    Het ministerie van LNV wil duidelijk hebben of mestvergisting bij kan dragen aan de klimaatdoelstellingen waar de landbouw aan moet voldoen. De vraag is of mestvergisting kan bijdragen aan de reductie van broeikasgas- en ammoniakemissie, wat het (lange termijn) effect is op de organische stofopbouw en of het toevoegen van extra organisch materiaal aan de mest in de mestvergister hierop van invloed is. In deze studie is gekeken naar verschillende scenario’s: rundveedrijfmest, varkensdrijfmest, beide mest typen 100% vergist en beide mest typen met covergist met organisch materiaal. Uit de literatuur komt naar voren dat er nog weinig (veld)onderzoek gedaan is naar het verschil in effect dat mestvergisting heeft op de emissies en opbouw van organische stof in de bodem. Toedieningstechniek, (weers)omstandigheden, viscositeit van de mest en bodemcondities bepalen of mestvergisten wel of niet bijdraagt aan emissiereductie. Het wel of niet meteen afvoeren van de mest naar de vergister blijkt volgens het gebruikte vergistingsmodel het meest te bepalen of vergisting bijdraagt aan de reductie van broeikasgas- en ammoniakemissie. Monovergisting met rundveedrijfmest blijk volgens het organische stof model substantieel meer bij de dragen aan de organische stof opbouw in de bodem dan de overige meststypen.

    In het Klimaatakkoord is voor landbouwbodems een doelstelling van 0,5 Mton CO2-vastlegging per jaar in 2030 voorgesteld. Om dit te realiseren, is er behoefte aan een praktijktool die op perceel- en bedrijfsniveau veranderingen in bodem C-voorraad kan berekenen en het effect van bodem C- maatregelen kan kwantificeren. Uit een inventarisatie van mogelijke bodem C-modellen zijn er drie geselecteerd: CCB, NDICEA en RothC. De databehoefte van de modellen is in kaart gebracht en demodellen zijn getest aan de hand van twee langetermijndatasets, de ‘Mest als Kans’- proef en een langetermijnexperiment van proefboerderij Vredepeel. De keuze voor welk model te gebruiken als praktijktool hangt af van de beoogde toepassing. Wanneer de tool alleen voor monitoring van bodem C geschikt moet zijn, zou RothC een logische keuze zijn vanwege de minimale data-invoer en de mogelijkheid om makkelijk grote datasets (veel percelen) door te rekenen. Als het doel gericht is op advisering van boeren zou NDICEA geschikter zijn, omdat het meer indicatoren berekent en interacties met stikstof- (en fosfaat)bemesting meeneemt. CCB zit hier qua gebruikersgemak en databehoefte tussenin.

    Samenwerking tussen akkerbouw- en melkveebedrijven komt veel voor in Drenthe, met name in de vorm van grondruil. De provincie heeft Wageningen UR gevraagd om een expertbeoordeling voor de volgende vraag: is deze huidige vorm van samenwerking duurzaam en waar is nog winst te halen? Daarbij werd specifiek aandacht gevraagd voor organische stof, nutriëntenefficiëntie, bodemgezondheid en de inzet van gewasbeschermingsmiddelen. Uit de beoordeling blijkt dat de huidige vorm van samenwerking qua duurzaamheid niet of nauwelijks afwijkt van de situatie zonder samenwerking. Op de verschillende duurzaamheidsthema’s is nog wel winst te behalen. Het is daarvoor nodig dat de samenwerkende bedrijven gezamenlijk een teelt- en bodemplan maken.

    For the design of new, innovative mixed
    farming systems at regional level, a participatory
    method was used, followed by a case study approach in
    which we assessed four differentcroplivestock
    integration strategies in different biogeographical
    regions of Europe. One of these strategies was studied
    in Winterswijk, the Netherlands, and focused on land
    exchanges between dairy and arable farms,nature
    conservation on farmland and reduction of nitrate
    leaching. By cooperating together,livestock and crop
    farms could take advantage of specialisation within
    their own farm as well as beneficial exchanges (e.g.
    feed and manure) with other farms. Preliminary results
    showed that cooperating farms have often a more
    intensive farming system than noncooperating
    specialised farms. It is not yet clear whether
    cooperation helped farmers to intensify their system, or
    if cooperation is required to sustain already intensive
    systems.

Hanegraaf (2) (1) Land Dynamics Group, Wageningen University, PO Box 47, 6700 AA Wageningen, The Netherlands , (2) Nutrient Management Institute, Postbus 250, 6700 AG, Wageningen, The Netherlands Soil organic matter (SOM) is an essential natural resource in land-based agro-ecosystems and is said to be the most important indicator of soil quality. Quantification of the impacts of land use (change) on SOM contents and stocks is vital in understanding the present and future relationships with agronomic sustainability but needs to consider relevant drivers at the landscape scale. Routine agricultural soil analyses (RSA) are potentially an attractive source of information for SOM and Soil Organic Carbon (SOC) inventories because of the large number of analyses and large temporal coverage (decades). However, the use of RSA’s in this context has some drawbacks concerning for example sampling depth, sampling procedure and geo-referencing. In this study, SOM inventories based on routine soil agricultural soil analyses are investigated and validated using field surveys. This is done for a selection of Dutch agricultural landscapes. Analysis of land-use history of fields reveals that current SOM contents are strongly related to the temporal variability in land use. Grassland age and rotational schemes appear as key variables in understanding current SOM patterns. Furthermore data reveal that current SOM contents are related to the spatial variability in groundwater hydrology and soil texture. For the translation of these routinely determined SOM contents to soil organic carbon (SOC) stocks, pedotransfer functions (PTFs) are needed. Such PTFs can very well be based on significant non-linear relationships between gravimetric SOC contents and bulk density (R2=0•80). However, validating derived SOC stocks for the upper 10 cm using PTFs with a field survey reveals that SOC stocks based on RSA’s and PTFs are substantially lower. The observed differences are much higher than reported annual rates in SOC changes. SOC stock inventories that make use of RSA’s should be aware of the limitations involved.

