“…Soil loss and the associated loss of nutrients and organic carbon (OC) can have serious on-site impacts, particularly for arable land, reducing soil productivity and threatening sustainable agricultural production. This is especially problematic in hilly landscapes (Pimentel 2006;Zuazo and Pleguezuelo 2008;Pimentel and Burgess 2013;Rickson et al 2015). The transfer of fine sediment from cropland to water bodies is considered to be the world's largest non-point pollution source and creates detrimental off-site effects (Vörösmarty et al 2010).…”

Methodological perspectives on the application of compound-specific stable isotope fingerprinting for sediment source apportionment

et al. 2017

Compound-specific stable isotope (CSSI) fingerprinting of sediment sources is a recently introduced tool to overcome some limitations of conventional approaches for sediment source apportionment. The technique uses the C-13 CSSI signature of plant-derived fatty acids (delta C-13-fatty acids) associated with soil minerals as a tracer. This paper provides methodological perspectives to advance the use of CSSI fingerprinting in combination with stable isotope mixing models (SIMMs) to apportion the relative contributions of different sediment sources (i.e. land uses) to sediments. CSSI fingerprinting allows quantitative estimation of the relative contribution of sediment sources within a catchment at a spatio-temporal resolution, taking into account the following approaches. First, application of CSSI fingerprinting techniques to complex catchments presents particular challenges and calls for well-designed sampling strategies and data handling. Hereby, it is essential to balance the effort required for representative sample collection and analyses against the need to accurately quantify the variability within the system. Second, robustness of the CSSI approach depends on the specificity and conservativeness of the delta C-13-FA fingerprint. Therefore, saturated long-chain (> 20 carbon atoms) FAs, which are biosynthesised exclusively by higher plants and are more stable than the more commonly used short-chain FAs, should be used. Third, given that FA concentrations can vary largely between sources, concentration-dependent SIMMs that are also able to incorporate delta C-13-FA variability should be standard operation procedures to correctly assess the contribution of sediment sources via SIMMs. This paper reflects on the use of delta C-13-FAs in erosion studies and provides recommendations for its application. We strongly advise the use of saturated long-chain (> 20 carbon atoms) FAs as tracers and concentration-dependent Bayesian SIMMs. We anticipate progress in CSSI sediment fingerprinting from two current developments: (i) development of hierarchical Bayesian SIMMs to better address catchment complexity and (ii) incorporation of dual isotope approaches (delta C-13- and delta H-2-FA) to improve estimates of sediment sources

“…Ine cient disposal of these bres can lead to eutrophication and other environmental challenges. Rickson et al (2015) submitted that such organic waste can improve soil fertility but the use of OPFF for this purpose is quite low as there are many alternative biodegradable and processed manures and fertilizers. As a result of this, these wastes are not properly utilized and are already constituting land ll problems in areas where palm oil is produced.…”

This study first evaluated the engineering properties of lateritic soil samples from three selected locations in South Eastern Nigeria (Nawfia, Okpuno, and Ugwuoba). The effect of Oil Palm Fruit Fibre (OPFF) on the properties of these soil materials was investigated, with special emphasis on road construction applicability. The samples were subjected to different tests to ascertain their index properties. Varying proportions of OPFF from 0.5% to 3% were incorporated into the soil samples and the effects were observed based on compaction and California Bearing Ratio (CBR) results. The control samples without inclusion of OPFF achieved the highest Maximum Dry Densities (MDD), the MDDs reduced linearly as the OPFF content increased. Consequently, the CBR values decreased with increase in OPFF. The reduction in MDD for the Nawfia samples ranged from 0.29% to 5.31% as the OPFF increased from 0.5% to 3%. The MDD of the Okpuno sample also reduced within the range of 1.25% to 9.51% whereas the reduction for the Ugwuoba soil is within the range of 1.55% and 9.79%. With the inclusion of the OPFF, there was up to 75% to 83% drop in CBR values of the soil rendering them very unsuitable for pavement subgrade. It was concluded that the presence of fibre depreciated the engineering properties of the earth materials. Direct application of OPFF in any part of road pavement has been dissuaded.

“…However, inefficient use of organic amendments can pose significant environmental challenges such as eutrophication of water bodies and leachate affecting groundwater. Applying these amendments to the soil in an optimum manner can result in an increase in soil organic matter, which improves soil fertility and minimises soil degradation (Rickson et al, 2015).…”

Sustainable land use has been identified as one way of tackling challenges related to climate change, population expansion, food crisis and environmental pollution. Disposal of oil palm fresh fruit bunch (FFB) solid wastes is becoming a challenge with an increased demand and production of palm oil. Whilst this poses a challenge, it could be turned into an opportunity by utilising it as a resource and fully valorise it to meet soil and crop demands. This review presents the potentials of FFB solid wastes, which include empty fruit bunch (EFB), mesocarp fibre (MF), palm kernel shell (PKS), as soil ameliorants. The major findings are the following: 1) pyrolysis, gasification, combustion, and composting are processes that can enhance the value of FFB solid wastes.
