Litter leachates

WebLeaf litter leachate studies have mostly focused on postsenesced leaves that were abscised off the trees without a disturbance. However, disturbances, such as hurricanes, can cause leaf fall (i.e., greenfall) throughout the year, and thus, understanding the DOM in leaf litter leachate at different phenological stages is important. Web31 mrt. 2024 · Seven sites had historical poultry litter applications; three sites received only commercial P fertilizers. Five sites had no-till or conservation tillage (i.e., turbo tilled to 7.5-cm depth with 30%–60% and 15%–30% residue for corn and soybean, respectively) and a winter wheat (Triticum aestivum L.) cover crop for >5 years (soil health).

WebCamphor, bornyl acetate, and limonene were found in leaf and fresh litter leachates; however, degraded litter did not contain any of these compounds. Camphor was the most common potentially allelopathic compound found in J. ashei leaf and litter leachate and in volatiles from leaf tissue.

WebThe present study aimed to determine the allelopathic effects of leaf litter leachates (LLLs) from Ko and their purified condensed tannins (PCTs) on the germination and growth of Ac by mangrove microcosms. Replicate pots containing five different levels of LLLs and PCTs were separately prepared and propagules of Ac were placed in each treatment. The addition of leachate of each of the four litter species led to higher microcosm respiration rates compared to the addition of water alone already after 2 h of incubation (Fig. 2). At this early stage, net respiration rates in the leachate-amended microcosms ranged from 344 ± 241 µg CO2–C h−1 for … Meer weergeven Litter leachates showed a more than seven-fold difference in DOC concentrations among the four studied tree species, … Meer weergeven Leachate species richness and composition had relatively little effect on any of the response variables across all treatments (Table 3).
