Fertiliser calculators

A useful collection of calculators to compare the return on investment and margin over fertiliser when using different fertilisers.

Nitrate vs Urea NS vs Straight N Compound vs Blend CN vs CAN Wheat N Response Value of Grass

The value of grass

The value of grass as a livestock feed is often undervalued.  This calculator uses the costs of alternative standard bought-in feeds to calculate the value of the grass as a feed and also calculates the cost of nitrogen fertiliser to grow the grass as a proportion of the value of the grass.

The calculations of grass value are based on the comparative costs of 'standard' feeds using 'book values' for dry matter, protein content and energy values, based on the AHDB Dairy 'relative feed values calculator'.

Recommended fertilisers

The following grassland fertilisers are recommended

YaraBela NUTRI BOOSTER
25% N + 2% S, Na and Se - Unique compound fertiliser for use on grass, based on CAN offers farmers the option of applying nitrogen and sulphur coupled with sodium and selenium in the form of sodium selenate.
YaraMila SUPER BOOSTER
25-2.2-4.2 + 2%S + Na and Se - Compound prilled NPKS fertiliser with sodium selenate for use on grassland to supplement selenium levels.
YaraBela AXAN
27% N + 3.6% S - Uniform compound granular nitrogen and sulphur fertiliser for use on all crops.
YaraMila EXTRAGRASS
27-2.2-4.2 + 2.4% S - Compound granular NPKS fertiliser ideally suited to little and often application for Spring/Summer application to grassland for index maintenance and high recovery growth rates.
YaraMila GREEN SWARD
27-2.5-5 - A compound fertiliser ideal for intensive grass growing systems. Ideal where not too much phosphate and potash is required and natural sulphur supply is sufficient.
