There is more to crop nutrition than nitrogen (N) and phosphorus (P).
Crops take up nearly as much potassium (K) as N, and the removal of K in grain can be 30 to 50% more than P.
Sulfur (S) deficiencies in 2021 canola crops also highlighted that good crop nutrition considers all essential plant nutrients.
MacroPro Extra and MacroPro Max supply NPK and S (with copper and zinc) in every granule, reducing the risk of costly nutrient deficiencies. The K is supplied in the sulfate of potash (SoP) form.
Both products have 0.1% copper and 0.2% zinc in every granule.
MacroPro Extra is recommended where crops need as much P as K; MacroPro Max is recommended where the requirement for K is significantly higher than P.
The MacroPro product range has superior handling and application characteristics compared to blends, with a lower risk of uneven nutrient distribution and associated reduced returns.
