Field-Scale Evaluation of Biosolids-Derived Organomineral Fertilisers Applied to Ryegrass (Lolium perenne L.) in England

Figure 2

Dry matter yield (DMY) of the grass crop as affected by the fertiliser treatment in 2009 (a) and 2010 (b). The 𝑥-axis shows the fertiliser type followed by the corresponding N application rate in kg per ha. Use 𝑛=4 (control) and 𝑛=3 (treatments) except when N=250 kg ha⁻¹, 𝑛=2.
