Residual effects of direct application of Burkina Faso

27/07/2016· Although phosphate rock (PR) deposits have been found in the region, they have not been well-utilised due to low reactivity, limited markets, lack of effective extension systems and other factors. However, previous studies indicate that direct application of these PRs are effective for lowland rice cultivation, although the residual effects of this application on rice yields have not been fully examined.

Acquisition of rock phosphate by combined application of

acquisition of rock phosphate in maize were examined on two soils (moderately acidic-pH 5 6 and alkaline-pH 7 8). On the two contrasting soils, FZB42 improved the P status and promoted plant growth by different mechanisms. On the acidic soil, a combination of ammonium-fertilization with FZB42 increased P-acquisition by Rock P solubilization via rhizosphere acidification but P-supply in the

Countries With the Largest Phosphate Reserves

23/03/2018· With the current rate of phosphate rock exploration and production, the reserves are likely to be depleted in the next 260 years if no new reserves are added. Consumption is likely to go up leading to a higher demand. Several steps have been put in place to reduce the over-reliance on phosphorus. Some of the programs include promotion of smarter fertilizer use and exploration of new mining
