The impacts of peat on mycorrhizal traits has been studied in several field and greenhouse experiments at MTT Agrifood Research Finland In the field experiments, AMF traits were affected by cropping systems and preceding crops but also by peat amendment. Peat had a negative impact on mycorrhizal effectiveness and AMF spore numbers, but did not affect species frequency or the Shannon-Wiener diversity index. |

Worldwide interest in soil quality evaluation has increased rapidly throughout the past decade, prompting us to evaluate the long-term impact of four cropping systems on several biological, chemical and physical determinants of soil quality. We hypothesized that after 17 years several of the determinants would show significant differences between conventional cereal and low input/organic rotations. Four crop rotations were imposed on a silt soil from 1982 through 1999. Rotation A was a conventionally managed cereal rotation that received 100% of the recommended mineral fertilizer each year. Rotation B was also managed conventionally from 1982 until 1993, although it received only 50% of the recommended mineral fertilizer. From 1994 through 1999, rotation B... |
