“…The world population has reached 7.6 billion people and is expected to reach 8.6 billion by 2030, 9.8 billion by 2050, and 11.2 billion by 2100 (Gerliani, Hammami & Aïder, 2019;Tripathi et al, 2019). To meet the global anticipated food demand caused by this population growth, various agricultural practices have been proposed and tested (Godfray et al, 2010), including the excessive application of chemical fertilizers, pesticides, and herbicides (Ju et al, 2007); large-scale utilization of water resources (Tilman et al, 2002); and intensive plowing (Koch & Stockfisch, 2006).…”

We used a constant total N application base rate to conduct a two-year field experiment comparing the effects of three organic fertilizers (rapeseed meal (RSM), soybean meal (SBM), and cattle manure (CM)) on the crop yield, economic growth, and soil quality of a winter wheat-summer maize rotation system. Winter wheat and summer maize in rapeseed meal treatment (RSMT), soybean meal treatment (SBMT), and cattle manure treatment (CMT) showed yield increases of 161%, 299%, and 256%, respectively, when compared to no organic fertilizer treatment (CK) (P < 0.05). The annual net incomes of SBMT and CMT were 1.46 and 1.42 times higher, respectively, than RSMT. Compared to the results of the CK group, RSM, SBM, and CM stimulated the soil physically, chemically, and biologically. We found the highest soil macroaggregate proportions, soil organic matter (SOM) levels, total N (TN) levels, and phospholipid fatty acid (PLFA) levels in SBMT. The highest soil pH, microbial biomass carbon (MBC) levels, and microbial biomass nitrogen (MBN) levels were observed in CMT. We used a soil quality index (SQI) to evaluate soil quality. After the two-year fertilization treatments, we calculated the SQI using a minimum data set (MDS). We used SOM levels and actinomycete quantity for the MDS properties. The SQI values were significantly different across the four treatments, with the highest values occurring in SBMT, then CMT and RSMT. In conclusion, SBM and CM were more effective than RSM at maintaining crop yield, economic growth, and soil quality.

“…Similarly, the highest amount of essential amino acids in catholytic soybean meal extracts was obtained by 300 mA—30 min with 126.6 mg/g, followed by 150 mA—10 min and 450 mA—50 min with respective amounts of 104.2 and 98.4 mg/g of protein. Samples extracted using electro‐activated solutions were compared based on their alkalinity to conventional ones prepared with NaOH from our previous work (Gerliani et al, ). Conventional extraction using alkaline NaCl 0.01 M (pH 8) and 0.025 M (pH 9), resulted in similar profiles of essential amino acids totalizing 147.7 and 131.1 mg/g of protein, while NaCl 0.05 M (pH 10) extracted the lowest amount of essential amino acids with 81.3 mg/g.…”

“…Thus, the electric‐activated solutions (anolyte and catholyte) can be used as a suitable replacement of chemical acid and basis for different purposes, including extraction procedures. Thus, electro‐activated solutions with given pH, acidity, and alkalinity can be selected to correspond with the alkalinity and acidity of conventional solutions that were used in previous work of Gerliani, Hammami and Aïder, () to carry out extraction from soybean meal (Gerliani et al, ).…”

“…In previous work of Gerliani et al (2019b), it was shown that the maximal molecular weight obtained in the basic conventional samples (pH 10 and alkalinity 0.07 mol/L) was 93.5 kDa which corresponds to molecular weight of lipoxygenase (Gerliani et al, 2019b). When electro-activated samples obtained under same alkalinity of 0.07 mol/L do not contain lipoxygenase, the maximal molecular weight for these samples was 67 kDa (which corresponds to molecular weight of alfa subunit of beta-conglycinin) in the sample 450 mA-50 min.…”

This main objective of this work was to study the extraction of proteins and soluble carbohydrates and minerals from soybean meal by using acidic (anolyte) and alkaline (catholyte) extracting solutions produced by electro‐activation technology. The extracting solutions (anolyte and catholyte) were produced by electro‐activation at current intensities of 150, 300, and 450 mA during 10, 30, and 50 min. Both extraction methods were effective in extracting soluble dry matter. The catholyte was the most efficient in extracting proteins with a maximal yield of 45.55 ± 2.77%. Moreover, protein content increased with treatment time in catholyte extracts but decreased in anolyte‐extracted samples. SDS‐PAGE confirmed catholyte effectiveness in extracting more proteins with better quality than the anolyte. Similar results were observed for amino acid profiles, with samples extracted by the catholyte being the richest in both essential and nonessential amino acids. While the anolyte extracted the highest amounts of Mg2+ (78%), Ca2+ (37%), and P3− (37%) from the soybean meal, catholyte was more efficient in extracting Zn2+ (65%), Fe2+ (62%), and Cu2+ (42%) ions. The obtained samples by both anolytes and catholytes exhibited good carbohydrate profiles containing some prebiotic monosaccharides. The carbohydrate profile varied with voltage used for the production of electro‐activated solutions and time. Stachyose and raffinose content increased with voltage used for anolytes production while decreasing in catholytes samples. Similarly, the highest stachyose and raffinose contents were observed for catholyte‐treated samples for 10 min, with respective ranges of 206.64–222.49 and 31.17–34.29 mg/g. To a lesser extent, anolyte‐treated samples for a longer time (30–50 min) were more efficient in extracting those sugars.
