“…showed the highest phosphate solubilization zone (16.00 mm) in PVK agar just as a documented by Lazcano et al (2013). The reports of Zhang et al (2012) and Yang et al (2016) have also shown the positive effect of organic manure on the soil microflora. Furthermore, Kohler et al (2015) showed that organic manure significantly increased shoot biomass by 64%.…”

A field experiment was conducted between August and October, 2014 at the Department of Microbiology to assess the effect of organic and inorganic fertilizers on the population and activities of Phosphate Solubilizing Bacteria (PSB) in the rhizosphere of maize variety BR9928DMRSR-Y. Three treatment groups were used in the study and these were: Groups which received applications of organic fertilizer (Poultry litter) alone, groups which received applications of inorganic fertilizer (NPK) and the third group which was the control (CON) did not receive any fertilizer application. A total of twenty-three bacteria were isolated and in-vitro screening was done for different phosphate solubilization activity. The study revealed that maximum population of total heterotrophic bacteria (26.8×10 9 CFU/g) was obtained with organic fertilizer (OM) tre atment. Among the different PSB isolates, OMPSB had the highest bacterial count of 10.2×10 9 . The lowest bacterial populations were obtained from IFPSB with 6.0×10 9 CFU/g. Out of the 23 PSB isolates, 18 were positive for phosphate solubilization with OMPSB8 showing the highest zone with 16 mm. Results showed that application of organic fertilizers enhanced the bacterial population and also showed increase in phosphate solubilization activities in rhizosphere soil compared to NPK and control treatments. This shows that organic fertilizers would be able to sustain the soil fertility for a longer period by meeting the demand of present and future generations.

“…Indeed, the fraction of soil carbohydrate extractable with hot water (representing about 6-8% of the total carbohydrate content), supposedly corresponding to microbial mucilage, has been shown to be correlated with aggregate stability (Haynes and Francis 1993). This could explain why in the case of our crop rotation treatment, which is known to favour microbial density and activity (Yang et al 2016), the percentages of bacterial micro-aggregates were also the highest. Mycorrhizal and saprophytic fungi are the known to be the most important soil microorganisms involved in the formation and stabilization of aggregates, but bacteria can also have profound influences on aggregation especially at the microscale (Six et al 2004).…”

Nickel (Ni) agromining aims to phytoextract heavy metals using hyperaccumulators whilst at the same time rehabilitating ultramafic soils. After removing the bioavailable metal, ultramafic soils are improved in terms of their agronomic properties with the aim of future agricultural uses. The low fertility of ultramafic soils can be compensated by integrating legumes already used in traditional agro‐systems because of their importance in soil nitrogen enrichment. However, few studies have evaluated the potential profits of legumes on Ni agromining and their potential benefits on soil biological fertility. Here, we characterized the effect of a crop rotation with two plants, a legume (Vicia sativa) and a hyperaccumulator (Alyssum murale), on the phytoextraction efficiency and on soil structure and biofunctioning. A pot experiment was set up in controlled conditions to grow A. murale and four treatments were tested: rotation with V. sativa (Ro), fertilized mono‐culture (FMo), non‐fertilized mono‐culture (NFMo) and bare soil without plants (BS). No significant difference was found between the Ro and NFMo treatments for the dry biomass yield. However, the Ro treatment showed the highest Ni concentrations ([Ni]) in A. murale shoots compared to FMo and NFMo treatments. The Ro treatment plants had more than twice as many leaves [Ni] compared to FMo. Soil physico‐chemical analyses showed that the Ro treatment was better structured and showed the highest presence of bacterial micro‐aggregates, as well as less non‐aggregated particles. Legumes integration in Ni‐agromining systems could be a pioneering strategy to reduce chemical inputs and to improve soil biofunctioning and thus fertility.

“…Kao posledica nedovoljno razvijenog stočnog fonda kojim bi se mogle obezbediti potrebne količine stajnjaka, neophodno je uvođenje alternativnih organskih đubriva u cilju očuvanja plodnosti zemljišta, ali i njegovih fizičkih svojstava. S toga su međuusevi našli značajnu primenu u sideraciji, odnosno njihovom gajenju za zelenišno đubrivo, a prema Yang et al, (2016) imaju značajnu ulogu u održivoj poljoprivredi. Ćupina et al, (2004) ističu da međuusevi indirektno utiču na povećanje zdravstvenog stanja zemljišta, utičući pozitivno na strukturu zemljišta, povećavajući infiltraciju, poljski vodni kapacitet i smanjujući sabijenost zemljišta.…”
