Phosphorus (P) fertilizer is essential for crop production, but reductions are warranted to conserve resources and minimize environmental impacts. Several lab, glasshouse, growth chamber, and field studies have been performed over the past seven years with a new P fertilizer (Carbond P; CBP; Land View Fertilizer, Rupert, ID, USA) in calcareous, low OM soil. This paper will be a review of a portion of that data. Studies comparing CBP to ammonium polyphosphate (APP) and monoammonium phosphate (MAP) applied to soil show season-long increases in P solubility for CBP in many soils. Glasshouse and field studies with maize (Zea mays L.), dry beans (Phaseolus vulgaris L.), potato (Solanum tuberosum L.), sugarbeet (Beta vulgaris L.), and wheat (Triticum spp.) resulted in significantly greater yields and/or crop quality in 19 of the 41 studies—with no negative responses at what would be considered low to moderate rates of CBP. Low rates of CBP show increases in biomass and P concentration when compared to APP and MAP at similar rates. The effect largely disappears at high rates. When examining only trials with low soil test P (<20 mg kg-1 Bicarbonate extractable P for potato and <12 mg kg-1 for all other crops), greater responses occurred in nearly every trial for CBP over APP when comparing low rates of these materials—showing an increase in P use efficiency. The average yield increases were 11% and P uptake increases were 14%. Carbond P is an enhanced efficiency fertilizer that often increases yields and crop quality and almost always increases P uptake in plants compared to traditional fertilizers when applied at low rates on calcareous soils with relatively low soil test P.
