Summary: A new diffusion model is proposed to simulate nutrient release from coated fertiliser particles at all stages. The model is universal and can predict the release rate and pattern for all types of coatings given a diffusion mechanism. The model considers nutrient diffusion in the solution within the coating layer, depending on the moisture content and counter diffusive flux of moisture. Experimentally verified with urea release data, the model adequately describes nutrient release from polymer-coated urea.

Summary: In this study, three carbazole-triphenylphosphine hybrids were designed and synthesized to achieve high efficiency and long lifetime of organic room temperature phosphorescence (RTP). The para-substituted pCzTPP showed high RTP efficiency (>10%) and extended lifetime (>600 ms), surpassing the ortho- and meta- isomers. Theoretical simulation and photophysical investigation revealed that the strong intermolecular p-p and p-p interactions in pCzTPP facilitated the transition probability and triplet stability of (3)pp state, demonstrating the synergy of p-p and p-p in RTP process.

Summary: This report introduces a groundbreaking technique for synthesizing carbon dots that exhibit both delayed fluorescence and room-temperature phosphorescence. These carbon dots, synthesized through a straightforward solvent-thermal reaction followed by thermal treatment, demonstrate blue fluorescence and cyan afterglow simultaneously. With an afterglow quantum yield of up to 60.47%, these non-metallic carbon dots exhibit an expected level of afterglow for materials of their kind. Additionally, the average afterglow lifetime is 1.11 s, with a visually recognizable period of 16 s. The practical application of these carbon dots in cutting-edge fields such as anti-counterfeiting security and optical information storage is also demonstrated.

Summary: Fertilizer plays a vital role in agriculture by increasing crop productivity and preventing starvation, but its application can have negative impacts on the environment and human health. Slow/controlled release fertilizers have been developed to minimize these effects, but there is still a lack of understanding in the terminology, classification, and scientific knowledge in this field. This review examines 109 patents related to controlled release urea and highlights the overlooked scientific knowledge, aiming to provide new resources and promote the development of slow/controlled release fertilizers in the future.

Summary: The study focuses on enhancing wheat nitrogen utilization efficiency (NUE) by coating urea with different polymers and potassium iodide (KI). The findings suggest that the treatment with Gum Arabica (GA) and KI significantly improves wheat grain yield, N uptake, and apparent N recovery, highlighting the synergistic effect of K on N availability. This approach could be recommended for improving crop production and reducing environmental nitrogen losses.

Summary: The fast weathering and intensive agricultural practices in tropical areas have led to the degradation of soil fertility. Biochar has been found to be an effective soil amendment for improving crop productivity in highly weathered tropical soils. However, further development is needed to reduce the production and application costs of biochar, and policy decisions are necessary to link economic benefits with social and environmental issues.

Summary: This study explored cost-effective and eco-friendly strategies for native soil phosphorus (P) solubilization, including using silicon (Si)-rich agro-wastes as a Si source and phosphate solubilizing microorganisms (PSM). The results showed that both strategies significantly increased the solubility of P in the soil, as well as the activity of soil enzymes and microbial biomass P. These findings suggest that utilizing agro-wastes as Si sources can complement expensive P fertilizers and address waste disposal issues in a sustainable manner.

Summary: Conversion of forest land uses to agriculture in Ranchi, India leads to a decrease in soil organic carbon (SOC) pools and affects soil aggregation and aggregate-associated carbon accumulation. The SOC concentration in native forest land is significantly higher than in rice-wheat, rice-vegetable, and maize-wheat land uses. Tillage and regular crop removal result in a loss of SOC contents in the surface layers and carbon storage within aggregates.

Summary: The management of rice straw in south Asia is a challenge. This study found that the application of rice straw and phosphorus solubilizing microbes (PSMs) can solubilize fixed phosphorus in the soil, improve the yield of wheat, and increase organic acid and enzyme activity in the rhizosphere. The recommended application rate is 12 Mg ha-1 of rice straw and PSMs plus 75% mineral phosphorus fertilizer to save 25% of phosphorus fertilizer without affecting yield.
