Fundamentally, we have to move toward metrics that measure the performance of food production and environmental systems in a holistic manner, using indicators such as nutrients per drop of water, hectare of land or kilowatt of energy.
When the 100-fold concentrated nutrient solution was diluted by a factor of 20 200, the results showed that the standard deviations of the electrical conductivity (Ec) and the pH for four repeat measurements were 0 0.4 mS cm−1 and 0.057 0.12, respectively; therefore, the performance of the nutrient solution was stable.
The use of diluted acid can improve the performance of YH as nutrients but may decrease the molecular weight of product, thus resulting in losing the function of enhancement of enzymatic hydrolysis [ 17].
The negative effect of nutrient limitation on the performance of A. artemisiifolia and the interaction of nutrient availability with temperature explains why this species is confined to nutrient-rich disturbed habitats (Chauvel et al. 2006; Essl et al. 2009; Šikoparija et al. 2009).
From the long-term system operation, the most efficient energy-saving system with high performance of nutrient removal could be achieved with the aeration on/off mode of 30/90 min.
This study assessed the performance of constructed wetlands in terms of nutrient retention and associated parameters under the humid conditions of Ireland's temperate maritime climate.
This reaffirms the significance of the integrated use of vermicompost and inorganic fertilizers in enhancing the performance of tomato over the individual nutrient sources.
The performance of any bioreactor depends on nutrient supplied, biomass concentration, cell metabolites, aeration, pH and temperature control, heat removal for isothermal operation, shear rate, reaction rate, and product recovery.
CFD models the performance of the pond in removing nutrients, BOD, sedimentation, and pathogens.
During this 2-yr pilot project, the efficiency of relevant techniques and statistical design for the EULIT experiments in the mesocosms have been tested, as well as the performance of the mesocosms ahead of the nutrient manipulation.
