Summary: The study demonstrates that enhanced-efficiency fertilizers could potentially reduce NH3 emissions from urea-based fertilizers in green sugarcane fields without affecting sugarcane yield. The results indicate that sugarcane yields were similar across different nitrogen sources at two sites.

Summary: This study investigates the effects of the nitrogen stabilizers DMPP and NBPT on soil microbial communities. The results show that long-term application of DMPP and NBPT can reduce nitrous oxide emissions, and DMPP can decrease the diversity of ammonia oxidizers. Long-term urea application increases the potential nitrification rate of ammonia oxidizers, while DMPP weakens this effect.

Summary: Tropical pastures face challenges in responding to nitrogen fertilization due to ammonia volatilization loss on the soil surface. This study evaluated the effects of different nitrogen sources and rates on ammonia volatilization loss and shoot dry weight yield of Urochloa decumbens. The results showed that urea had the highest ammonia volatilization loss, while ammonium nitrate and urea treated with urease inhibitor had the highest shoot dry weight yield. Increasing nitrogen rates resulted in higher shoot dry weight yield, while the detrimental effects of ammonia volatilization loss were more pronounced under limited nitrogen supply conditions.

Summary: This study introduces a paper-based analytical device (UrePAD) for colorimetric determination of urease activity in soils, offering advantages such as low cost and simplicity in handling. The results showed that UrePAD was effective in determining urease activity and screening inhibitors in various soil samples and urease inhibitors.

Summary: The study investigated the inhibitory effects of two major constituents of Chamomile on soil urease activity and NH3 volatilization. Results showed that 2-Cyclopenten-1-one and Eugenol could effectively inhibit urease activity and reduce ammonia emissions, especially in acidic soil. Molecular docking studies confirmed the inhibition mechanisms, highlighting the potential of these natural compounds as urease inhibitors to increase fertilizer N use efficiency.

Summary: The experiment showed that variations in soil pH affect mesotrione adsorption, in turn impacting crop susceptibility; crop visual injuries, chlorophyll fluorescence, and dry biomass reductions were more severe at neutral pH (7.0) compared to acidic pH (5.0); as mesotrione residues increased, crop damage increased gradually.

Summary: Urea granule dissolution in soil and soil urease activity are crucial for accurately predicting nitrogen dynamics after urea application. This study investigated the dissolution of urea granules and the activity of urease in soil under different temperatures. The results showed that soil moisture was the dominant factor at low moisture contents, while temperature controlled the dissolution process at higher moisture levels.

Summary: In this study, N-(n-butyl)-thiophosphoric triamide (NBPT) was used to address the issue of enzyme induced carbonate precipitation (EICP) solidification at high temperatures. The effects of NBPT concentration and temperature on sand column solidification efficiency were studied, and it was found that NBPT addition improved the homogeneous distribution of calcium carbonate and increased the strength of the solidified sands.

Summary: Biochar has different effects on urease activity and nitrogen content in different soil types. It enhances urease activity by stimulating urease-producing microorganisms and increasing soil pH. However, in some cases, biochar may lead to an increase in nitrogen loss.

Summary: The study found that at low boron supply, plants fed with nitrate and ammonium had similar B-10 uptake rates, accumulation, and xylem B-10 concentrations, but these attributes were reduced at high boron supply. Ammonium-induced acidity and nitrate-induced alkalinization led to altered B distribution between roots and shoots as well as different B transport mechanisms in plants.

Summary: This study introduces a new soil improvement method involving the use of urease inhibitor N-butyl-thiophosphoric triamide (NBPT), which increases calcium carbonate precipitation and enhances soil mechanical properties. Laboratory tests demonstrate that the suitable dosage of NBPT can effectively improve soil quality and accelerate the MICP process.

Summary: The study found that coptisine can significantly inhibit the activity of ruminal bacterial urease, reducing the release of ammonia and decomposition of urea, thereby improving microbial fermentation in the rumen system. Coptisine may interact with both the urease active center nickel and amino acid residues possessing sullhydryl groups.

Summary: The addition of urease inhibitors (NBPT) and sulfur-coated urea (SCU) in peanut cultivation can effectively reduce nitrogen release, increase photosynthetic rate, promote root development and nitrogen absorption, improve nitrogen use efficiency, and have a positive impact on microbial activity and yield of peanuts.

Summary: An uncontrolled flooding episode resulted in ecological damage and necrosis of plant tissues in a wetland with high levels of arsenopyrites. The willow species Salix aurita L. was able to survive in this environment, but individual plants showed varying levels of toxicity-induced damage. The study compared the phenotypic responses of the willows with their biochemical status and rhizosphere physiological parameters.
