“…In these production areas, soil nutrient levels are low and acid subsoils have high exchangeable Al levels. Thus, a successful cover crop must produce high yields of biomass with high C:N ratios and low decomposition rates under water and heat stress in acid, infertile soils with Al toxicity (Boer et al ., 2007; Pacheco and Petter, 2011; Torres et al , 2008). Pearl millet is one of the few plant species that meets these requirements (Boer et al ., 2007).…”

“…is the sixth most important world food crop (FAO, 2017) with 96% of the 27.8 million MT production in semi-arid tropical environments of Asia and Africa. In addition, it is a valuable forage crop in Australia and in the Americas, and recently has become widely used as a cover (mulch) crop in Brazil (Calegari et al ., 2014; Pacheco and Petter, 2011). FAO (2017) indicates no pearl millet production in Brazil; however, França and Miyagi (2012) estimated pearl millet production area had increased to 5 million ha during the last 30 years due to expanded use as a cover (mulch) crop.…”

Pearl Millet Production Practices in Brazil: A Review

2017

SUMMARYPearl millet [Pennisetum glaucum (L.) R. Br.] is grown as a forage, cover and grain crop in Brazil. Historically, forage production has the most important use, but during the last 30 years, the use as a cover crop in no-till soybean [Glycine max (L.) Merrill] production systems has expanded greatly and is currently used on over 5 million ha. Grain production as livestock feed is presently of minor importance but expanding. This review cites 125 references and documents pearl millet research conducted in Brazil which is largely published in Portuguese. The review addresses recommended pearl millet production practices for different uses, including stand establishment, row spacing and plant population, fertiliser and pest management, and the use of pearl millet in rotation and as a cover crop between soybean or maize (Zea mays L.) production to reduce crop losses from nematode infestation. It is concluded that greater research investment in crop improvement, fertiliser and pest management, nematode management, and forage/grain utilisation is needed to fully take advantage of pearl millet to meet feed, food and soil improvement needs in Brazil. In addition, creation of a database on pearl millet production, marketing and utilisation to assist farmers and grain merchandisers, and increased extension programming on pearl millet production is needed.

“…In addition, acrocomia could be a model crop for the provision of various environmental services and the ecological restoration of degraded pastures in extensive areas of Brazil, potentially contributing to biodiversity increment (as a native plant, acrocomia negative impacts on biodiversity can be lower in comparison to exotic species [8]), carbon sequestration, soil erosion prevention, and afforestation [25][26][27]31]. Acrocomia palms could, for example, be part of riparian or stream buffers and be cultivated on degraded lands [26,91]. Available knowledge on cultivation systems and plant spacing, plant nutrition and protection, as well as harvest and post-harvest, has contributed to advance the preparedness of acrocomia for cultivation [6].…”

The diversification of biomass resources is key to the transition towards a bioeconomy. Acrocomia spp., a neotropical genus of palms, is an example of plants’ diversity potential for a sustainable bioeconomy. Acrocomia’s adaptability to environments outside rainforests, its specific fruit properties and high yields has generated the interest of researchers and entrepreneurs, triggering its introduction as a multipurpose oil crop. Developing sustainability-oriented and knowledge-based acrocomia value webs requires a collaborative, systems approach from the outset. Fostering an inter- and transdisciplinary dialogue on acrocomia through a participatory workshop with both academic and non-academic actors contributed to this endeavor. This allowed the identification of priorities, knowledge gaps, and stakeholder roles, and served as the basis for the co-creation of a research and development roadmap. Key steps for the introduction of acrocomia include intertwined technical aspects relating to the development of planting material, cultivation systems, processing technologies and applications, market entry, and value web governance aspects. A broad collaboration among scientists, the public and private sectors, farmers, and civil society, is required for the development of acrocomia value webs. The incorporation of sustainability and a consideration of context in the design and development phases are fundamental to fostering the sustainable performance of acrocomia value webs.

“…Interest in the CEC of organic materials comes from an established direct relationship between soil productivity and soil CEC. The CEC contribution from organic materials is particularly important for the soils of tropical regions, where organic matter is responsible for up to 80% of the CEC in the soils (Pacheco and Petter 2011).…”

Coffee industry waste-derived biochar: characterization and agricultural use evaluation according to Brazilian legislation

et al. 2021

The agricultural use of biochar has been the focus of much research in the last decade due to the improvement of soil chemical, physical, and biological attributes. Nonetheless, Brazil still has no specific legislation for biochar, limiting its agricultural use.The objective of the present work is to evaluate the use of biochar produced from spent coffee grounds (SCG) and coffee parchment (CP) by slow pyrolysis at 700 °C according to the existing framework of the Brazilian Ministry of Agriculture, Livestock, and Food Supply (MAPA) legislation for organic fertilizer, soil conditioner or plant substrate. Biochar was characterized according to normative instructions No. 17, 31, 61, 7, 5 and 35. Although not required by the addressed legislation, the semitotal content of macro-and micronutrients was also determined. While CP biochar could be used as an organic fertilizer or plant substrate, SCG biochar, due to its higher Ni content and lower than required cation exchange capacity (CEC), did not meet MAPA legislation criteria to allow for its agricultural use. Future regulations can be based on the current standards, and structural attributes, such as total C content, particle size distribution, and complete macroand micronutrient determination should be included. Further research may also indicate the viability of biochar use as a soil conditioner based on a more representative set of biomasses with a higher CEC. These considerations will help to take advantage of the benefits of biochar to soil, contributing to a circular economy, which is still at a difficult stage in Brazil.
