Application of Reflectance Near Infrared Spectroscopy for Animal Slurry Analyses

Abstract: The feasibility of using near infrared spectroscopy (NIRS) for rapid prediction of the composition of cattle and pig slurries was investigated. Samples with a total solids content from <1 to 15% were collected during a 3‐yr period and used for calibration and validation. Test samples were sealed in plastic bags and measured in a sample cell moved vertically during measurements. Reflectance data in the range 1200 to 2400 nm were used for calibration based on partial least square regression. Dry matter (DM), … Show more

“…However, Galassi et al (2010) did not observe a significant influence of supplementation of the diet with a mixture of 20% of wheat bran and 4% of sugar beet pulp on ammonia emissions and Triolo et al (2011) reported a high negative correlation (r=-0.952; p<0.001) between lignin content in the manure VS and its biochemical methane potential. Moreover, Bindelle et al (2009) demonstrated that the substitution of sugar beet pulp with a source of insoluble fibre, as oat hulls, decreased the synthesis of bacterial protein in the gut and the ratio faecal N:urinary N to levels similar or lower than those reached with the standard non sup- ally high which confirms the findings of other studies (Malley et al, 2002;Saeys et al, 2005;Ye et al, 2005;Sørensen et al, 2007) on the usefulness of this methodology to predict main chemical components of fresh slurry and the biochemical CH 4 potential in a range of organic substrates (Doublet et al, 2013;Triolo et al, 2014). The poor prediction for pH could be related to internal correlations to organic compounds giving no true correlations between pH and spectra absorbance peaks (Huang et al, 2007).…”

“…Feed samples (undried and ground 1 mm) were scanned using a standard 1/4 sample cell and the equipment in a vertical position. The samples were mixed thoroughly using a homogenizer RW14 (Ika-Werke, Staufen, Germany) during 1 min; then, 80 mL were transferred to handmade polyethylene bags (60 × 230 mm) to a level of 10 cm from the bottom, and the upper part of the plastic bags was sealed after removing air space (Sørensen et al, 2007). The slurry sample bags were scanned by using a large sample cell (200 mm length by 4.7 mm width, and 23 mm depth) with the equipment placed on its back and the sample cell in a horizontal position.…”

“…Near-infrared spectroscopy has been previously used as a technique to predict stability parameters in different organic wastes (Reeves and Van Kessel, 2000;Reeves, 2001;Malley et al, 2002Malley et al, , 2005Saeys et al, 2005;Shepherd et al, 2005;Huang et al, 2007;Sorensen et al, 2007;Fujiwara and Murakami, 2008;Albrecht et al, 2009;Vergnoux et al, 2009). To our knowledge, NIR spectroscopy has not been used to predict stability parameters for sewage sludge, and only few studies have reported using NIR spectroscopy to estimate microbial respiration in organic wastes.…”

“…Voorbeelden betreffen de studies naar nutriënten en zware metalen in dunne dierlijke mest (Sørensen et al, 2007;2015 parameters betreffen hier N en P, zware metalen en arseen. Hoewel in de dataset 6 compostmonsters waren opgenomen, was het onderhavige onderzoek niet gericht op de analyse van zware metalen en arseen in zuiveringsslib, compost en overige organische meststoffen.…”
