Improving Phosphate Acquisition from Soil via Higher Plants …

Phosphate (P) is the plant macronutrient with, by far, the lowest solubility in soil. In soils with low P availability, the soil solution concentrations are low, often below 2 [µmol P/L]. Under these conditions, the diffusive P flux, the dominant P transport mechanism to plant roots, is severely restricted. Phosphate is sorbed into various soil solids, Fe/Al oxides, clay minerals …

What Are the 15 Natural Phosphorus Sources for Your Plants?

Rock Phosphate. Rock phosphate is difficult to break down in soil because the calcium and phosphorus atoms are securely bound together in the rocks. Phosphorus is essential for plant health and growth, yet it is difficult for plants to absorb. The N-P-K ratio of 0-2-0 in rock phosphate makes it an excellent phosphorus source.

Plants assimilate only inorganic phosphate (Pi) from the soil; this chemical form is poorly utilized and has low mobility in soils (McLaughlin et al., 2011).Due to precipitation, mineralization, and microbial activity, soil Pi concentrations rarely exceed 5 µM, and plant tissue Pi concentrations are typically 5–20 mM (Pierre and Parker, 1927, Raghothama, 1999).

1 Introduction. The phosphorus (P) bioavailability in soils is low (Filipelli, 2008).Due to binding of phosphate to organic and inorganic soil particles, the concentration of P in the soil solution is generally low (Pierre and Parker, 1927; Hinsinger, 2001; Smith et al., 2003).Phosphate in the soil solution is sufficient to feed rapidly growing plants for only a few days (Mengel and …
