A Survey of Professional Turfgrass Managers in Southern California Concerning Their Use of Turfgrass Best Management Practices

California Turfgrass Culture

Wetting agents can be used to increase infiltration rates into hydrophobic (water repellent) soils. A field test was conducted on a soil classified as Tujunga stony sandy loam, which was found to be extremely hydrophobic to learn more about the effectiveness of wetting agents. The area is located near Fontana. The land had been farmed in small grain crops years ago and then was used as a hog ra...

Utilizing Iron In Turfgrass Management

D r. George Wallace a researcher from UCLA, writing in HortScience called the 1980s the decade for advancement in our knowledge of iron (Fe) and plant nutrition. He states: "More progress was perhaps made in the 1980s on understanding and management of Fe chlorosis in plants than during the previous 150 years since it became known that Fe deficiency was involved in the chlorosis." Iron is used ...

Principles and History of Turfgrass Pest Management

Assessment of a turfgrass sod best management practice on water quality in a suburban watershed.

The disposal of manure on agricultural land has caused water quality concerns in many rural watersheds, sometimes requiring state environmental agencies to conduct total maximum daily load (TMDL) assessments of stream nutrients, such as nitrogen (N) and phosphorus (P). A best management practice (BMP) has been developed in response to a TMDL that mandates a 50% reduction of annual P load to the...

Nematicide treatments of turfgrass seed.

Seed treatments of improved Kentucky bluegrass and fescue cultivars with carbofuran, oxamyl, and phenamiphos dissolved in acetone reduced seedling emergence, but treatments were not extremely phytotoxic. Phenamiphos was the most toxic, particularly at the 5,000 mug/ml concentration. Fresh weight of grass clippings 35 d following planting generally was greater in treatments than in controls exce...
