13:00:45 is designed for optimal plant nutrition.
Potassium nitrate is a high quality source of both potassium and nitrogen, two essential macronutrients (primary nutrients) for plants.
Since a healthy growth requires large amounts of nitrogen and potassium, these elements have to be applied to the soil regularly.
Total nitrogen (all in Nitrate form) per cent by weight minimum = 13.0% w/w
Water soluble potassium (as K2O) per cent by weight, minimum = 45.0% w/w
