“…The pH values observed in the 10 to 20 cm layers are in agreement with those obtained by Barreto et al (2013), Duarte et al (2013), Dantas et al (2014) and Magalhães et al (2015), when studying the pH response on the application of increasing doses of cassava wastewater in different soils, observed a positive linear effect on the pH values. On the other hand, Cabral et al (2010) did not observe a significant difference of pH with the application of doses (0 to 600 m 3 ha -1 ) of cassava wastewater in the layers of 0.5 to 10 and 10 to 20 cm.…”

“…Similar results were observed by Homen et al (2014), for the calcium, when used wastewater from swine in Brachiaria decumbens cv Basilisk plants. Dantas et al (2014) also verified that the exchangeable calcium concentration in the soil decreased by approximately 22% with cassava wastewater in sunflower cultivation.…”

“…Homen et al (2014) also attributed this behavior to higher utilization of this nutrient by Brachiaria decumbens cv Basilisk. Dantas et al (2014), report the same reason for the reduction of exchangeable potassium concentration in sunflower plants and Magalhães et al (2015) in the corn crop.…”

There is a worldwide concern regarding the management of agroindustrial residues, involving sustainable practices that contribute to taking advantage of the residues as inputs in productive processes, allowing greater efficiency in the integration of agricultural activities and mitigating their adverse effects on the soil. Therefore, the objective of this study was to assess the effects of application of cassava wastewater on the chemical attributes of the soil cultivated with Brachiaria brizantha cv. Marandu. The experimental design was in randomized blocks with five treatments (0, 15, 30, 60 and 120 m³ ha-1 of cassava wastewater) and four repetitions. To characterize soil chemical attributes soil samples were collected at depths 0 to 10 and 10 to 20 cm, for determination of the concentrations of soil organic matter, available phosphorus, exchangeable potassium, sodium, calcium and magnesium before and after cassava wastewater application were determined. The application of cassava wastewater increases available phosphorus and exchangeable potassium concentrations, decreases exchangeable calcium, magnesium and organic matter contents of the soil cultivated with Marandu grass. Cassava wastewater can be used as organic fertilizer for pastures of Marandu grass with doses of up to 120 m³ ha-1.

The disposal and attendant problems associated with agro-wastes have remained a challenge to the environment. Three agricultural wastes (cassava whey, banana peels and groundnut shells) were collected from the Choba and Yam zone markets in Rivers State, Nigeria and screened for their potential as substrates in the formulation of fermentation media to produce oxalic acid. The inoculum for the study was isolated from the banana peels and identified using the megablast search for highly similar sequences from the NCBI non-redundant nucleotide database. The microbial load and proximate composition of the substrates were determined, and the fermentation media formulated. The organism used for the study was identified as Aspergillus niger MW188538. The results showed a total bacterial count of 9.5x104 cfu/ml, 1.87 x 105 cfu/ml, and 4.0 x 104 cfu/g for cassava whey, banana peels and groundnut shell respectively. The carbohydrates of the cassava whey, banana peels and groundnut shells were 67.74 %w/v, 53.24%w/v and 38.8% w/v respectively. After 12 days of fermentation, the substrates from cassava whey, banana peels, groundnut shells accumulated 2.5 ppm, 1.8 ppm and 1.3 ppm of oxalic acid respectively. The study hypothetically indicates that agro-wastes could be utilized as media components for production of industrial organics.

Conventional agricultural practices are very intensively utilizing synthetic agrochemicals. The resulting impact is a decrease in soil quality, thereby reducing fertilizer efficiency and plant yield. Efforts to maintain soil health include restoring organic matter. Organic fertilizers can be produced by utilizing the surrounding agricultural waste. Liquid organic fertilizer (LOF) can be produced from organic waste which should be chosen from high content of macro nutient. The quality of LOF could be increased by adding commercial decomposer starter or local microorganism. Organic matter of high energy should be added as well. The process of making liquid organic fertilizer is involved a fermentation process. Microbes will decompose organic material by breaking down the nutrients in the material to dissolve in solution. POC applications have been tested on various agricultural commodities. The provision of POC can increase the growth and yield of plants. In addition, the use of POC can improve soil health.
