Deer impact and plant resistance traits
… mass per area, Leaf dry matter content, C:N ratio, and Wood density) were tested and compared between low and high deer density area by using mixed effect statistical models. Leaf mass per area (LMA), leaf carbon-nitrogen ratio (C:N), and wood density did not respond significantly to …

Effects of certain fertilizer and lime treatments on some chemical properties of Cecil sandy loam
… of the pH, organic matter content, total nitrogen, and cation exchange properties of the soil of the l8-year-old rotation plots at Chatham, Virginia, was carried out. Individual soil samples were taken of each of the 36 sub-plots which compose the experiment. After the chemical analyses …

The Effect of Nitrates, pH, and Dissolved Inorganic Carbon Concentrations on the Extracellular Polysaccharide of Three Strains of Cyanobacteria Belonging to the Family Nostocaceae
… polysaccharides (EPS) in response to carbon and nitrogen availability as well as pH. While the carbohydrate compositions of the glycans produced by the different organisms were indicative of their recent evolutionary divergence, there were measurable differences that were dependent …

Development of a mathematical model for predicting bio-slurry temperature and subsequent gas production rate for underground brick-built biogas digester using ambient air temperature forecast
… on this type of digesters' actual field operation and performance within the SSA context is available. The end-user must know what needs to be done and what the system's outcome is supposed to be. Besides determining parameters like total solids, volatile solids, carbon-nitrogen ratio, …
