“…The composting process did not substantially alter the chemical attributes of the manure (Table 2), corroborating Orrico Júnior et al (2010), which used the same composting method of the present study. However, due to the visual changes of the manure, we believe that the changes in the organic compounds were more qualitative than quantitative, which can be associated with the transformation of aliphatic molecules into aromatic (Merlin et al 2014).…”

Purpose Many studies evaluate the effect of successive applications of chicken manure on soil attributes. In Brazil, the commercialization of this waste is common, implying on its sporadic use instead of many applications at the same area. The short-term effects of a single application of chicken manure and the role of its composting on soil structural stability are not fully understood. This study investigated application of in natura (uncomposted) and composted chicken manure on the structural stability of a Rhodic Ferralsol after a short period following single application. Methods The experiment was performed in a Rhodic Ferralsol in Londrina, Paraná. Brazil. We applied in natura and composted chicken manure at doses of 4.5, 9.0, 13.5, and 18.0 Mg ha −1 plus a control without application. Soil samples were collected after 185 days at the 0.0-20.0 cm layer for laboratorial analysis. Results The composting of chicken manure did not affect soil structural stability. Chicken manure did not alter water-dispersible clay (x = 21.7%), but increased the mean weight diameter of water-stable aggregates (MWD = 5.43 + 0.068 × dose) through the agglomeration of aggregates with 0.5-4 mm into 8-19 mm. Conclusion Even after a short period of 185 days, the application of chicken manure increases the structural stability of Rhodic Ferralsols and its composting, in the way performed by many farmers, is not associated with the improvement of soil structural stability in short-term. However, other advantages arise from the composting of the manure and need to be considered prior its use.

“…The peaks at 470, 525, and 792 cm –1 (Si–O vibration) and 3699 cm –1 (O–H stretching) indicated the presence of quartz and kaolinite (Reig et al, 2002; Sivakumar et al, 2012; Saikia and Parthasarathy, 2010; Merlin et al, 2014; Müller et al, 2014). These peaks were present in OGr, OMr, and MMr and indicate the presence of soil minerals in the samples arising from translocation of the soil particles to the fertilizer nuclei.…”

The joint use of analytical techniques helps us to better understand the characteristics and chemical processes that may influence the efficiency of fertilizers. Differential scanning calorimetry, X‐ray diffractometry, and Fourier transform infrared spectroscopy techniques are helpful in capturing the differences in compounds and mineral presence in fertilizers before and after application to the soil. Organomineral and inorganic fertilizers have different capacities to make P available in the soil. Different methods of organomineral fertilizer production result in different capacities to provide P, so that the granulation process resulted in lower P solubility than the granule mixture. Understanding the behavior of different organomineral phosphate fertilizers will help the delivery of available P to plants. We evaluated differences in the characteristics and P availability of granulated organomineral fertilizer (OG), an organomineral granule mixture (OM), and an inorganic granule mixture (MM) and their residues (OGr, OMr, and MMr, respectively) after four 35‐d cropping cycles. Soil‐available P content, X‐ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and soluble P content analyses of the fertilizers and residues were performed. The OM soil had higher available P content after the crops than those with OG and MM. The OGr had the highest total P, water‐soluble P, and P soluble in neutral ammonium citrate and water and a more intense DSC peak related to the remaining monoammonium phosphate than OMr and MMr, indicating that OG had the highest capacity to provide P over time. The XRD and FTIR analyses showed the predominance of aluminum phosphates and the possible formation of low‐solubility compounds in all residues. Differential scanning calorimetry showed a change in the characteristics of the organic matter of OG and OM after application, indicating that these fertilizers have different solubilities and capacities to make P available. The granulation process of OG results in lower capacity to provide P than the granule mixture used for OM. The joint use of several analytical techniques helps clarify fertilizers' characteristics and the chemical processes that influence their efficiency and may be helpful for improving the management and manufacture of organomineral phosphate fertilizers.

“…The synthesis of bagasse into sodium lignosulfonate begins with the preparation of bagasse powder which will be isolated to separate the lignin from the bagasse. After lignin is formed, a Fourier transform infrared (FTIR) [32,33] test must be carried out to ensure the presence of lignin-forming components. The standard lignin used is commercial lignin from the lignin product of Aldrich and Kraft.…”

Bagasse is scientifically defined as waste from the extraction of sugarcane liquid after the grinding process. Bagasse is biomass which is used as raw material to be processed into surfactants. Bagasse fiber cannot be dissolved in water because it consists mostly of cellulose, pentosane and lignin. The optimum conditions for obtaining the highest yield and the best conversion of bagasse to lignin were achieved when used 80 mesh bagasse and 3 M NaOH as a hydrolysis agent. Then lignin is reacted with 0.25 sodium bisulfite to the surfactant sodium lignosulfonate. Lignin and sodium lignosulfonate were further characterized using a FTIR spectrophotometer to determine the components contained therein. The lignin component consists of phenolic functional group elements, aliphatic and aromatic groups, ketone groups, aren functional groups, amine groups and alkyl groups along with standard lignin components. Likewise with lignosulfonates, with indicator components consisting of C═C alkenes, Sulfate S═O, C═O carboxylic acids and S-OR esters. The NMR test was resulted the monomer structure of SLS surfactant bagasse. The results indicate that the lignin isolation process from bagasse has been successfully. Likewise, the sulfonation of lignin to lignosulfonate is also successful.
