Fitat (oswa hexakisphosphate inozitol) se yon gwo koule nan fosfat nan tè a. Fitat se rekalsitrant nan tè a akòz estrikti chimik li yo ki fè li aksesib nan plant intact. Olye de sa, fitat se kase desann nan Rizosfèr a, zòn nan nan tè dirèkteman anba enfliyans a nan rasin yo plant yo, libere fosfat inòganik pou absorption pa plant yo. Gen prèv ki montre limite plant kapab pann fitat menm si lage nan nan anzim soti nan rasin pwòp li yo.

Phytate (or inositol hexakisphosphate) is a major sink of phosphate in the soil. Phytate is recalcitrant in the soil due to its chemical structure that makes it inaccessible to plants intact. Instead, phytate is broken down in the rhizosphere, the zone of soil directly under the influence of the plant roots, liberating inorganic phosphate for uptake by plants. There is limited evidence that plants can breakdown phytate though the release of enzymes from its own roots.
