Binational cooperation toward a goal of Smart Great Lakes
The Great Lakes are the world’s largest freshwater resource and a critical part of the Canada–USA interactions. In addition to their water resource advantage, they are critical to trade/transportation and recreation. The “Smart Lake Erie” concept is an information ecosystem supported by a robust sensor-driven network that will transform data into usable tools and create actionable information
Soil Incorporation of Silica-Rich Rice Husk Decreases Inorganic Arsenic in Rice Grain
Arsenic
decreases rice yield, and inorganic grain As threatens
human health; thus, strategies to decrease rice As are critically
needed. Increased plant-available silica (Si) can decrease rice As,
yet the source of Si matters. Rice husk, an underutilized and Si-rich
byproduct of rice production that contains less labile C and an order
of magnitude less As than rice straw, may be an economically viable
Si resource to decrease rice As, yet the impact of rice husk incorporation
on As in the rice–soil nexus has not been reported. This proof-of-concept
study shows that rice husk incorporation to soil (1% w/w) decreases
inorganic grain As by 25–50% without negatively affecting grain
Cd, yield, or dissolved CH<sub>4</sub> levels. Rice husk is a critical
yet perhaps overlooked resource to improve soil quality through enhanced
nutrient availability and attenuate human health risks through consumption
of As-laden grain
