Effects of Monoculture, Crop Rotation, and Soil Moisture Content on Selected Soil Physicochemical and Microbial Parameters in Wheat Fields
Figure 7
(a) Actinomycete, (b) protozoa, and (c) heterotrophic counts on a logarithmic scale displaying different reactions to monoculture and rotation in 2009. Monoculture = M -♦-; rotation = R --. Vertical bars denote standard deviation.
