1. SEQUÊNCIA DIDÁTICA PARA A PROMOÇÃO DE ESTUDO PRÁTICO E MULTIDISCIPLINAR COM MATERIAIS ACESSÍVEIS
Innovation and multidisciplinarity are the way to accelerate improvements in education, as well as the search for contextualized content. The multidisciplinarity between chemistry and Biology, allows to explore various contents, one of them is the environment. Works that offer alternatives to simpler experiments are of great help professors. In this context,

2. Modeling and prediction of sulfuric acid digestion analyses data from PXRF spectrometry in tropical soils
ABSTRACT Sulfuric acid digestion analyses (SAD) provide useful information to environmental studies, in terms of the geochemical balance of nutrients, parent material uniformity, nutrient reserves for perennial crops, and mineralogical composition of the soil clay fraction. Yet, these analyses are costly, time consuming, and generate chemical waste. This wor

3. Methane emission induced by short-chain organic acids in lowland soil
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, prop

4. A extraordinária história de vida de Ana Maria Primavesi
resumo Este artigo procura traçar os passos de Ana Maria Primavesi desde sua formação na Universidade de Ciências Rurais (Boku), em Viena, rumo ao entendimento (único) da complexidade da vida do solo, e como esse organismo vivo atua para o bom desenvolvimento agrícola. Percorre o caminho da sua infância e a sua formação acadêmica em meio à Segunda

5. Identification of patterns for increasing production with decision trees in sugarcane mill data
ABSTRACT: Sugarcane mills in Brazil collect a vast amount of data relating to production on an annual basis. The analysis of this type of database is complex, especially when factors relating to varieties, climate, detailed management techniques, and edaphic conditions are taken into account. The aim of this paper was to perform a decision tree analysis of a

6. Effectiveness of a rapid soil incubation method for determining potential acidity of soils in Rio Grande do Sul, Brazil
RESUMO: A acidez potencial do solo pode ser medida por dois métodos nos estados do Rio Grande do Sul (RS) e Santa Catarina (SC): índice SMP ou solução TSM (Tampão Santa Maria). A calibração destes métodos é feita pela incubação de solos por longos períodos (180 dias) com quantidades crescentes de CaCO3. A hipótese deste estudo é que é possíve

7. Mineralogical and chemical attributes of soils from the Brazilian Atlantic Forest domain
ABSTRACT: The Atlantic Forest is one of the most important and yet the most devastated Brazilian biome, occupying in the past the majority of the East Atlantic Coast. Therefore, a detailed knowledge of the soils near the coastal line influenced by this biome is essential for land use and management of these environments. The aim of this study was to acquire

8. Together yet separate: variation in soil chemistry determines differences in the arboreal-shrub structure of two contiguous rupestrian environments
ABSTRACT Rupestrian landscapes are characterized by vegetation mosaics comprised of different plant communities and strongly linked to environmental filters. These environments are nutrient-impoverished, and possess water retention deficits and high solar exposure. This study aimed to determine whether chemical properties of the soil shape the arboreal-shrub

9. Impact of an Alkaline Solution on the Chemistry, Mineralogy, and Sorption Properties of a Typic Rhodudult Soil
Abstract The preferred option for disposal of short-lived low and intermediate level radioactive wastes is a near surface disposal facility in which soil is one of the barriers that avoid radionuclide migration outside the controlled area. For construction of that kind of facility, concrete is widely used, and its interaction with water induces its degradati

10. An Evaluation of the Use of Statistical Procedures in Soil Science
ABSTRACT Experimental statistical procedures used in almost all scientific papers are fundamental for clearer interpretation of the results of experiments conducted in agrarian sciences. However, incorrect use of these procedures can lead the researcher to incorrect or incomplete conclusions. Therefore, the aim of this study was to evaluate the characteristi

11. Sugarcane trash levels in soil affects the fungi but not bacteria in a short-term field experiment
Abstract The sugarcane in Brazil is passing through a management transition that is leading to the abolition of pre-harvest burning. Without burning, large amounts of sugarcane trash is generated, and there is a discussion regarding the utilization of this biomass in the industry versus keeping it in the field to improve soil quality. To study the effects of

12. Soil Chemistry after Irrigation with Treated Wastewater in Semiarid Climate
ABSTRACT Soil irrigation using treated wastewater in the Brazilian semiarid region is a promising practice as this area currently faces water scarcity and pollution of water resources by domestic sewage. The aim of this study was to evaluate the use of treated wastewater in drip irrigation and its effect on the chemistry of soil cultivated with squash (Cucur
