Summary: Enhanced nitrogen and water uptake from deep soil layers can increase resource use efficiency for winter oilseed rape. Low nitrogen supply can reduce water uptake throughout the soil profile and alter water uptake distribution, while water deficit in the upper soil layers can lead to compensatory deep water uptake. The findings highlight the importance of deep roots for water uptake and the potential benefits of reducing nitrogen supply for mitigating nitrogen leaching and altering water uptake from deep soil layers.

Summary: The study shows that eucalypt farmers in Minas Gerais, Brazil are more inclined to adapt to drought by reducing the length of the eucalypt rotation, while reducing density is the least chosen option, indicating a potential underestimation of its benefits. The preference for reducing the length of the eucalypt rotation is particularly strong among the most vulnerable farmers in the sample, highlighting a clear segmentation in farmers' choice behavior.

Summary: The study found that deciduous trees maintain a high level of nitrogen uptake throughout the non-growing season, challenging the traditional view that deciduous trees remain dormant during this time. Soil nitrogen transformation remained active in winter, with microbial nitrogen immobilization reaching its peak in late winter. Evergreen and deciduous trees showed higher uptake rates for NH4+ and glycine than NO3- and tyrosine, while deciduous shrubs and herbs preferred NO3- over other forms of nitrogen.

Summary: Our study evaluated the effects of Acacia auriculiformis agroforestry fallows on impoverished sandy soils of the Bateke Plateau in the Democratic Republic of the Congo. The results showed that agroforestry fallows had better physico-chemical properties and higher soil carbon stocks compared to traditional savanna fallows. However, the establishment of agroforestry fallows resulted in a decrease in soil pH.

Summary: Si availability may affect the uptake and assimilation of different forms of inorganic N by plants. This study found that bamboo had higher inorganic N root uptake and assimilation rates compared to other species. Si supply did not change the overall uptake and assimilation rates, but it slightly increased NO3--N uptake and assimilation rates in some species. These findings have implications for coexistence and competition between bamboo and other trees.

Summary: The study found that plants in nutrient-poor soils have a competitive advantage over microorganisms in nitrogen uptake, both during the day and at night. The diurnal dynamics had minimal impact on microbial nitrogen uptake.

Summary: The processing of nitrogen in forest canopies can impact short-term leaf nitrogen supply and photosynthesis, but not long-term nitrogen retention. There were no significant differences in plant biomass, nitrogen concentration, and leaf nitrogen resorption between canopy and soil nitrogen applications. This highlights the importance of considering canopy nitrogen processing for accurately predicting the impact of nitrogen deposition.

Summary: This study quantified the distribution of nitrogen, dry-matter, and soil-applied (15)N in different compartments of five naturally-growing oak trees. The results showed that the xylem rings compartment contained the most biomass, while branches and coarse roots contained the most nitrogen. The labeled (15)N was found in all compartments except the heartwood, with the majority being in the leaves. Overlooked compartments such as coarse roots, stumps, xylem, and other branches accounted for a significant portion of the (15)N recovery. The study also revealed that (15)N was present in all sapwood rings, with more being found in younger rings compared to older ones. The (15)N allocated to ancient rings could originate from various sources, including direct uptake from the soil, autumnal resorption from leaves, or transport through ray parenchyma. Additionally, the study confirmed the role of microbial biomass as a nitrogen sink in forests.

Summary: The use of anaerobically digested swine manure in farmland can stimulate nitrification and denitrification, with nitrification still dominating. Increasing levels of anaerobically digested swine manure can enhance the production of N2O through nitrification and denitrification, with the highest N2O production observed in the 25 g center dot kg(-1) treatment. Therefore, when studying the impact of anaerobically digested swine manure on N2O emissions, the influence of soil moisture content needs to be considered.

Summary: Acacia mangium was widely planted in the 1990s for afforestation in Sarawak, but it is now being devastated by fungal diseases. Genetic variability is limited, making selection for resistance or tolerance difficult. However, hybridisation with A. auriculiformis has shown promise in Vietnam, with resistant hybrids that can be easily propagated. Eucalypts, such as E. pellita and E. deglupta, are a good option for equatorial climates like Sarawak, with easy hybridisation and vegetative propagation.

Summary: Drought under global change poses a threat to plant growth and nutrition. This study investigated the role of arbuscular mycorrhizal fungus in plant uptake of nitrogen from different sources along a soil moisture gradient. The results showed that mycorrhizal plants had a higher uptake of nitrogen compared to nonmycorrhizal plants, and this advantage was observed across different moisture levels.

Summary: This study investigated the effects of different forms of nitrogen treatment on the uptake of fluoranthene by rice and wheat, and found that ammonium-treated rice and nitrate-treated wheat accumulated the most fluoranthene under an equivalent nitrogen supply. The study also found that fluoranthene accumulation was correlated with plant growth and antioxidant enzyme activities.

Summary: Integrating nitrogen-fixing trees in forest and agroforestry systems in the Congo basin can improve soil health through carbon sequestration and nutrient restoration relative to tropical savannas. This practice also generates a range of ecosystem services and contributes to improving soil health, food security, climate change mitigation, and the objectives of the 4 per 1000 Initiative.
