakaolinite formed from kaolinite.

“…Biochar is produced by thermal decomposition of organic material under limited supply of oxygen (O 2 ) and at relatively low temperatures (<700 ∘ C) [25]. The potential of biochar to improve plant growth is related to changes in the physicochemical properties of soils that lead to overall increases in microbial activity [26,27]. When conditioning soils, it is possible to enhance the effectiveness of beneficial or effective microorganisms by adding biochar, or a similar material with tiny perforations, in which the microbes can house themselves (Zimmerman, 2008) [18].…”

This paper reviews the role of Natural Farming as an ecological farming method to produce organically grown food of safe and high quality and at the same time improve soil quality and soil health. Currently, there is a dearth of information on the effects of Natural Farming approach on black pepper farms particularly in Sarawak, Malaysia. Previous studies on other crops had indicated positive outcome using the Natural Farming method. Thus, this paper discusses the essential role of effective microorganisms in Natural Farming and their potential in pepper cultivation. Through the action of effective microorganisms, this approach should be able to transform a degraded soil ecosystem into one that is fertile and has high nutrients availability. The mixed culture of effective microorganisms applied must be mutually compatible and coexist with one another to ensure its favorable establishment and interaction in the soil. Therefore, it is anticipated that introducing Natural Farming in black pepper cultivation can enhance the predominance of effective microorganisms in the soil, which in turn could lead to promising growth and yield of the crop.
