Thinning techniques result in taster preferred wines, increased production costs

Four crop load management treatments were applied to 'Seyval Blanc' grapevines in a winery in upstate New York. Grapes from the treatments were made into wine and rated by a panel of tasters. The researchers' cost/return analysis recommended that crop load reduction techniques may only be economically justified if crop load is extremely high, and/or during poor growing seasons.

Study examines relationship between youth asthma rates and tree cover, vegetation in Texas

Scientists compared vegetation rates and asthma rates in metropolitan statistical areas (MSAs) of Texas to determine if childhood asthma rates were related to tree cover and vegetation. Asthma rates for each MSA were mapped and compared to vegetation maps using geographical mapping software. Results showed no statistically significant relationships between normalized difference vegetation index, canopy cover, and asthma.

Scientific review answers questions about use of best management practices

Scientists reviewed the national literature regarding management of urban landscape fertilization to protect water quality, focusing specifically on fertilization practices during plants' active summer growth period, the time of year when some municipalities and counties have enacted bans on fertilizer use. The reviewers found potential unintended consequences of increased nutrient losses from urban landscapes, particularly turfgrass, when recommended fertilization and irrigation practices are not followed. They recommend that further research be done to demonstrate any potential environmental benefits of fertilizer bans.

UK study supports benefits of gardening for older adults

Community Gardening Supports Stress Reduction, Healthy AgingA study explored the potential benefits of "allotment" (community) gardening for healthy aging, focusing on the opportunities for outdoor physical activity, social support, and contact with nature. Participants included 94 individuals aged between 50 and 88 years who were members of various indoor and outdoor activity groups. Allotment gardeners reported significantly less perceived stress than participants of indoor exercise classes.
