We studied how different organic and inorganic nutrient inputs affect soil organic carbon (SOC) down to 70 cm in Kenya. After 19 years, all organic treatments increased SOC stocks as compared to the control, but mineral nitrogen had no significant effect. Manure was the organic treatment that significantly increased SOC the deepest as its effect could be observed down to 60 cm. Manure was the best strategy to limit SOC loss in croplands and maintain soil quality after deforestation.

We used the DayCent model to assess the potential impact of integrated soil fertility management (ISFM) on maize production, soil fertility, and greenhouse gas emission in Kenya. After adjustments, DayCent represented measured mean yields and soil carbon stock changes well and N2O emissions acceptably. Our results showed that soil fertility losses could be reduced but not completely eliminated with ISFM and that, while N2O emissions increased with ISFM, emissions per kilogram yield decreased.

In sub-Saharan Africa, long-term low-input maize cropping threatens soil fertility. We studied how different quality organic inputs combined with mineral N fertilizer could counteract this. Farmyard manure was the best input to counteract soil carbon loss; mineral N fertilizer had no effect on carbon. Yet, the rates needed to offset soil carbon losses are unrealistic for farmers (>10 t of dry matter per hectare and year). Additional agronomic measures may be needed.

We present a soil mid-infrared library with over 1800 samples from central Africa in order to facilitate soil analyses of this highly understudied yet critical area. Together with an existing continental library, we demonstrate a regional analysis and geographical extrapolation to predict total carbon and nitrogen. Our results show accurate predictions and highlight the value that the data contribute to existing libraries. Our library is openly available for public use and for expansion.

Yield-invigorating soils showed a higher content of organic matter and harbored unique bacterial communities with greater diversity than yield-debilitating soils. In addition, Chloroflexi was served as a keystone taxon in manipulating the interaction of bacterial communities. Our findings help elucidate the role of soil microbiome in maintaining crop production and factors controlling the assembly of soil microbiome.

This study focuses on the potential of catch crops as monocultures or mixtures to improve the soil water management and reduction of soil N leaching losses. All catch crop treatments preserved soil water for the main crop and their potential can be optimized by selecting suitable species and mixture compositions. Mixtures can compensate for the individual weaknesses of monocultures in N cycling by minimizing leaching losses and maximizing the N transfer to the main crop.

Unravelling relationships between plant rhizosheath, root exudation and soil C dynamic may bring interesting perspectives in breeding for sustainable agriculture. Using four pearl millet lines with contrasting rhizosheaths, we found that δ13C and F14C of root-adhering soil differed from those of bulk and control soil, indicating C exudation in the rhizosphere. This C exudation varied according to the genotype, and conceptual modelling performed with data showed a genotypic effect on the RPE.

Pineapple–banana rotation combined with bio-organic fertilizer application is effective in Fusarium wilt suppression. Bacterial and fungal communities are changed. Large changes in the fungal community and special Burkholderia functions in the network are likely the most responsible factors for soil-borne disease suppression. Pineapple–banana rotation combined with bio-organic fertilizer application has strong potential for the sustainable management of banana Fusarium wilt disease.

Since the 20th century, human beings have released a large amount of reactive nitrogen by excessive application of nitrogen fertilizer, which resulted in enhanced greenhouse effect. It is not clear how the ecosystem nitrogen cycle evolves during global warming. In this study, we collected global data and used meta-analysis to reveal the response of nitrogen cycle to climate warming. The results show that the future climate warming can accelerate the process of ecosystem nitrogen cycle.

The central Mongolian forest steppe underlies a recent decline of forested area. We analysed the site and soil properties in the Khangai Mountains to identify differences between disturbed forest areas with and without regrowth of trees. More silty soils were found under areas with tree regrowth and more sandy soils under areas without tree regrowth. Due to the continental, semi-arid climate, soil properties which increase the amount of available water are decisive for tree regrowth in Mongolia.

Nicknamed the
tree against hunger, enset (Ensete ventricosum) is an important multipurpose crop for the farming systems of the densely populated Gamo highlands in Ethiopia. Its high productivity and tolerance to droughts are major assets. Nevertheless, enset production is severely threatened by a wilting disease. This observational study aims to assess soil and leaf nutrients in enset gardens at different altitudes to see if fertility management can be linked to disease prevalence.

Long-term studies on the impact of land use change and crop selection on soil organic carbon (SOC) stocks in sub-Saharan Africa are scarce. Accordingly, this study analysed the impact of converting natural grasslands to a range of low-input production systems in a tropical savannah on SOC stocks. Apart from the cultivation of legume tree and/or shrub species, all land management techniques were detrimental. Grazed grasslands in particular had almost 50 % less SOC than natural grasslands.

