Aspergillus niger reproduces asexually by forming conidia. Here, the minimal nutrient requirements were studied that activate germination of A. To this end, was monitored in time using an oCelloScope imager. Data used as input asymmetric model to describe process swelling and germ tube formation. The maximum number spores (Pmax) activated swell form tubes 32.54% 20.51%, respectively, medium wit...
Estimating balanced nutrient requirements for soybean (Glycine max [L.] Merr) in China is essential for identifying optimal fertilizer application regimes to increase soybean yield and nutrient use efficiency. We collected datasets from field experiments in major soybean planting regions of China between 2001 and 2015 to assess the relationship between soybean seed yield and nutrient uptake, an...
Herbivore physiological response to predation risk and implications for ecosystem nutrient dynamics.
The process of nutrient transfer through an ecosystem is an important determinant of production, food-chain length, and species diversity. The general view is that the rate and efficiency of nutrient transfer up the food chain is constrained by herbivore-specific capacity to secure N-rich compounds for survival and production. Using feeding trials with artificial food, we show, however, that ph...
Introduction Application of livestock manure provides nutrients for crop production and can also improve soil quality. However, the availability of nutrients in manure is difficult to predict. Therefore, livestock manure is frequently under or over-applied with respect to crop nitrogen and phosphorus requirements. In cases where the availability of nutrients is less than expected, application r...
