Deep Core Nitrogen

from £86 per sample


Soil Mineral Nitrogen (SMN) sampling is appropriate where the soil nitrogen supply is likely to be large and uncertain. Direct measurement will result in the best assessment of the amount of soil nitrogen available for a a crop and lead to a more accurate decision about how much additional nitrogen to apply.


This service includes sampling, analysis and reporting of dry matter, Nitrate-Nitrogen, Ammonium-Nitrogen and Total Available Nitrogen in the soil profile.


Why sample for Deep Core Soil Mineral Nitrogen?


  • Obtain a reliable estimate of the soil nitrogen supply to optimise nitrogen fertiliser doses.


  • It usually has a bigger effect on crop growth, yields and quality than any other nutrient.


  • Nitrogen can be lost by leaching, ammonia volatilisation and denitrification.
