Themes to highlight the importance of soils
AUTHOR: CLISTENES WILLIAMS ARAÚJO DO NASCIMENTO Professor at UFRPE and member of the Pernambuco Academy of Sciences Soils: the basis for sustaining life and the future of Brazil When we think of essential natural resources, such as water and air, it is easy to forget the soil, the invisible cloak under our feet that sustains […]
Plants that eat metals: species can change the future of mining and the environment
Clístenes Williams Araújo do Nascimento é professor da UFRPE e membro da Academia Pernambucana de Ciências Imagine a world where the solution to cleaning a soil contaminated with heavy metals such as lead, nickel and cadmium was in nature itself. This world exists, thanks to plants with a superpower: they “eat” metals. These are the […]
Do not rule out your worms, forward them!
In a text originally published on the Blog of the Brazilian Society of Zoology in May 2024, and recently published in the journal Biodiversity, the authors listed below make an appeal for researchers who work with or collect individuals from Edáfica fauna properly preserve and refer the material collected to institutions that are able to […]
Cover crops influence the physical hydric quality of a tropical sandy soil under no-tillage cotton cropping
HIGHLIGHTS The results of this study suggest that from the physical properties of the soil analysed, only the PR was influenced by the use of cover crops. At the surface physical limitations due to aeration occurred with Bd > 1.65 Mg m-3, while in the subsurface it occurred with Bd > 1.70 Mg m-3. Soil […]
Cropping and soil management systems effects on soil organic matter fractions in diversified agricultural fields in the Cerrado
HIGHLIGHTS Vegetation diversity helps maintain soil quality. Soil organic matter compartmentalization can be used to evaluate agricultural systems. Water-floatable light organic matter was effective in evaluating ]soil management. ABSTRACT Soil organic matter (SOM) dynamics can be significantly influenced by various cultivation practices, particularly under environmental and edaphic conditions that enhance and accelerate the transformations of […]
Saturated hydraulic conductivity and steady-state infiltration rate database for Brazilian soils
HIGHLIGHTS Mean values of hydraulic properties are presented for different soil classes and soil textural groups Fine textured tropical Brazilian and temperate soils reveal relevant differences in Ksat values An open database with soil hydraulic properties for Brazilian soils is presented ABSTRACT Soil saturated hydraulic conductivity (Ksat) and steady-state infiltration rate (SSIR) are essential and […]
Delineation of potential management zones for cowpea by factorial kriging and spatial Fuzzy C-Means of yield and soil chemical and texture properties
HIGHLIGHTS Maps of soil properties alone were not efficient in delineating management zones Factorial kriging analysis can be used in cokriging to estimate soil properties Factorial kriging and sFCM were efficient in delineating the two management zones Is possible to solve problems of multiple soil property maps with FK and SFCM ABSTRACT In precision agriculture, accurate […]
Effect of potassium rates and application methods in no-till on soil K availability and crop yield
HIGHLIGHTS The critical soil test level of K for southern Brazil is overestimated. The band-application of K increases the soybeans and wheat grain yield. The critical soil test value of K to achieve 90% soybean yield is 64 mg dm-3. Fertilization recommendations should consider the soil layer of 10-20 cm. ABSTRACT The combination of potassium […]
The State Center of Paraná, SBCS, promotes, from May 10 to 15, 2025, at the Rebouças Campus of the Federal University of Paraná, in Curitiba (PR), the IX Paranaense Meeting of Soil Science (RPCS). The event will have as its theme: “Diversity, functions and land uses: challenges and opportunities”.The organization is under the responsibility of […]
Until February 17, the pre-registration period for the XVI Brazilian Meeting of Soil Classification and Correlation (XVI RCC) is open. With the theme “What does Bahia have?”, The technical-scientific event will explore the Bahian pedestrian diversity, between October 25 and November 1 this year. It will be the first CCR made entirely in Bahian soils. […]
