Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...

Micellar and Solubilization Properties of Biological Surfactant Surfactin

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.
