10 Οκτ 2024 · The first two principal components accounted for 75.2% (PC1 = 57.9% and PC2 ... Supplementary Figs. 3–5). We calculated the weighting values of ... Warming can promote plant carbon ...
4 ημέρες πριν · In soil environment, pH and soil organic carbon are very important parameters that control the movement of different elements in soil (Islam et al., 2016). ... and (d) SOM map of sampling sites in soil physicochemical properties and trace elements 3.4 Quantifying sources of soil trace elements The PCA was adopted to elucidate the inter-elements ...
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 ...
19 ώρες πριν · There are many other indicators of plant carbon sinks, and while we have captured one characteristic of dense vegetation growth in low mountain and hilly regions, there may be other characteristics.
3 ημέρες πριν · We use experiment as the fixed effect because two experiments vary in the amount of nitrogen added through time and one had multiple addition levels that were all low compared to the other experiments. We only performed this analysis for abundance change. All data management and analysis were performed using R 4.2.2 (RCoreTeam 2022).
8 Οκτ 2024 · Variation in atmospheric CO 2 concentration (blue), maximum carboxylation rate (V cmax, purple, a) and maximum electron transport rate (J max, yellow, b) of C 3 plant species during the last 80 Myr before presence. V cmax and J max per time were quantified as median values for plant species which originated in the respective time intervals of 5 Myr. . Variation is depicted along the time axis ...
List the essential elements required by plants and summarize their functions. Describe how plants obtain nutrients, including the mechanism of cation exchange. Distinguish between macronutrients and micronutrients.
