Soil Nitrogen Supply (SNS) calculator

The Soil Nitrogen Supply (SNS) Index is an indicator of the soils capacity to supply N to a crop in the absence of applied fertilisers. The more N the soil can supply, the less fertiliser N needs to be applied. The calculatoris used to obtain the number required when using the AHDB Nutrient Management Guide (RB209), to get guidance on fertiliser application rates.

The calculator is available to download from the Agricultural Industries Confederation, (AIC), website by clicking here. The AIC is one of the founding partners of Tried & Tested and provides substantial support to our activities. The promotion of Tried & Tested on the AIC website can be found here.

The calculator is also available on the Tried & Tested USB memory stick.
