The micronutrient and trace element status of crops grown on the Alberta soil quality benchmark sites

Description

Crop micronutrient concentrations of both vegetative tissues and grain, if applicable, were measured from 17 selected AESA soil quality benchmark sites in the fall of 2003. Micronutrients analyzed... More ≫

Description

Crop micronutrient concentrations of both vegetative tissues and grain, if applicable, were measured from 17 selected AESA soil quality benchmark sites in the fall of 2003. Micronutrients analyzed included boron, cadmium, chlorine, copper, iron, manganese, molybdenum, nickel, selenium, silicon and zinc. The purpose of this report is to provide an account of these micronutrient concentrations and to correlate them with a number of selected soil properties including soil pH, organic carbon, sand, silt and clay content, cation exchange capacity and calcium carbonate concentrations. In addition, the uptake, translocation and importance of each micronutrient are discussed, as is a summary of the effect of micronutrient partitioning between the grain and straw fraction, the effect of landscape form and the effect of provincial ecoregion on their concentration.

Description

Results of a field study conducted in the summer of 2000 showed that when the antioxidant ethylene diurea (EDU) was applied to crops, there were increases in several parameters. The next step was to verify whether the effects of EDU resulted from EDU-mediated protection against ozone or from plant growth promoting effects of EDU that are independent of ozone. A series of controlled environment trials were designed to test this hypothesis.

Description

Ozone is an important phytotoxic gaseous pollutant and is known or suspected to cause injury in crops, including yield reductions. Studies have been conducted using the antioxidant EDU (ethylene diurea) in programs aimed at the quantification of the effects of ozone on vegetation. For the present study, a protocol making use of EDU as an antioxidant was designed and implemented at a site near the city limits of Fort Saskatchewan, Alberta, an area having elevated ozone levels relative to other areas of the province.

Description

This report was commissioned to provide a review and interpretation of the scientific literature that describes the use and effects of chemical ozone protectants. The authors of this report were asked to determine if there was sufficient information available on these substances to warrant a field evaluation of their use. This was done as part of Alberta Environment's efforts to determine if ozone has the potential to cause negative (or positive) effects on plants in the province, with a focus on agricultural crops.
