<br />Slow-Release Nitrogen
<br />For Dry Application
<br />Nonburning-Nonleaching
<br />Odorless-Pathogenfree
<br />Blue Chip is the granular form of Nitroform® ureaform. Pro-
<br />duced by combining urea and formaldehyde under controlled
<br />manufacturing conditions, its slow-release characteristics are
<br />predictable and dependable. Released by soil microorganisms, the
<br />nitrogen is available during plant growth cycles when organisms
<br />are also most active.
<br />Blue Chip is organic nitrogen only. Nitrogen equivalents are
<br />given below. Supplements of phosphorous, potash, and other
<br />nutrients should be applied as soil tests antl local conditions
<br />indicate. Maintain the soil pH needed for the grass or other plant
<br />being grown.
<br />Nitrogen Equivalents:
<br />1 Ib of Nitroform = 0.38 Ib of nitrogen
<br />2.61bs of Nitroform = 1 Ib of nitrogen
<br />DIRECTIONS FOR USE
<br />Annual nitrogen rate will vary from 2 to 10 pounds (5 to 25
<br />pounds Blue Chip) based on the requirements of different grasses
<br />and geographical areas. Check your turf supplier or the recom-
<br />mendationsfrom your State Extension Service.
<br />TURF AREAS: For normal maintenance on fairways, airfields,
<br />athletic fields, cemeteries, parks, lawns, and similar turf areas, ap-
<br />ply annually 10 to 15 pounds of Blue Chip per 1,000 square feet, or
<br />400 to 600 pounds per acre. Table I gives recommendations for
<br />providing optimum maintenance of turfgrass and lawns.
<br />Split applications are recommendetl, with the heaviest applica•
<br />lion at the time of the most important growth cycle. For cool•
<br />season grasses (bluegrass, fescue, and bent), apply'/, in the fall
<br />and '/, in the spring. For warm-season grasses (bermutla, zoysia,
<br />centipede, and 5t. Augustine), apply al, in the spring and 'Ip in the
<br />fall. For low-maintenance applications that use less than the
<br />10-pound recommended rate, Blue Chip can be applied in a single
<br />application.
<br />For seedbed application, use the recommended annual rate of
<br />Blue Chip, working it into the top 1 to 2 inches of soil.
<br />GREENS AND TEES: For close-knit turf, apply Blue Chip immedi-
<br />ately after aerifying greens and tees, then sweep into holes.
<br />Mower pickup of this granular fertilizer i5 usually very minimal. If
<br />this is a concern, remove mower basket for 1 or 2 cuttings follow-
<br />ing application. Powder BIUeTM, the powder form of Nitroform, can
<br />be sprayed on greens and tees to give more immediate contact
<br />with the soil surface.
<br />FOR SEEDBED APPLICATION: Use 10 pounds of Blue Chip per
<br />1,000 square feet lightly raked into the surface 1 inch of soil.
<br />SOD PRODUCTION: In the seedbed, apply 10 pounds of Blue Chip
<br />per 1,q(10 square feet, or 400 pounds per acre, and work into the
<br />top 1 inch of soil. In established sod, apply 10 pounds per 1,000
<br />square feat, or 400 pounds per acre, in spring or fall, depending on
<br />time remaining till harvest.

<br />TRANSPLANTING SOD: Apply 2'/: to 3 pounds of Blue Chip per

<br />the surface of the sod bed prior to laying the sad.
<br />LAND RECLAMATION PROJECTS: For eatabllehmant only on

<br />Predominantly bluegrass-Apply 10 pounds of Blue Chip per
<br />1,000 square feet, or 400 pounds per acre.
<br />Fescue and native prairie grasses-Apply 8 pounds of Blue
<br />Chip per 1,000 square feet, or 350 pounds p~Br acre.
<br />Grass and legume mixtures-Apply 6 poLlnds of Blue Chip per
<br />1,000 square feet, or 250 pounds per acre.
<br />Blue Chip can be incorporated into the sLlrface 1 inch of soil or
<br />it can be surface-applied by conventional sflreaders, hydro-
<br />seeders, or aerial application.
<br />NURSERY PRODUCTION: Greenhouse, Foliage Crops, and Brrd-
<br />ding Plants
<br />Soil Surtaes-Suggested rate is 'l. pound of Blue Chip for each
<br />inch of plant diameter. For container-ggrown plants, use'/, tea•
<br />spoon per 4-inch pot; 1 teaspoon per Ginch pot. Number of ap-
<br />plications would depend on annual N requirements.
<br />Soil Mix-Mix 2 to 3 ounces of Blue Chip per bushel, or 2 to 4
<br />pounds per cubic yard. For bedding plants, use 2 to 3 pounds per
<br />100 square feet, mixed in top 2 to 3 inches of soil.
<br />ORNAMENTAL, FRUIT AND CITRUS TREES:
<br />Planting Hole-Apply 1 pound of NITROFORM (.381b. N per
<br />gallon-sized container or wrapped ball. Mlx with backilll. For bare
<br />root trees, apply'/, pound of NITROFORM it the planting hole and
<br />mix with backfill.
<br />Surface-Apply'!, pound of NITROFORM for each inch of trunk
<br />diameter. Make application starting from dri ~-line in towards the
<br />trunk.
<br />Consult extension horticulture specialist for timing of nitrogen
<br />applications and recommendetl rates of othErc nutrients.