Phosphorus (P) seems to be a limiting factor for forest nutrition. At many German forest sites, trees show a deficiency in P nutrition. However, total soil P is an inadequate predictor to explain this malnutrition. We examined if soil properties such as pH, SOC, and soil texture may be used to predict certain P pools in large forest soil inventories. Models using soil properties and P pools with different bioavailability are not yet adequate to explain the P nutrition status in tree foliage.

We investigated how the composition of bone char (BC) particles altered in soil and affected the soil P speciation by fractionation and X-ray absorption near-edge structure spectroscopy. Bone char particles (BC from pyrolysis of bone chips and BCplus, a BC enriched with S compounds) were collected at the end of incubation-leaching and ryegrass cultivation trials. Soil amendment with BCplus led to elevated P concentrations and maintained more soluble P species than BC even after ryegrass growth.

For this study we systematically investigated the molecular pattern of leaf waxes in litter and topsoils along a European transect to assess their potential for palaeoenvironmental reconstruction. Our results show that leaf wax patterns depend on the type of vegetation. The vegetation signal is not only found in the litter; it can also be preserved to some degree in the topsoil.

Investigation of a Dutch sandy profile demonstrated that buried soils provide beneficial growth conditions for plant roots in terms of nutrients. The intense exploitation of deep parts of the soil profile, including subsoil and soil parent material, by roots of the modern vegetation is often underestimated by traditional approaches. Potential consequences of deep rooting for terrestrial carbon stocks, located to a relevant part in buried soils, remain largely unknown and require further studies.

Switchgrass is a deep-rooted perennial grass bioenergy crop that can sequester soil C. Although switchgrass ecotypes vary in root biomass and architecture, little is known about their effect on soil microbial communities throughout the soil profile. By examining labeled root-C uptake in the microbial community, we found that ecotypes supported different microbial communities. The more fungal community associated with the upland ecotype could promote C sequestration by enhancing soil aggregation.

Different tree species affect interrill erosion, but a higher tree species richness does not mitigate soil losses in young subtropical forest stands. Different tree morphologies and tree traits (e.g. crown cover or tree height) have to be considered when assessing erosion in forest ecosystems. If a leaf litter cover is not present, the remaining soil surface cover by stones and biological soil crusts is the most important driver for soil erosion control.

This paper aims to test a new physically oriented approach to viticulture zoning at the farm scale which is strongly rooted in hydropedology and aims to achieve a better use of environmental features with respect to plant requirement and wine production. The physics of our approach are defined by the use of soil-plant-atmosphere simulation models which apply physically based equations to describe the soil hydrological processes and solve soil-plant water status.

In this study we show how soil water repellency (SWR) is linked to the quantity and quality of SWR markers in soils mainly derived from vegetation. To predict the SWR of topsoils, we find the strongest relationship with ester-bound alcohols, and for subsoils with root-derived ω-hydroxy fatty acids and α,ω-dicarboxylic acids. From this we conclude that, overall, roots influence SWR more strongly than leaves and subsequently SWR markers derived from roots predict SWR better.

Terroir chemical and biological footprinting and geospatial technologies are promising for the management of terroir units, particularly remote and proxy data in conjunction with spatial statistics. In practice, the managed zones will be updatable and the effects of viticultural and/or soil management practices might be easier to control. The prospect of facilitated terroir spatial monitoring makes it possible to address the issue of terroir sustainability.

The available soil water (ASW) is a major contributor to the viticulture "terroir". Electrical resistivity tomography (ERT) allows for measurements of soil water accurately and with low disturbance. This work reviews the use of ERT to spatialise soil water and ASW. A case example is also presented: differences in water uptake (as evaluated by fraction of transpirable soil water variations) depending on grapevine water status (as measured by leaf water potential) are evidenced and mapped.

Since seeds are the principle means by which plants move across the landscape, the final fate of seeds plays a fundamental role in the origin, maintenance, functioning and dynamics of plant communities. In arid and semiarid patchy ecosystems, where seeds are scattered into a heterogeneous environment and intense rainfalls occur, the transport of seeds by runoff to new sites represents an opportunity for seeds to reach more favourable sites for seed germination and seedling survival.

This study covers both aspects of understanding of soil system and soil contamination after 14 years of fertilizer application and residual effects of the fertilization 8 years after cessation of fertilizer treatment. Although many grassland fertilizer experiments have been performed worldwide, information about residual effects of fertilizer applications on grassland ecosystem functioning is still rare. This study reports the importance of monitoring of the long-term impact of fertilization.

Short summary
The "local adaptation" component of integrated soil fertility management operates at field and farm scale. At field scale, the application of implements other than improved germplasm, fertilizer, and organic inputs can enhance the agronomic efficiency (AE) of fertilizer. Examples include the application of lime, secondary and micronutrients, water harvesting, and soil tillage practices. At farm scale, targeting fertilizer within variable farms is shown to significantly affect AE of fertilizer.
