“…Wang et al (2010) highlighted the genetic improvement for P efficiency in soybean using radical approaches and likewise Li et al (2009) found relationship between leaf acid phosphatase activity and either P nutritional status or P efficiency in rice. Functional genomic studies on soybean have provided valuable insights using high-throughput sequencing technologies on our current understanding of the adaptation of soybean plants to limited P availability (Zogli et al 2017).…”

Phosphorus (P) sources are limited around the globe making it unsustainable with present farming practices. This necessitates the development of more phosphorus efficient crops while monitoring P status. Groundnut (Arachis hypogaea L.) is a major crop in Southern Andhra Pradesh, India where soils are light textured and less fertile. Twenty groundnut genotypes were evaluated under a pot culture experiment conducted at Regional Agricultural Research Station, Tirupati, Andhra Pradesh, India during kharif, 2016 grown using standard crop recommended practices in P-sufficient (control) and in Pdeficient conditions. Leaf Acid phosphatase activity and leaf P content were monitored after 60 days of sowing while kernel P and pod yields were recorded at harvest and estimated using standard protocols. Results showed that under P deficient conditions, genotypes TCGS 1616, TCGS 1622, TCGS 1624, TCGS 1517 and Greeshma had higher leaf P accumulation (between 0.20 % to 0.24 %) in comparison to others. Genotypes TCGS 1616, TCGS 1624, and TCGS 1517 reported high kernel P when compared to others under P starved conditions. Likewise under deficient soil P conditions, TCGS 1528, TCGS 1624, TCGS 1517 and Greeshma (range 2.71-4.45 µmoles hr -1 g -1 ) demonstrated having lower leaf acid phosphatase content in leaves when compared to other genotypes. Only TCGS 1624, TCGS 1616 and Greeshma had lower leaf acid phosphatase while at the same time having higher accumulation of leaf P and highest pod yield followed by TCGS 1517 suggesting that P starvation was better coped by these genotypes and hence can be recommended in soils deficient in P. Leaf acid phosphatase activity correlated negatively with P content in leaves (r = -0.73) similar to those reported for soybean cultivars in Brazil. There is potential for breeders in accelerating identification of markers to specific traits that would be suitable for monitoring P status and manage nutrient application.

“…The most typical root responses of plants in increasing the solubilisation of soil P is the decrease in rhizosphere pH by the release of H + and phosphatases acids to the rhizosphere (M'sehli et al, 2012). Enhancement of acid phosphatase activity (APases) under P starvation conditions has been demonstrated for N 2 -fixing legumes including Vicia faba (M'sehli et al, 2012), Lupinus albus and Glycine max (Hinsinger et al, 2011;Zogli et al, 2017). Studies in Vicia faba and Vicia sativa showed that P deficient plants increased both extracellular APases, which are involved in hydrolysis of soil's various organic phosphate monoesters and intracellular enzymes acting in the remobilization of P i from rich P components inside the plant cell (M'sehli et al, 2012).…”

Nowadays, the agriculture’s target is to reach the amount of crop production that can cover the need to feed growing world population with the crucial challenge of respecting the environment. Several environmental constraints are limiting world agricultural production, mainly the preponderance of calcareous soils suffering from ferric and phosphoric deficiencies. In those soils, legumes were considered as an alternative solution to retrieve a fertile soil without the abusive use of chemical fertilizers. The ability to establish a symbiotic association with nitrogen-fixing soil bacteria is the way used by legumes to restore soil organic matter and to improve soil fertility. Legumes remain a source of healthy food while respecting the environment. This paper describes the importance of legumes for Fe and P deficient soils management through sustainable practices.

“…A study by Kahiluoto et al [17] showed that Po from organic inputs could be more available than P from chemical fertilizers. However, this availability was affected by rhizosphere microbiome and root traits [18][19][20]. Therefore, a better understanding of the interactions between Po forms, root traits, and rhizosphere microbiomes, can help to better manage P fertilization.…”

Moving toward more sustainable sources for managing phosphorus (P) nutrition in agroecosystems, organic phosphorus (Po) derived from organic inputs and soil is increasingly considered to complement mineral P fertilizer. However, the dynamics of P added by organic input in soil-plant systems is still poorly understood and there is currently no clear information on how the Po composition of these amendments determines P availability through interactions with the soil microbiome and root traits. Here, we review the main mechanisms of rhizosphere microbiome and root traits governing the dynamics of organic input/soil-derived Po pools in the soil-plant system. We discuss the extent to which the major forms of Po derived from organic input/soil can be used by plants and how this could be improved to provide efficient utilization of organic inputs as potential P sources. We provide new insights into how a better understanding of the interactions between Po forms, root traits, and rhizosphere microbiomes can help better manage P fertilization, and discuss recent advances in the mobilization and recovery of Po from organic inputs. We then develop proposed strategies in agroecology that could be used to improve Po utilization, specifically by better linking plant traits and Po forms, and developing new cropping systems allowing more efficient Po recycling.
