Soil fertility is one of the main constraints to agricultural intensification in Ethiopia. Like in many East African countries, nutrient depletion rates are exacerbated in Ethiopia by high erosion rates, biomass and animal manure removal from farm plots and limited application of mineral and organic fertilizers. In this paper, soil nutrient balances at plot level were calculated for 350 farms spread across the high potential highlands of Ethiopia. The nutrient input flows and output flows were monitored over a period of 3 years (2012–2014) using the monitoring for quality improvement toolbox. Average nitrogen (N), phosphorus (P) and potassium (K) balances were −23 ± 73, 9 ± 29 and −7 ± 64 kg ha−1, respectively. The situation was most severe for N, where average depletion rate was 0.2 % of the soil total N stock per year, which equals about 4.2 % of the available soil N pool. Depletion rates were highest in the relative intensive farming systems in mountainous areas located in the central and southern parts of Ethiopia. Nutrient depletion rates increased in time with 13, 3 and 10 kg ha−1 year−1, respectively for N, P and K during the monitoring period. The Ethiopian government responds to the on-going, and worsening, soil nutrient depletion by stimulating the use of mineral fertilizers. We conclude that the current efforts on increased inputs of mineral fertilizers are a step in the good direction, but to really halt and reverse soil fertility decline, organic fertilizer application and soil and water conservation should be an integral part of the intervention strategy.

Gewassen nemen voedingsstoffen (nutriënten) op uit de bodem. Door de gewassen elders te consumeren worden nutriënten verplaatst. Door urbanisatie en globalisering wordt deze disbalans in nutriënten versterkt. Als de nutriënten onttrekking niet gecompenseerd wordt leidt dit tot bodemuitputting en uiteindelijk tot degradatie van eens productieve gronden. Onttrekking van nutriënten kan gecompenseerd worden met organische en minerale (kunst)mest. Vooral in gebieden ten zuiden van de Sahara wordt dit vaak niet of onvoldoende gedaan, omdat kunstmest duur en risicovol is en er vaak onvoldoende organisch materiaal beschikbaar is.
An integrated approach to nutriënt availability and use efficiency

Brussels : European Sustainable Phosphorus Platform
Every year more than €3 thousand million is lost due to soil degradation. Soil fertility decline that comes with soil degradation limits food production and economic growth. To unlock the potential of soils, nutrients need to be used more efficiently. This holds in particular for P, because it has the lowest nutrient use efficiency of all nutrients required by crops. Although several pathways of change have been proposed already to increase the productive capacity of soils, new approaches are necessary to cope with the current trends of globalization, urbanization, growing resource scarcity and climate change. Such approaches should be based on Integrated Soil Fertility Management (ISFM), which combines the application of both mineral fertilisers and organic manures with other aspects of agronomic management (seed, crop protection, soil and water management).

Soils represent a major natural capital asset and have enormous potential to increase agricultural production while, at the same time, combating climate change and contributing to green economic growth. Yet, every year more than €3 thousand million is lost due to soil degradation. To unlock the potential of soils, nutrients need to be used more efficiently. This can be achieved by improving the recycling of nutrients, increasing organic matter content and applying fertilizers of the right type in the right amounts, at the right time and in the right place. There are several pathways of change that have been proposed to increase the productive capacity of soils. However, with current trends – globalization, urbanization, resource scarcity and climate change – new approaches are required. In our view, such approaches should be based on Integrated Soil Fertility Management (ISFM), which includes the application of both mineral fertilizers and organic manures. Subsequently, ISFM should be supplemented with site-specific interventions and a better match between supply and demand of (locally available) nutrients to make the best use of available resources, reduce environmental impacts and enhance green economic growth. The Fertile Grounds Initiative (FGI) was designed as an coordinated strategy of collaboration between actors in nutrient management at various spatial scales. It is based on eight subcomponents, which bring together the supply and demand of nutrients within a specific geographical area to make optimum use of site-specific interventions and available nutrients, supplemented with external imports. We expect the FGI to make a significant practical contribution to sustainable development in areas with limited soil fertility and nutrient availability, while at the same time resolving problems arising from nutrient excess in certain parts of the country and from (urban) waste streams, turning these into economic assets.

Buffer strips with no added fertilizers are a mitigation measure to reduce P loads from agricultural land to surface water. However, the experimental evidence on their effectiveness (BSE) has been from sloping locations with shallow flow and surface runoff. The aim of this experimental study was to quantify BSE for P on flat agricultural lowland, predominantly with deep flow. We selected sites characteristic of five major hydrogeological classes in the Netherlands and in each experimental field installed paired 5-m-wide unfertilized grass (BS) and reference treatments (REF) that abutted the ditch. The REF treatments were managed similar to the adjacent grass or maize field, but BS treatments were only harvested. Each treatment had a reservoir in the ditch to collect and measure discharge and flow-proportional P concentration for 3 or 4 yr. We also measured net P withdrawal, the P status of the soil and P concentration in upper groundwater. We found a significant BSE for P of 61% on the site with the shallowest flow and steepest slope (2%). At the other sites, BSE was low and statistically insignificant. We conclude that harvested unfertilized buffer strips reduce P loads from flat fields only in specific areas with high surface runoff and/or shallow flow, especially in combination with a high original soil P status

Het doel van dit rapport is om meer inzicht en kwantificering te krijgen van potentiële veranderingen in koolstofvoorraden in Nederlandse bodems. Gebaseerd op een nieuwe stratificatie van de Landelijke Steekproef Kartering (LSK) data zijn bodemkoolstofvoorraden voor de voornaamste landgebruikstypen en bodemtypen bepaald. Het resultaat voor de belangrijkste landgebruikveranderingen laat zien dat bodem C emissies elkaar veelal compenseren. Met het MITERRA-model is de potentie voor koolstofvastlegging berekend. Niet-kerende grondbewerking en verbeterde gewasrotaties hebben de grootste potentie voor koolstofvastlegging. De totale realistische koolstofvastlegging in de landbouw wordt geschat op maximaal 1 Mton CO2 per jaar. De voorgestelde verplichte maatregelen voor het vergroenen van de landbouwsubsidies kunnen zorgen voor additionele koolstofvastlegging. Daarnaast laat deze studie zien dat ook andere natuurtypen dan bos grote koolstofvoorraden kunnen vastleggen.

