Analysis of fire risk and fire management in the Bilibiza Administrative
Post, Mozambique
- Authors: Dalmildo Agostinho Máquina, Ivan Abdul Daude, Adérito da Silva Jeremias, Caetano Serrote, Adélio Zeca Mussalama
  Pages: e03 - e03
  Abstract: Forest fires contribute to forests degradation. For this reason, it is essential to know the factors that favour its occurrence and map susceptible areas to allow the development of specific programs for fire management. In this study, we used Geographic Information Systems to analyze the risk of fire occurrence in the Administrative Post of Bilibiza, in Cabo Delgado province, Mozambique, in order to allow its management. Risk maps were produced based on variables that affect fire occurrence and spread through the Hierarchical Analysis Process method. Eighty households from three localities were also surveyed. Most of the area (78%) has a moderate risk of fire, 13% has high risk and 9% has low risk. Practices that influence fire frequency are hunting (85%), agriculture 82% and charcoal production (47%). About 84% of the community has neither knowledge nor information about national law regarding fire management. Awareness campaigns should be promoted to reduce fire occurrences in the Administrative Post of Bilibiza.

Aspects of soil fertility and nutrition of Pinus taeda L: A review
- Authors: Matheus Severo de Souza Kulmann, Grasiele Dick, Maristela Machado Araujo, Gustavo Brunetto, Mauro Valdir Schumacher
  Pages: e02 - e02
  Abstract: The cultivation of the genus Pinus spp. in Brazil occupies an area of 1.7 million hectares in 2020. Pinus is considered a socioeconomic component, which helps maintain the development of the southern region of the country and the national supply chain. However, the areas destined for pine cultivation usually have acidic soils and low natural fertility, which reduces the nutrients availability, negatively influencing the crop development. However, it is not known if Pinus responds positively to mineral fertilization, nor what is the nutrient of greatest demand regarding plantation development. Thus, the objective of this review is to explore which nutrients are of greatest nutrient need and therefore most responsive to pine growth and productivity. Thus, this review aims to establish a discussion on the importance and current plantation of Pinus taeda, along with answers on fertilization and nutrition of the crop, obtaining data from articles found in scientific databases of international literature, to better inform fertilization practices for this little studied crop. We have seen that mineral fertilization aims to optimize the pine growth, seeking to meet the physiological needs of the plants and thus achieve maximum crop productivity. However, the literature shows that many times the pine does not respond expressively in growth when subjected to mineral fertilization. Thus, studies that consider the effects of nutrient application to the pine crop, over time, are required to better conclude whether the pine crop responds to the nutrient supply.

Evaluación del crecimiento de plántulas de Eucalyptus tereticornis Sm.
en diferentes sustratos
- Authors: Ignacio Pablo Traversa
  Pages: e01 - e01
  Abstract: El género eucalipto se planta de forma diversificada en el mundo entero. La especie E. tereticornis tiene importancia económica en Uruguay. El objetivo de la investigación fue evaluar en laboratorio el crecimiento de plántulas de semilla, en cuatro tratamientos de diferentes sustratos: arena, arena con fertilizante, sustrato comercial y sustrato comercial con fertilizante. Fueron analizadas las variables período de germinación, sobrevivencia, largo y diámetro del tallo y largo de las raíces. Los resultados fueron procesados por ANOVA y contrastes de medias. Se encontró que el substrato comercial fue el que proveyó el más rápido crecimiento.
