Slurry injection to optimize nutrient use efficiency in maize: Soil nitrogen dynamics and plant nutrient status
Slurry injection below maize seeds is a rather new application technique developed to improve the nitrogen use efficiency of liquid organic manure. To enable the characterization of the spatial and temporal soil mineral nitrogen (SMN) dynamics after slurry injection the present study aims to develop an appropriate soil sampling strategy. Three consecutive experiments were conducted. The first t...

متن کاملNutrient cycling in a simulated pond ecosystem.
Mathematical modeling of ecosystems requires a considerable amount of knowledge about the subsystems functioning within the broad framework and the various rate processes and transfer coefficients that control the dynamic aspects. A detailed analysis of the transfer rates and budget of inorganic carbon and nutrients in a simulated pond was conducted for assessment and comparison with aquatic bo...
متن کاملUncertainty propagation in an ecosystem nutrient budget.
New aspects and advancements in classical uncertainty propagation methods were used to develop a nutrient budget with associated uncertainty for a northern Gulf of Mexico coastal embayment. Uncertainty was calculated for budget terms by propagating the standard error and degrees of freedom. New aspects include the combined use of Monte Carlo simulations with classical error propagation methods,...
