“…Both for P pnp and P rec , the treatments of 10% MAPR and 20% MAPR (except 10% MAPR in 2014) had equal effectivity for the three years, compared with 100% TSP (P < 0.05). It was in accordance with the results of the combined application of 50% Kodjari PR and 50% TSP that led to the equal effects on sorghum yields and P uptake in ferric Lixisol (Bonzi et al 2011). Initial PR has little effect on promoting plant growth, due to the negligible amount of WSP during short periods of crop growth, especially in neutral (pH 6.5) or even high pH soil (McLay et al 2000).…”

It is well known that mechanochemically activated phosphate rock (MAPR) could improve extractable phosphorus (P) (extracted in 2% citric acid) greatly in an ecological way. To evaluate the agronomic effectiveness of MAPR, we conducted a field experiment using spring maize in Luvisol (pH 6.47) soil in Northeast China for three consecutive years. Treatments consist of variation of P levels for substitution of triple superphosphate (TSP) (100% TSP, 10% MAPR, 20% MAPR, 50% MAPR, 100% MAPR). Compared with 100% TSP, all the combined applications of MAPR and TSP were as effective on straw yield. Treatments of 10% MAPR and 20% MAPR had similar effect on grain yield and P uptake, while 50% MAPR and 100% MAPR were significantly lower. For P partial nutrient productivity and apparent P recovery with the treatment of 20% MAPR had equal effectivity, likewise. For soil P<sub>Olsen</sub>, treatment of 10% MAPR was equally operative, while 20% MAPR had the similar performance only in the last year (i.e. 2016). It is concluded that 10–20% of TSP can be effectively replaced by MAPR without affecting spring maize yield in soil with neutral pH.

“…The RAE values of the BPR application were 79% for maize, 55% for millet, and 63% for sorghum 12 respectively. However, the direct application of the same BPR to lowland rice has been shown to have a relatively higher RAE value of 94% 53 .…”

“…BPRs, which are low-reactive PRs 10 for direct application, were also evaluated for various crops 12 , such as maize, millet, sorghum, cotton, groundnut, soybean, and rice. The RAE values of the BPR application were 79% for maize, 55% for millet, and 63% for sorghum 12 respectively.…”

It is known that phosphate rock (PR) deposits that account for most world's PR production are found in African countries. However, the rate of phosphorus (P) fertilizer use in Africa is typically low, despite the high requirement for application of the same there. This applies particularly to sub-Saharan Africa (SSA), where P deficiency has been suggested as one of the key constraints to crop production, despite the many PR deposits. There have been many excellent reviews on PR utilization in SSA, but hardly any have focused on its effectiveness in lowland rice cultivation. Given this lack of information, we reviewed the potential of PRs produced in the SSA region, focusing particularly on the utilization of PRs for rice cultivation in this region. Our review indicates that PR direct application in lowland rice resulted in high performance, regardless of the PR reactivity and the location investigated. A Phosphate Rock Decision Support System can help disseminate information on PR utilization in SSA; however, there is room for further improvement in predicting agronomic efficiencies in lowland rice cultivation, with consideration of the unique changes in soil condition such as the reduced condition that occurs in submerged paddy soils. In conclusion, the local PRs produced in SSA can be effectively utilized for direct application on lowland rice cultivation, hence the need to elucidate the PRs solubilization mechanism and therefore clarify the condition that maximizes the effect of local PRs direct application in SSA.
