9VAC25-32-470. Crop monitoring and reporting.
Vegetation monitoring may be required by the board upon recommendation of the department once every three years on sites with frequent applications of biosolids applied at or greater than agronomic rates and when 400 pounds per acre or more of available phosphorus has been applied to the soil. Analyses of plant tissue should be conducted at the proper growth stage as recommended by either the Virginia Department of Agriculture and Consumer Services, the Virginia Department of Conservation and Recreation or Virginia Cooperative Extension Service. Routine analyses include nitrate-nitrogen, phosphorus, potassium, calcium, manganese, magnesium, iron, copper and zinc. Analysis for additional parameters may be necessary as determined on a case-by-case basis. Results shall be reported annually to the department.