The EU thematic strategy for soil protection recognizes that soil degradation through erosion, soil organic matter decline, compaction, salinization and landslides occurs in specific areas, and that these areas must be identified in an unequivocal way. Currently, there are various risk assessment methodologies (RAMs) and the question has risen to what extent these RAMs yield similar outcome and, if not, whether the outcome can be harmonized, i.e. whether the results of the various RAMs can be made compatible or comparable. In this study i) the current status of RAMs for erosion, soil organic matter decline, compaction, and salinization in the European Union (EU27) is reviewed, and ii) the need and the options for harmonization are assessed. The need for harmonization was defined as the likelihood of achieving different outcomes when using different RAMs, whereas the options for harmonization refer to the efforts that are required to harmonize soil RAMs. The current status of RAMSs in EU-27 was assessed on the basis of questionnaires, which were sent out to soil specialists and policy officers in all Member States. We received more than 100 (response rate >50%) completed questionnaires. It turned out that many of the so called RAMs are still incomplete; they are ‘process (or threat) quantifications’ rather than methodologies that assess the risk of a soil threat. Moreover, there were significant differences between RAMs for a soil threat in terms of (i) the notion of the threat, (ii) data collection, (iii) data processing, (iv) data interpretation, and (v) risk perception. The need for harmonization appeared highest for erosion and salinization, whereas the options for harmonization were best for SOM decline. Harmonization of soil RAMs may be very complex and for that reason not always feasible. We suggest two options that may facilitate unequivocal identification of risk (or priority) areas for soil threats, i) a two Tiered approach based on data availability and spatial scale and ii) generic harmonization, i.e. combining standardization and harmonization in a rather pragmatic way

Unfertilized buffer strips (BS) are widely accepted to reduce nitrogen (N) loads from agricultural land to surface water. However, the relative reduction of N load or concentration (BS effectiveness, BSE), varies with management and local conditions, especially hydrogeology. We present novel experimental evidence on BSE for 5-m-wide grass BS on intensively drained and managed plain agricultural lowland with varying hydrogeology. We selected characteristic sites for five major hydrogeological classes of the Netherlands and installed paired 5-m-wide unfertilized grass (BS) and reference (REF) treatments along the ditch. The REF was managed like the adjacent field, and BS was only harvested. Treatments were equipped with reservoirs in the ditch to collect and measure discharge and flow proportional N concentration for 3 or 4 yr. In addition, N concentration in upper groundwater was measured. We found a statistically significant BSE of 10% on the peat site. At the other sites, BSE for N was low and statistically insignificant. Low BSE was explained by denitrification between adjacent field and ditch, as well as by the site-specific hydrologic factors including low proportion of shallow groundwater flow, downward seepage, low residence time in the BS, and surface runoff away from the ditch. We emphasize that a REF treatment is needed to evaluate BSE in agriculture and recommend reservoirs if drainage patterns are unknown. Introduction of a 5-m-wide BS is ineffective for mitigating N loads from lowland agriculture to surface waters. We expect more from BS specifically designed to abate surface runoff.

Unfertilized buffer strips (BS) generally improve surface water quality. High buffer strip effectiveness (BSE) has been reported for sloping shallow aquifers, but experimental data for plain landscapes with deeply permeable soils is lacking. We tested a novel method to determine BSE on a 20-m-deep, permeable sandy soil. Discharge from soil to ditch was temporarily collected in an in-stream reservoir to measure its quantity and quality, both for a BS and a reference (REF) treatment. Treatments were replicated once for the first, and three times for the next three leaching seasons. No significant BSE was obtained for nitrogen and phosphorus species in the reservoirs. Additionally, water samples were taken from the upper groundwater below the treatments. The effect of BS for nitrate was much bigger in upper groundwater than in the reservoirs that also collected groundwater from greater depths that were not influenced by the treatments. We conclude that measuring changes in upper groundwater to assess BSE is only valid under specific hydrogeological conditions. We propose an alternative experimental set-up for future research, including extra measurements before installing the BS and REF treatments to deal with spatial and temporal variability. The use of such data as covariates will increase the power of statistical tests by decreasing between-reservoir variability.

Observations on trends in soil organic carbon (SOC) in agricultural soils is an important basis for mandatory reporting of emission of greenhouse gases from land use. A decrease indicates that these soils are a source of CO2, an increase that they are a sink. IPCC Good Practice Guidance generally assumes that the SOC content of agricultural soils decreases. We evaluated large datasets on trends in SOC in the Netherlands and compared them with datasets from Belgium, England and with literature in general. Also, the soil organic matter simulation model Century was used for a better understanding of soil processes related to manure application and SOC dynamics. The IPCC assumption of decreasing SOC contents was not confirmed for Dutch agricultural soils: on soils with SOC <70 g/kg the SOC contents are constant or increase slightly. The large amounts of manure and fertilizers applied on agricultural soils in The Netherlands could explain this trend. The positive effect of manure on SOC from the calculation with Century is significant, but smaller than the calculated effect from using IPCC Guidelines for calculation of soil organic matter budgets in National Greenhouse Gas Inventories.
