2 ημέρες πριν · As a relatively stable form of soil organic carbon (SOC), humus carbon is a key component that supports soil ecosystem functions, playing a crucial role in carbon sequestration and stabilization [1,2].Adding additional SOC to the soil is considered a potential approach to improving soil quality [].Crop straw is rich in [] organic carbon, nitrogen, phosphorus, potassium, and trace nutrients [].
19 ώρες πριν · From Table 3, it can be seen that the forest cover of the study reached 55% and the land of forest type decreased from 1646.76 km 2 to 1634.33 km 2 and then increased to 1641.32 km 2.
10 Οκτ 2024 · The first two principal components accounted for 75.2% (PC1 = 57.9% and PC2 = 17.3%) and 59.8% (PC1 = 35.8% and PC2 = 24.0%) of the cumulative percent variability in soil health at 0–5 cm and 5 ...
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 ...
TG was a carbon source, whereas SACF and TRF were carbon sinks. The influence of air temperature on RE and GEE was greater than that of soil temperature, but the influence of soil moisture on...
19 ώρες πριν · A matrix contained the values of content of Zn in harvest 1 (Zn_H1), harvest 2 (Zn_H2), and harvest 3 (Zn_H3), and the average of the three harvests (Zn_average) was selected. Figure 4 shows the space defined by PC1 and PC2 (which capture 85.85% of variance) with the score values of the samples. The first component explained the 57.13% of the ...
4 ημέρες πριν · The detection limit values of elements in flame AAS were found to be 0.15 µg/kg for Mg, 3 µg/kg for K, 1.5 µg/kg for Ca, 5 µg/kg for Fe, 1.5 µg/kg for Cu, 1.5 µg/kg for Mn, and 1.5 µg/kg for Zn. 2.4 Environmental and ecological indices for soils The present study included evaluating trace element contamination levels and ...
