Overview
About this product
Proventus Ultra P — a balanced water-soluble NPK 13-40-13 + ME fertilizer with a high phosphorus content, micronutrients and biologically active substances from the PROVENTUS line of dry powdered fertilizers. The maker advises it for all crops in the initial growth period, which for some crops lasts from germination to budding or flowering, and links the raised phosphorus content to root system growth.
Nitrogen 13: nitrate 3.7, ammonium 9.3; P₂O₅ 40, K₂O 13, without units. If the substrate is charged with basal fertilizer, it can be applied without other fertigants, otherwise together with other water-soluble fertilizers.
Fertigation 5–15 kg/ha per day.
Application
Rate, timing and crops
- Timing
Initial period of growth and development; for some crops from germination to budding or flowering
- Method
Fertigation: 0.5–1.5 kg per 1000 m² per day (5–15 kg/ha per day) through any fertigation and irrigation systems; if not daily, the rate is increased in proportion to the number of days between feedings (for example, 5–15 kg per 1000 m² every 10 days)
Drip irrigation: concentration in the working solution 0.1–0.15% (1.0–1.5 kg/m³)
- Conditions
Optimal air temperature 10–25 °C, wind up to 5 m/s
If the substrate (soil, soil mix, coconut substrate, peat, expanded clay) is charged with basal fertilizer, it can be applied without mixing with other fertigants; otherwise together with other water-soluble fertilizers
- Tank mix
Well compatible with most pesticides and fertilizers, except non-chelated calcium-containing ones
