Manipulation of stomatal density was investigated as a potential tool for enhancing drought tolerance or nutrient uptake. Drought tolerance and soil water retention were assessed using Arabidopsis epidermal patterning factor mutants manipulated to have increased or decreased stomatal density. Root nutrient uptake via mass flow was monitored under differing plant watering regimes using nitrogen-...

The objective of this paper was to review recent studies on nutrient synchrony and the effects of synchronization of energy and N supply in the rumen on nitrogen utilization and animal performance. Theoretically, synchronization of energy and N supply in the rumen should allow more efficient use of nutrients by rumen microbes, increase microbial protein and fermentation end products, and thus i...

The InVEST hydrologic models were designed to represent the dominant processes of sediment/nutrient delivery and retention by land use/ land cover (LULC). Since they are not standard rainfall-runoff models, classical calibration and testing methods are not always applicable. Testing and calibration were particularly difficult in our study region due to: i) the absence of local data (e.g. in-str...
