Influência de formas do relevo em atributos físicos de um latossolo sob cultivo de cana-de-açúcar Influence of the relief forms on physical attributes of an oxisol cropped with sugarcane

open access: yesCiência Rural, 2006
Os atributos físicos do solo variam em função das formas do relevo e sofrem influência da mineralogia da fração argila e do manejo da cultura de cana-de-açúcar, podendo interferir no processo de compactação do solo.

Quantifying mineral sources of potassium in agricultural soils [PDF]

open access: yes, 2008
Soil potassium (K) reserves are crucial for crop quality and yield in low input agricultural systems. Soils contain varying amounts of K-bearing minerals and differ in their inherent K supply capacity.

Short-term exposure to biodegradable mulch-film microplastics at field-realistic levels shows no effect on lettuce performance and soil health

open access: yesMicroplastics and Nanoplastics
The increasing use of biodegradable plastic mulch films in agriculture is expected to reduce plastic pollution of soils. Yet, the effects of biodegradable microplastics on plant performance and soil health, under environmentally relevant microplastics ...

Chemical dispersants and pre-treatments to determine clay in soils with different mineralogy

open access: yesRevista Brasileira de Ciência do Solo, 2011
Knowledge of the soil physical properties, including the clay content, is of utmost importance for agriculture. The behavior of apparently similar soils can differ in intrinsic characteristics determined by different formation processes and nature of the

Andisols [PDF]

open access: yes, 2012
Andisols are soils that typically form in loose volcanic ejecta (tephra) such as volcanic ash, cinders, or pumice. They are characterized by andic properties that include physical, chemical, and mineralogical properties that are fundamentally different ...

Metal–Phenolic Complexation Governs Soil Mineral Crystallinity to Enhance Crop Growth

open access: yesAdvanced Science, EarlyView.
A coordination‐driven, coprecipitation approach is presented to obtain polyphenolic‐incorporated minerals with tunable crystallinity, offering insights into how plants may influence soil mineral structures. Soil minerals can incorporate polyphenolic secondary metabolites and enhance plant nutrition by facilitating the formation of amorphous metal ...

Forest soils accumulate microplastics through atmospheric deposition

open access: yesCommunications Earth & Environment
The occurrence and fate of microplastics in forest ecosystems is a recognized knowledge gap. In this paper, we used an aligned extraction method to quantify microplastics (>20 µm) in organic and mineral forest soil horizons and throughfall deposition ...
