The bigger picture: GM contamination across the landscape
Ensuring the purity of conventional crops grown in the vicinity of genetically modified (GM) crops depends on understanding both short and long distance pollen flows. New research shows that current guidelines on the safe isolation distances for GM maize may not adequately prevent cross pollination of conventional crops. Contamination of conventional crops can occur where GM pollen ...

Sloppy seed-sorting main culprit in GM crop escapes
Careless handling of seeds may be the key reason for the unintended spread of genetically modified (GM) crops, a study has found. The discovery challenges the widespread belief that the main source of GM contamination is the transfer of pollen by bees from GM crops to non-GM counterparts in neighbouring fields. Human error during seed production and handling is the more likely culprit, say the ...

Where is your soil water? Crop yield has the answer
Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. Quantitative determination of the maximum amount of plant-available water in soil using traditional methods on soil samples remains challenging, especially at the scale of an entire field. However, a map of plant-available water capacity for a field would be instrumental in ...

Loss of wild pollinators would hit crops, finds study
The loss of wild pollinators from agricultural landscapes could threaten global crop yields, a study has found. Led by Lucas Garibaldi, an assistant professor at the National University of Río Negro inArgentina, a team of researchers compared fields containing many wild pollinators — mostly insects — with those containing few. They studied 41 crop systems across all continents ...

Cooler Weather Conditions, Late Planting, Impacts Insects on Crops
Rainy, cooler weather experienced recently throughout the region means slugs may be on the rise in some field crops, says an entomologist with the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. The rains combined with colder temperatures are ideal slug weather, said Kelley Tilmon, a field crop entomologist with Ohio State University Extension and the Ohio ...

Insect-eating bats save global maize farmers €0.91 billion a year from crop damage
Insect-eating bats are estimated to be worth US$ 1 billion (€0.91 billion) a year to maize farmers around the world, a new study has revealed. Not only do bats reduce crop damage by eating adult corn earworm crop pests, they also suppress fungal infections in maize ears. Bats and their habitats need to be better protected for their ecological and economic contributions, say the study’s ...

New mobile robot to support agri-tech experiments in the field
Scientists at the University of Lincoln, UK, have taken delivery of an advanced new mobile robot to support agri-tech experiments at the University’s agricultural field station. The Thorvald agricultural robot, developed with scientists from the Norwegian University of Life Sciences, is the latest piece of technology added to the facilities of the Lincoln Institute for Agri-food Technology ...

Some but not all plants can defend themselves against disease on saline soil
Some plants with resistance against a specific disease are also able to defend themselves effectively when they are stressed due to, for example, drought or saline soil. At the same time, the resistance of other plants no longer functions in these very same conditions. Although this had been assumed for some time, Wageningen scientist Christos Kissoudis is the first person to show why. As a ...

Kansas senator honored with soil stewardship award
A long-time champion for agriculture, research, and the United States’ soil resources, Senator Pat Roberts, a Kansas Republican, will be presented today (Mar. 18) with the 2013 Excellence in Soil Stewardship Award by the Soil Science Society of America (SSSA). The award recognizes policy makers whose exemplary leadership has strengthened the U.S. agricultural enterprise and the natural ...
