Oat nutrient requirements

Oat nutrient requirements vary depending on the crop growth stage. Find out which nutrients are most important at different growth stages.

Roles of nutrients at different growth stages

Establishment

Nitrogen for early rapid growth.
Phosphate to supply the energy for early growth and development, especially root mass.
Manganese for its role in the structure of photosynthetic proteins and enzymes. 
Zinc for enzyme reactions, early growth and vigour.

Tillering

Nitrogen for leaf development and size, increasing tiller number per plant.
Manganese for its role in the structure of photosynthetic proteins and enzymes.

Stem Extension

Nitrogen for large leaves, rapid growth and development.
Phosphate to supply the energy for growth and development.
Potassium for plant water regulation and structural integrity.
Sulphur for yield and quality improvements.
Manganese for its role in the structure of photosynthetic proteins and enzymes.
Zinc for enzyme reactions, nitrogen metabolism, and protein synthesis
Copper for enzyme activity, chlorophyll production and seed production.

Flag Leaf and Grain Filling

Nitrogen for higher yields through green leaf duration, grain site survival, grain size and protein levels.
Magnesium for green leaf duration.
Phosphate for dry matter remobilisation for yield improvements.
Boron for pollen viability
Zinc for grain protein.

The agronomic principals behind oat production are to first build an efficient leaf canopy and then keep this photosynthetically active right through to harvest. An effective crop nutrition programme can help achieve both of these objectives.

Agronomy Advice - Do you really need straight nitrogen
Do you really need straight nitrogen
Before ordering your straight nitrogen it is worth considering how much you actually need as it may be you actually need NS or NPKS grades instead.
Agronomy Advice - Don't forget about sulphur
Don't forget about sulphur
Sulphur was often overlooked in the past but today it is recognised as an essential nutrient and considered just as important as nitrogen, so not to be forgotten.
Heavier fertiliser spreads further
Heavier fertiliser spreads further
Some fertilisers consistently spread further and more accurately than others. A heavier and larger fertiliser granule will spread further because the spreader can put more energy into it.
