Summary: The study demonstrated that high biopore abundancies have the potential to improve both belowground and aboveground biomass, with dry conditions leading to improved root exploration and hydration, and moist conditions resulting in enhanced plant growth and nutrient uptake. The availability of subsoil water and the influence of earthworms on soil nutrients play crucial roles in these processes.

Summary: This study investigates the effects of different nitrogen (N) levels on the uptake and translocation of organophosphate esters (OPEs) by watermifoil (Myriophyllum aquaticum). The results indicate that N levels can alter the uptake, accumulation, and translocation of OPEs in M. aquaticum, with low concentrations of N promoting OPE uptake and high concentrations inhibiting plant growth and OPE accumulation. Additionally, physicochemical parameters, substituents, and structures of OPEs also play a role in their accumulation and translocation in M. aquaticum.

Summary: Root hairs play an important role in nutrient uptake in plants, especially in soils with high sorption capacity. Mutants with defective root hairs may have lower nutrient uptake unless they compensate with increased root growth. Root traits show high plasticity in response to soil texture, with differences in root to shoot ratio and adaptation of plants to different soil types impacting plant growth and nutrient uptake.

Summary: This study investigates the effects of biochar amendment, nitrogen and phosphorus supply on soybean growth and nutrient uptake. The results show that biochar application significantly increases soybean biomass and enhances the symbiotic performance of Bradyrhizobium japonicum. Additionally, biochar improves nitrogen uptake and has a positive correlation with shoot and root biomass.

Summary: In Caryophyllales species, there is no correlation between shoot and root sodium concentrations in species with normal shoot sodium levels, but a positive correlation in species with abnormally high shoot sodium levels. Additionally, species with abnormally high shoot sodium levels have higher shoot/root sodium concentration ratios than species with normal shoot sodium levels.

Summary: The increasing duration of waterlogging has significant impacts on corn plants, leading to decreases in whole-plant dry weight, leaf area, and root volume, while leaf number and plant height are less affected. Root forks are the most sensitive parameter after prolonged waterlogging, declining by a substantial percentage in both experiments.

Summary: Fertilisation with various concentrations of monopotassium phosphate affected rose growth, flower production and nutrient accumulation differently; concentrations of 0.0 to 3.0 g/L significantly increased plant growth and nutrient uptake, while concentrations of 4.0 or 5.0 g/L led to a decrease in these parameters.

Summary: This study investigated the effectiveness of the fungicide Sedaxane as a seed treatment for oilseed rape. The results showed that all fungicide treatments, especially Thiram, greatly reduced the presence of Rhizoctonia DNA. Seedlings treated with Sedaxane exhibited significant root biostimulation in the presence of Rhizoctonia.

Summary: To reduce the transfer of cadmium to the food chain, it is important to select wheat germplasm with low cadmium accumulation and develop management practices that decrease cadmium uptake. This study investigated variations in cadmium accumulation, translocation, and distribution in two wheat cultivars in response to cadmium stress and supplemental silicon. The results showed that supplemental silicon reduced cadmium uptake and accumulation, and the differences in cadmium accumulation between the wheat cultivars were related to cadmium translocation and subcellular distribution.

Summary: Improving sulfur and water use efficiency for peanut cultivation on sandy soils remains a challenge. By studying partial sulfur balance in irrigated peanut crops in Central Vietnam, it was found that sulfur application rates of 30-45 kg S ha(-1) showed positive sulfur balance and maximum pod yield.

Summary: Managing phosphorus is a global priority for environmental water quality. A study in Western Australia's Fitzgerald River catchment found that dissolved phosphorus transport was dominant, with physical filtering methods like riparian vegetation proving ineffective in restricting phosphorus transport into streams. Evidence-based fertiliser advice could help reduce dissolved reactive phosphorus losses without yield loss.

Summary: In a wheat-mungbean-rice rotation system, nitrous oxide emissions were higher in strip tillage compared to conventional tillage, with the nitrogen fertilizer rate also affecting emissions. However, strip tillage could improve soil aggregation and balance nitrogen and crop yield despite the increased emissions.

Summary: The study found that reducing soil disruption and increasing residue deposition from previous crops can reduce weed abundance and biomass in wheat-mungbean-winter rice and monsoon rice-mustard-winter rice rotations under conservation agriculture. Furthermore, under conservation agriculture, weed seeds were mainly concentrated in the 0-5 cm soil depth.

Summary: Transitioning to minimal tillage and increased crop residue retention in an intensive rice-based cropping system in the Gangetic Plains of South Asia can significantly increase the accumulation of soil organic carbon (SOC) and total nitrogen (TN). Compared to conventional crop establishment practices, zero tillage, strip-tillage, and bed planting can more effectively sequester SOC and TN, leading to higher soil levels of SOC and TN.

Summary: The shift from conventional tillage to conservation agriculture practices may make weed control more challenging initially, but over time, the weed seedbank may be altered. Continuous conservation agriculture can reduce the size of the weed seedbank, but lead to an increase in specific perennial weed species.

Summary: Land development is occurring rapidly on sand-dominant soils in the Lower Mekong Basin, but it poses risks of degradation. Agriculture expansion on sloping uplands and intensification of cropping on lowland landscapes are the main factors contributing to these risks. Challenges include drought-prone conditions, nutrient losses, waterlogging, and soil acidity. These constraints limit the productivity and sustainable use of sand profiles. However, site-/soil-specific management strategies, land suitability assessment, and conservation agriculture principles can help overcome these constraints.

Summary: The study found that waterlogging for 24 hours did not affect sunflower at any stage, but waterlogging for 48 and 72 hours suppressed emergence and growth at the 2 and 4-leaf stages. Waterlogging for 72 hours completely prevented emergence for early-sown sunflower, while emergence was less affected for later sowing. Shoot and root dry weight were most affected at the emergence and 2-leaf stages, not at the 4-leaf stage.
