629.1Description

(1)This section describes furnis hing and incorporating fertilizin g material in the soil on areas of proposed

seeding or proposed sodding.

(2)This section also describes fu rnishing and incorporating agricultural limestone in the soil.

629.2Materials

629.2.1 Fertilizers 629.2.1.1 General

(1)Use fertilizers for seeding, sodding, or other planting that a re standard commercial packaged or bulk

products in granular or liquid fo rm conforming to Wisconsin sta tutes and the Wisconsin administrative code chapter ATCP 40. Ensure that each container of packaged fe rtilizer is plainly marked with the analysis of the contents showing m inimum percentages of total n itrogen, available phosphoric acid, and soluble potash. If furnishing the fertilizer in bulk, include an invoice in each shipment indicating the minimum percentages of total nitrogen, available phosphoric aci d, and soluble potash in the contents. http://docs.legis.wi.gov /statutes/statutes/ http://docs.legis.wi.gov/code/ admin_code/atcp/020/40.pdf

(2)If using fertilizer with a total of nitrogen, phosphoric acid, and potash greater than 32 percent for type A

or 50 percent for type B, apply t hem at a rate that provides eq ual nitrogen, phosphoric acid, and potash. 629.2.1.2 Type A

(1)Type A fertilizer shall conform to the following minimum requi rements:

Nitrogen, not l ess than ....................................... ............................................................... ............................. 16% Phosphoric Acid, not less than ................................ ............................................................... ......................... 6% Potash, not l ess than ......................................... ............................................................... ............................... 6%

(2)The total of nitrogen, phosphoric acid, and potash shall equal at least 32 percent.

(3)Total nitrogen shall at lea st equal the sum of the phosphoric acid and soluble potash.

629.2.1.3 Type B

(1)Type B fertilizer shall conform to the following minimum requi rements:

(2)The total of nitrogen, phosphoric acid, and potash shall equal at least 50 percent.

629.2.2 Agricultural Limestone

(1)Conform to chapter 94.66 of the Wisconsin statutes and of the Wisconsin administrative code chapter

ATCP 41. Furnish limestone with a neutralizing index of not less than 40 or more than 109. http://docs.legis.wi.gov /statutes/statutes/94 http://docs.legis.wi.gov/code/ admin_code/atcp/020/41.pdf

(2)Before using, furnish a statem ent to the engineer indicating t he index zone or grade of the limestone

for each deposit.

629.3Construction

629.3.1 Fertilizer 629.3.1.1 General

(1)Uniformly apply the fertilizers elected for the seeding areas and incorporate into the soil by light

discing or harrowing. If applying granular fertilizer, ensure i t is well pulverized and free from lumps.

(2)If incorporating fertilizer int o topsoiled areas, the contract or may apply it just before, and in conjunction

with, final discing or harrowing, o r if hand manipulating the t opsoil, apply it just before final raking and leveling.

(3)If placing fertilizer on surfaces with no topsoil, prepare the soil by discing or har rowing to at least 6

inches deep and then incorporate the fertilizer as specified ab ove.

(4)If sowing seeding areas by pressure sprayer, then fertilize by placing the required quantity of fertilizer

in the tank, mixing with the water and the seed, agitating constantly, and apply during the seeding operation. If applying fertilizer th is way then the department will not require discing and harrowing after placement.

Effective with the December 2018 Letting 392 2019 Standard Spec ifications (5) If fertilizing areas to receives od, spread the fertilizer uniformly over the soil before sodding at the rate specified below, and then work the fertilizer into the soil while preparing as specified for preparing the earth bed in 631.3.1 .

(6)If applying fertilizer for work specified under 632, then apply the fertilizer as specified in that section.

629.3.1.2 Type A

(1)Apply fertilizer containing 32 percent total of nitrogen, phos phoric acid, and potash at 7 pounds per

1000 square feet, unless the contract specifies otherwise. For type A fertilizer that c ontains a different percentage of components, determi ne the new application rate by multiplying the specified rate by a dimensionless conversion factor determined as follows: Conversion Factor = 32 / New Percentage of Components 629.3.1.3 Type B

(1)Apply fertilizer containing 50 percent total of nitrogen, phos phoric acid, and potash at 7 pounds per

1000 square feet, unless the contract specifies otherwise. For type B fertilizer that c ontains a different percentage of components, determi ne the new application rate by multiplying the specified rate by a dimensionless conversion factor determined as follows: Conversion Factor = 50 / New Percentage of Components 629.3.2 Agricultural Limestone Treatment

(1)Unless the contract specifies o therwise, spread agricultural l imestone over the contract-designated

areas at a uniform rate, measured in pounds per 1000 square fee t, as follows: INDEX ZONES 40-49 50-59 60- 69 70-79 80-89 90-99 100-109 RATE 140 120 100 90 80 70 60

(2)To conveniently check the requi red application rate, the contr actor may measure materials used on a

volumetric basis, providing the conversion from weight to volume is determined from representative samples of materials used.

(3)Incorporate the agricultural limestone with the required ferti lizers into the soils in the designated areas.

The construction requirements applicable to fertilizers shall a pply to those materials also.

629.4Measurement

(1)The department will measure the Fertilizer bid items by the hundred pounds (CWT) acceptably

completed, measured based on an application rate of 7 pounds pe r 1000 square feet. The department will not measure fertilizer us ed for the bid items under 632 . The measured quantity equals the number of hundred-weight (CWT) of materia l determined by multiplying t he actual number of cwt. of material incorporated by the ratio of t he actual percentage of fertilize r components used to 32 percent for type A and to 50 percent for Type B.

(2)The department will measure Agri cultural Limestone Treatment by the ton acceptably completed,

measured based on an application rate of 100 pounds per 1000 sq uare feet and an index zone of 60- 69. The measured quantity equals the number of tons of material determined by multiplying the actual number of tons of material inco rporated by 100 and dividing by the application rate required for the index zone of the material used.

629.5Payment

(1)The department will pay for measured quantities at the contrac t unit price under the following bid

items: ITEM NUMBER DESCRIPTION UNIT

629.0200 - 0299 Fertilizer (type) CWT

629.1100 Agricultural Limestone Treatment TON

(2)Payment for the Fertilizer bid items is full compensation for providing, hauling, placing, and

incorporating in the work.

(3)Payment for Agricultural Limesto ne Treatment is full compensation for furnishing, hauling, placing, and

incorporating the required materials in the soil.
