Section 15.20.10.10 - Soil Testing
A. Except as provided for in §B of this regulation, a professional fertilizer applicator or trained employee shall obtain a soil test prior to any initial application of P2O5 and prior to any second application of nitrogen to a management unit.

(1) The nutrient application is made for the purpose of establishing turf on bare ground; and
(2) The nutrient application is made in accordance with the seeding recommendations of the University of Maryland Extension (Maryland Nutrient Management Manual I-E2, COMAR 15.20.07.02 ):
(a) The land has been disturbed such as by construction or tillage; or
(b) A lawn patch product is used.
C. If a soil test, that is not more than 3 years old, exists for the property, it shall be used to determine the appropriate P2O5 application.
D. Section B of this regulation does not authorize a professional fertilizer applicator or a trained employee to apply fertilizer containing phosphorus to turf when over seeding without basing the application on the results of a soil test.
E. Any subsequent fertilizer applications to the same management unit shall be based on the results of a soil test.
