Abstract Leaching losses of N are a major limitation crop production on permeable soils and under heavy rainfalls as in the humid tropics. We established field trial central Amazon (near Manaus, Brazil) order to study influence charcoal compost retention N. Fifteen months after organic‐matter admixing (0–0.1 m soil depth), we added 15 N‐labeled (NH 4 ) 2 SO (27.5 kg ha –1 at 10 atom% excess). The tracer was measured top m) plant samples taken two successive sorghum ( Sorghum bicolor L....
Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level scientific understanding (LOSU) regarding consequences application to soil were explored. Five broad thematic areas addressed: biodiversity and ecotoxicology, organic matter greenhouse gas (GHG) emissions, physical properties, nutrient cycles crop production, remediation. highest biochar’s effects soils were:...
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure greater sustainability commodity value chains. This includes the to establish new crop plantations and pasture areas on already deforested land so that forest clearing agriculture minimized. Where tree crops are planted as part agroforestry systems land, this amounts form re-agro-forestation which can generate environmental benefits in addition production. Here, we discuss case...
Anthrosols known as Amazonian Dark Earth (ADE) have borne witness to the intensification of sedentary patterns and demographic increase in Central Amazon. As a result, recurring pattern has been observed mounds with ADE arising from domestic activities disposal waste. The objective this research was demonstrate relationship these anthropic pedogenetic formation processes municipality Iranduba, Brazil. Disturbed undisturbed soil samples were taken two areas (pretic horizon) non-anthropic...
Soil ecosystem service (SES) approaches evidence the importance of soil for human well-being, contribute to improving dialogue between science and decision-making encourage translation scientific results into public policies. Herein, through systematic review, we assess state art SES in tropical regions. Through this 41 publications were identified; while most these studies considered SES, a lack consistent framework define was apparent. Most measured natural capital processes, only three...
Abstract We assessed substrate‐induced respiration and soil chemical properties in order to study the influence of charcoal, nitrogen phosphorus fertilisation on two different perennial crops a confounded factorial design highly weathered Amazonian upland soil. Each plantation tested three factors levels making up 27 (3 3 ) treatment combinations. Whereas banana received mineral addition charcoal applications rd factor), guarana (Paullinia cupana) was fertilised organically using chicken...
Amazonian Dark Earths (ADE), one of the best-known examples anthropogenic (man-made) soils, are result Amerindian settlements in pre-Columbian period. ADE highly variable terms their size, shape, depth and physical chemical make-up. Scholars tend to divide into two categories: terra preta mulata. The former dark fertile soils replete with ceramic shards, indicating areas habitation, while latter lighter colour, less fertile, lacking pottery thought be old agricultural fields. While a...
Organic matter plays an important role in many soil properties, and for that reason it is necessary to identify management systems which maintain or increase its concentrations. The aim of the present study was determine quality quantity organic C different compartments fraction Amazonian ecosystems. (FSOM) fractionated stocks were estimated primary forest (PF), pasture (P), secondary succession (SS) agroforestry system (AFS). Samples collected at depths 0-5, 5-10, 10-20, 20-40, 40-60,...
ABSTRACT The soil carbon under Amazonian forests has an important roles in global changing, making information on the content and depths of these stocks are considerable interest efforts to quantify emissions atmosphere.This study quantified organic stock primary forest up 2 m depth, at different topographic positions, Cuieiras Biological Reserve, Manaus/ ZF2, km 34, Central Amazon, evaluating attributes that may influence permanence carbon. Soil samples were collected along a transect 850...
The partitioning of rain water into throughfall, stemflow and interception loss when passing through plant canopies depends on properties the respective species, such as leaf area branch angles. In heterogeneous vegetation, tropical forest or polycultural systems, presence different species may consequently result in a mosaic situations with respect to quantity quality inputs soil. As these processes influence not only availability for plants, but also infiltration nutrient leaching,...
Resumo O objetivo deste trabalho foi avaliar os efeitos de diferentes usos da terra nas características e nos atributos Latossolos região Oeste do Estado Bahia. Os apresentavam texturas com fração areia amplamente predominante, foram avaliados em áreas cerrado, algodão, soja feijão, no Município Luís Eduardo Magalhães. A caracterização morfológica a coleta amostras solos para avaliação dos físicos químicos por horizontes feitas minitrincheiras, enquanto condutividade hidráulica saturada...
