Summary: In citrus orchards in central China, reducing N fertilizer input and planting green manure are dominant measures for improving N use efficiency. This study found that reducing N fertilizer input can decrease total N losses but increase total P losses. Planting green manure can reduce total N losses but increase both total N and P losses during the ground mulching stage.

Summary: Research showed that phosphorus fertilizer use efficiency in cereal crops is influenced by climate, soil, and management factors. The phosphorus content in aboveground biomass increased by 12.4% of the applied fertilizer, with lower PFUE in maize compared to rice and wheat, and lowest in soil with near neutral pH. There is great potential for improving PFUE in cereal crops.

Summary: The development of robust nutrient management strategies is crucial for improving crop productivity, profitability, and nutrient use efficiency. Managing nitrogen and potassium application rates is critically important in wheat-based production systems to maximize profitable production with minimal negative environmental impacts. This study investigates the effects of different fertilizer-N and fertilizer-K application rates on wheat productivity, nutrient use efficiency, and profitability. The results show that moderate nitrogen application significantly increases wheat productivity and nutrient uptake efficiency, while the interaction effect between nitrogen and potassium application is not significant.

Summary: This study investigates the shoot and tuber biomass as well as nutrient use efficiency of white Guinea yam under different soil NPK conditions. The results show that genotypes exhibit variations in response to soil NPK conditions, nutrient uptake, and nutrient use efficiency. The study also reveals that NPK fertilization does not negatively affect tuber quality. These findings contribute to breeding programs for the development of improved yam varieties.

Summary: Nanomaterials have attracted attention in agriculture because of their unique characteristics. Nanomaterials, such as nanofertilizers, have the potential to improve crop nutrient management and reduce environmental nutrient losses. However, metallic nanoparticles can be toxic to soil biota. The organic nature of nanobiochar may help overcome this toxicity and maintain the benefits of nanomaterials.

Summary: Straw return can improve soil phosphorus availability, reduce mineral phosphorus fertilization, and increase phosphorus apparent recovery efficiency for cotton production. However, it does not significantly affect seed cotton yield in a continuous barley-cotton rotation system on coastal saline soil.

Summary: Short-cycle horticulture crops often use fertigation, which can lead to the leaching of nutrients, especially phosphorus, into waterways. This study examines the incorporation of activated aluminum into container substrates as a method to reduce phosphorus loss and investigates its effects on nutrient content and growth of a short-cycle crop. The results show that the addition of activated aluminum significantly reduced phosphorus leaching without affecting crop growth or quality. This study demonstrates the effectiveness of incorporating activated aluminum in reducing environmental phosphorus loss.

Summary: Phosphorous (P) fixation in saline soils is a global concern. This study investigated the effects of different P sources and rates on winter wheat yield, P uptake, agronomy efficiency, and soil quality in the coastal saline area of China. The results showed that optimizing P sources and rates, with superphosphate (SSP) being the most effective source, can significantly improve wheat yield and P uptake.

Summary: The European dairy industry generates large volumes of wastewater from milk and dairy food processing. Removal of phosphorus through complexing with metal cations is a potential source for agricultural reuse, but there is limited knowledge on the plant availability of this complexed P. The study found significant variations in P availability from dairy sludge depending on treatment process, highlighting the importance of having P availability information to ensure proper application rates without environmental risk.

Summary: Mixed cropping of cereals and legumes can benefit from complementary utilization of resources, especially under conditions of phosphorus deficiency. This study found that the performance of cereal-legume mixtures can be independent of external phosphorus supply and may even outperform sole cropping of maize or sorghum in terms of yields and phosphorus uptake.

Summary: This study investigated the transcription patterns of PAPs in poplar under P shortage, identifying distinct P responsive expression patterns in roots and leaves for 23 PAPs. Activities of root-surface PAPs were found to increase significantly under low P availability, and proteomic analyses revealed three newly secreted proteins under P shortage, suggesting a central role of PtPAP1 in enhanced P acquisition from organic sources.

Summary: Soil salinity is a critical issue for rice production and is often linked to phosphorus deficiency. Plant hormones such as brassinosteroids have been shown to play a role in plant response to stress. This study compared the growth and root characteristics of two rice cultivars under salt stress, phosphorus limitation, and brassinosteroid treatment. The results showed that salt mainly affected root size and extent, while phosphorus supply mitigated the negative effects of salt on root growth in one of the cultivars. Brassinosteroid treatment had minimal impact on plant development in both experiments. Root traits may be useful for selecting salt-tolerant and phosphorus-efficient rice cultivars.

Summary: Root and shoot biomass decreased with decreasing phosphorus supply, and root-to-shoot ratio increased. Shoot phosphorus concentration decreased steadily, while root phosphorus concentration remained constant below 0.5 mM of phosphorus. Root-associated and intracellular acid phosphatase activity increased with higher levels of phosphorus deprivation, with higher activity in the Kuba cultivar than in Cardoso.

Summary: Legume catch crops can significantly increase arbuscular mycorrhiza formation of subsequent barley crops, with serradella showing a stronger impact than fertilization treatments. Serradella enhances phosphodiesterase activities and decreases β-glucosidase activities in soil, while plant availability of P is not significantly affected. These findings suggest that even non-host catch crops can promote mycorrhiza formation and P mobilization in soil for subsequent main crops.

Summary: Drought is a pressing issue worldwide, and selecting wheat genotypes adapted to changing climatic conditions is crucial. This study evaluated 156 bread wheat genotypes, including landraces and modern varieties, under different drought treatments. The results showed that landraces had higher yield stability and protein content under drought stress, suggesting their potential for developing drought-tolerant modern wheat varieties. Effective utilization of landraces in breeding programs is important for developing climate-resilient wheat varieties.
