Excessive use of chemical fertilizers in rice fields can reduce soil pH.Elemental P in acid soils is generally not available to plants because it is bound by Fe and Al elements; therefore, it is amina muaddi scarpe trasparenti necessary to make an effort to optimize the availability of P in the soil by improving soil pH with the addition of dolomite lime supported by inorganic fertilizers.This study aimed to determine the effect of dolomite and inorganic fertilizers on plant P uptake, the relationship between available P and phosphate-solubilizing bacteria population, and the effect of dolomite and inorganic fertilizer application on rice yield.This study used a randomized block design with eight tonic shower cap treatments and three replications.The results showed that the application of dolomite and inorganic fertilizer had a significant effect on plant P uptake and dry grain weight.

The population of phosphate-solubilizing bacteria was positively correlated with the availability of phosphorus in the soil.
