Biological solubilization of phosphate rock by solidstate cultivation to produce eco-friendly fertilizers. Author(s): KLAIC, R.; GAVA JUNIOR, M.; RIBEIRO, C.; FARINAS, C. S. The objective of this work was to evaluate the solubilization of phosphorus from a phosphate rock by Aspergillus niger, under solidstate cultivation (SSC) in sugarcane (Saccharum officinarum) bagasse,... ... Repository: BDPA Publication year: 2021
Partial acidification of Arraias rock phosphate improves P use efficiency in tropical soils. Author(s): BENITES, V. de M.; DAL MOLIN, S. J.; SANTOS, J. A. C. The aim of this study was to evaluate the agronomic efficiency of partially acidulated Arraias rock phosphate. The experiment was conducted in a greenhouse at the University of Rio Verde, Rio Verde, G... ... Repository: BDPA Publication year: 2019
Corrective fertilization using rock phosphates as a strategy for improving the efficiency of maintenance fertilization in common bean. Author(s): CARVALHO, M. da C. S.; NASCENTE, A. S.; OLIVEIRA JUNIOR, A. de A field study was carried out in an acidic clayey Oxisol, during five growing seasons, aiming to evaluate the agronomic effectiveness of Bayóvar reactive rock phosphate (BRF) and Arraias sedimentary r... ...

Black oats (Avena strigosa Schreb) solubilize rock phosphate and provide phosphorus to the successive crop, grapevine (Vitis labrusca L. "Red Niagara"). Author(s): MELO, G. W. B. de; MORAIS NETO, J. A.; BORBA, D. R.; IWAMOTO, H.; OZELAME, K. P. C.; VIEIRA, J. L.; ZALAMENA, J.; NASCIMENTO JUNIOR, A. In grape production, cover crops play a key role in soil protection and nutrient cycling. Thus, since grapevine requirements for P are low, adequate management of cover crops may provide sufficient P... ... Repository: BDPA Publication year: 2018
