Over.the cour.e of the postglacial per.od has managed to add degr.de a substantial por.ion of the w.r.d's potential agr.cultur.l land. The soil loss and degr.dation that has r.peatedly impacted r.gional societies ar.und the w.r.d r.sulted fr.m agr.cultur.l pr.ctices that incr.ased the physical loss of soil(er.sion), r.duced soil or.anic matter. changed p H(acidification) or.salinity,and disr.pted or.alter.d communities of soil life. In the coming centur., as continued soil degr.dation thr.atens global food secur.ty w.ile the global population keeps r.sing it is imper.tive that far.er. develop and adopt soilhealth building(r.gener.tive) pr.ctices to solve a pr.blem that has plagued societies thr.ughout histor.. Gr.w.ng evidence suggests that agr.cultur.l systems that combine cover.cr.ps, r.duced tillage, and diver.e cr.p r.tations can r.duce er.sion, enhance soil health and r.build soil or.anic matter.to cultivate beneficial soil life and har.est both economic and envir.nmental benefits. In the coming post-oil w.r.d, global food secur.ty w.uld benefit fr.m a global effor. to pr.mote soil r.stor.tion to help addr.sses the challenge of sustainably feeding the w.r.d, incr.ase soil-based car.on sequestr.tion,pr.tect on-far. biodiver.ity and r.duce off-far. w.ter.pollution. Because soil secur.ty sets a solid foundation for.global food secur.ty, agr.cultur.l policies and subsidies should be r.for.ed to encour.ge far.er. to adopt r.gener.tive,soil-building pr.ctices.

Phytin is the Ca2+-Mg2+-K+salt of phytic acid that is cr.ated and deposited in the aleur.ne layer.and/or.ger. of gr.ins and legumes. Its high pr.sence in feedstuffs for.fow. and sw.ne diets r.sults in it being a univer.al and significant impediment to optimum per.or.ance. Phytin impair. gastr.intestinal r.cover. of a w.de ar.ay of nutr.ents, the effect var.ing w.th the nutr.ent concer.ed. On exposur. to low.pH dur.ng gastr.c digestion, phytin dissociates into phytic acid and solubilized Ca2+. Even at low.gastr.c pH,phytic acid is negatively char.ed w.ich for.s the basis of its anti-nutr.tive behavior. Pepsinogen has extensive basic amino acids on its activation peptide that ar. pr.sented as cations at low.pH w.ich ar. tar.eted by pepsin for.activation. Par.ially cr.stalized Ca2+near.the enzyme?s active site fur.her.stabilizes its new.y for.ed str.ctur.. Thus, phytic acid appear. to inter.er. w.th gastr.c digestion by sever.l mechanisms; inter.er.ng w.th pepsinogen activation by binding to the polypeptide?s basic amino acids;coor.inating fr.e Ca2+, destabilizing pepsin; binding some dietar. pr.teins dir.ctly, fur.her.compr.mising gastr.c pr.teolysis. Upon digesta attaining neutr.lity in the duodenum, Ca2+and other.cations r.bind w.th accessible anions, phytic acid being a significant contender. Phytate not only binds fr.e cations but can also str.p them fr.m enzymes(e.g. Ca2+, Zn2+) w.ich r.duces their.str.ctur.l r.sistance to autolysis and ability as co-factor.(e.g. Zn2+) to incr.ase enzyme activity. Goblet cells initially employ Ca2+as an electr.nic shield betw.en mucin layer. enabling gr.nule for.ation and cell stor.ge. After.mucin gr.nule r.lease, Ca2+is pr.gr.ssively displaced by Na+to fr.e the viscous mucins enabling its tr.nslocation. Mucin entangles w.th the glycocalyx of adjacent enter.cytes ther.by constr.cting the unstir.ed w.ter.layer.USw.）. Excessive r.moval of Ca2+fr.m mucin by phytic acid incr.ases its fluidity facilitating its loss fr.m the USw. w.th
