| 520 | _ | _ | |a The formation of calcium and potassium (hydrogen) phosphates from eggshell and KH2PO4 through a mechanochemical process was demonstrated successfully in an earlier study [1]. However, this newly developed material has not yet been tested as a potential fertilizer in a soil-plant system, being a prerequisite for validating the products’ fertilizer efficiency. The mechanochemical process was conducted using a BM500 Anton Paar ball mill, at 30 Hz, for 100 min. The most conventional sources of phosphorus for agriculture include potassium or calcium phosphate. However, the use of a combined source of calcium and potassium phosphate is still lacking applied studies. Therefore, greenhouse experiments of the final milled samples were conducted to evaluate the Ca, K and P fertilizing behavior under semi-controlled conditions, using 2 kg of sand as a growing substrate and Brachiaria brizantha as a model plant. Two sets of experiments were realized using 100 mg and 200 mg of P dm-3 [2]. From the harvested above ground dried biomass, it was observed that the milled samples showed an increase in biomass production and phosphorous and potassium uptake throughout each harvest, tending to stabilize in the third harvest. The negative controls, using either Bayovar rock or no fertilization did not show significant biomass production, phosphorous and potassium uptake. However, the obtained results of the positive controls using KH2PO4 showed a behavior of increasing biomass production and phosphorous and potassium uptake in the second harvest, mainly when 200 mg P dm-3 was applied. In conclusion, the milled sample provide a better nutrient management.References[1] R. Borges et al., doi: 10.1016/j.apt.2021.09.013.[2] R. Borges et al., doi: 10.1021/acsagscitech.2c00248. |