    Distinct extractable organic matter (EOM) fractions have been used to assess the capacity of soils to supply nitrogen (N). However, substantial uncertainty exists on their role in the N cycle and their functional dependency on soil properties. We therefore examined the variation in mineralizable N and its relationship with EOM fractions, soil physical and chemical properties across 98 agricultural soils with contrasting inherent properties and management histories. Mineralizable N was determined by aerobic incubation at 20 °C and optimum moisture content for 20 weeks. We used multivariate statistical modelling to account for multi-collinearity, an issue generally overlooked in studies evaluating the predictive value of EOM fractions. Mineralization of N was primarily related to the size of OM pools and fractions present; they explained 78% of the variation in mineralizable N whereas other soil variables could explain maximally 8%. Both total and extractable OM expressed the same soil characteristic from a mineralization perspective; they were positively related to mineralizable N and explained a similar percentage of the variation in mineralizable N. Inclusion of mineralizable N in fertilizer recommendation systems should be based on at least one OM variable. The most appropriate EOM fraction can only be identified when the underlying mechanisms are known; regression techniques are not suitable for this purpose. Combination of single EOM fractions is not likely to improve the prediction of mineralizable N due to high multi-collinearity. Inclusion of texture-related soil variables or variables reflecting soil organic matter quality may be neglected due to their limited power to improve the prediction of mineralizable N.

    Biotic soil parameters have so far seldom played a role in practical soil assessment and management of grasslands. However, the ongoing reduction of external inputs in agriculture would imply an increasing reliance on ecosystem self-regulating processes. Since soil biota play an important role in these processes and in the provision of ecosystem services, biological soil parameters should be an integral part of soil assessment. The general objective of the current study is to investigate to what extent biotic soil parameters provide additional value in soil quality assessment of grassland on sandy soils. We measured abiotic and biotic soil parameters together with process parameters underlying ecosystem services in 20 permanent production grasslands. Cross-validated stepwise regression was used to identify abiotic and biotic soil parameters that explained the soil ecosystem services soil structure maintenance, water regulation, supply of nutrients, and grassland production, respectively. Process parameters underlying the ecosystem service soil structure maintenance such as bulk density and the percentage of sub-angular blocky elements were mainly influenced by SOM and its qualities. The correlations between penetration resistance at 0–10 cm and the percentage of soil crumbs with earthworms suggested a relationship to earthworm activity. Parameters underlying the service of water regulation showed no clear relationship to biotic soil parameters. Water infiltration rate in the field was explained by the penetration resistance at 10–20 cm. Process parameters underlying the service of nutrients’ supply such as the potentially mineralizable C and N were mainly determined by soil total N. The potential C and N mineralization were more related to biotic soil parameters, whereby each parameter was the other’s antithesis. The grassland production without N fertilization viz. the nitrogen supply capacity of the soil measured as N yield, was mainly explained by soil organic matter (SOM) and soil moisture, and to a lesser extent by soil total N. One gram of SOM per kg of dry soil corresponded to 3.21 kg N yield ha-1, on top of a constant of 15.4 kg N ha-1. The currently applied calculations in the Dutch grassland fertilization recommendation, underestimated in 85% of the production grasslands, the measured nitrogen supply capacity of the soil by on average 42 kg N ha-1 (31%). This legitimizes additional research to improve the currently applied recommendations for sandy soils. The response of N yield to N fertilization ranged from 35 to 102%. This wide range emphasizes the importance of a better recommendation base to target N fertilizer. The response of N yield to N fertilization was predicted by the total number of enchytraeids, the underlying mechanism of which needs further investigation on different soil types. This knowledge can be important for the optimal use of fertilizer and its consequences for environmental quality

    There is considerable concern in Europe that soil organic matter (SOM) contents are declining, which would threaten both agriculture and the environment. We performed a trend analysis of SOM contents in sandy soils, using historic data from routine agricultural soil analyses. Data were selected from grass, grass-maize rotation and maize fields in four adjacent provinces that had been sampled four to five times during the period 1984¿2004. Absolute (at least 1%) and relative changes (SOMt=20/SOMt=0) were calculated and regressed against initial SOM contents. Mean SOM content showed a north-south gradient per cropping system. We found no single uniform trend in SOM contents for any of the three systems. Over the 20-year period, SOM declined in c. 25% of all grasslands, amounting to 185 000 of the 635 000 hectares of land under grass and forage crops in the four provinces, and increased in a total of 267 000 hectares. Carbon accumulation in grassland sandy soils was calculated at 39 g C m¿2 year¿1 (top 5 cm). For the grasslands, initial SOM contents were linearly and negatively related to absolute changes in SOM; the relation with the relative change was best explained by using log-transformed values of SOM. We conclude that in grassland soils in the Netherlands, conservation of SOM requires identification of high-risk fields rather than high-risk areas. For continuous maize on sandy soils, the entire area may be denoted as high-risk, because all fields could reach the critical limit of 3.4% SOM in the near future
