801Lime and Fertilizer

801.1 Description. This work shall consist of the application of agricultural lime and commercial fertilizer and

soil preparation for seeding and sodding on areas shown on the plans or designated by the engineer.

801.2 Material.

801.2.1 Material used for soil neutralization, unless otherwise specified, shall be agricultural lime with no less

than 90 percent passing the No. 8 sieve containing no less than 65 percent calcium carbonate equivalent.

801.2.2 Agricultural lime shall be furnished from a source that has been tested and certified in accordance with

the Missouri Agricultural Liming Materials Act. The quantity of material required to provide the specified pounds of effective neutralizing material (E.N.M.) per acre shall be determined from the producer or distributor's certification of analysis furnished by the Director of the Missouri Agriculture Experiment Station, Columbia, Missouri in accordance with the Missouri Agricultural Liming Materials Act. The contractor shall provide a copy of this certification to the engineer prior to application. If agricultural lime is furnished as a commercially bagged product, pelletized or otherwise, with a guaranteed product analysis shown on the bag listing the elemental properties and gradation, the E.N.M. shall be provided to the engineer. Material may be accepted on the basis of bag label analysis.

801.2.3 Fertilizer shall be a standard commercial product which, when applied at the proper rate, will supply the

quantity of total nitrogen (N), available phosphoric acid (P205) and soluble potash (K20), as specified in the plans or contract. Material may be accepted on the basis of bag label analysis or supplier's certification, and shall be in accordance with all applicable Missouri fertilizer laws.

801.3 Equipment. Lime and commercial fertilizer shall be applied by mechanical equipment designed for this

purpose.

801.4 Construction Requirements.

801.4.1 The area to be limed and fertilized will be the area specified within the limits of construction. The area

shall have a uniform surface free from rills, washes and depressions, and shall conform to the finished grade and cross section shown on the plans. The seedbed shall be prepared by loosening the existing soil on the slope by surface roughening in accordance with the SWPPP or by other mechanical methods approved by the engineer. Adding loose soil is not an acceptable surface preparation method.

801.4.2 Lime and fertilizer shall be applied evenly at the rates specified in the Missouri Standard Plans for

Highway Construction for the applicable region and grass seed mixture type. When a project extends across two regions, the region with the greater acreage of seeding shall be used to determine the lime and fertilizer rates, unless otherwise specificed in the contract. Lime and fertilizer shall be applied separately. Lime and fertilizer shall be applied no more than 48 hours before the seed is sown except when temporary seeding finished areas in accordance with Sec 806.50.2.4.

801.5 Method of Measurement. No measurement will be made for lime or fertilizer.

801.6 Basis of Payment. No direct payment will be made for lime or fertilizer. All costs for liming or fertilizing

shall be included in the applicable seeding item.
