“…Ca/P ratio ranges from 0.4 to 1.6 in ADE, 3.6 to 18 in other ADEs (Fig. 6) (Costa and Kern, 1999;Silva et al, 2012), 2.0 to 3.3 in bones (Schaefer et al, 2004;Almeida et al, 2008), above 14 in wood ashes and charcoal (Wilson et al, 2008;Okmanis et al, 2015), and below one in human faeces (Rose et al, 2015;Torri et al, 2017). The low Ca/P ratio in the ADE of this study may be due to its higher clay content (Schaefer et al, 2004;Macedo et al, 2017) compared to other ADEs (Costa and Kern, 1999;Silva et al, 2012).…”

Amazonian Dark Earths (ADEs) are soils studied for archaeological purposes and as a potentially agricultural model for the humid tropic. We investigated the chemical composition of an ADE in comparison to an adjacent Ultisol without anthropic influence for better understanding the origin of ADE fertility and formation process. Three hundred ADE and Ultisol samples were collected at 10 cm depths from 0 to 100 cm soil profiles on the Caldeirão site at the Solimões River, Brazil and analyzed for elemental composition in an inductively coupled plasma mass spectrometer (ICP-MS). Results showed significantly increased concentrations of P,

“…The literature has much information on the management of biomass ash and its effect on soil properties 73 – 75 , not least as a way of replenishing essential nutrients and for modifying soil structure/microstructure. The very nature of plants to accumulate metals shows there is a key relationship between soil chemistry/mineralogy and the ‘needs’ of individual plants.…”

This work is part of a study of different types of plant-based biomass to elucidate their capacity for valorisation via a managed carbonation step involving gaseous carbon dioxide (co 2). the perspectives for broader biomass waste valorisation was reviewed, followed by a proposed closed-loop process for the valorisation of wood in earlier works. the present work newly focusses on combining agricultural biomass with mineralised co 2. Here, the reactivity of selected agricultural biomass ashes with co 2 and their ability to be bound by mineralised carbonate in a hardened product is examined. three categories of agricultural biomass residues, including shell, fibre and soft peel, were incinerated at 900 ± 25 °C. The biomass ashes were moistened (10% w/w) and moulded into cylindrical samples and exposed to 100% CO 2 gas at 50% RH for 24 h, during which they cemented into hardened monolithic products. the calcia in ashes formed a negative relationship with ash yield and the microstructure of the carbonate-cementing phase was distinct and related to the particular biomass feedstock. this work shows that in common with woody biomass residues, carbonated agricultural biomass ash-based monoliths have potential as novel low-carbon construction products. This paper discusses environmental issues that are of relevance to the sustainable use of resources and protection of the environment. By re-using abundantly available agricultural biomass residues, and by reducing the amount of cement used in construction and their associated carbon emissions, significant potential sustainability gains can be realised. In consideration of this, a low carbon management option for biomass residues is proposed. Agricultural activities generate huge volumes of biomass residues, with crop derived waste accounting for 94% of global biomass production 1. These include cereals (wheat, rice, maize, and barley), sugarcane, soybean, and some oil crops, fruits, vegetables, roots and tubers, and sugar beet 1. These residues are expected to increase as the world's population exceeds 11 Billion by 2,100 2. It is estimated that globally 140 Gt of agricultural residues are generated each year 3,4. According to Lal (2019) 5 , the total annual amount of crop residue produced globally is estimated at 2.8 Gt for cereal crops, 3.1 Gt for 17 major cereals and legumes, and 3.8 Gt for 27 common food crops. The IEA CCC (2015) 6 reports the global resource for unexploited cereal crop residues amounts to 517 Mt. The FAO (2002) 7 projects that from 1999 to 2030, the agricultural sector of developing countries will increase by 13% or 120 M ha. Predictions for global cereal yield suggest an increase in the range 0.9% per annum over the period 2005/2007-2050, continuing a trend of long-term declining yield growth (20 y average yield increase declined from ~ 3% pa in 1982, to ~ 1% by 2005) 8,9. The intensification of agricultural and increased crop yield (producing more per unit of land) will undoubtedly raise crop residue production 10. A positive correlation exists betw...

In the Northern Hemisphere, the Younger Dryas cooling occurred between 12.8 and 11.7 ka bp. This cooling is thought to have been the result of an abrupt change in atmospheric and oceanic circulations. One of the hypotheses explaining such a change suggests that just before the onset of the Younger Dryas cooling, multiple airbursts/impacts occurred over the Northern Hemisphere. We studied the late Pleistocene sediments from the Netherlands and Belgium to check whether a sudden short event might have taken place just before the onset of the Younger Dryas cooling. The geochemical features revealed suggest that such events might have occurred. The presence of products of biomass burning is suggested on the basis of trace element features of sediments from the lower Younger Dryas boundary. The presence of a volcanic component and a component resulting from extensive biomass burning in the sediments of c. 12.9 ka bp are indicated on the basis of trace element features. The volcanic component may be related to the Laacher See volcano eruption, whereas the cause of the extensive biomass burning remains unclear.
