A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Effects of Partner Workload and Increasing Environmental Temperature on Nestling Provisioning and Body Temperature in a Declining Aerial Insectivore

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT With climate change, birds will face increasing thermoregulatory demands, which may alter reproductive behaviors such as offspring provisioning. Experimental studies have shown that the provisioning capacity of female tree swallows (Tachycineta bicolor) is limited by their risk of overheating. Given that parental investment strategies may vary

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

open access: yesJournal 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

Organics Characteristics of Sludge from a Full-Scale Anaerobic Digester Treating Domestic Mixed Sewage Sludge

open access: yesMATEC Web of Conferences, 2017
Sewage sludge, normally in form of mixed sewage sludge is treated using anaerobic digester worldwide. In Malaysia, sewage sludge was categorized as domestic sewage sludge since sewage treatment plant treats only domestic sewage.

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

open access: yesLand 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 ...
