Improving P-efficiency in Crops Through the Management of Highly Effective Beneficial Soil Microorganisms

Better use efficiency of both indigenous soil phosphorus (P) and applied P fertilizer by cropping systems will extend the life of current mined world phosphorus deposits and reduce the need to develop lower grade phosphate rock deposits.

IPNI-2014-CAN-SK43

Potential benefits to the agriculture industry derived from the project Better use efficiency of both indigenous soil phosphorus (P) and applied P fertilizer by cropping systems will extend the life of current mined world phosphorus deposits and reduce the need to develop lower grade phosphate rock deposits. This will help make agricultural cropping systems more sustainable in the longer term. Read more

Interpretive Summary

Arbuscular mycorrhizal fungi (AMF) forms a symbiosis with 80% of plant species. In the context of the Prairie Provinces of western Canada, this includes most field crops except for canola and mustard. Plants benefit from association with AMF by enhanced phosphorus (P) absorption. Plants supply photosynthetically produced carbon substrate to AMF as a food source for the fungi.

Research indicates that the diversity of arbuscular mycorrhizal (AM) fungi in the Canadian Prairies has been negatively impacted by crop production practices such as the use of fallow and the prevalence of small grain cereals in rotation. The functionality provided by the original diversity of AM fungi to crop P nutrition has been reduced.
