    • Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize 

      Appelhans, Estefania Carolina; Barbagelata, Pedro Anibal; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán (Wiley, 2020-02)
      Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in ...
    • Crop sequence and P fertilization effects on soil P fractions under no-tillage 

      Appelhans, Estefania Carolina; Novelli, Leonardo Esteban; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán; Caviglia, Octavio (Springer, 2021-05-27)
      Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ...
    • Is the lack of response of maize to fertilization in soils with low Bray1-p related to labile organic phosphorus? 

      Appelhans, Estefania Carolina; Barbagelata, Pedro Anibal; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán (Springer, 2021-01-07)
      The usual soil test phosphorus (P) neglects the P supply from labile organic P (Po) fractions, which could explain the nonresponse of maize (Zea mays L.) in sites with soil P testing below the critical level. We aim to ...
    • Predicting soil test phosphorus decrease in non-P-fertilized conditions 

      Appelhans, Estefania Carolina; Carciochi, Walter Daniel; Correndo, Adrián A.; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando; García, Fernando O.; Melchiori, Ricardo Jose; Barbagelata, Pedro Anibal; Ventimiglia, Luis Alberto; Ferraris, Gustavo Nestor; Vivas, Hugo Silverio; Caviglia, Octavio; Ciampitti, Ignacio A. (Wiley, 2020-02)
      Monitoring the availability of phosphorus (P) in soil under continuous cropping facilitates finding deficiency in crops and contributes to improving crop growth and nutrient management models. Soil P availability for crops ...
