| The retention of nutrients by 10-m-wide grass buffers and buffers under natural vegetation has been studied over 10 years in Jokioinen in southwestern Finland. The results have been compared with those from 70-m-long plots without buffers. Grass was sown on the adjacent field and plots without buffers in 2002, and the field plots and these were grazed for 12 and 24 days in summer 2003 and 2004, respectively. |

| Arable soil is a functional unit whose condition is vital to crop production, but also to ecosystems at large owing to the significant role of soil in global nutrient cycles and balances. The soil quality concept recognises the concern for the sustainability of current arable land use practices. It integrates soil chemical, physical and biological properties, and takes account of the interaction of soil with water and air. This paper reviews the soil quality concept and its applications and discusses the importance of the concept for the assessment of Finnish arable soils. Many aspects of the chemical quality of arable soil are already well known in Finland. In contrast, follow-up of the physical and biological soil components, which are increasingly seen... |

| In a three-year Research program of organic food and farming in Finland there are six projects under theme plant production and soil science. The projects focus on potato and red clover cultivation, waste composts and meat-bone meal as organic fertilizer and on-farm soil quality testing. Preliminary results are now available. |

| 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... |
