• Abstract

  Climate change represents a threat to the stability of agriculture, negatively impacting climate patterns and water resources. Integrated systems, especially those combining crop cultivation, livestock, and trees, are emerging as a promising approach to address climate uncertainties. Our objective is to develop strategies for achieving resilient and sustainable agricultural systems in the…

  The objective of the present work is to characterize the establishment of Tifton 85 and Jiggs grasses (Cynodon spp.) through the digital processing of images obtained with RPAS (Remotely Piloted Aircraft System) and, in parallel, apply an algorithm based on Support Vector Machine aiming at automatic classification. of land occupation in the initial phase of pasture formation. The project …

• Abstract

  Nitrogen (N) is an essential nutrient for forage grasses and it is often associated with the intensification of forage-based animal production systems. Biological nitrogen fixation and the use of of N-fixing bacteria is a low-cost and sustainable option for supplying plants with N, against a scenario of increased production costs and increased environmental pressures. However, there are n…

• Abstract

  The intensification of forage-based animal production systems is often associated with the use of nitrogen (N) which is an essential nutrient for forage grasses. In a scenario of increasing production costs and increasing environmental pressures, biological N fixation through N-fixing bacteria is a sustainable and low-cost option for supplying N to plants. However, there are no culture mo…

• Abstract

  The livestock industry is one of the major economic activities in Brazilian agriculture. In this context, the use of pastures as the almost-sole feed source makes the activity highly profitable due to low production costs. Brachiaria grasses correspond to 80% of the cultivated pasture areas in Brazil. In most pasture-based production systems, however, grazing management is extensive and o…

• Abstract

  Grazed pastures are the backbone of the Brazilian livestock industry and grasses of the genus Brachiaria are some of most used tropical forages in the country. Although the dependence on the forage resource is high, grazing management is often empirical and based on broad, non-specific guidelines, which hinders the competitiveness of the livestock industry. This results, in part of the lo…
