Micronutrition for UK Crops

Micronutrition for UK Crops

 

Micronutrients are required by crops in relatively small quantities, but shortages can still restrict growth, development, quality and yield.

The availability of individual nutrients varies with crop, soil, pH, rooting, weather and stage of development. A nutrient may be present in the soil but not always available to the crop when demand is highest.

Agrii combines crop observation, soil and tissue analysis with targeted micronutrient products to help identify where intervention is justified and select the right nutrient, rate and timing.

Where micronutrition fits

Micronutrition should start with crop requirement rather than the product.

Deficiencies may develop where soil availability is naturally low, root activity is restricted or crop demand exceeds the supply available at a particular growth stage.

Foliar applications can provide a targeted way of supplying specific nutrients where there is a clear requirement, particularly where soil uptake is restricted.

 

Identifying crop nutrient requirements

Visible symptoms can provide useful clues, but by the time a deficiency becomes obvious, crop performance may already have been affected.

Soil analysis, tissue testing and crop monitoring can help identify nutrient limitations earlier and support more targeted decisions.

Interpretation is important because similar symptoms can have several causes, including root restriction, pH, waterlogging, drought or interactions between nutrients.

 

Targeted nutrition through the season

Crop demand changes as the season develops, so micronutrient applications should be positioned around crop requirement, growth stage and the likelihood of a response.

Where root uptake is restricted, foliar nutrition may have a role in supplying specific nutrients, but it should complement rather than replace the wider crop nutrition programme.

Your Agrii agronomist can help interpret analysis results and identify where targeted micronutrition may add value.
