Impact of Snow on Soil Greenhouse Gases
Spring is finally in the air, and while the thermometers are slowly but steadily rising, we wanted to explore the impacts of the exceptionally snowy winter on the soil greenhouse gas emissions. For this post, we interviewed a researcher, Boris Tupek, who is based in Luke, the Natural Resources Institute Finland. Tupek’s research specializes in greenhouse gases, including measuring and ...

Toxicity and bioaccumulation of biosolids‐borne triclosan in food crops
Triclosan (TCS) is an antimicrobial compound commonly found in biosolids. Thus, plants grown in biosolids‐amended soil may be exposed to TCS. The authors evaluated the plant toxicity and accumulation potential of biosolids‐borne TCS in two vegetables (lettuce and radish) and a pasture grass (bahia grass). Vegetables were grown in growth chambers and grass in a greenhouse. Biosolids‐amended soil ...

IDHA chelates as a micronutrient source for green bean and tomato in fertigation and hydroponics
The new biodegradable chelating agent imidodisuccinic acid (IDHA) has been studied for its application in agriculture. This study was conducted to compare the efficiency of mixed IDHA and ethylene diamine tetraacetic acid (EDTA) formulations to provide Fe, Mn, Zn, and Cu to green bean (Phaseolus vulgaris ‘Perfección negra polo’) and tomato (Lycopersicum esculentum Mill. ‘Shiren’) plants grown in ...

Evaluation of elemental allelopathy in Acroptilon repens (L.) DC. (Russian Knapweed)
Abstract Although Acroptilon repens (L.) DC. (Russian knapweed) is known to concentrate zinc (Zn) in upper soil layers, the question of whether the elevated Zn has an allelopathic effect on restoration species has not been addressed. Experiments were conducted to investigate whether soils collected from within infestations of A. repens (high-Zn) inhibit the germination or growth and ...

Lettuce cationic nutrition and yield, and soil chemical characteristics as affected by vanadium application to leaves or soils
Lettuce plants (Lactuca sativa, L., cv. "trocadero") were grown in pots filled with an Alfisol Udalf or an Andisol Udand soil, under greenhouse conditions. Treatments consisted of adding vanadium to soils (0, 100, 250, 500 and 10001mg1kg1 or as foliar sprays (0, 10, 25, 50, and 1001mg111. Soil chemical characteristics, the cationic nutrition of lettuce and their yields were assessed. No ...
