Potatoes - Meeting nutrition demands

Potato nutrition demand

Potatoes are not unique in this respect, but virtually all of their macro-nutrients applications are made before the crop is planted and well before the peak uptake of nutrients that happens 60-75 days after emergence. This, coupled with the plant's naturally poor inherent ability for rooting, means that efficient uptake of nutrients is always challenging.

What are the nutrition implications following the autumn/winter rainfall?

Flooded-soil

Well, it won't be surprising to learn that many soils will have lost nitrogen via leaching.

To demonstrate the impact, AHDB has produced a map to show the winter rainfall classification. This forms part of the RB209 book method for producing a Soil Nitrogen Supply (SNS) index and is a good starting point as you begin to look at your nitrogen programme for this spring. 

However, rather than rely solely on this information, our team at Frontier decided to carry out the measurement of Soil Mineral Nitrogen (kg N/ha) at a number of nationwide trial sites. The findings are outlined in the below table.

Do you have a phosphorus problem?

SOYL-Frontier-Agricultural-4267
In the UK, we don't have a domestic supply of artificial phosphorous fertiliser and so are therefore reliant on imported sources of nutrient phosphorus. Part of this means that we often experience some volatility in pricing, usually influenced by fluctuations in currency, available volume, country of origin and – more recently – political developme...

Maximizing grassland production

grass
Much of the grass in Herefordshire, where I am based, suffered during the difficult weather conditions of 2018 and consequently producers should focus on optimising nutrition to restore both quality and yield potential to former levels, with K and S being essential in this process. This season NKS fertilisers containing potash and sulphur alongside...
