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

open access: yesLand 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.

Influence of notillage on carbon sequestration and erosion in Brazil [PDF]

open access: yes, 2004
Les sols constituent le plus gros réservoir superficiel de C (hors les roches carbonatées), environ 1500 Gt C, ce qui équivaut à presque trois fois la quantité stockée dans la biomasse terrestre, et deux fois celle de l'atmosphère.

Increasing the organic matter content of an Oxisol using rice husk compost : changes in decomposition and its chemistry. [PDF]

open access: yes, 2010
About 116 million Mg of rice husk, a byproduct of rice milling, are produced worldwide annually. Rice husk could be used as a soil amendment, but little attention has been given to the effect of its application and dynamic properties in soils.

Advances in organic UV filters for sunscreens over the past decade

open access: yesPhotochemistry 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 ...

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

open access: yesPlant 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

Dispersão de argila em microagregados de solo incubado com calcário Clay dispersion in microaggregates of soil incubated with limestone

open access: yesRevista Brasileira de Ciência do Solo, 2008
A compactação do solo restringe o rendimento de culturas de grãos. Dentre outros fatores, a calagem pode favorecer a dispersão de microagregados e a formação de camadas compactadas.

Least limiting water range and degree of compactness of soils under no- tillage

open access: yesBioscience Journal, 2015
The least limiting water range (LLWR) and degree of compactness (DC) can be useful indicators of soil physical quality and crop yield. This study focused on assessing of LLWR, DC and evaluation of critical values to crop growth of an Alfisol and Oxisol ...

Aplicação superficial de gesso num Latossolo de baixa acidez sob sistema plantio direto [PDF]

open access: yes, 2011
The conditions in which a favorable response to a gypsum application can be expected on crop yields are not clear. A 3-year field trial was carried out to evaluate the effects of gypsum application on soil chemical attributes and nutrition and yield of ...

Weed Management Influences the Accumulation of Organic Matter in the Soil and Productivity in Coffee Farming

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
The management of weeds can influence organic matter (OM) and organic carbon (OC) levels, impacting the productivity and sustainability of coffee plantations. This study aimed to evaluate OM and OC levels in coffee soils under different weed management practices and their influence on coffee tree physiology and productivity. The experiment featured six
