“…Therefore, the number of bacteria was higher at the end of 50 days. This increase in the bacterial population was also verified by Mariano et al (2009). Clay soil presents a larger amount of organic matter, water retention capacity and a great number of microorganisms because of its colloidal characteristic, due to the presence of clay.…”

The stillage, which is a liquid residue from the distillation of the sugarcane ethanolic fermentation, contains organic matter and can be a big source of pollution when it is discarded in the wrong way. Its application as fertilizer has been extended, which is reason to cause concerns regarding the environment. The aim of this work was to evaluate and quantify the biodegradation of stillage in sandy and clay soils, besides verifying the efficiency of the Embiotic Line ® inoculum as an accelerator of the biodegradation. Bartha and Pramer respirometric technique was used to determine the production of CO 2 during the 50 days of the biodegradation process, and the quantification of the initial and final microorganisms was also conducted. Results were analyzed using the Friedman statistical test. Clay soils were significantly better on stillage decomposition when compared to sandy soils (p=0.0153). Clay soils presented greater efficiency in stillage biodegradation, with higher field capacity, better water, organic matter and microbial retention. Regarding the use of the embiotic line, the experiment has shown this product does not interfere positively in the stillage biodegradation for both soils, possibly needing adjustments in its composition.

“…Application of vinasse to the soils for sugarcane fertilization is known to reduce its deposition in waterways and its contaminant effects besides increasing sugarcane yields and reducing fertilizer expenses [5]. In many countries, vinasse is directly applied to sugarcane fields as a substitute for conventional potassium fertilizer products [6,7]. Nevertheless, composting of vinasse with filter cake reduces its deposition and contaminant effects through decomposition of raw organic matter in to soil building humus.…”

A study was conducted at Metahara Sugar Estate in Ethiopia with the objectives to determine the optimum rates of nitrogen and compost for sugarcane production, and the effect of compost on soil chemical properties. Four levels of nitrogen (0, 46, 92, and 138 Kg /ha) and five levels of compost (0, 5, 10, 15, and 20 ton/ha) were combined in factorial arrangement. The experiment was laid out in randomized complete block design with three replications. It was conducted on clay soils (Haplic Cambisols). Soil samples were taken before and after treatment application, and analyzed for pH (1:2.5), ECe, organic carbon, total N, available P, and available K. All the cultural practices were executed as per the estate's practice. Analysis of the soil indicated that except for pH value, all the salient soil properties including ECe, organic carbon, total nitrogen, available P, and available K were slightly increased due to compost application. Analysis of variance indicated that interaction effect between nitrogen and compost was significant (p<0.05) on stalk girth, stalk weight, cane yield, and sugar yield. Highest cane and sugar yields were obtained when 46 Kg N/ha applied with 15 ton of compost/ha. Net benefit to cost ratio was also found to be the highest, 1.12, for this combination. Therefore, 46 Kg N/ha with 15 ton of compost/ha is recommended for clay soils (Haplic Cambisols).

“…Vinasse produced at Metahara ethanol distillery is acidic in reaction, and contained 0.69 g/l nitrogen and 0.025 g/l phosphorus. In many countries, vinasse is applied to sugarcane fields as a substitute for conventional potassium fertilizer [1,3]. It is also a common practice to dispose vinasse on agricultural fields due to its technical simplicity and economic advantages [3].…”

“…Vinasse can modify temporarily some soil chemical characteristics such as pH, organic carbon, and exchangeable acidity [4]. However, in the long term, intensive application of vinasse is reported to increase soil salinity [3]. N, P and K are essential for healthy growth and development of sugarcane; K is required for synthesis of carbohydrate in the leaves and the subsequent translocation of sucrose to parenchyma of the stem.…”

A study was conducted at Metahara Sugar Estate in Ethiopia to assess effect of vinasse disposal on sugarcane fields. The experiment was laid out in a randomized complete block design with five replications. To simulate the amount of vinasse to be disposed, three levels of potassium chloride (0, 340, and 580 kg ha -1 ) were tested on three different soil types (brown clay loam, black non-vertic clay and black vertic clay). Soil analysis result showed that available K in the soil was ranged from 311-547 ppm. Potassium chloride application on cane fields had nonsignificant (P<0.05) effect for cane and sugar yields. Similarly, non-significant (p<0.05) effect was found for juice K2O and leaf nutrient contents (N, P and K%). Therefore, the level of potassium chloride applied at the proposed vinasse disposal rates didn't affect nutrient uptake, yield, and juice quality in the subsequent crop; thus at Metahara Sugar Plantation, sugarcane fields can be used as disposing site for vinasse. However, long-term effect of vinasse to sugarcane crop and dynamics of K in relation to availability and fixation in the soils of the plantation should be further investigated through vinasse application to sugarcane fields.
