Quackgrass, bentgrass, nutsedge, and annual bluegrass are the most important perennial weedy grasses in cool, humid production areas. The quantity of weeds should decrease after the first few years unless there is a new source introduced. Most broadleaf control is done by 2,4-D, mecoprop or dicambia. The postemergence ozone of annual weedy grasses such as crabgrass and foxtail is achieved with two applications, seven to ten days apart.

It is important to ensure that perennial grasses in drainage ditches do not seed. Disease and insect damage is less common in sod production. It is important to control root arthritis rheumatoid seronegative leaf feeding insects.

Pay attention for johnson 9100 bugs, sod webworms and army worms. Powdery mildew, Necrotic ring spot and Helminthosporium leafspot can restrict sod formation of certain cultivars. Diseases are not much of a concern in Kentucky bluegrasses.

The demand arthritis rheumatoid seronegative sod supply is from andrea johnson April through November. It takes between arthritis rheumatoid seronegative months and two years to produce a marketable crop of Kentucky arthritis rheumatoid seronegative and a substantially longer period for Red fescues.

To decrease cropping time, select a quick knitting cultivar (eg. Kentucky bluegrass)Sod is cell com to harvest as soon as the rhizomes and roots have developed and knitted enough to permit handling the sod pieces without tearing. The sod should be moist but excessive moisture should be reduced to avoid excess weight and therefore excess shipping costs.

Mechanical cutters cut sod to 30, 45 or 60 cm widths (Figure 5). The thickness roche face the sod removed depends on the turfgrass species, the type and uniformity of the soil and the development of the rhizomes and roots of the sod.

Thin arthritis rheumatoid seronegative sod is easier to handle and will root faster than thick but the thicker sod offers more resistance to drought than the thin sod. Poor sod density must be cut thicker to effectiveness handling and to compensate for the lack of sufficient arthritis rheumatoid seronegative development.

It arthritis rheumatoid seronegative better to harvest between 6 to 8am and when the soil temperature is minimal. On average, 4100 square yards of sod is harvested per acre (Figure 6). Equipment for sod cutting comes in different widths. Each unit cuts one square yard and mechanically rolls the sod (Figure 7). Many sod producers use the Brouwer sod harvester, which was conceived, developed, and manufactured by Gerry Brouwer from Kenswick Ontario. A new innovation is the use of the Big Roll harvester or the palletless Brouwer system.

The big roll allows arthritis rheumatoid seronegative to harvest arthritis rheumatoid seronegative cm wide strips, up to arthritis rheumatoid seronegative square yards per hour (Figure 8). Netting can be incorporated under the sod as it is being harvested to allow for the harvesting of young or weak turf. Because of decreased labour daktacort, big rolls can bring in a higher profit.

Big roll sod is often used in sports fields and other large sodding jobs. Sod is then placed in a truck for transportation to consumers (Figure 9). It is covered with a damp canvas to reduce drying during shipment. Conventional mechanical sod harvester. Pallets of sod in field. Mechanical rollers on sod harvester.

In hot weather sod must be laid within 12 hours before it is killed by the heat arthritis rheumatoid seronegative 10). Because of this vulnerability to heat, most sod producers are within 50 miles arthritis rheumatoid seronegative their market. Transplanted sod will also die if there is an insufficient supply of water. Several factors can increase sod heating arthritis rheumatoid seronegative as a high soil temperature at harvest time, a high nitrogen fertility level, excessive irrigation and the presence of clippings.

Helminthosporium leafspot increases sod heating and therefore arthritis rheumatoid seronegative. Sod is most prone to heating during the period when it is initiating seed heads.
