Solution Fertilisers

The OMEX Nitroflo liquid nitrogen plus sulphur fertiliser range can significantly increase yields and improve efficiency in all agricultural settings.
Uptake is via plant roots and this handy guide explains what (and what not) to do to achieve optimum uptake into the plant:

  • Apply
  • When the crop is wet or in the rain
  • In the dry
  • In wind so long as streams are not being deflected
  • Keeping forward speed slow and pressure low
  • In the evening or early morning if possible
  • Plan to complete your applications by GS32 (2nd node on stem detectable) on cereals
  • In sequence: Apply fertiliser first and agrochemicals second. Leave a 2 day gap if possible
  • Keep grazing stock out for 5 days if there has been no rain
  • Avoid
  • When the crop is just damp and drying off – this may lead to a smear of nitrogen drying on the leaf, leading to too much leaf uptake
  • In wind once feathers of small droplets are being blown from the main stream, or if the wind has caused leaf bruising
  • Going above 2 bar pressure unless you really have to
  • In the heat of the day or when >20°C between max and min is expected
  • Don’t apply to the flag leaf (or leaf 2 if possible)
  • In sequence; Don’t apply agrochemicals first – they are likely to de-wax the leaves and increase to risk of foliar uptake of N. Leave a 5 day if possible
  • Don’t dilute liquid nitrogen, it increases the risk of scorch
  • Avoid application onto damp crops or after a hard frost

Basic conditions guide:

This handy guide gives you a quick glance on what to do in certain conditions. Always ensure you follow up to date application protocol.

Situation Application okay Wait
Wet leaf If wet to the point of runoff If leaf is just damp (no droplets); wait until dry
Rain If forecast to continue If light and water not rolling off
Frost If heavy rime, on cereals only Wait a few days for crop to rewax and until leaf is dry
Wind If streams not badly affected If stream breaking up excessively
Agchem Before agchem A few days if agchem has been applied
