Quantifying golf course water use efficiency using three water balance models of varying complexity
Abstract Background Three water balance models were used to quantify water use efficiency on 71 golf courses in the United States. The golf courses were separated into five geographic regions. Methods The United States Golf Association (USGA), Tipping‐Bucket (TB), and Agro‐IBIS (AG) water balance models were used to estimate golf course water ...

Is stimulation of leaf photosynthesis by elevated carbon dioxide concentration maintained in the long term? A test with Lolium perenne grown for 10 years at two nitrogen fertilization levels under Free Air CO2 Enrichment (FACE) [PDF]
Photosynthesis is commonly stimulated in grasslands with experimental increases in atmospheric CO2 concentration ([CO2]), a physiological response that could significantly alter the future carbon cycle if it persists in the long term.. Yet an acclimation

Plant root proliferation in nitrogen-rich patches confers competitive advantage [PDF]
Plants respond to environmental heterogeneity, particularly below ground, where spectacular root proliferations in nutrient-rich patches may occur. Such 'foraging' responses apparently maximize nutrient uptake and are now prominent in plant ecological ...

Glucosinolate hydrolysis products for weed control [PDF]
Glucosinolates are allelochemicals present in all Brassica plants. Upon hydrolysis by endogenous enzymes they produce a series of biologically active compounds, such as isothiocyanates and their deriva-tives among others.

A comparison of four methods for determining pasture botanical composition
The objective of this study was to determine an accurate and efficient method for researchers and/or practitioners to monitor botanical composition. The evaluation methods included visual estimation (top left), occupancy grid (top right), point quadrat (bottom left), and step point (bottom right).

Efficiency of Vegetative Filter Strips in Mitigating Soil Erosion and Surface Runoff
ABSTRACT Vegetative filter strips (VFS) are widely used in agriculture to reduce soil erosion and sediment transport during heavy rainfall events. This study assessed their effectiveness in controlling surface runoff and sediment transport under controlled field conditions.
