Schematic model of current/traditional approach (A) and proposed/biotechnological approach (B). *On the current agricultural approach, world demand of P fertilizer is approximately 4.5 million tons, according to FAO (http://www.fao.org/3/a-i6895e.pdf). From these, 2.2 million tons are unavailable to crops (soil immobilization or surface runoff), and 2.3 million tons are harvested with the crops. On the proposed biotechnological approach, we suggest the reduction of up to 33% on the P fertilizer dose applied on the soil, along with PGPR inoculation. Such reduction on P fertilizer together with PGPR inoculation would result in less P unavailable to the crops. Nearly half of such unavailable P can be further solubilized by PGPR and uptaked by the crops, resulting in the same 2.3 million tons of harvested P (adapted from Roy et al., 2016).
