Adsorption–Desorption Behaviour of Imidacloprid, Thiamethoxam, and Clothianidin in Different Agricultural Soils

Agriculture
This study evaluated the adsorption and desorption of imidacloprid (IMI), thiamethoxam (THM) and clothianidin (CLO) in an andisol (Freire soil) and an inceptisol (Chufquén soil) from southern Chile with different organic matter and clay contents.

The Effects of Burning Intensity on the Soil C-Related Properties and Mineralogy of Two Contrasting Forest Soils from Chilean National Parks

Fire
Forest fires alter multiple soil properties, from those related to the carbon cycle to mineralogy; however, the responses of various soils to thermal impact remain unclear.

Trichoderma Mobilizes Phosphorus and Cobalt While Excluding Sodium in the Foliar Ionome of High‐Andean Grasses Enriched With Biochar

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This graph shows how guinea pig manure biochar raises the pH in high‐Andean soils (4150 m). Although biochar improves soil quality, nutrient uptake depends on the microorganism: Trichoderma sp. alters the foliar ionome by increasing P and Co and excluding Na, while micronutrients maintain their homeostasis depending on the species. ABSTRACT Acidic high‐

Meningkatkan Efisiensi Pemupukan P Dengan Bahan Organik Pada Andisol [PDF]

, 2000
: Andisol merupakan tanah abu volkan yang mempunyai sifat-sifat khusus terutama kapasitasnya yang sangat besar dalam menjerap P. Jerapan P ini menyebabkan pemupukan P pada tanah ini kurang efisien, sehingga kekahatan fosfat sering menjadi kendala ...

Transformer‐Based Digital Soil Mapping Reveals Land‐Use Legacy Effects on (Sub)Tropical Soil Carbon

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Tropical and subtropical soils store approximately one‐third of global soil organic carbon (SOC) despite covering less than one‐quarter of terrestrial surfaces, yet accurate spatiotemporal prediction methods remain inadequate. We present the first application of transformer architectures to multi‐temporal Landsat observations for SOC ...

An Interpretable Machine Learning Approach to Ecologically Characterize Soil Carbon and Structure From Multi‐Kingdom Microbiome, Texture and Climate

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Soil physical structure is a critical determinant of agricultural landscape resilience, yet standard pedotransfer functions estimate soil hydraulic and structural properties using static abiotic variables, often overlooking the biological mechanisms that actively organize soil structure.

Five decades of hand‐feel soil texture estimation: Accuracy, challenges, and improvements

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soil texture refers to the proportion of fine soil particles with diameters less than 2 mm, classified into particle size categories that define the soil texture class. Hand‐feel estimation in the field is widely used by soil scientists and technicians during pedological surveys to characterize soil horizons.
