Prior research has demonstrated that unique and salient objects in a visual display may capture an individual’s attention. However, researchers have shown that some individuals, such as those with video game experience, are better at resisting salient-driven capture compared to others (Chisholm et al., 2010). The first manuscript presented in...
Warming of the terrestrial biosphere due to the anthropogenic addition of carbon dioxide to the earth’s atmosphere is becoming a major focus of scientific inquiry. Predictions of the extent of this warming are hampered by uncertainty in the ability of the earth’s ecosystems to counteract this effect by sequestering carbon...
Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers.
Predicting plant available...

Legume cover crops can serve as important sources of nitrogen (N) in
Estimates of nitrogen (N) available from long-term application of organic
amendments are required to balance N inputs with crop N requirements. Two studies
were conducted to (1) determine N mineralized from organic amendments (manures
and composts) during year 2 after application, and (2) compare plant-available N
(PAN) determined via in...
Growing concerns over the rise of anthelmintic resistant populations of gastrointestinal nematodes (GINs) have led producers to look for alternative means of treatment. These sentiments have been echoed by organic producers, who are restricted from the use of synthetically derived anthelmintics in the US. Chicory has emerged as a potential...
The effect of incorporated sawdust, sawdust mulch and nitrogen (N) fertilizer rate on soil nutrients and other properties, N uptake, and plant growth in a young blueberry planting on a silt loam soil type was studied in 2004 and 2005. ‘Elliott’ highbush blueberry plants were established on raised beds that...
