“…According to Troeh and Thompson (2005), when the soil pH is lower than 5.7, P is predominantly in the form of H 2 PO 4 − ions, which frequently reacts with or is adsorbed by Fe or Al compounds to form low-solubility compounds.…”

The production of biochar from organic residues promises to be an interesting strategy for the management of organic waste. To assess the effect of biochar on soil properties and the production and nutrition of common bean (Phaseolus vulgaris L.), three simultaneous experiments were conducted in a greenhouse with different biochar from organic residues (rice husk, sawdust, and sorghum silage) used as filtration material for swine biofertilizer. In ), arranged in a completely randomized design, with four repetitions. In the experiments, the use of biochar increased soil pH, cation exchange capacity, nutrient availability in the soil, and nutrient accumulation in grains. The biochar concentrations corresponding to the maximum production of grain dry matter of bean plants were 100, 68, and 71 L m −3 for biochar from rice husk filter (BRHF), biochar from sawdust filter (BSF), and biochar from sorghum silage filter (BSSF), respectively.

“…The principal rhizobial symbionts of soybean are species of Bradyrhizobium, Ensifer and Sinorhizobium (Jordan, 1982;Scholla and Elkan, 1984;Kuykendall et al, 1992;Chen et al, 1995;Gao and Yang, 1995;Appunu et al, 2008). Soybean also forms symbiotic relationships with other soil microbes including Agrobacterium (Youseif et al, 2014) and mycorrhizas (Sylvia et al, 1993;Troeh, 2006) which may also improve its fitness and yield.…”

Ethiopia remains a net importer of soybean partly due to low average yields which may be improved by inoculation with rhizobia and/or plant growth promoting rhizobacteria (PGPR). The functional characterisation of 231 rhizobacteria isolated from the rhizosphere of soybean grown in 102 soils collected from different pedo-climatic regions of Ethiopia was carried out. Isolates were initially characterised by Gram staining and then functionally for: indole-3-acetic acid production; phosphate solubilisation; growth on a nitrogen-free medium; and, resistance to the pathogenic fungus Fusarium oxysporum. A subset of 72 of the best performing isolates were tested in vitro for: production of bioprotectants; polysaccharide degradation; and their relative capacity to maintain growth in response to extremes of: temperature; pH; salinity; antibiotics; pesticides; and, heavy metals. Twenty isolates with the best PGPR potential were identified via 16S rRNA gene sequencing. Seventeen isolates were Gram-negative: Pseudomonas (7); Stenotrophomonas (5); Acinetobacter (3); Enterobacter (1); and Achromobacter (1). Gram-positive types were: Bacillus (2); and, Microbacterium (1). Of the six of the most promising PGPR tested on soybean plants, Achromobacter and Acinetobacter significantly enhanced soybean seed germination, seedling growth and plant vigour index compared to noninoculated plants.
