Abstract Lipids are important biomolecules in all biological systems and serve numerous essential cellular functions. The global analysis of complex lipids is very challenging due to the extreme diversity lipid structures. Variation linkages positions fatty acyl chain(s) on backbone, functional group modification, occurrence molecular species as isomers or isobars among some greatest challenges resolve lipidomics. In this work, we describe a routine analytical approach combining two liquid...

Abstract Phosphorus (P) is the second most important macronutrient that limits plant growth, development and productivity. Inorganic P fertilization in podzol soils predominantly bound with aluminum iron, thereby reducing its availability to crop plants. Dairy manure (DM) amendment agricultural can improve physiochemical properties, nutrient cycling through enhanced enzyme soil microbial activities leading improved bioavailability crops. We hypothesized DM will biochemical attributes...
