1. Factors related to the economic performance of wheat commercial fields
ABSTRACT The variability of agronomic performance and of input use level of wheat commercial fields allows the identification of the factors with the greatest contribution to its economic performance. The objective of this work was to identify the main factors related to the variability of economic performance in wheat commercial fields in the Southern Regio

2. Carbon fractions and stock in response to solid and fluid organomineral fertilizers in highly fertile soils
Resumo: O objetivo deste trabalho foi avaliar o efeito da aplicação de fertilizantes organominerais e minerais em solos com fertilidade construída sobre o índice de manejo de carbono (IMC) e as frações e o estoque de carbono. O experimento foi realizado em um Cambissolo e em um Nitossolo sob sistema plantio direto, por três anos agrícolas. Os tratame

3. Response of dual-purpose wheat to nitrogen fertilization and seed inoculation with Azospirillum brasilense
RESUMO O uso de inoculantes contendo bactérias promotoras do crescimento vegetal é uma alternativa para aumentar a eficiência de uso dos fertilizantes nitrogenados. Em trigo de duplo propósito estudos avaliando a inoculação sobre a produção de forragem, palha e grãos são escassos. Nesse sentido, avaliou-se a produção de forragem e o rendimento de

4. Crop Yield Responses to Sulfur Fertilization in Brazilian No-Till Soils: a Systematic Review
ABSTRACT Sulfur (S) fertilization recommendations for grain crops in Brazil were formerly established from studies on crops with a low yield potential grown on soils under conventional tillage (CT). However, the subsequent adoption of no-tillage (NT) altered S dynamics in the soil, making it necessary to carefully evaluate the applicability of these S fertil

5. Nitrogen fertilization in top dressing for wheat crop in succession to soybean under a no-till system
ABSTRACT Agricultural intensification to improve wheat yield has increased the demand for nitrogen fertilizers. This study aimed to investigate the wheat response in succession to soybean due to application of nitrogen rates and sources in top dressing, as well as to determine the N rates of maximum technical yield (MTY) and maximum economic yield (MEY). A f

6. Sampling Layer for Soil Fertility Evaluation in Long-Term No-Tillage Systems
ABSTRACT In no-tillage (NT) systems, there is no plowed layer since the soil is not tilled. Thus, the soil layer for fertility evaluation can be defined as the one in which the fertility indices are affected by the surface application of lime and fertilizers and soil properties have the closest relationship with crop yields. The objective of this study was t

8. Inoculation with selected strains of Azospirillum brasilense and A. lipoferum improves yields of maize and wheat in Brazil.
Interest in the use of inoculants containing bacteria that promote plant growth is likely to increase in the coming years, due to higher costs of fertilizers, concerns over pollution and emphasis on sustainable agriculture. Although Brazil has a long tradition in research on nitrogen fixation in Azospirillum-grass associations, it has not led to recommendati

9. Doses de nitrogênio e formas de ureia em cobertura em genótipos de trigo
A utilização de cultivares mais responsivas na absorção e utilização de nutrientes, juntamente com práticas culturais adequadas e a utilização de insumos mais eficientes são estratégias para reduzir custos e maximizar a produção e a qualidade do trigo produzido no Brasil. O objetivo do trabalho foi avaliar o efeito de doses de adubação nitroge

10. Hematological and enzymatic evaluation and measurement of metal levels in occupational exposure to agricultural chemicals and fertilizers. / Avaliação hematológica, atividade enzimática e níveis de metais na exposição ocupacional aos defensivos agrícolas e fertilizantes
Advancements in the agrochemical industry associated with new seeding techniques make it possible for the country to reach annual crop records in production. However, the chemicals and fertilizers used for increasing productions are by no means harmless to human health. Repeated and inadequate exposures to such chemicals may result in their absorption and ca

11. DESEMPENHO DE DOIS PROTÓTIPOS DE SEMEADORAS-ADUBADORAS PARA PLANTIO DIRETO / PERFORMANCE OF TWO SEEDER-FERTILIZERS PROTOTYPES FROM DIRECT SEEDING
With the objective of evaluating the acting of two seeder-fertilizer prototypes for the direct seeding system, works were developed in field conditions and evaluation track according to international standard. The experiments were conduced in the years of 2007 and 2008, evaluating two prototypes, one of precision seeder-fertilizer and another of multiple see

12. AGRICULTURE OF PRECISION: MANAGEMENT OF THE FERTILITY WITH APPLICATION OF THE VARIED RATE OF FERTILIZERS AND ITS RELATION WITH CROP YIELDS / AGRICULTURA DE PRECISÃO: MANEJO DA FERTILIDADE COM APLICAÇÃO A TAXA VARIADA DE FERTILIZANTES E SUA RELAÇÃO COM A PRODUTIVIDADE DE CULTURAS
The agriculture of precision has been an important tool for the characterization of the spatial variability of soil attributes and crops. Thus, there is many options to elaborate thematic digital maps that can improve the soil and crop management. In this work, two croplands that has been managed with precision agriculture during several years were selected.
