“…No significant correlation was found between soil organic matter, N uptake, and P uptake by mungbean plants (Figure 6). Our results are in contrast with Hussain et al (2021), who reported that the relationship between soil organic matter, N and P uptake in PSB inoculated soil was strong, meaning that PSB in soil regulated the mineralization of organic matter, subsequently improving NP uptake.…”

“…Therefore, research for ecofriendly alternatives is needed. Highly efficient phosphate solubilizing bacteria (PSB), applied either alone or in combination with chemical fertilizers able to significantly increase phosphorus content in the plant rhizosphere and crop yield, could represent an ecofriendly strategy ( Hussain et al., 2021 ). Moroccan phosphate mines are an unexplored biotope and could represent an interesting source of well adapted phosphate solubilizing microorganisms.…”

Most agricultural soils are facing limited phosphorus availability that challenges modern agriculture. Phosphate solubilizing microbia (PSM) has been explored extensively as potential biofertilizers for plant growth and nutrition, and harnessing phosphate rich areas could provide such beneficial microorganisms. Isolation of PSM from Moroccan rock phosphate led to the selection of two bacterial isolates, Bg22c and Bg32c, showing high solubilization potential. The two isolates were also tested for other in vitro PGPR effects and compared to a non-phosphate solubilizing bacterium Bg15d. In addition to phosphates, Bg22c and Bg32c were able to solubilize insoluble potassium and zinc forms (P, K, and Zn solubilizers) and produce indole-acetic acid (IAA). Mechanisms of solubilization involved production of organic acids as demonstrated by HPLC. In vitro, the isolates Bg22c and Bg15d were able to antagonize the phytopathogenic bacteria Clavibacter michiganensis subsp. michiganensis, causal agent of tomato bacterial canker disease. Phenotypic and molecular identification by 16S rDNA sequencing demonstrated delineation of Bg32c and Bg15d as members of the genus Pseudomonas and Bg22c as member of the genus Serratia. The two isolates Bg22c and Bg32c were further tested either alone or in a consortium and compared to the non-P, K, and Zn solubilizing Pseudomonas strain Bg15d for their efficacy to promote tomato growth and yield. They were also compared to treatment with a conventional NPK fertilizer. Under greenhouse conditions, Pseudomonas strain Bg32c remarkably improved the growth of whole plant height, root length, shoot and root weight, number of leaves and fruits, as well as fruit fresh weight. This strain also induced stomatal conductance enhancement. The strain also improved total soluble phenolic compounds, total sugars, protein, phosphorus and phenolic compounds contents compared to the negative control. All increases were more pronounced in plants inoculated with strain Bg32c in comparison with control and strain Bg15d. The strain Bg32c could be considered a potential candidate for formulation of a biofertilizer in order to improve tomato growth.

“…The results revealed that the application of P with HA decreases the P-fixation and increases the water-soluble P availability to plants by making its soluble complexes and its uptake improves the storage of photosynthates in the plants. The addition of humic acid and FYM have direct as well as indirect effects on crop growth and yield, as they play an essential role in supplying and cycling nutrients in the soil and releasing the insoluble pool by its solubilising effect under the P-deficit conditions (Hussain et al, 2021;Kumawat et al, 2021). The FYM and humic acid, besides releasing their own nutrient, increases the nutrient use T 1 +PA 3 ( Phytase+HA)+SSP @ 50% recommended soil test dose FYM-Farmyard manure @ 12.5 t ha -1 , HA-Humic acid @ 3 kg ha -1 , Phytase @ 2 kg ha -1 and PSB-Phosphorus solubilising bacteria @ 2 kg ha -1 .…”

Background: Over the years, the excessive P fertilizer application to crop fields resulted in the build up of insoluble phosphorus pool in soil known as legacy phosphorus. This represents a vast and largely untapped resource in soil. The current study was conducted to evaluate the potential of some P activators (Phosphorus solubilising bacteria, phytase, humic acid, farmyard manure) on increasing the plant availability of legacy P in calcareous soil. Methods: A field experiment was conducted with maize hybrid COH(M) 6. The P activators were combined and applied along with the different doses of P fertilizer (100%, 75% and 50% soil test dose of single super phosphate). Result: Farmyard Manure (FYM) application with Humic acid (HA) showed the increased Olsen P under 100% and 75% of P application. The phosphorus activation response of FYM+HA applied plots showed a higher value than other treatments. The maize yield and P uptake obtained with FYM and HA were statistically comparable at 100% and 75% soil test dose of P. The findings have illustrated that even the reduced amount of P fertilizer application can support the crop growth due to the release of legacy P if they are applied along with P- activators such as FYM and HA.
