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.
Oat growth and development
The oat crop goes through three distinct phases as it grows from planting to harvest. These phases can be described as foundation, construction and production.
