“…Wafula et al [10] expressed that soils that contain sufficient plant available phosphorus necessitate the uptake of nitrogen from the soils most effectively due to their synergistic interaction. In this study, it was observed that, with net decrease in phosphorus in the soils after phosphorus treatments, sufficient absorption of phosphorus by plants signified synergy in the two nutrients' uptake by plants from the soils tested [13]. The net increase in soil nitrogen could be due to the addition of nitrogenous fertilizers into the soils or from organic matter breakdown already in the soils or via topdressing of calcium ammonium nitrate at active tillering and panicleinitiation stages after immobilizationmineralization processes taking place [14].…”

Phosphorus levels in the soil are easily fixed and rendered unavailable to plants even if they are found to be high and therefore, its influence on uptake of other nutrients such as nitrogen, and potassium cannot be overemphasized. In that view, an experiment was set out at KALRO-Mwea to investigate on the effect of phosphorus levels on soil properties and plant tissue nutrient contents of Nerica rice variety. The experiment was laid out in a Randomized Complete Block Design in splitsplit plot arrangement and replicated thrice. Two rice varieties (Nerica 11 and Nerica 4) formed the main plots and 4 phosphorus levels (0 kg P/ha, 25 kg P/ha, 50 kg P/ha and 75 kg P/ha) formed the sub plots. Highest net pH decreases of 0.20 and 0.22 units were recorded at 75 Kg haˉ¹ P 2 O 5 in season 1 and season 2 respectively, while the lowest net decreases of 0.12 and 0.16 were elicited at 50 Kg haˉ¹ P 2 O 5 treatment in season 1 and season 2 respectively. A net decrease was observed in all the CEC levels where phosphorus was applied in all the seasons in which the highest net Original Research Article

“…Manufactured water-soluble P fertilizers such as superphosphate are generally recommended to correct P defciency [7,8]. In addition, the intensifcation of agriculture requires additional P inputs to increase crop production and improves the P status of the soil to prevent further soil degradation.…”

Problems encountered in the management of upland acid soils, besides soil pH, are also low in phosphorus (P) content and less available to plants. The addition of organic acids (OAs) to the direct application of phosphate rock (PR) has not been widely studied yet and is expected to improve upland acid soil properties. The research aims to determine the effect of adding OAs on the direct application of PR to improve upland acid soil and increase maize yield. It was a greenhouse experiment using a randomized complete design in a factorial arrangement with three replications. The treatments consisted of four types of OA (citric, humic, succinic, and oxalic acid) and five OA concentration levels (0, 25, 50, 100, and 200 ppm). The hybrid maize (Zea mays L) was used as the test crop. The parameters observed were soil properties (pH, exchangeable H (H+), exchangeable Al (Al3+), exchangeable Ca (Ca2+), cation exchange capacity (CEC), available P (as P-Bray1)) and maize growth (plant heights and yield). The results show that the types of OA treatments had no significant effect on soil properties and maize yield; in contrast, the concentrations of OA levels were able to improve soil properties as indicated by a significant effect on pH, H+, Al3+, Ca2+, CEC, available P, and increased maize yield. An increase in soil pH due to the addition of OAs to the direct application of PR could increase Ca2+ and CEC and decrease Al3+ and H+, while increasing available P for plants. Although not significantly different, oxalic acid was able to improve the observed soil properties and maize yield, followed by citric, humic, and succinic acids. The maximum OA concentration was 126.9 ppm. We can say that the main finding of this research is that oxalic, citric, humic, and succinic acids at a concentration of 126 ppm can be applied to phosphate rock. In Indonesia, humic acid has been widely applied by farmers because it is easy to obtain. Therefore, it can be applied to phosphate rock.
