Sussex Conservation District (SCD) is now offering free pre-sidedress soil nitrogen testing (PSNT) to corn growers in Sussex County. SCD recommends performing a PSNT in the spring to determine the nitrogen requirements of an expected corn crop yield. Fields that have received applications of animal manure are ideally suited for PSNT.

 PSNT measures the amount of available nitrogen in the soil to determine if additional fertilizer nitrogen is needed. The test also eliminates the uncertainty associated with utilizing manure nitrogen. A limited number of tests are available. Call 302-856-3990, ext. 3, or email Dan Holston at, to schedule your PSNT when plants reach four to six inches in height or growth stage V2.
