      abstract     = {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:
