White clover has a lower root biomass and a higher abundance of earthworms than grass. This might have an impact on the ecosystem services soil structure maintenance and water regulation when white clover is introduced in a grass-clover mixture. We investigated the root biomass, the abundance of earthworms and a selection of soil physical parameters in white clover, grass-clover, and grass with and without inorganic N fertilizer. The treatment with clover-only had a lower root biomass, a lower C/N-ratio of the roots, a higher abundance of earthworms, a higher number of earthworm burrows, a lower penetration resistance at the 20-30 cm soil layer and a lower proportion of crumbs in the soil, than the other treatments. This confirms the literature that pure... |

In this paper we present effects of four paired agricultural management practices (organic matter (OM) addition versus no organic matter input, no-tillage (NT) versus conventional tillage, crop rotation versus monoculture, and organic agriculture versus conventional agriculture) on five key soil quality indicators, i.e., soil organic matter (SOM) content, pH, aggregate stability, earthworms (numbers) and crop yield. We have considered organic matter addition, no-tillage, crop rotation and organic agriculture as “promising practices”; no organic matter input, conventional tillage, monoculture and conventional farming were taken as the respective references or “standard practice” (baseline). Relative effects were analysed through indicator response ratio... |

Soil quality is defined as the capacity of the soil to perform multiple functions, and can be assessed by measuring soil chemical, physical and biological parameters. Among soil parameters, labile organic carbon is considered to have a primary role in many soil functions related to productivity and environmental resilience. Our study aimed at assessing the suitability of different labile carbon fractions, namely dissolved organic carbon (DOC), hydrophilic DOC (Hy-DOC), permanganate oxidizable carbon (POXC, also referred to as Active Carbon), hot water extractable carbon (HWEC) and particulate organic matter carbon (POMC) as soil quality indicators in agricultural systems. To do so, we tested their sensitivity to two agricultural management factors (tillage... |

1. Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role. 2. To assess whether crop residue (leaf and root) traits determined SOC sequestration responses to OF, we coupled a global meta-analysis with field measurements across a European-wide network of sites. In the meta-analysis, we related crop species averages of leaf N, leaf-dry matter content, fine-root C and N, with SOC stocks and sequestration... |

It is frequently hypothesised that high soil fungal/bacterial ratios are indicative for more sustainable agricultural systems.Increased F/B ratios have been reported in extensively managed grasslands.To determine the shifts in fungal/bacterial biomass ratio as in fluenced by grassland management and to find relations with nitrogen leaching potential,we sampled a two-year-old field experiment at an organic experimental farm in the eastern part of The Netherlands.The effect of crop (grass and grass-clover),N application rate (0, 40, 80,120 kg N/ha 1 )and manure type (no manure,farm yard manure and slurry)on the F / B ratio within three growing seasons was tested, as well as relations with soil and crop characteristics,nitrate leaching and partial N balance.... |

Sampling and analysis or visual examination of soil to assess its status and use potential is widely practiced from plot to national scales. However, the choice of relevant soil attributes and interpretation of measurements are not straightforward, because of the complexity and site-specificity of soils, legacy effects of previous land use, and trade-offs between ecosystem services. Here we review soil quality and related concepts, in terms of definition, assessment approaches, and indicator selection and interpretation. We identify the most frequently used soil quality indicators under agricultural land use. We find that explicit evaluation of soil quality with respect to specific soil threats, soil functions and ecosystem services has rarely been... |

Reduction of tillage intensity by non-inversion and very superficial tillage techniques is expected to have effects on soil structure such as soil porosity and soil structure stratification. Our hypothesis was that, mainly due to earthworms’ activity, soil macroporosity increases in the superficial soil layer with non-inversion and very superficial tillage compared to ploughing whereas, the opposite would be observable in the deeper soil layers. In the framework of the FERTILCROP project (http://www.fertilcrop.net/fc-home-news.html), we compared the effects of ploughing, non-inversion tillage and very superficial tillage techniques on soil structure in soil strata and more specifically on soil macropores using non-destructive X-ray computed tomography (CT)... |
