Opportunities for improving irrigation efficiency with quantitative models, soil water sensors and wireless technology [PDF]

Increasingly serious shortages of water make it imperative to improve the efficiency of irrigation in agriculture, horticulture and in the maintenance of urban landscapes.

Do topical repellents divert mosquitoes within a community? Health equity implications of topical repellents as a mosquito bite prevention tool. [PDF]

, 2013
OBJECTIVES: Repellents do not kill mosquitoes--they simply reduce human-vector contact. Thus it is possible that individuals who do not use repellents but dwell close to repellent users experience more bites than otherwise.

Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

Entomologia Experimentalis et Applicata, EarlyView.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

Quantifying surfactant interaction effects on soil moisture and turf quality [PDF]

, 2009
Soil water repellency occurs widely in horticultural and agricultural soils when very dry. The gradual accumulation and breakdown of surface organic matter over time produces wax-like organic acids, which coat soil particles preventing uniform entry of ...

Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Sediment Management for Southern California Mountians, Coastal Plains and Shoreline. Part D: Special Inland Studies [PDF]

, 1982
In southern California the natural environmental system involves the continual relocation of sedimentary materials. Particles are eroded from inland areas where there is sufficient relief and, precipitation.

Soil wettability can be explained by the chemical composition of particle interfaces-An XPS study [PDF]

, 2017
Soil wettability (quantified in terms of contact angle, CA) is crucial for physical, chemical, and biological soil functioning. As the CA is determined by components present within the outmost nanometer of particles, this study applied X-ray ...

Modelling of water infiltration into water repellent soils

, 2022
Abstract. Infiltration into water repellent soils has been widely observed, quantified and documented. The modelling of water infiltration into water repellent soils is more rarely taken into account explicitly. In this study, we modelled water infiltration into water repellent soils considering explicitly the contact angle, with the geometrical pore ...

The Ambiguous Ecologies of Agri‐Alternatives: Exploring the Calculus of Social Reproduction in Rural India

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper advances scholarship on agri‐alternatives by probing the gap between romanticised narratives of how alternative farming transitions ought to be and the actual practices farmers enact in their fields. Focusing on moments when such alternatives encounter on‐the‐ground realities, we propose ambiguous ecologies as a lens to explore the ...

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.
