“…The use of novel management techniques and biotechnologies provide opportunities to improve P-use efficiency (Adhya et al, 2015;Rowe et al, 2016;Vandamme et al, 2016;Zheng et al, 2019). In addition to the development and use of novel strains of microbes with a high capacity for remobilizing stored P from crop soil (Adhya et al, 2015;Zheng et al, 2019), other technological improvements, such as novel crop genotypes (Rowe et al, 2016;Vandamme et al, 2016), may be used to improve P-use efficiency (Figure 7). Improved P-use efficiencies in soil and plants have also been achieved using combinations of novel and technologically improved traditional management techniques (Wang, Min, et al, 2016;Zheng et al, 2019), such as the application of biochar integrated with approaches of organic agricultural management (Chintala et al, 2014) and crop rotation (Lukowiak et al, 2016).…”

The availability of carbon (C) from high levels of atmospheric carbon dioxide (CO2) and anthropogenic release of nitrogen (N) is increasing, but these increases are not paralleled by increases in levels of phosphorus (P). The current unstoppable changes in the stoichiometries of C and N relative to P have no historical precedent. We describe changes in P and N fluxes over the last five decades that have led to asymmetrical increases in P and N inputs to the biosphere. We identified widespread and rapid changes in N:P ratios in air, soil, water, and organisms and important consequences to the structure, function, and biodiversity of ecosystems. A mass‐balance approach found that the combined limited availability of P and N was likely to reduce C storage by natural ecosystems during the remainder of the 21st Century, and projected crop yields of the Millennium Ecosystem Assessment indicated an increase in nutrient deficiency in developing regions if access to P fertilizer is limited. Imbalances of the N:P ratio would likely negatively affect human health, food security, and global economic and geopolitical stability, with feedbacks and synergistic effects on drivers of global environmental change, such as increasing levels of CO2, climatic warming, and increasing pollution. We summarize potential solutions for avoiding the negative impacts of global imbalances of N:P ratios on the environment, biodiversity, climate change, food security, and human health.

“…In addition, Bioch1, Bioch2, Bioch4, and Bioch7 selected strains, identified as Pseudomonas umsongensis (98%), Arthrobacter defluvii (98%), Microbacterium yannicii (99%), and Arthrobacter nicotinovorans (99%) revealed the highest production of IAA and also the ability to produce ACC deaminase. Some of these bacteria, along with bacteria of genus Streptomyces, Cupriavidus, and Variovorax also isolated in the present work, have recently been described (Zheng et al 2019), for their important properties of inorganic-phosphatesolubilizing-bacteria (iPSB). Bacteria of these genera have been used in experiments with Brassica napus in which soil was amended with several kinds of biochar enriched with them.…”

Biochar porous structure can be considered a shelter for soil beneficial microorganisms, as they can be protected against grazers or competitors. At this purpose, bacteria which colonize biochar-amended soil can be isolated, characterized, and tested in combination with chars deriving from different feedstocks, which can be used as inoculum carriers. In this work, cultivable bacterial strains were isolated from a three-year maize-biochar-amended soil. Morphologically different bacterial isolates were characterized by amplified ribosomal DNA restriction analysis (ARDRA) followed by 16S rDNA sequencing of those presenting different profiles. Twelve strains were characterized by multiple plant growth-promoting properties, as siderophores and acid-3indolacetic production, and ACC deaminase activity. An environmental scanning electron microscope was utilized to visualize in vivo bacteria biofilm formation on plant roots and biochar derived from a different feedstock. Most of the identified bacterial strains were found to be homologous with plant growth-promoting bacteria, among those Arthrobacter, Pseudomonas, Microbacterium, Bosea, and Variovorax genera, capable to synthetize high levels of IAA, produce siderophores and ACC deaminase. In addition, Bioch1, Bioch2, Bioch4, and Bioch7 strains were shown to colonize biochar deriving from a poplar wood feedstock and to create biofilms on plant roots. The results of this study indicate that beneficial soil bacteria can colonize a long-term biochar-amended soil and open the interesting possibility for the selected bacteria to be utilized as biochar carriermediated biofertilizers in agricultural soils.

“…Genome annotation produced 6,211 genes, of which 5,839 (94.01%) are protein-coding genes. Two gene clusters ( pqqEDCBA and pqqFECBA ) involved in pyrroloquinoline quinone (PQQ) biosynthesis were identified from the genome of strain 11-D3, which have been proven to be related to its capacity to solubilize inorganic phosphate (12). According to previous studies, the pqq operon is a key regulation factor for the expression of gluconic acid and 2-keto- d -gluconic acid, which are important for high-efficiency inorganic P solubilization in the genus Pseudomonas (13–15).…”
