The world population is expected to reach 9 billion by 2050 and such an increase will require raising global food production by more than 70%. When land is used intensively for agricultural production, soil fertility declines rapidly, since nutrients are extracted from the soil by crops. Historically, agro-chemicals have been used to mitigate this nutrient loss, and to maintain or increase annual crop yields. However, the increased use of agro-chemicals lead to serious environmental problems in addition to the economic losses. For instance, fertilizer budget account for $160 billion in global markets in 2011 and represented ~$3.4 billion annually in Canada, making it the 2nd leading expense of farm operation after feed. The rapid depletion of available phosphate (P) source is of alarming concern since at the present rate of consumption, these reserves will be depleted within 50-100 years. Among the future sustainable long-term scenarios to solve this urgent need, the development of new biofertilizers based on beneficial microorganisms is of paramount importance. The management of beneficial microorganisms in agriculture cannot only preserve soil health but can also ensures sustainable use of non-renewable resources like P, increase crop quality and yield as well as greatly reduce cost per hectare. This industry-driven project aims to create a "new microbial based-fertilizer formulation" that combines the beneficial effects of two of the most important plant growth promoting microorganisms (PGPM): the arbuscular mycorrhizal fungi (AMF) and their intimately associated phosphate solubilizing bacteria (PSB), along with sources of inorganic P from phosphate rock (PR). This new product meets an increased market demand and tendency of reduction of agro-chemical inputs reduction and employment of alternative strategies for increasing global food production.

到2050年，世界人口预计将达到90亿，这一增长将需要提高全球 粮食产量增长70%以上。当土地被密集地用于农业生产时， 由于农作物从土壤中提取养分，土壤中的养分迅速减少。从历史上看，农用化学品一直是 用于减轻这种养分流失，并保持或增加作物年产量。然而，增加使用 农用化学品的大量使用除了造成经济损失外，还导致严重的环境问题。比如说， 2011年全球市场的化肥预算为1600亿美元，2012年为34亿美元。 加拿大，使其成为仅次于饲料的第二大农场运营费用。可利用能源的迅速枯竭 磷酸盐（P）来源令人担忧，因为按照目前的消费速度，这些储量将 在50-100年内耗尽。在解决这一迫切需求的未来可持续长期方案中， 开发基于有益微生物的新型生物肥料是至关重要的。的 农业中有益微生物的管理不仅可以保持土壤健康， 可持续利用磷等不可再生资源，提高作物品质和产量，同时大大降低成本 每公顷。这个行业驱动的项目旨在创造一种“新的微生物肥料配方”， 结合了两种最重要的植物生长促进微生物（PGPM）的有益效果： 丛枝菌根真菌（AMF）及其密切相关的解磷细菌（PSB）， 沿着无机磷来源于磷酸盐岩（PR）。这种新产品满足日益增长的市场需求 减少农用化学品投入的需求和趋势减少和采用替代战略 增加全球粮食产量。
