Agronomic and P recovery efficiency of organomineral phosphate fertilizer from poultry litter in sandy and clayey soils. The objective of this work was to evaluate agronomic and P recovery efficiencies of a granulated organomineral phosphate fertilizer (OMF) produced from poultry litter, compared with those of monoammon... ...

Laser-induced breakdown spectroscopy applied to the quantification of K, Ca, Mg and Mn nutrients in organo-mineral, mineral P fertilizers and rock fertilizers. Author(s): VILLAS-BOAS, P. R.; NOGUEIRA, A. R. de A.; MILORI, D. M. B. P. A low-cost laser-induced breakdown spectroscopy (LIBS) instrument equipped with a charge-coupled device (CCD) was tested in the atmospheric environment for the quantification of K, Ca, Mg, and Mn in s... ...

Long-term phosphate fertilization, mycorrhizal inoculation and historical land use influence on soybean growth and P uptake. O P é um nutriente chave no manejo da fertilidade de solos tropicais altamente intemperizados. Este trabalho foi conduzido com o objetivo de avaliar a influência da interação entre doses de P, inocula... ... Repository: BDPA Publication year: 2016
Analyzing the mobility in granular forms of P fertilizer in brazilians soils under laboratory conditions. Phosphorus is an essential nutrient for plant growth. Million of tones of P are applied to the soils annually. However, only a small fraction of the P applied with fertilizers is taken up by crops in... ... Repository: BDPA Publication year: 2013
Urochloa decumbens growth and P uptake as affected by long-term phosphate fertilization, mycorrhizal inoculation and historical land use in contrasting Oxisols of the Brazilian Cerrado. No manejo da fertilidade de Latossolos brasileiros altamente intemperizados e lixiviados, o P é o macronutriente mais limitante. Assim, conduziu-se um experimento em casa de vegetação, objetivando-se... ... Repository: BDPA Publication year: 2017
Heavy Metals in P Fertilizers Marketed in Brazil: Is This a Concern in Our Agroecosystems? Author(s): MARCHI, G. Abstract Fertilizers are key for sustainable use of land and for intensification of crop production, especially in tropical agroecosystems, which have soil fertility constraints that hamper agricultur... ...

Nitrous oxide emissions from a long-term integrated crop-livestock system with two levels of P and K fertilization. Author(s): CARVALHO, A. M. de; MARCHAO, R. L.; VILELA, L.; MALAQUIAS, J. V.; OLIVEIRA, A. D. de Abstract: Nitrous oxide (N2O) emissions resulting from nitrogen (N) fertilization have been docu- mented. However, no data on the effects of other nutrients, such as phosphate (P) and potassium (K), o... ... Repository: BDPA Publication year: 2022
Microbiological and biochemical attributes in low-fertiliy soil that received liming and p-fertilization. Repository: BDPA Publication year: 2013
Dynamic of Phosphorus Fractions in Typic Quartzipsamment Soil Cropped With Bean. Author(s): SERRA, A. P. Phosphorus is the most limited nutrient in Brazilian soils for plant growth, resulted of low availability and poor P content in bedrock. The aim of the study was to evaluate the dynamic of P fractions... ... Repository: BDPA Publication year: 2018
