“…Examples include biochar (alone or in composted mixtures), livestock manures, woody residues (sugarcane bagasse, food processing biproducts), and minerals [19][20][21]. Mixtures that include both organic and mineral materials, such as lake-dredged materials [22,23], or a combination of the previous mineral-organic materials, have also been explored. The primary problems in their re-use, in comparison with CSS, as fertilizers in infertile soils include: (i) higher market cost (zeolite, struvite, clay minerals); (ii) poor market availability and environmental accessibility (lake-dredged materials); (iii) requiring complex and expensive technologies for amendment/fertilizer formulation (biochar, biochar-composted mixtures, struvite); (iv) restrictions imposed on their re-use (fly ash, slag, lake-dredged materials, livestock manure, food processing biproducts); and (v) low effectiveness when used alone (limestone, wood residues) [20][21][22][23].…”

Naturally infertile soils require large amounts of mineral fertilizers to obtain the desired crop yield. In the Cerrado region of Brazil, there is a need to investigate the potential of organic fertilizers to sustainably increase crop productivity and food security. A field study was conducted over two experimental seasons to evaluate the agronomic effectiveness of composted sewage sludge (CSS) as a fertilizer for soybean cultivation in infertile tropical soils. A 4 × 2 + 2 factorial randomized complete block design was applied with the following treatments: (i) CSS: 5.0, 7.5, 10.0, and 12.5 Mg ha−1 on a wet basis applied according to two different methods: whole area (WA) or between rows (BR); (ii) comparison with two alternative treatments: a control with no CSS and mineral fertilizer application, and an area treated with conventional fertilizers only. All the treatments were compared in terms of micronutrient concentrations in surface soil and plant leaves, plant development, crop productivity, and yield. Bi- (ANOVA, correlation matrix, and polynomial regression analysis) and multivariate (PCA, principal factor analysis) statistics were applied to determine statistical differences and relationships/observed variability among the treatments. Results showed that at higher CSS-WA rates: (i) soil and leaf micronutrient concentrations increased; (ii) there was an increase in soybean yield by 12 and 20%, respectively, as compared to control and conventional fertilization; (iii) soybean yield was 67% higher than the mean soybean yields for Brazil. Research outcomes confirm the benefits of CSS application on infertile agricultural soils in the Cerrado region, representing a strong alternative source of micronutrients in the CSS with respect to conventional fertilizers.

“…Freshwater bodies of Northern Guinea Savanna Zone of Nigeria is one of the largest water bodies rich in aquatic fauna. The sedimentation of the water bodies is rich in macronutrient due to the anthropogenic activities around the areas (Capra et al 2015). Sediment are component of the aquatic ecosystem found at the bottom of water reservoirs, rivers, streams and lakes which accumulates organic particles and mineral parts of various sizes.…”

“…Dushyantha et al, (2017) proposed that the lake sediment could possibly be used as a low-grade phosphate fertilizer for direct applications in low intensity farming. Furthermore, Capra et al, (2015) suggested the use of sediment for fertilization. Sediment texture is the measure of the number of particles (clay, sand and silt) found in the sediment component (Melquiades et al, 2014).…”

Sediments from freshwater bodies of the Northern Guinea Savanna Zone of Nigeria act as reservoirs for mineral and chemical nutrients washed from different sources around the environment. This research aimed at assessing the chemical and macronutrients of the sediments from freshwater bodies and the geomorphology of the area. A global positioning system, Model N9 GARMIN eTrexLegend™, personal navigator® was used to determine the geomorphological features while a polyvinyl chloride tube of 1.0 m long, 25 mm in diameter and 2.0 mm thick was used for sediment collection from a depth of 0-15 cm. The result of the chemical properties of the sediment; pH, organic carbon, organic matter and total nitrogen were found to be higher in dry season whereas phosphorus was high in the rainy season and there was no variation in the macronutrient across the dry and rainy season. Sand had the highest percentage across both seasons for particle distribution. This study revealed that sediments are rich in macronutrients and can be employed for agricultural purposes.

“…Sediment reuse has been proposed as a practice contributing to the circular economy concept, considering sediment as a resource rather than waste (Brils et al 2014), and many studies emphasize its positive effects (e.g., Fonseca et al 1998;Sigua 2009;Junakova and Balintova 2012;Mattei et al 2017;Braga et al 2019). Capra et al (2015) reported on the reuse of dredged sediment for the replacement of soil degraded by erosion, concluding that the addition of sediment had beneficial effects on the physicochemical properties of the soil and resulted in higher total dry matter production in plants. Also, Sigua et al (2004) observed increases in biomass production when they reused dredged sediment, and Braga et al (2017) found that the addition of sediment in sunflower cultivation improved the relative chlorophyll content and total dry mass when compared to plants growing on substrate containing commercial fertilizers.…”

Reservoir sediment characterisation by diffuse reflectance spectroscopy in a semiarid region to support sediment reuse for soil fertilization

et al. 2022

Purpose Soil erosion by water yields sediment to surface reservoirs, reducing their storage capacities, changing their geometry, and degrading water quality. Sediment reuse, i.e., fertilization of agricultural soils with the nutrient-enriched sediment from reservoirs, has been proposed as a recovery strategy. However, the sediment needs to meet certain criteria. In this study, we characterize sediments from the densely dammed semiarid Northeast Brazil by VNIR-SWIR spectroscopy and assess the effect of spectral resolution and spatial scale on the accuracy of N, P, K, C, electrical conductivity, and clay prediction models. Methods Sediment was collected in 10 empty reservoirs, and physical and chemical laboratory analyses as well as spectral measurements were performed. The spectra, initially measured at 1 nm spectral resolution, were resampled to 5 and 10 nm, and samples were analysed for both high and low spectral resolution at three spatial scales, namely (1) reservoir, (2) catchment, and (3) regional scale. Results Partial least square regressions performed from good to very good in the prediction of clay and electrical conductivity from reservoir (< 40 km2) to regional (82,500 km2) scales. Models for C and N performed satisfactorily at the reservoir scale, but degraded to unsatisfactory at the other scales. Models for P and K were more unstable and performed from unsatisfactorily to satisfactorily at all scales. Coarsening spectral resolution by up to 10 nm only slightly degrades the models’ performance, indicating the potential of characterizing sediment from spectral data captured at lower resolutions, such as by hyperspectral satellite sensors. Conclusion By reducing the costly and time-consuming laboratory analyses, the method helps to promote the sediment reuse as a practice of soil and water conservation.
