“…The basal soil respiration (BSR) and substrate induced respiration (SIR) of the soils were measured according to Alef (1995) content with T5 treatment for both soils support the positive effect of organic matter amendment (Table 3). The finding was similar with the other studies (Santri et al, 2019;Ademba et al, 2014;Bekele et al, 2018;Zhang et al, 2019;Gudeta and Damtew, 2019;Chiezey and Odunze, 2009) where the application of lime in lower rates along with different organic composts successfully neutralized the soil pH of different acid soils.…”

Aim: To evaluate the efficacy of integrated application of lime at partial doses of lime requirement (LR) with vermicompost in acid soils to minimize the soil acidity, improve the population of beneficial microorganisms and their microbial activities in comparison to sole treatment of lime as per Lime Requirement dose. Methodology: Two highly acidic soils collected from the farmer’s field of South 24 Parganas district, West Bengal having no history of acidity management were used. The soils were treated with different rates of lime requirement (LR, ⅔LR & ½LR) and lime (½LR) + vermicompost (5 tha-1) treatments and incubated for 60 days. Soil pH, soil organic carbon content, different microbial populations, microbial respiration and enzymatic activities (FDHA and DHA) were assessed at different days. Results: The study indicated that the lime treatments showed rapid increase in soil pH towards the slightly alkaline condition whereas lime +vermicompost treatment (T5) successfully maintained the neutralized condition. Integrated treatment of lower doses of lime and vermicompost (T5) was found to efficiently promote the microbial population (rhizobium, phosphate and potassium solubilizing bacteria) and microbial respiration (basal and substrate induced respiration) activity, which might be attributed to the improvement soil microbial status. FDHA and DHA increased significantly with ‘lime’ as well as the ‘lime with vermicompost’ treatments in comparison to control. Interpretation: The incorporation of lower amount of lime and organic matter efficiently neutralizes the acidity and boosted up the microbial activities simultaneously that in turn might improve the soil health. The high cost to purchase the huge quantity of lime as recommended LR (9.25 tha-1) for studied soils turns the farmers uninterested to follow lime practice and interrupted the mitigation of soil acidity. Thus, the study might conclude that the integrated approach of lime application@½LR with vermicompost might successfully ameliorate the acid soils in terms of acidity as well as the soil microbial activities.

“…An alternative way to improve the physical and biological properties of soil and consequently to increase crop yields is to use organic fertilizers (alone or in combination with mineral fertilizers), such as animal litter, green manure or compost (Melkamu, 2012). The efficacy of organic fertilizers for improving maize growth, grain and dry matter yields, and/or harvest index has previously been demonstrated (Ademba et al, 2014(Ademba et al, , 2015Kidinda et al, 2015;Martins et al, 2017;Baghdadi et al, 2018).…”

Maize is an important food source worldwide and is of considerable industrial importance. Low maize yields are mostly due to low soil fertility, so expensive mineral fertilizers are often used to offset the lack of nutrients. Poultry litter (PL) is one of the most valuable and phosphorous-rich animal wastes. However, PL usually contains veterinary antibiotic residues, particularly fluoroquinolones (FQs), which may alter soil microorganism diversity and resistance patterns. In this study, we aimed to understand the impact of applying mineral (triple superphosphate-STP) or organomineral (STP with PL and reactive Bayovar phosphate with PL) fertilizers (130 or 260 kg/ha of total P 2 O 5) on the structure and composition of the soil bacteriome and on phosphate-mineralizing bacteria associated with the maize rhizosphere. Maize plants were sampled at 60 and 90 days after sowing and a clear rhizosphere effect was observed in all samples. No specific groups of bacterial genera predominated (>3% relative abundance) according to the different fertilizer treatments and most of the genera were shared among samples. Multivariate analyses of 16S rRNA sequences revealed clear clustering based on sampling time and distinct separation from bulk soil samples. Abundances of phosphate-mineralizing bacteria varied depending on the sampling time. We observed a positive effect on phytase activity under the 260 kg STP with PL treatment. Although the FQ enrofloxacin and its main metabolite ciprofloxacin were detected in PL, their concentrations in fertilized soils were below quantification thresholds. Quinolone resistance genes were not detected in the maize rhizosphere or bulk soil. Together, these results suggest that the rhizosphere effect, plant age and applied amounts of fertilizer are more influential on bacterial communities than the type of fertilizer used. Thus, application of PL as an organomineral fertilizer does not appear to have extensive impacts on the bacterial diversity of maize rhizosphere, so it could be an excellent option for enhancing maize production.
