From: Compost and humic acid amendments are a practicable solution to rehabilitate weak arid soil for higher winter field pea production

Figure 1

Compost and humic acid incorporation in arid soil improved the productivity of field peas by modulating soil microbial densities and biomasses. (a) Microbial C biomass (µg g−1 soil), (b) Microbial N biomass (µg g−1 soil), (c) Microbial P biomass (µg g−1 soil), (d) Microbial biomass C:N, (e) Microbial biomass C:P. The Tukey's HSD test results at p < 0.05. At the top of the vertical bars, distinct letters revealed apparent variances in treatment mean values. The standard deviation is displayed in the error bars (n = 3).
