“…In the maize crop, the application of pyraclostrobin associated with soil nitrogen fertilization increases the nitrate reductase activity by, on average, 56% in relation to the control (Barbosa et al, 2011), and the nitrate reductase enzyme activity is the higher the closer to the application of nitrogen cover fertilization (Machado et al, 2013).…”

“…Furthermore, long-term field demonstrated reductions in soil stocks of C and N nutrients in the deep soil layers following the application of large quantities of synthetic mineral fertilizers, which was not observed under organomineral fertilizers [ 57 ]. Organomineral fertilizers also reduce nitrogen (NH 3 -N) volatilization compared to exclusive mineral fertilizers [ 58 ].…”

Sugarcane is one of the main alternative sources of biomass for the biofuel sector, and its large-scale production has considerable environmental impact. Organomineral fertilizers formulated with potential environmental contaminants, such as filter cake and sewage sludge, positively influence plant growth and development. The objective of the present study was to evaluate the chemical and physical characteristics of sugarcane fertilized with pelletized organomineral fertilizers based on filter cake or sewage sludge. Eight field treatments were applied, based on three organomineral fertilizer compositions (50%, 100%, and 150%) associated with two organic matter (OM) sources (filter cake or sewage sludge), in addition to a control with 100% mineral fertilizer application, and a no-fertilization control (0%). Sugarcane attributes were evaluated during two consecutive harvests. The weights of stalks per hectare (ton ha-1), sugarcane productivity (ton ha-1), quantity of sugar per hectare (TSH, ton ha-1), and physicochemical properties of sugarcane juice (pol [%], Brix [%], purity [%], and fiber [%]) were evaluated. There were no significant differences in the attributes between OM sources or organomineral fertilization treatments and the exclusive mineral fertilization. The organomineral fertilizer application rate recommended for maximum quantitative and qualitative sugarcane in the first sugarcane harvest was between 2 and 9% above the regular recommendation for mineral fertilizer, regardless of the OM source. In the second harvest, the sewage sludge source increased total sugar and sugarcane per hectare by 4.68 and 4.19%, respectively, compared to the sugarcane filter cake source. Sewage sludge and sugarcane filter cake are viable alternatives for organomineral composition and could improve economic returns and minimize negative environmental impacts in sugarcane cultivation systems.

“…Regarding the soil dynamics of C and N, long-term field report demonstrated reductions in soil stocks of these nutrients in deep soil layers after the applications of large quantities of synthetic mineral fertilizers, which did not occur when the fertilizer source was an organomineral [39]. Organomineral fertilizers also reduce nitrogen (N-NH 3 ) volatilization when compared to exclusively mineral sources [40].…”

Sugarcane is one of the major alternatives for the biofuel sector and its large production has considerable environmental impacts. Organomineral fertilizers formulated with environmental liabilities such as filter cake and sewage sludge positively affect parameters of plant growth and development. The objective of this study was to evaluate the chemical and technological characteristics of sugarcane fertilized with pelletized organomineral fertilizers based on filter cake and sewage sludge. Eight field treatments were studied, being three levels of organomineral (50, 100, 150%) of two organic matter sources (filter cake, sewage sludge), plus a control with 100% of the recommended fertilization via mineral fertilizer and no fertilization control (0%). Sugarcane was evaluated during two consecutive harvest, and the amount of stalks per hectare (ton ha−1), the sugarcane productivity (ton ha−1), the quantity of sugar per hectare (TSH, ton ha−1), and the chemical and technological analysis of the sugarcane juice: pol (%), brix (%), purity (%) and fiber (%) were evaluated. None of the organomineral sources or doses differed from the exclusive mineral fertilization. The analysis of both harvests indicated that the first cut was the most productive since the responses of the first harvest were superior or similar to the second harvest. The recommended organomineral dose to obtaining maximum quantitative and qualitative sugarcane results was between 102 and 109% of the regular recommendation for mineral fertilization, regardless of the organic source in the first sugarcane harvest. In the second sugarcane harvest, sewage sludge source increase by 4.68 and 4.19% the total amount of sugar per hectare and the quantity of sugarcane compared to the sugarcane filter cake source. Sewage sludge and sugarcane filter cake as sources for organominerals are viable alternatives and advantageous in economic and environmental terms for the cultivation of sugarcane.
