Title: Alfalfa Forage Production under Different Phosphorus Supply Strategies (Full Issue - BC 2005, No. 4)
By María A. Marino and Angel Berardo | ---------
| Alfalfa is one of the most important resources for high quality forage in the Pampas region of Argentina, with 1.75 million hectares (M ha) planted. Nonetheless, its yield potential is frequently restrained by inadequate soil phosphorus (P) supply. |

Title: Fertilizers to Sustain Production of 100 Million Metric Tons of Grain (Full Issue - BC 2005, No. 1)
By F.O. García, G. Oliverio, F. Segovia, and G. López | ---------
| Argentina is anticipating a large increase in its grain production potential. It is clear that improved soil nutrient balance is a key to sustaining this goal. |

Title: Alfalfa Production as a Function of Soil Extractable Phosphorus in the Semi-arid Pampas (Full Issue - BC 2004, No. 2)
By: Martín Díaz-Zorita and Daniel E. Buschiazzo | ---------
| This research provides insight into soil nutrient limitations for the main alfalfa producing soils of the semi-arid Pampas. Comparisons of critical extractable soil phosphorus (P) values were made among four common soil testing procedures. |

Title: Nutrient Management for a No-Till Rotation in the Pampas: Three Years of Field Trials (Full Issue - BCI 2003, No. 2)
By Agustín Bianchini, Martín Ambrogio, Santiago Lorenzatti, and Fernando García | | Crop economics can be improved by high yield crop management. Advantages include reduced impact of fixed costs and increased profit margins. Adequate crop nutrition optimizes the use efficiency of all resources and inputs involved in crop production. Knowledge of the extent of nutrient deficiencies pinpoints one set of the barriers to maximum economic yields. |

Title: Phosphorous Fertilization of Soybeans in Clay Soils of Entre Ríos Province (Full Issue - BCI 2002, No. 1)
By Pedro Barbagelata, Ricardo Melchiori and Osvaldo Paparotti | | Soil texture plays an important role in determining phophorous (P) avalability. This study examined the clay soils of Entre Ríos and determined a specific critical soil test P level for this region. |

Title: Corn Yield Response to Phophorous Fertilization in the Southeastern Pampas (Full Issue - BCI 2001, No. 1)
By Angel Berardo, Santiago Ehrt, Fernando D. Gratone, and Fernando O. García | | Corn is a major crop in agricultural systems of the southern Pampas of Argentina where soils are low in phosphorous (P) avalability. This research suggests a critical soil P level that can help define where profitable responses to P application are obtainable. |
