Seaweeds for fertilization of agricultural crops

Anne-Kristin Løes, Senior Researcher, Norwegian Centre for Organic Agriculture (NORSØK), Norway

About the speaker: 

Anne-Kristin Løes is an expert in soil fertility and plant nutrition, with a high interest to study the effect of various wasted and recycled materials for fertilization. She is active in several projects to study how residues from marine materials such as captured fish (backbones etc.) and seaweed may be amended and applied to agricultural crops, including challenges such as a high content of salt and potentially toxic elements such as arsenic and cadmium.
