“…The addition of black liquor (pH 10) resulted in rapid increases in soil pH by 0.1 to 0.5 units within 2 d and then stabilized throughout the remaining 58 d of incubation (data not shown). This result is in agreement with other studies that found an increased soil pH with alkaline paper mill effluent irrigation for 15 yr (Kannan and Oblisami, 1990a), or soils amended with alkaline mill sludge for 1 yr (Beyer et al, 1997). Increases in soil pH by black liquor indicate that black liquor has potential as a fluid liming material.…”

Sodium-based black liquor from fiber pulping for papermaking creates challenging waste disposal issues. By substituting NaOH with KOH in the pulping process, the resulting black liquors may be land applied as an environmentally beneficial disposal alternative. Incubation studies examined the effect of KOH-based black liquor on soil pH, electrical conductivity (EC), microbial biomass, CO 2 evolution, and soil enzyme activities in a silt loam soil. Amended soils with black liquor at rates up to 67.2 mL kg 21 soil, corresponding to 1200 kg K ha 21 were incubated at 24°C for 60 d. Increasing application rates increased soil pH, indicating that black liquor has potential as a fluid liming material. Soil EC increased with black liquor application rates, but only up to 1.04 dS m 21 , suggesting that black liquor application at these rates would not cause a salinity problem. Carbon dioxide evolution rate peaked at 2 d of incubation, and then gradually declined until the end of incubation. Metabolic quotient significantly increased with increasing application rates. Soil microbial biomass, CO 2 evolution, dehydrogenase, b-glucosidase, and arylsulfatase activities generally increased with increasing application rates throughout the incubation period. In contrast, increasing soil pH with KOH alone generally decreased CO 2 evolution and soil dehydrogenase, b-glucosidase, and arylsulfatase activities, indicating that this liquor effects in increasing soil microbial activity were possibly attributable to organic constituents contained in this liquor rather than its high pH.

“…This indicated that 524 toxicity has been reduced significantly after bacterial degra-525 dation. The growth promoting effects of untreated effluent on 526 amylase at lower concentration might be due to the presence 527 of optimum level of organic nutrients essential for plant growth 528 (Kannan and Oblisami, 1990). The reduction in amylase activity 529 at higher concentration of undegraded effluent might be due to 530 the high pollution content affecting various physiological and 531 biochemical processes during the seed germination.…”

“…The lowering of the observed pH can be explained by a direct effect of the biolignin acidity on the soil since it is extracted by an acidic process, that is to say, formic acid and acetic acid as confirmed by Kannan and Oblisami [10] and Veeresh et al [56].…”

“…However, the application of large quantities of boiler ash also adds significant amounts of trace metals and other elements that may be harmful to plants and the environment in general. Nevertheless, the application of black liquor, as studied by Kannan and Oblisami [10,11] and Xiao et al [12], revealed an increase in organic carbon content with an improvement in the enzymatic activities in the soil.…”

The Valorization of Biolignin from Esparto Grass (Stipa tenacissima L.) Produced by Green Process CIMV (Compagnie Industrielle de la Matière Végétale) for Fertilization of Algerian Degraded Soil: Impact on the Physicochemical and Biological Properties

This study proposes a new use for a paper industry waste material, lignin, in agriculture and agronomy as a fertilizer for arid soils, while following a strategy aiming to both increase the amount of organic matter in these soils and decrease the impact of pollution caused by industrial discharges that contain organic and/or inorganic pollutants generated by the paper industry. In fact, this method works to improve soil quality through a new carbon-rich bioorganic fertilizer (biolignin) that results from a green method called CIMV, a targeted depollution objective of the paper industry. Over the course of 180 days, we monitored the physicochemical and biological characteristics of degraded soils treated with three different biolignin treatments of 0 (D0), 2 (D1), and 4 (D2) g/kg. The humification was then evaluated by the equation E4/E6. A remarkable variation of the physicochemical and biological parameters was observed in D1 and D2: temperature 12–38 °C, humidity 9–29%, and pH 7.06–8.73. The C/N ratio decreased from 266 to 49. After 180 days, the improvement in soil carbon content for the three treatments D0, D1, and D2 was 14%, 19%, and 24%, respectively. A maximum bacterial biomass of 152 (CFU/g soil) was observed on the 30th day for D1. Maximum laccase activity for D2 was observed on the 120th day. D1 and D2 recorded a significant degree of humification compared to D0. The best indicator of humification E4/E6 was observed in D1, where the value reached 2.66 at the end of the treatment period. The D2 treatment showed a remarkable effect improving the fertility of the degraded soil, which confirms that biolignin is a good fertilizer.
