1 ημέρα πριν · The world’s forests cover 4.1 billion ha (31% of the total land area) and contribute 662 Gt of total carbon stock (163 tonnes per ha), which is made up of 300 Gt in soil organic matter, 295 Gt in living biomass, and 68.0 Gt in dead wood and litter (FAO, 2024).Forests and trees have a significant impact on both people and the environment, supporting livelihoods and protecting biodiversity ...
4 ημέρες πριν · In PC1, one important element is Fe which is among the most abundant elements in the Earth’s crust, thus it may be derived from the weathering of rocks and minerals with the physical and chemical interactions and blend of organic matter overlapped on geogenic content in soil (Bodrud-Doza et al., 2016).
19 ώρες πριν · This is mainly due to the high vegetation cover of the low hills in the study area, which is rich in carbon stocks and well protected 45. Water had the lowest NRSEI values in 2014 and 2017. Water ...
2 ημέρες πριν · While numerous studies have examined the effects of direct and carbonized straw return on soil fertility, most focus on short-term impacts. Long-term research is needed to understand how these practices affect soil fertility and organic carbon transformation, providing guidance for the use of straw and biochar in agriculture. This study examined the long-term effects of corn straw (CS), straw ...
Two sequences of different intensity due to even-(the major peak sequence) and odd-C-numbered PAHs (the minor peak sequence) [18] spaced by a mass difference of 24 units, are evident, especially ...
20 Ιουν 2023 · Although each element has unique physical and chemical properties, it will be obvious that certain groups of elements are closely related. Members of each group are more like each other than they are like any member of another group.
19 ώρες πριν · The conversion of spent coffee grounds (SCG) into hydrochars has been the subject of extensive research in recent years, aimed at evaluating their potential for biofortifying foods and mitigating the plant toxicity linked to SCG. This study aimed to assess the physicochemical characterization and the impact of incorporating both activated (ASCG and AH160) and functionalized SCG (ASCG-Zn), as ...
