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

Land 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.

Suction variations and soil fabric of swelling compacted soils

Journal of Rock Mechanics and Geotechnical Engineering, 2010
AbstractThis study addresses firstly the soil fabric variations of loose and dense compacted soil samples during a single wetting/drying cycle at suctions between 0 and 287.9MPa using mainly the mercury intrusion porosimetry (MIP) tests. Two suction techniques were employed to apply this wide suction range: the osmotic technique for suctions less than ...

Suitability of slightly saline irrigation for alleviating drought stress in taro and yam in Tonga: Implications for climate‐resilient Pacific cropping systems

PLANTS, PEOPLE, PLANET, EarlyView.
There is an increasing risk of drought and salinisation of soil and groundwater globally, including in Pacific Island countries such as Tonga. Irrigating crops with slightly saline water, such as that produced by emerging desalination technologies, could help to alleviate droughts.

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

Pest Management Science, EarlyView.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies

Pest Management Science, EarlyView.
Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Centrifuge tests on a soil plug removal method for suction caisson during installation

Applied Ocean Research
The suction caisson is one of the most widely adopted foundation systems for supporting offshore wind turbines and anchoring floating platforms. During suction-assisted installation, the soil inside the caisson may heave and form a soil plug that ...

Influences of Internal Wave Current on Stability of Wellhead Suction Module

Shiyou jixie, 2023
In order to study the influences of internal wave current on the stability of the wellhead suction module, an analysis model of wellhead suction module was established.The p-y curve method was used to perform the spring equivalent simulation of soil ...

Managing pests by increasing predators through late termination of cover crops

Pest Management Science, EarlyView.
Adding cover crops to crop rotations can improve the sustainability and ecosystem functioning of agroecosystems. By delaying cover‐crop termination, growers can effectively increase natural enemy populations and reduce the need for chemical controls. Abstract BACKGROUND Adding cover crops to crop rotations can improve the sustainability and ecosystem ...

Suction cup system‐dependent variable boundary condition: Transient water flow and multicomponent solute transport

Vadose Zone Journal, 2020
Suction cups are widely used in agricultural and environmental research and monitoring under the hypothesis that the sample chemistry represents the soil pore water solute composition around the cup location.
