Irrigation and Drainage, EarlyView.ABSTRACT Irrigation can strongly influence agricultural productivity and sustainability. While sensor‐based irrigation has the potential to improve yield, reduce input costs and enhance resource‐use efficiency, its adoption in commercial agriculture remains limited.

Conventional and organic cropping systems at Suitia IV: weeds
Agricultural and Food Science, 1990 At Suitia, Southern Finland, weed populations in different crop rotations at conventional and organic cropping systems were investigated in 1982—1988. The number of weeds and the dry matter yields of weeds were greater in organic cropping (on average 324

Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract Greenhouse gas emissions from crop production contribute to anthropogenic climate change, while agricultural soils also sequester atmospheric carbon. Direct measurement of soil organic carbon (SOC) is limited by high sampling costs and the vast spatial extent of farmland.

Journal of Applied Toxicology, EarlyView.ABSTRACT Monocrotaline (MCT), a plant‐derived pyrrolizidine alkaloid, is well known for its hepatotoxic effects. However, full elucidation of the mechanisms underlying MCT‐induced hepatotoxicity, as well as the development of reliable biomarkers for early detection and monitoring, requires an integrated evaluation of biochemical, molecular, and ...

Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...
