Most turfgrass managers do not have a strong understanding of turfgrass soils, particularly the biological aspects. Certainly most know that living things, such as worms and insects can reside in soil, but they’re not sure where in the soil they live or what they live on. In fact, it might be safe to assume that most turfgrass managers consider soil to be a mysterious world below the turfgrass ...

Nutrient losses from residential lawns and landscapes can negatively impact water quality. Information about nutrient leaching from established residential landscapes containing a mixture of woody ornamental plants and turfgrass is limited. The objective of our study was to determine the effect of vegetation cover (turfgrass vs. woody ornamental) on nutrient leaching from established landscapes...

Research to date has confirmed 2,4-D residues may dislodge from turfgrass; however, experiments have not been conducted on hybrid bermudagrass (Cynodon dactylon L. x C. transvaalensis), the most common athletic field turfgrass in subtropical climates. More specifically, previous research has not investigated the effect of post-application irrigation on dislodgeable 2,4-D residues from hybrid be...

Three palm species common to southern California landscapes were grown and established under mulch treatments. Turfgrass clippings and Eucalyptus sideroxylon mulches increased the growth of king and queen palms and increased survival of king palms. Although palms growing under fresh eucalyptus mulches did not display nutrient de®ciency symptoms, Mexican fan palm and queen palm were not signi®ca...

Putting green summer stress management is of particular interested in the mid-Atlantic region and other areas in which turfgrass managers must maintain cool-season turfgrass in the area known as the transition-zone. In this region, golf course superintendents must be able to provide acceptable green speeds and turfgrass quality in the heat of the summer when growing conditions are suboptimal fo...

Vegetation is a basic component of urban-suburban environments with significant area coverage. As a major vegetation type in US cities, urban turfgrass provides a range of important ecological services. This study examined the biological carbon fixation of turfgrass in a typical residential neighborhood by linking ground-based measurements, high resolution satellite remote sensing, and ecologic...

Turfgrass soils vary considerably in physical and chemical composition. However, regardless of their properties, most contain a vast array of living organisms, ranging from larger creatures such as earthworms and insects, to microscopic invertebrates, bacteria, fungi, actinomycetes, yeasts, algae and protozoa. All of these organisms affect turfgrass health in important ways. However, perhaps th...

tains more nitrogen than any other element. Fourth, nitrogen is a very dynamic element in the soil system. Its concentration is constantly changing, usually decreasing. The other essential elements are significantly more stable in soils. Nitrogen, therefore, must be routinely added to turfgrass to maintain a soil level sufficient for turfgrass growth. An ideal nitrogen fertilization maintenance...

The effect of returning grass clippings on turfgrass growth and Petrovic (1990) presented an excellent review of the quality has not been thoroughly examined. The objective of this refate of nitrogenous fertilizers applied to turfgrass. Part search was to determine the effects of returning grass clippings in...
