Crops remove more potassium (K) than phosphorus (P), so it is essential to recommend adequate levels of K especially if it is the more limiting nutrient.
The growing need for K (relative to P), has led to CSBP developing K-Till Max, a new NPK compound with higher levels of potassium incorporated into every granule.
The analysis of K-Till Max is 9.6 N, 9.4 P, 15.0 K, 6.5 S, 0.12 Cu, and 0.24 Zn. It is a fully compounded fertiliser manufactured in our granulation plant at Kwinana.
The ratio of P to K in K-Till Max matches the amount of these nutrients that is removed in the grain at harvest.
A tonne of wheat removes approximately 3 kg of P and 5 kg of K, so a 3 t/ha crop removes about 9 kg of P and 15 kg of K. This is the amount of nutrients supplied by 100 kg/ha of K-Till Max. The sulphur supplied by K-Till Max also matches the removal rate in cereals (removal rates are higher in canola).
CSBP trials around the state have demonstrated the value of using K-Till Max. Feedback from Growers using trial product has also been positive.
K-Till Max is the ideal seeding fertiliser where maintenance amounts of P, K and sulphur are required.
CSBP’s K-Till range is Western Australia’s leading fertiliser compound at seeding. See the analysis and find out more about the K-Till range.
