Crop Details

Yield and Quality

Increases from using Calcium Nitrate rather than Ammonium Nitrate as a top dressing.


Over the years Tropicote has shown consistent increases in overall yields of up to 10% on potatoes and up to 6% on brassicas


Typically growers using Tropicote find the increase in quality results in a higher percentage of Grade One produce.

Recommended calcium nitrate fertilisers

The following YaraLiva calcium nitrate fertilisers are recommended and contain readily available calcium and nitrogen and Boron too in the case of Nitrabor.

YaraLiva TROPICOTE
15.5% N + 26.3% CaO - Granular calcium nitrate fertiliser for field application to a wide range of crops.
YaraLiva NITRABOR
15.4% N + 25.6% CaO + 0.3% B - Granular calcium nitrate fertiliser with added boron suitable for field application to all crops especially brassicas which are more prone to calcium and boron deficiency.

Fertiliser quality - don't settle for less
Soil fertility is certainly top of both farmers and policy makers minds currently, with a broad consensus that it plays a key role in the continued economic and environmental sustainability of farms.

Keeping clover in fine fettle
White clover is being increasingly used on intensively grazed farms where the benefits can be substantial, lowering both the cost of growing grass and the carbon emissions intensity of milk produced. Managing nutrient and fertiliser inputs is a key component in establishing and maintaining clover in these swards successfully.

Sulphur: Best Practice
It is widely accepted that UK soils are deficient in sulphur so supplementation via organic manures or mineral fertilisers is essential. What I think is less understood is that not all sulphur-containing fertilisers are the same.
