2. Remote Sensing and Geostatistics Applied to Post-stratification of Eucalyptus Stands
ABSTRACT Brazil has many rural properties with unmanaged eucalyptus stands. These plantations are heterogeneous, presenting different tree sizes, advanced ages, and large wood volumes that can be quantified using forest inventories. The prediction error of dendrometric variables, mainly in highly heterogeneous areas, can be associated with inadequate forest

5. MODELING OF WATER, SEDIMENT AND PHOSPHORUS LOADS IN AN AGRICULTURAL WATERSHED IN SOUTHERN BRAZIL / MODELAGEM DO ESCOAMENTO, DA PRODUÇÃO DE SEDIMENTOS E DA TRANSFERÊNCIA DE FÓSFORO EM BACIA RURAL NO SUL DO BRASIL
Areas under intensive tobacco crop cultivation have been impacting the water balance and increasing soil erosion in Southern Brazil. Application of large amounts of mineral fertilizers, higher than the tobacco requirement, contributes to excessive phosphorus loads in soil and water bodies. The assessment of potential environmental impacts due to changes in l

10. Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region
The bell pepper is of high importance within the vegetable crops, thus becoming an alternative source of income for small producers and family farms. Potassium is the nutrient most absorbed by bell pepper and diffusion the main transport mechanism to the roots, although the mass flow can have significant contribution in the process under high potassium conce

Estoques de biomassa e de nutrientes de pousios enriquecidos com Inga edulis Martius em áreas com histórico de agricultura e de pecuária no Assentamento Tarumã-Mirím, Manaus- AM / Stocks of biomass and nutrients in forest fallow enriched with Inga edulis Martius in sites with a history of agriculture and pasture in the rural settlement Tarumã-Mirím, Manaus - AM
Deforestation rates of primary forests in the humid tropics have been growing intensively in recent years, due mainly to the development of shifting cultivation and extensive pasture. After forest fragmentation and conversion to agricultural use, the cleared areas of rainforest are usually abandoned so there is natural regeneration of vegetation and slow res

12. Caracterização da serrapilheira em caatinga preservada e mudanças no carbono do solo após o desmatamento sem queima
The Caatinga, a semi-arid ecoregion, is one of the most endangered Brazilian biome and transformed by human action. Despite its significant socioeconomic and environmental importance, few studies are directed to the sustainable management of this ecosystem. Accordingly, research related to the litter storage on the soil surface, total organic carbon (TOC) an
