Recent evidence might cast the nitrate problem in a somewhat different light and may offer a few solutions.More>>

Wear and soil compaction are the major cause for turfgrass stress under intense traffic typical of golf courses and athletic field turf. That traffic can be broken down into two separate stresses, wear and soil compaction (Carrow and Petrovic, 1992).More>>

Increasingly, products containing humic substances are appearing in the turf industry market claiming to reduce water and fertilizer use by increasing soil moisture and nutrient availability. Humic acid is the most common humic substance that has been studied, but results have been highly variable...More>>

Several years of research at Virginia Tech indicate that improving certain rootzone environment conditions, particularly overcoming water repellency and providing consistent water availability, enhanced turf ability to avoid drought stress resulting in more efficient photosynthesis and greater...More>>

Soil composition: The researchers studied warm-season turfgrasses to determine the existence of genetic differences in aluminum tolerance.More>>

A Canadian study of the effects of core aeration finds that the proper timing of aeration may make a difference to drainage through the rootzone mix. The research also suggested ways to reduce the chance of developing a compaction pan.More>>

The authors report on their research into optimal annual bluegrass sod production techniques conducted at California Polytechnic State University between 2001 and 2004.More>>

A study of 50 New Zealand golf courses tested a method of assessing turf uniformity parameters. The study allowed the New Zealand Sports Turf Institute to develop a technique to measure turfgrass uniformity and a database that helps them advise superintendents.More>>
