Filter cake in industrial quality and in the physiological and acid phosphatase activities in cane-plant

Abstract

Sugarcane filter cake, a phosphorus-rich (P) fertilizer, can affect not only P storage in sugarcane (Saccharum officinarum L.), but also its metabolism and photosynthesis. In this study, was evaluated the effect of different mineral fertilizers, with and without the use of filter cake, on P levels, gas exchange, acid phosphatase activity, sugar, hydrated alcohol production, and total soluble solids. Sugarcane (variety RB86 7515) was cultivated on dystrophic Typic Haplustox in a randomized complete block design. Three replicates were established in a 3 × 4 × 2 factorial scheme, with three P sources (Triple Superphosphate-TS, Natural Reactive Bayovar Phosphate-BP, and Natural Araxa Phosphate-AP), four rates of P as P 2 O 5 (0, 90, 180, and 360 kg ha −1), and the presence or absence of filter cake (7.5 Mg ha −1 , dry weight). The levels of foliar P (PCL) were determined, along with the accumulation of P in aerial plant parts (AAP), net CO 2 assimilation (A), stomatal conductance (g s), transpiration rate (E), acid phosphatase activity (APL), hydrated alcohol, total soluble solids (TSS), total recoverable sugar (TRS), and stalk production. The highest P rate with filter cake yielded the maximum concentration of P in leaves (1.7 g kg −1), leading to the highest P accumulation in aerial plant parts (17.8 kg ha −1), and furthering a sugar production of 197.1 kg t −1 , and stalk production (122.6 Mg ha −1). The highest rate of Triple Superphosphate alone or with filter cake yielded the lowest acid phosphatase activity, the highest rate increased the accumulation of P in aerial parts (18.8 kg ha −1), and for stalk production, produced 123.1 Mg ha −1 of stalks. The use of Triple Superphosphate associated with filter cake increased the production of sugar (192.5 kg t −1), hydrated alcohol (91.3 L t −1) and total soluble solids (18.4°Brix), while the use of higher P rates, regardless of the source, increased gaseous exchange in sugarcane plants.

Pertumbuhan dan Hasil Tebu (Saccharum officinarum L.) Keprasan Pertama pada Residual Kompos Blotong dan Residual Pupuk Anorganik

“…Hal ini memungkinkan bahwa hara yang diberikan melalui pemupukan dapat lebih baik diserap oleh tanaman sehingga PS 881 memiliki peningkatan konsentrasi hara fosfor sebesar 85.71% daripada varietas PS 862. Hal ini selaras dengan hasil penelitian pemberian kompos blotong pada tanah mampu meningkatkan ketersediaan hara (Vasconcelos et al, 2017) meningkatkan efektifitas serapan hara (Soltangheisi et al, 2019), serta menambah konsenterasi hara daun (Crusciol et al, 2021) untuk mendukung pertumbuhan tanaman tebu. Apabila didasarkan pada nilai batas kritis (N 1.8%, P 0.19%, dan K 0.9%) maka rata-rata kadar N (2.07%), P (0.30%), dan K (1.3%) dalam daun tebu tersebut sudah termasuk dalam kisaran yang cukup (Mccray et al, 2006).…”

Multivariate Behavior of Irrigated Sugarcane with Phosphate Fertilizer and Filter Cake Management: Nutritional State, Biometry, and Agroindustrial Performance

“…Data were extracted from Vasconcelos (2013) concerning the experiment conducted from June 2011 to June 2012 at the Fazenda Santo Antônio in the municipality of Itajobi, SP (21°11′S and 49°1′W, altitude of 469 m, climate Aw). According to Cepagri (2012), the Aw climate has rainy summers and dry winters.…”

“…One of the most strongly crops affected by these conditions is sugarcane, which is grown in large areas in the tropics and is totally influenced by the edaphoclimatic characteristics of the area. Phosphorus, as one of the nutrients that most contribute to high productivity and quality of sugarcane, when in inadequate levels in the plant, reduces biometrics and metabolic activities, while under adequate contents, there is increased development and final yield and improved clarification process of sugarcane juice (Rossetto et al 2010;Santos et al 2010;Vasconcelos et al 2017). The evaluation of different phosphorus sources and doses is a way to reduce soil nutrient losses, particularly in the tropics, and to guarantee increases in productivity and agroindustrial performance (Vasconcelos et al 2017).…”

“…In addition, there is a need to add sustainability to the production system, which can be achieved by using the filter cake: the result of the clarification and filtration phase of the sugarcane juice after going through the rotary filter, a largevolume organic compound rich in organic matter containing macronutrients in its composition, especially phosphorus. Filter cake improves plant nutrition and stalk and sugar productions, increasing the sugarcane agroindustrial performance (Santos et al 2010;Oliveira et al 2017;Vasconcelos et al 2017).…”

Utilization of Glycerol from Biodiesel Industry By-product into Several Higher Value Products

“…Filter cake is a good source of phosphorus. Phosphorus is important for supporting photosynthesis process and stomatal conductance, as well as promoting root growth (Vasconcelos et al 2017). The improved stomatal conductance is essential for increasing transpiration rates.…”
