Two fungal inoculants are commercially available in Canada and the USA that target improving plant access to soil phosphorus (P). Arbuscular mycorrhizal fungi and Penicillium bilaiae were used to inoculate wheat, lentil and flax grown in an organically-managed and a conventionally-managed soil. A second crop was grown after freezing the soil to evaluate if the inoculants carried over to a second crop. Crops in the organically managed soil were smaller and took up less P than the same crop in the conventionally managed soil. Inoculation with either inoculant improved shoot growth and P uptake in wheat grown in the organically-managed soil and in lentil grown in the conventionally-managed soil. Co-application of the inoculants was never superior to the single inoculants. Carry-over effects were slight and inconsistent.

评估两种商业真菌接种剂以改善土壤中种植的作物的磷供应，并具有不同的管理历史

两种真菌接种剂在加拿大和美国有售，旨在改善植物对土壤磷 (P) 的获取。丛枝菌根真菌和青霉用于接种生长在有机管理和常规管理土壤中的小麦、扁豆和亚麻。在冻结土壤后种植第二批作物，以评估接种剂是否会转移到第二批作物。与常规管理土壤中的相同作物相比，有机管理土壤中的作物更小，吸收的磷更少。在有机管理土壤中生长的小麦和在常规管理土壤中生长的小扁豆中，接种任何一种接种剂均可改善枝条生长和磷吸收。孕育剂的共同施用从未优于单一孕育剂。遗留效应轻微且不一致。
