Introduction: The greenhouse gas balance is a central theme in discussions related to forest ecosystems. In this context, the present study evaluated the impact of five eucalyptus harvest residue management systems on atmospheric C-CO retention in soil, greenhouse gas (GHG) emissions, and the global warming potential (GWP) in plantations.

Methods: The management systems examined were: AR - all harvest residues retained on soil; NB - harvest residues kept on soil, except bark; NBr - harvest residues kept on soil, except branches; NR - all harvest residues (bark, branches, leaves) removed; NRs - all residues from the previous rotation and new plantation litter removed using shade cloth.

Article Synopsis
  • This study explores the use of portable X-ray fluorescence (pXRF) spectrometry for analyzing plant nutritional status in Brazil, focusing on the cultivation of certain plant species over millions of hectares.
  • It aims to differentiate plant clones and predict the content of eleven essential nutrients in leaves (such as nitrogen, potassium, and magnesium) to speed up the identification of nutrient deficiencies.
  • The study found that pXRF can effectively predict nine of the eleven nutrients and offers a more efficient and eco-friendly alternative to traditional testing methods, suggesting it could be beneficial for other crops as well.
