Field size as a determinant of common vole population density
Pest Management Science, EarlyView.Population densities of the common vole, an agricultural pest, increase nonlinearly with forage field size, especially in fields below 20 ha. Reducing the field size may help limit crop damage in farmland. Abstract BACKGROUND Environmental heterogeneity in agricultural landscapes is a key driver of biodiversity and ecological processes, yet its role in

Effect of annually repeated undersowing on cereal grain yields
Agricultural and Food Science, 2008 Cover crops can be used to reduce leaching and erosion, introduce variability into crop rotation and fix nitrogen (N) for use by the main crops. In Finland, undersowing is a suitable method for establishing cover crops in cereal cropping.

Environmental Toxicology, EarlyView.ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

RESEARCH ON TRIFOLIUM PRATENSE L. FERTILITY IN RELATION WITH THE CROP SYSTEM
Agricultura, 2012 The importance of red clover as forage crop and in rotations for soil improvement is well known, but a great attention is being paid in various countries, to the study of those factors which influence the seed-set of this plant.

Red clover increases micronutrient concentrations in red clover
, 2014 Foraeg crops provide micronutrients as well as energy, protein and fibre to ruminants. However, the micronutrient concentrations of forage plant species differ, legumes generally having higher concentrations than grasses. In addition to that there are also strong effects of soil type.
