New paper out this week — glacial flour impacts crop yield and nutrition
Newly published research from Tingey et al. evaluates the impact of glacial flour treatments on the health, yield and nutritional value of soybean crops.
Published later this week in iScience, Sarah's paper describes a proof-of-concept study in which glacial rock flours from different regions were applied to soybeans as a growth supplement. The key findings are that:
- Glacial flour provides essential macro and micronutrients to soybean crops, enhancing bean yield.
- Glacial flour treatment also enhanced the biological functions of the plants themselves, as evidenced through measurement of nitrogen fixation rates and photosystem function.
- The geological context of the flour had significant impact on the nutritional suitability of the crops: beans treated with Icelandic glacial flours contained higher concentrations of various macro- and micronutrients compared with the control group; but beans treated with Himalayan flour were elevated in terms of some nutrients, but were also enriched in arsenic, which is a potential toxicity risk.
A more detailed article describing the work in the paper can be found on the iC3 website.
