Combining UAV Multispectral and Thermal Infrared Data for Maize Growth Parameter Estimation

Agriculture
The leaf area index (LAI) and leaf chlorophyll content (LCC) are key indicators of crop photosynthetic efficiency and nitrogen status. This study explores the integration of UAV-based multispectral (MS) and thermal infrared (TIR) data to improve the ...

Fator de desacoplamento em um canavial irrigado no submédio do Vale do São Francisco Decoupling factor in an irrigated sugarcane crop in the Lower-Middle Sao Francisco

Revista Brasileira de Engenharia Agrícola e Ambiental, 2012
Objetivou-se, com este trabalho, analisar a interação da cana-de-açúcar irrigada com a atmosfera circunvizinha, por meio do fator de desacoplamento (Ω), para cinco períodos distintos de crescimento e entre eventos de irrigação.

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Produtividade do repolho utilizando cobertura morta e diferentes intervalos de irrigação com água moderadamente salina Cabbage yield using mulching and different irrigation intervals with moderately saline water

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
O manejo da irrigação em áreas sob escassez hídrica é imperativo para o incremento da eficiência do uso da água, particularmente em áreas susceptíveis a salinização e a elevadas demandas atmosféricas. Neste estudo avaliou-se o efeito da cobertura morta e

A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

Land Degradation &Development, EarlyView.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.

Integrated export instream coefficient model for accurate nonpoint source pollution estimation and management in the Yellow River Basin

Scientific Reports
The export coefficient model (ECM) remains widely applied in estimating agricultural Non-point Source Pollution (NPSP) due to its simplicity, minimal parameter requirements, and relatively high accuracy.

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

Land Degradation &Development, EarlyView.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...
