Principles of application
Triple super phosphate fertilizer (TSP) is a basal and starter fertilizer.
Basal fertilizer is applied while ploughing or pre-sowing soil tillage in spring and autumn. Application of fertilizer in autumn is more effective, this is explained by its better mixing with soil. During spring application, fertilizer mixing depth with soil reduces to a maximum of 20 cm, which may be acceptable for some cereals, but insufficient for many technical and feed crops.
As the starter, triple super phosphate fertilizer (TSP) is applied in small doses only for stimulation of root system development with low mobile phosphorous in soil.
Side dressing with triple super phosphate is applied with cultivator-fertilizers.
