2102 - PLANTS
2100-3 During the planting season, small plan ts and trees, 2 inch caliper or less, may be transplanted “bare-root.”
Exceptions to “bare root” planting are shown in the Contract Documents. When transplanting “bare root,” dig the plant with a root spread ⅓ greater than that required for nursery grown plants of the same type, kind and size.
f.Native or Collected Plants. When collected plants are to be supplied, notify the Engineer not less than 5 days before beginning to dig. Dig only inspected and approved plants. The “bare root” requirements of subsection 2102.2 e . will apply.
g.Anti-Desiccant (Anti-Transpirant). Treat all evergreens or plants in partial or total leaf with an anti- desiccant at the nursery before digging or in the case of potted plants, before de livery. A certificati on of treatment by the nursery or the treating agency is to accompany the treated plants. Treat a ll deciduous plants that break dormancy after delivery but before planting. A pply the polyvinyl chloride complex liqui d by dipping or spraying according to the manufacturer’s recommendation. 2102.3 TEST METHODS None Specified. 2102.4 PREQUALIFICATION None Required. 2102.5 BASIS OF ACCEPTANCE
a.Initial Acceptance. Visual inspection and measurement of plan ts by the Engineer and compliance with all applicable provisions of this Section. Additionally, provide the Engineer with th e certificate of treatment for plants treated with an anti-desiccant.
b.Final Acceptance. Compliance with the “plant establishment” provisions of DIVISION 900. 2103 - SEEDS
2100-4 Section 2103
SEEDS 2103.1 DESCRIPTION This specification covers the ma terial requirements for seeds. 2103.2 REQUIREMENTS
a.General. Provide seeds which comply with the seed and nox ious weed laws of the State of Kansas and applicable Kansas Department of Agriculture Rules and Re gulations except as specifical ly noted in this Section . Do not provide Sericea Lespedeza and Multiflora Rose with any seed.
b.Seed Quality and Definitions. Conduct all seed analyses in accord ance with rules and regulations as prescribed by the Association of Offi cial Seed Analysts (AOSA) and Kansas Seed Law. The Kansas Seed Law specifies the kind and amount of weed seed permitted; the requirement for a current analysis report; and labeling of all seed to show its purity, germination, date of last germination test, and weed seed content. Cleaning and conditioning of seed must result in a pr oduct that meets or exceeds minimum standards. The product must also be clean enough to plant using existing drilling equipment without further processing.
1.Kansas Seed Law. The germination test is valid for 9 months after the end of the month the test was made, so long as the seed remains in Kansas.
2.Federal Seed Law. For seed ship ped across state lines, the germination test is valid for 5 months after the end of the month the test was made.
3.Interpretation of Current Analysis Report. Fo r seed purchased during the valid period of the germination test, the analysis report may be considered cu rrent for the full seeding period in effect at the time of purchase. (If seed is purchased March 1, and the valid date expires March 31, the analysis report may be considered current if the seed is planted by April 30, which is the end of the spring seeding period. If the seed is to be planted during a later seeding season, a new germination test is required.) This interpretation may be amended by the Engineer for those projects in which KDOT delayed seeding to a later seeding season. In these situations the seed need not be retested only for the next season.
c.Pure Live Seed (PLS) Requirements and Determination. Compute percent pure live seed (%PLS) by adding percent germination to percent firm or hard seed. Divide the sum by 100. Multiply this product by the percent purity. % PLS = (% Germ. + % Firm or Hard Seed) x %Purity 1 0 0 Minimum PLS requirements are shown in TABLES 2103-1 and 2103-2. The Engineer may grant permission to use seeds that fail to comply with the required PLS provided the following conditions are met. (1) The Contractor can provide suitable eviden ce to the Engineer that seeds comply with TABLE 2103-1 or 2103-2 are not readily available.
2.The Contractor is willing to increase the quantity of seeds, at no additional cost to KDOT, to provide the minimum quantity of PLS required.
d.Origin of Seed. Where named or numbered strains are not available, use of seed from native stands is permitted if the seed is harvested within ra nge of its planting location not to exceed:
1.300 miles south, 150 miles north or west and 1500 feet in higher elevation.
2.Native seed sources must be identified as to stat e and county where seed was harvested in order to certify location and elevation.
e.Buffalo Grass Seed (Buchloe dactyloides). Buffalo grass seed may be an improved strain, hybrid or named variety as specified on the Contract Documents. Stai n with a dye. Treat all buffalo grass seed to enhance germination. 2103 - SEEDS
2100-5 f. Bulk Seed Determination. Determine the amount of bulk seed needed for each bid item based on PLS
requirements and the following formula: Total Bulk Mass = Bid Item PLS Plan Quantity % PLS 2103.3 TEST METHODS As prescribed by the AOSA and The Kansas Seed Law. 2103.4 PREQUALIFICATION None Required. Seed supplier must follow all regist ration and licensing requirements stated in The Kansas Seed Law. 2103.5 BASIS OF ACCEPTANCE The Engineer will accept each seed shipment to a project work site based on the following:
a.Receipt of a copy of the seed supplier's "Kan sas Seed Law Business Re gistration" certificate.
b.Receipt and approval of a certifica tion from the seed supplier stating the compliance of the supplied seed with this specification and The Kansas Seed Law.
c.Verification that each seed container is labe led as required by The Kansas Seed Law.
d.Verification of compliance with the minimum required % PLS as stated in TABLE 2103-1 and 2103-2.
