Hace 5 días · Phosphorus (P) application can enhance soil P availability and alter P fractions. However, the P accumulation and transformation of different P sources in low-phosphorus red soil remain unclear. Two-year (2018–2019) field experiments were conducted to investigate the effects of five P source treatments (CK—no phosphorus; SSP—superphosphate; MAP—calcium–magnesium phosphate; DAP ...
Hace 2 días · In this study, S53P4 (53SiO2–23Na2O–20CaO–4P2O5) bioactive glass (BG) were prepared through a melt-milling process, and their bioresorption and biomineralization behavior was evaluated by in vitro dissolution under different solution conditions (neutral and acidic). The particle size of S53P4 BG was controlled by milling, and the in vitro dissolution evaluation was performed in tris ...
Hace 3 días · Multiply the P2O5 percentage by 0.44. Example: A fertilizer with 30% P2O5 contains 13.2% elemental phosphorus (30% × 0.44 = 13.2%). To convert pounds of P2O5 per ton of fertilizer: Multiply the percentage of P2O5 by 20. Example: For a fertilizer with 20% P2O5, the calculation is 20% × 20 = 400 pounds of P2O5 per ton. 3.

Hace 3 días · A total of 63 metallurgical samples were collected from 37 sample locations along high-grade historic trench (TUTR10) at Tundulu. Sampling results returned up to a high of 3.35% TREO and 27.5% ...
Hace 2 días · Bioactive glasses, especially those based on borate, are characterized by their unique structural and mechanical properties, which are significantly influenced by boron content. Optimal boron levels enhance the thermal stability and bioactivity of these glasses, while excessive boron can degrade mechanical strength due to weaker -B-O-Si bonds. These materials are utilized in a range of ...
