Nitrates
I had posted this in the discuss forum, but didn't get much results, can you help??
What does the Nitrate-N ppm level mean on a soil test? Mine is way up from last year. Is this a residue from last season or is this actually Nitrogen? Do I still use a nitrogen source this year? CECIL ------------- SOIL TEST SPRING 2008 Performed by Penn State University-$9 Soil PH 7.0 Optimum Phosphate 1040 lb/A Above Optimum Exchangeable Cations (meq/100g) Acidity 0.0 Potash 0.9 Magnesium 2.3 Calicium 22.8 CEC (Cation Exchange Capacity) 18.2 % Saturation of the CEC Potash 4.8 Optimum Magnesium 12.8 Above Optimum Calcium 82.4 Above Optimum Optional Tests-additional fee Organic Matter-18.2% Nitrate-N ppm 104.4 Ammonium Nitrogen mg/kg 6.45 (electrode method) Soluable Salts-mmhos/cm 0.09
