A multivariate analysis of covariance to determine the effects of near-stream best management practices on nitrogen and phosphorus concentrations on a dairy farm in the New York Conservation Effects Assessment Project watershed

Abstract Harvest access systems (forest roads, skid trails, and landings) account for 90% of the erosion and sedimentation during harvesting activities. A well-planned harvest access system can reduce the surface area disturbed by logging, thereby decreasing the potential for erosion and sedimentation. Most Best Management Practices (BMP) guidelines suggest that the area disturbed by the harvest access system should range from 10 to 15%. We measured surface area disturbance by the harvest access system on 43 harvest sites on nonindustrial private forestlands in northern hardwood cover types in New York State and found that the average area percent disturbed was 6% with a range of 3 to 13%. The quality of BMP implementation was positively associated with the percentage of surface area disturbed, suggesting that harvests with a low percentage of surface area disturbance do not necessarily exhibit high-quality BMP.North.

Best Management

Nutrient loss from commercial vegetable fields has become a significant environmental issue in all the major vegetable-producing regions of the United States. Growers are facing potentially disruptive regulations aimed at improving the quality of both surface and ground water. Significant improvement in nutrient management will be required to meet this regulatory challenge. This paper discusses five practical, low-cost nutrient best management practices (BMPs). These BMPs are widely applicable, relatively inexpensive to implement, and can dramatically reduce nitrogen and phosphorus loss from vegetable fields. However, even with careful application of these BMPs, runoff and leachate from vegetable fields may periodically exceed environmental water quality standards, which are very stringent.

Water Treatments

Land application of recycled water is currently practised in many countries as an alternative to discharge directly into inland and coastal waters. In this field study, nitrogen (N) and phosphorus (P) availability in pasture plots that received recycled water was compared with that of plots which received single applications of superphosphate fertiliser (SSP). The treatments included recycled water applied continuously, recycled water applied alternately with fresh water, single application of SSP at the beginning of the experiment, and a non-amended control. Results from the study showed that the amount of N and P removed by pasture was significantly (P < 0.01) greater in plots that received both recycled water treatments than in the SSP-treated plot and the control. The amount of N (as nitrate and ammonium) leached below 1.0 m soil depth was significantly greater (P < 0.01) for the continuous recycled water treatment than the other treatments or the control. Nitrate was the dominant (>80%) form of N leached from all 4 treatments. In contrast to the findings for N, a greater proportion of applied P (47.9%) was leached below 1.0 m soil depth from the SSP-treated plots than from plots that received recycled water continuously (26.0%), alternately with fresh water (13.3%), and the control. Results from the study may be useful for developing best management practices for recycled water irrigation of pasture.

Abstract Forty-two forestry best management practices (BMPs) were assessed to determine the extent of voluntary application and their effectiveness in preventing water quality impacts in New York State. These BMPs were evaluated on 61 timber-harvested sites in the Catskill region (CR), and 53 timber harvested sites in the Adirondack region (AR) during the summers of 1997 and 1998. The overall application of suggested BMPs was 78% for haul roads, 87% for landings, 59% for skid trails, 88% for equipment maintenance/operation, and 73% for buffer strips. Departures were common for BMPs concerned with draining water off haul roads and skid trails, and for stream crossings; more attention must be devoted to those practices. Effectiveness of BMPs was apparent when they were applied. Nonparametric statistical tests showed a strong relationship between BMP application and prevention of sediment movement. Limiting sediment movement protects surface water. In the CR, 27 of the 33 BMPs tested showed a statistically significant (P < 0.10) relationship between BMP application and sediment movement. Similar results were observed in the AR; 26 of the BMPs tested were significantly associated with sediment movement. Imperfect application of BMPs reduced effectiveness. Road drainage structures, for example, generally failed to adequately control erosion when spacing between drainage structures was excessive. North. J. Appl. For. 17(4): 125–134.

In the catchment area of the Lake Patzcuaro in Central Mexico (933 km2) the apportionments of erosion, sediment, nutrients and pathogen coming from thirteen micro basins were estimated with the purpose of identifying critical areas in which best management practices need to be implemented in order to reduce their contribution to the lake pollution and eutrophication. The ArcView Generalized Watershed Loading Functions model (AV-GWLF) was applied to estimate the loads and sources of nutrients. The main results show that the total annual contribution of nitrogen from point sources were 491 tons and from diffuse pollution 2,065 tons, whereas phosphorus loads where 116 and 236 tons, respectively during a thirty year simulation period. Micro basins with predominant agricultural and animal farm land use (56% of the total area) accounts for a high percentage of nitrogen load 33% and phosphorus 52%. On the other hand, Patzcuaro and Quiroga micro basins which comprise approximately 10% of the total catchment area and are the most populated and visited towns by tourist 686,000 people every year, both contributes with 10.1% of the total nitrogen load and 3.2% of phosphorus. In terms of point sources of nitrogen and phosphorus the last towns contribute with 23.5% and 26.6% respectively. Under this situation the adoption of best management practices are an imperative task since the sedimentation and pollution in the lake has increased dramatically in the last twenty years.

Private Forestland

Abstract Protecting the quality of New York City’s 5,180 square-kilometer surface water storage and supply system is not achieved with extensive regulations or comprehensive filtration, but through voluntarism. With nearly 3,885 square-kilometers of forestland, the importance of fostering forest management that is compatible with water quality is paramount, yet challenging, given that approximately 90 percent of the system’s forestland is privately owned. The objective of this study was to evaluate voluntary best management practices implementation by nonindustrial private forestland owners in New York City’s water supply system. The theoretical constructs of the innovation-decision process model were tested for covariance using data collected from owners and their forestland in New York City’s water supply system. Path analysis indicated that certain types of knowledge predict an owner’s attitude formation or decision to use best management practices, but attitude formation does not always predict their decision. In addition, analysis of variance demonstrated that the implementation of best management practices does not always depend on a nonindustrial private forestland owner’s decision. This empirical result stimulates questions regarding the systemic variables at play in the transition from decision to implementation of forestry practices.
