“…The N, P, K and S levels in four different types of amended compost are given in Table 2. Trichoderma was used for every MSW compost treatment (T3 -T10) in order to accelerate composting process (AyanfeOluwa et al, 2017). T. viridi inoculum was added to the amended and unamended MSW compost at a rate of 1 litre broth (liquid media) per ton compost, the fungal count being 10 6 cfu mL -1 .…”

Article InfoComposting is a good option of solid waste recycling, but its use by the farmers is limited because of its low nutrient status. Our study has considered organic amendments to increase nutrient status of MSW compost. We prepared three types of amended compost by mixing 20% mustard oil cake (MOC) and 30% poultry manure (PM) or cowdung (CD) or sugarcane press mud (SPM) with 50% MSW compost. Trichoderma viridi inoculum was used to accelerate the composting process. Different amendments improved the nutrient level of MSW compost. A field experiment was conducted to measure the performances of amended MSW composts alone and with fertilizers on yield and nutrient content of brinjal (Solanum melongena) and soil fertility. The experiment was carried out at Bangladesh Agricultural University research farm having silt loam texture, 6.7 pH and 2.79% organic matter; the soil was Aeric Haplaquept under the order Inceptisols. There were 10 treatments consisting of chemical fertilizers (urea, TSP, MoP, gypsum & zinc sulphate) and four types of MSW compost (3 enriched and 1 unenriched). The nutrient status of soil had increased due to application of composts. Based on the results of fruit (edible portion) yield and N, P, K and S concentrations of brinjal, and soil nutrient availability, the mixture 50% fertilizers +10 t ha -1 of enriched compost (MSW + MOC + SPM in a ratio of 5:2:3) was found as the best treatment. Results of this study have significant value in fertilizer management strategies for brinjal cultivation in sub-tropical countries.

“…Compost is reputed for not only its ability to increase soil aggregate stability, porosity, carbon, and plant nutrients but reduces the pH and risk of erosion [133]. In an incubation study carried out by AyanfeOluwa et al [134], amending Ultisol and Alfisol with conventional and accelerated composts increased the pH, carbon, N, P, and K compared with a conventional practice (NPK fertilisation only). In a field study that was carried out to determine the benefits of the combined use compost and zeolite on the fertility of organic-rich Mediterranean soils, the available K concentration significantly increased compared with the control and zeolite only [135].…”

Co-Application of Charcoal and Wood Ash to Improve Potassium Availability in Tropical Mineral Acid Soils

et al. 2021

Potassium (K) is a macronutrient required by plants for energy production, enzyme activation, formation of cell wall, production of protein, and photosynthesis. However, K in the soil solution is leached from the rhizosphere before it interacts with soil colloids because of the abundance of kaolinite clay minerals in mineral acid soils such as Ultisols and Oxisols. These soils are highly weathered, low in organic matter, low in pH, but high aluminium (Al), and iron (Fe) ions. As a result, K becomes unavailable for plants, and this affects crop production and farmers’ profitability. This problem has steered the attention to the application of amendments to minimise K loss. Animal manures, plant residues, and composts applications are some of the corrective measures taken to improve the K availability in tropical acid soils. However, there is dearth of information on co-application of charcoal and wood ash as soil amendments to improve the K availability and the changes they cause to the dynamic equilibrium of K in mineral acid soils. Hence, this review discusses the dynamics, availability of K, and proposed mechanisms involved when charcoal and wood ash are used to amend tropical acid soils. The optimisation and understanding of the role of charcoal and wood ash co-application as soil amendments have potential benefits to improve the K availability and physicochemical properties of mineral acid soils.

“…Although, the composting acceleration technology is relatively new in Nigeria, AyanfeOluwa et al (2017) found that the compost mineralized properly comparable to the conventional compost in an incubation study. In a further work, AyanfeOluwa (2019) also reported that nutrients from accelerated compost are also available for maize production comparable to conventional compost and mineral fertilizer in a screen house study.…”

Accelerated compost (AC) biotechnology that reduces composting time to less than one month is gradually finding its way to farmers. This study therefore evaluated the fertilizer potential of a brand of commercial AC (OBD-plus) on a degraded Alfisol in Ibadan (derived savannah) and Ultisol in Ikenne (rain forest) of Nigeria, using maize as a test crop. The experiment was laid out in Randomized Complete Block Design with three replications. The treatments were AC at 0, 60, 90, 120, 150 and 180 kg N ha -1 , mineral fertilizer (NPK 15-15-15) and conventional compost (CC), each at 60 kgN/ha. Data collected on biomass yield, maize grain yield (MGY, t ha -1 ) and post-cropping soil chemical properties were subjected to ANOVA at α0.05. The average highest MGY from Ibadan (3.90) and Ikenne (3.86) were obtained from AC (180 kg N/ha), but these were not significantly different from other AC rates and NPK. The least MGY was obtained from control (2.1 and 2.0) which was significantly less than the CC (3.16 and 2.90). The AC improved the post-cropping soil pH, N and K. The mean MGY obtained from the six levels of AC in Ibadan; 3.44 and 3.98 t ha -1 in 2013 and 2014 were not significantly different from Ikenne (3.41 and 3.84 t ha -1 ). However, maize in Ibadan gave significantly higher biomass yield (19.40 t ha -1 ) than that of Ikenne (17.74 t ha-1) in 2013, with similar trend in 2014. Accelerated compost at 60 kg N ha -1 improved maize grain yield and post cropping soil properties in Ibadan and Ikenne, Nigeria as much as conventional compost. The performance of the accelerated compost was not location dependent in terms of MGY, but resulted in higher biomass production in the derived savannah ecology.
