Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Boron extraction and vertical mobility in Paraná State oxisol, Brazil. [PDF]

, 2014
The deficiency or excess of micronutrients has been determined by analyses of soil and plant tissue. In Brazil, the lack of studies that would define and standardize extraction and determination methods, as well as lack of correlation and calibration ...

Papaya carotenoids increased in Oxisols soils

Agriculture and Natural Resources, 2017
Abstract The papaya fruit is healthy for humans as it contains high levels of antioxidants and provitamin A due to high lycopene and β-carotenes contents, respectively. The carotenoids were determined from papayas grown in three different locations—Kamphaeng Saen (KS), Sisaket (SK), and Tha Mai (TM)—and also the study investigated whether the Oxisols

STRUCTURAL QUALITY INDICATORS IN COMPACTED OXISOLS GROWN WITH CORN

REVISTA DE AGRICULTURA NEOTROPICAL, 2020
In the face of the elevated cost of economic and environmental order to recover degraded soil, the monitoring of the structural quality of the soil through physical and plant indicators is recommended. This way, this work aimed to verify which parameters may be used together with soil penetration resistance (PR), after compression induced by ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Physicochemical characterization of oxisol subjected to succession culture

Revista Brasileira de Engenharia Agrícola e Ambiental, 2023
ABSTRACT No-till farming is the practice closest to the concept of sustainable agriculture. The minimum soil movement and continuous contribution of crop residues to the farming system reduce erosion, mitigate the greenhouse effect, increase the organic matter content, and improve the physical and chemical quality of the soil.

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Extraction Kinetics and Molecular Size Fractionation of Humic Substances From Two Brazilian Soils

Journal of the Brazilian Chemical Society, 1999
In the present study, the extraction behaviour of humic substances (HS) from an Oxisol and a Mollisol from South Brazil, by using 0.1 and 0.5 mol L-1 NaOH and 0.15 mol L-1 neutral pyrophosphate solutions, respectively, was systematically studied.

Imazaquin sorption in surface and subsurface soil samples Sorção do imazaquin em amostras de solos superficiais e subsuperficiais

Pesquisa Agropecuária Brasileira, 2006
The objective of this work was to study the sorption and desorption of imazaquin, in surface and subsurface soil samples from Brazil. Sorption and desorption steps were carried out using batch equilibration and high performance liquid chromatography ...
