Channel Complexity

Restoration of riparian vegetation may reduce nutrient and sediment contamination of waterways while potentially enhancing stream channel complexity. Accordingly, the present study used a paired-site approach to investigate the effects of mature regrowth riparian vegetation on river channel morphology and soil nutrients (i.e. nitrogen and phosphorus), comparing four sites of degraded (pasture) and reforested reaches. A revised rapid assessment of riparian condition (RARC) was used to validate the site pairings. Riparian soil nutrient and elemental geochemistry were compared between paired sites, along with two parameters of channel width complexity and two for channel slope complexity. The RARC analysis confirmed the validity of the paired site design. The elemental geochemistry results indicated that underlying geology may affect the paired site analyses. Reaches with mature regrowth vegetation had greater channel width complexity but no difference in their riverbed slope complexity. In addition, degraded reaches had higher soil nutrient (i.e. nitrogen and phosphorus) concentrations, potentially indicative of the greater nutrient retention of pasture grass sites compared with mature regrowth forested reaches with less ground cover. Overall, the present study indicates that restoring mature regrowth riparian vegetation may increase river channel width complexity, although it may require canopy management to optimise the nutrient retention potential necessary to maximise the effect of riparian restoration strategies on freshwater environments.

Definition Of

<p>Ecosystems role in preserving water resources is acknowledged by EU Water Framework Directive 2000/60/EC and by Groundwater Directive 2006/118/EC. In this view nutrient concentration represent a critical aspect with regard to water quality and eutrophication. Nitrate pollution is specifically addressed by the Nitrate Directive 91/676/EEC, which provides nitrate management rules for farming activities, defines nitrate vulnerable zones and gives indications on nitrate monitoring in water bodies.</p><p>To preserve water quality levels an important role is played by Riparian Buffer Zones (RBZ) through the provision of the Ecosystem Service (ES) nutrient retention, the uptake process operated by plant roots. Research has shown how ES valuation is a very effective approach to support land management process, as it allows a better understanding of the importance of the role of ecosystems in guaranteeing wellbeing conditions for human communities and for the environment.</p><p>In order to perform a complete assessment of ES, the use of maps only providing information on processes occurring at/above the surface (e.g land use maps, or ecosystem maps, or ecosystem function maps) does not allow a complete analysis of underground dynamics.</p><p>In the case of the valuation of the ES “nutrient retention” provided by RBZ it is necessary to include the hydrogeological model and its links with the riverine network. The simple presence/absence of vegetation, or even a detailed vegetation classification map, cannot provide a complete description of all conditions required to fully assess this ES, as information on groundwater flow, sediments and soils characteristics is needed.</p><p>For the Riparian Vegetation Management Plan of the Gesso Stura Riverine Park a specific index to study vegetation contribution to nutrient retention was introduced: the VEgetation NUtrient-retention Service (VENUS) Index. This index provides land managers a semi-quantitative indication on the spatial distribution of “best conditions” (suitability map) for nutrient retention by vegetation; it is based on a simple set of parameters representing the main factors controlling the interactions between vegetation roots and water flows (runoff and groundwater) from surrounding areas towards water bodies.</p><p>The application of the VENUS Index improved the definition of management measures for riparian vegetation and allowed reaching the following results: (1) identification of homogeneous sectors in terms of RBZ relevance for nutrient retention; (2) assessment of different RBZ management scenarios with regard to nutrient retention performance; (3) definition of specific management measures to preserve and/or foster the provision of nutrient retention.</p>

Fact Sheet

Animal manures have been used as natural crop fertilizers for centuries. Because of poultry manure’s high nitrogen content, it has long been recognized as one of the most desirable manures. Besides fertilizing crops, manures also supply other essential plant nutrients and serve as a soil amendment by adding organic matter, which helps improve the soil’s moisture and nutrient retention. Organic matter persistence will vary with temperature, drainage, rainfall, and other environmental factors. This 2-page fact sheet was written by Michael A. Davis, D.R. Sloan, Gerald Kidder, and R.D. Jacobs, and published by the UF Department of Animal Science, November 2013. http://edis.ifas.ufl.edu/aa205

Practical Constraints

Long-standing fertilizer recommendations for field-grown nursery and landscape ornamentals are based on maximizing growth, not nutrient efficiency. Further, these recommendations fall short because of failure to consider 1) the extent of crop nutrient removal, 2) varying nutrient retention characteristics of soils across the United States, and 3) a body of research that suggests that woody ornamentals have a limited response to fertilization under most soil conditions. Concern for the environmental impact of fertilization justifies a reevaluation of current nursery fertilization practices, as well a discussion of the practical constraints on the adoption of new approaches, e.g., nutrient demand-driven fertilization. Research on the nutrient use patterns of woody plants will be reviewed with emphasis on implications for increasing fertilization efficiency. OSU research on water availability and nutrient-use interactions also will be presented.
