- Abstract:
- ... Globally, the hillslope currently supporting sugarcane production is accelerating soil erosion and nutrient losses that degrade agroecosystem services and increase water pollution. However, sugarcane planting patterns (SPP), involving the arrangement of perennial (P) and newly planted (NP) sugarcane along hillslopes, may influence hillslope erosion and nutrient losses due to changes in root densit ...

Where diffuse losses of nutrients from agriculture is a major challenge for integrated catchment management and the achievement of Water Framework Directive objectives, modelling tools can be used to target the high-risk areas and focus the limited resources available for mitigation measures. The Catchment Characterisation Tool (CCT) is a GIS-based model developed to assess the potential risk pose ...

Inputs of this key nutrient contribute to increased yields, product quality and profits for farmers and ranchers across the globe. However, when higher rates of nitrogen (N) inputs than needed are applied to agricultural ...

It is, therefore, crucial to quantitatively assess nutrient inputs over time and their impact on riverine nutrient exports. In this study, we estimated the long-term (1995–2015) nutrient inputs at the county scale by integrating Net Anthropogenic Nitrogen Input (NANI) and Net Anthropogenic Pho ...

While soil mixing layer theory has been widely used to predict the solute loss, it has been observed that the conventional soil mixing layer models with constant mixing layer depth underestimate solute concentration in surface ru ...

In recent years, the release of the algal toxin microcystin has become a growing concern and has resulted in the inability to use water from Lake Erie as a drinking water source to the 400,000 residents of Toledo, Ohio in August, 2014. Farmers in the Western Lake Erie Basin have received the brunt of the bl ...

A paired-catchment study was conducted on a grazed dairy farm that tested the hypothesis that cultivating and sowing a low-P-requiring grass in near stream areas and high-P-requiring clover (Trifolium repens L.) elsewhere lost less P to water and was potentially more profitable than a mixed grass–clover pasture managed for the cover c ...

The Mississippi Delta has long been known for its fish productivity and recreational value, but high levels of P in fresh water can lead to algal blooms that have many detrimental effects on natural ecosystems. Algal blooms interfere with recreational and ...

Increasing the time between manure application and the first rain-runoff event is proposed as a practice to reduce runoff P loss. Few studies have investigated this aspect of manure P loss in runoff, with mixed results. Studies observing a decrease in r ...

- Abstract:
- ... Increasing nitrogen (N) and phosphorus (P) inputs have greatly contributed to the increasing food production in China during the last decades, but have also increased N and P losses to the environment. The pathways and magnitude of these losses are not well quantified. Here, we report on N and P use efficiencies and losses at a national scale in 2005, using the model NUFER (NUtrient flows in Food ...

- ... A new simulation model for N dynamics, DRAINMOD-N II, has been previously evaluated for only a few sites. We evaluated the model using ten years (1996-2005) of measured data from a subsurface-drained, corn-soybean agricultural system near Story City, Iowa. Nitrogen fertilizer was applied to plots at low, medium, and high rates (57 to 67 kg N ha -1 , 114 to 135 kg N ha -1 , and 172 to 202 kg N ha - ...

Given the state of the science concerning agricultural P transport, a simple tool to quantify annual, field-scale P loss is a realistic goal. We developed new methods to predict annual dissolved P loss in runoff from surface-applied manures and fertilizers and validated the methods wit ...

CNA is defined as the maximum allowable applied or generated amount (AGA) of a nutrient from natural and human sources that can be emitted and still allow compliance with water quality standards. The CNA calculation method is based on p ...

As a result, some Mid-Atlantic US states have developed P source coefficients (PSCs) to account for differences in P solubility between fertilizers, manures, and biosolids in P risk assessment tools. The reliability of these PSC ...

Wild shrubs may protect the soil against the erosivity of raindrops. However, some shrubs such as wild lavender are traditionally harvested by uprooting the entire plant. Thus, we studied here the impact of har ...

The high N inputs to agricultural systems in many regions in 27 member states of the European Union (EU-27) result in N leaching to groundwater and surface water and emissions of ammonia (NH₃), nitrous oxide (N₂O), nitric oxide (NO), and dinitrogen (N₂) to the atmosphere. Measures taken to decreasing these emissions often focus at one specific pollutant, but may have both antagonistic and synergis ...

The need to control glyphosate [N-(phosphonomethyl)glycine]-resistant weed biotypes with tillage and preemergence herbicides in glyphosate-resistant crops (GRCs) is causing a reduction in no-tillage hectarage thereby threatening the advances made in water quality over the past decade. Consequently, if environmental gains afforded by GRCs are to be maintained, then an in-field best management pract ...

However, there is evidence in the literature to suggest that alternate flood/drainage cycles can accelerate nutrient cycling and transport within the soil and, therefore, pose a threat to water quality through the process of ...
