AgriPLUS™ Potassium Nitrate 13-00-45

AgriPLUS™13-00-45 is a fully water-soluble Potassium Nitrate 13-00-45 fertilizer, a highly efficient source of potash and nitrogen for plants. AgriPLUS™13-00-45 is recommended for use at the fruit development stage of growing season, because potash availability is crucial for the development of fruits at this stage. AgriPLUS™13-00-45 can serve as a high quality source of potash, also during other stages of the growth cycle where plants requirement of potash is high.


Its high purity and water-solubility make AgriPLUS™13-00-45 an ideal fertilizer for nutrigation and for foliar nutrition. AgriPLUS™13-00-45 is suitable for preparation of fertilizer blends and production of liquid fertilizers also.

Double benefit: AgriPLUS™13-00-45 is not only an efficient source of potassium, but also facilitates plant uptake of the Ca & Mg present in the soil. This is due to the synergistic effect of negatively charged (anion) nitrate nitrogen (NO3-) in AgriPLUS™13-00-45, which helps in uptake of positively charged ions (cations) like K+, Ca++ & Mg+.
