“…This data gap regarding DT50 resulted in several applications of FPB on loamy agricultural fields (representing 38% of the topsoil in Denmark) in the Danish Pesticide Leaching Risk Assessment Programme (PLAP; Rosenbom et al 2015) combined with a fate study on FPB (Badawi et al, 2015). This confirmed the higher leaching potential and higher persistence of TFMP (DT50 N68 days at 15°C) in loamy soil than those given in EFSA (2012).…”

“…The study was carried out on one of the five fields included in the Danish Pesticide Leaching Assessment Programme (PLAP) (Lindhardt et al, 2001;Rosenbom et al, 2015) (http://pesticidvarsling.dk/om_os_ uk/uk-forside.html). The field covers 1.69 ha, has a surface slope of approximately 2.2% towards north-northeast (negligible surface runoff) and is located near Silstrup in the north-western part of Denmark on a loamy sub-glacial fractured low-permeable till (USDA classification: Alfic Argiudoil/Typic Hapludoll; USDA texture class: sandy clay loam/sandy loam) with a clay content of 18-26%, a silt content of 27%, a sand content of 8% and TOC in the plough layer of 2.2%.…”

Abstract. The application of nitrogen (N) fertilisers to crops grown on tile-drained fields is required to sustain most modern crop production, but it poses a risk to the aquatic environment since tile drains facilitate rapid transport pathways with no significant reduction in nitrate. To maintain the water quality of the aquatic environment and the provision of food from highly efficient agriculture in line with the EU's Water Framework Directive and Nitrates Directive, field-scale knowledge is essential for introducing water management actions on-field or off-field and producing an optimal differentiated N-regulation in future. This study strives to provide such knowledge by evaluating on 11 years of nitrate-N concentration measurements in drainage from three subsurfacedrained clayey till fields (1.3-2.3 ha) representing approximately 71 % of the surface sediments in Denmark dominated by clay. The fields differ in their inherent hydrogeological field settings (e.g. soil-type, geology, climate, drainage and groundwater table) and the agricultural management of the fields (e.g. crop type, type of N fertilisers and agricultural practices). The evaluation revealed three types of clayey till fields characterised by: (i) low net precipitation, high concentration of nitrate-N, and short-term low intensity drainage at air temperatures often below 5 • C; (ii) medium net precipitation, medium concentration of nitrate-N, and short-term medium-intensity drainage at air temperatures often above 5 • C; and (iii) high net precipitation, low concentration of nitrate-N and long-term high intensity drainage at air temperatures above 5 • C. For each type, on-field water management actions, such as the selection of crop types and introduction of catch crops, appeared relevant, whereas offfield actions only seemed relevant for the latter two field types given the temperature-dependent reduction potential of nitrate off-field. This initial well-documented field-scale knowledge from fields that are representative of large areas in Denmark is a first step towards establishing a differentiated N-regulation for clayey till areas. Additionally, it provides a unique starting point by identifying important parameters for future mapping of catchment-scale variations in nitrate concentrations and fluxes.

We evaluated the main leaching indices that have been used for decades for the protection of groundwater against contamination by pesticides. We describe the index classifications in detail and discuss their advantages and limitations relative to their prediction value. Most of the indices have similarities in the types of parameters they use. Some of the similarities are basic physicochemical properties of the pesticides such as their water solubility and their organic carbon partition coefficient, as well as characteristics such as environmental persistence in the soil and some soil characteristics. It is very difficult to maintain a simple index with high predictive power. However, comparisons are allowed by many indices among different active ingredients before pesticides are classified according to the risk of being groundwater contaminants. In contrast, limitations are the scarce inclusion of pesticide byproducts in the ground, lack of prediction capacity for polar pesticides, and lack of prediction of the vulnerability of groundwater to being contaminated by pesticides. Despite the limitations of such approaches, they are of great utility, particularly for protection of groundwater from pesticide contamination when little information is available, which is the case in most developing countries and in countries with economies in transition. Caution is recommended in the analysis of information generated by these approximations, which ideally should be validated experimentally in the different application scenarios and the needs for pesticide assessment based on local information.
