The study integrated perennial forage phases (1−5 years) into annual wheat systems. In the publication it indicates that once a treatment was converted from a perennial to spring wheat it was no longer fertilized. However, we have discovered that each time wheat was planted a starter fertilizer of 11−52−0 (NH₄; P₂O₅) was applied at 56 kg ha^–1 equating to 6.2 kg N ha^–1 and 29 kg P ha^–1. In addition, during seeding of legume and legume/grass mixture treatments, 11 kg P ha^–1 [monocalcium phosphate, Ca(H₂PO₄)₂] was applied.

勘误表：多年生草料影响一年生小麦种植系统中的矿物质和蛋白质浓度

该研究将多年生草料阶段（1-5 年）整合到一年生小麦系统中。在该出版物中，它指出一旦处理从多年生小麦转变为春小麦，就不再施肥。然而，我们发现每次种植小麦时，施肥量为 11−52−0（NH ₄ ; P ₂ O ₅），施肥量为 56 kg ha ^–1  ，相当于 6.2 kg N ha ^–1 和 29 kg P ha ^–1。此外，在播种豆类和豆类/草混合物处理期间，施用了 11 kg P ha ^-1  [磷酸一钙，Ca(H ₂ PO ₄ ) ₂ ]。
