New Rangeland Soil Research at a SYLVIS Fertilization Site

Friday, July 6, 2018

On June 25th, Emma Avery defended her master’s thesis in soil science on the long-term effects of biosolids on rangeland soil quality and plant community in the Central Interior of British Columbia. In 2016, Emma collected data on soil and vegetation growing at the OK Ranch in research plots that were established in 2002 by the Ministry of Forest and Range.

Her thesis primarily looked into which rangeland soil parameters were still influenced by biosolids applications 14 years after fertilization. Her findings indicate that rangeland restoration undertaken with biosolids has provided long-term increased soil water content, allows the soil to stay cooler during the day, has increased soil aggregate stability, and plants retain increased nutrient content. Ground cover and biomass production were improved as well when compared to non-restored rangeland soils. SYLVIS would like to congratulate Emma on her achievement and contribution to biosolids research, and especially the on-going development of the OK Ranch grasslands restoration story.
