Welcome to the CroPulse Fertigation Calculating Algorithm!
This tool will help you calculate the necessary nutrient elements values for your crops
Fertigation units manufactured by CroPulse Ltd. are designed for precise dosed application of nutrients to the root zone of plants.
The fertigation unit's model is selected in accordance with the cultivation method, production volume, type of agricultural crop and other terms and conditions.
For the correct selection of the fertigation unit's model, please contact us at Info@CroPulse.net.
The presented calculating algorithm is an auxiliary tool for the appropriate use of CroPulse's fertigation units, as well as separately installed Mixrite dosing pumps.
It allows to automatically calculate the composition of nutrient solutions intended for application through fertigation units and separate Mixrite pumps.
Attention!
This calculating algorithm performs calculations based on the recommendations of the basic needs of the main agricultural crops in nutrients provided by leading fertilizer manufacturers and the results of the calculations can be considered only as basic (not taking into account the totality of specific terms and conditions, such as chemical analysis of water and soil, the applied volume of irrigation, the vegetation phase of plants, monitoring the actual physical condition of plants, etc.).
CroPulse Company is under no circumstances responsible for any possible crop losses or deterioration in its quality, or any other possible problems that the user may encounter in connection with the use of the presented calculating algorithm.
When preparing a solution recipe, it is necessary to follow the recommendations on chemical compatibility of different types of fertilizers.
Failure to follow the recommendations may result in the formation of unwanted chemical compounds and solid sediment in the fertilizer solution, which can negatively affect plants and also lead to pump MixRite failure.
Each of the incompatible fertilizer solutions must be supplied through a separate pump.
The fertilizer used, must be water solible.
