Transgenic plants that are being developed for commercial cultivation must be tested under field conditions to monitor their effects on surrounding wildlife and conventional crops. Developers also use this opportunity to evaluate the performance of transgenic crops in a typical environment, although this is a matter of commercial necessity rather than regulatory compliance. Most countries have adapted existing regulations or developed new ones ...

It is common agronomic practice to perform a formal evaluation of the behaviour of new varieties under natural field conditions. Accordingly, shortly after the optimization of genetic engineering techniques on trees, a number of field trials were set up to assess GM trees modified for different genes. Here, we review the work that has been done in this arena in Europe over the last 25 years, and summarize what we learned from these experiments. ...

We tested if a single soil P capacity test allows for a reliable forecast of P leaching from agricultural soils with a high P load. In regions with intensively managed arable soils, the soil P content has been dramatically increased by verfertilization with significant P leaching losses as a result. As a consequence, in order to control the P losses, P fertilization has been legally restricted. In several EU28 countries, the ammonium lactate ...

In autumn 2009, a new three partnership project was started funded by the Agency for Innovation by Science and Technology (IWT – Flemish Government) in which an interactive and user friendly software will be developed to understand and improve the application of plant protection products in fruit orchards. The final goal of this project is to improve the distribution of plant protection products on the target, resulting in similar or better ...

Plant-based technologies including phytomining, phytoextraction, phytodegradation, phytostabilization and phytovolatilization have drawn much attention during the last decade. To examine the feasibility of these nature-based solutions to accumulate, degrade, stabilize or volatize metal(loid)s and/or organic contaminants, an increasing number of field studies have been conducted. This review critically evaluates influencing factors in phytomining ...

Gentle remediation options (GRO), i.e. in situ stabilisation, (aided) phytoextraction and (aided) phytostabilisation, were implemented at ten European sites contaminated with trace elements (TE) from various anthropogenic sources: mining, atmospheric fallout, landfill leachates, wood preservatives, dredged-sediments, and dumped wastes. To assess the performance of the GRO options, topsoil was collected from each field trial, potted, and ...

© 2018 International Society for Horticultural Science. All rights reserved. A series of multiyear trials, the longest of which continued for 12 consecutive years, describes the impact of fertilization or fertigation on total yield and fruit quality of ‘Conference’ pears. The trials focused on nitrogen (N) and potassium (K), the most important nutritional elements for this pear cultivar. The impact of climate conditions on the uptake of ...

A procedure to optimize the coverage and throughput for a DVB-H system is proposed. The performance of the system is evaluated by measurements for different modulation schemes, guard intervals, and MPE-FEC rates. Based on technical trial results, an optimal transmission scheme is proposed for a specific network, maximizing the coverage for a certain throughput requirement. This optimization will enable to select an optimal transmission scheme ...

We propose the establishment of a European Consortium for Open Field Experimentation (ECOFE) that will allow easy access of European plant and soil scientists to experimental field stations that cover all major climatological regions. Coordination and quality control of data extraction and management systems will greatly impact on our ability to cope with grand challenges such as climate change and food security.
