How to calculate fertilizer rates?

Did you have a go at it just as with pH , each case of flora has a preferred electric conductivity ( EC ) range within which it can prosper ? In world-wide , though , if your EC is very low , your plant likely does n’t have enough food . On the other hand , if your EC is very high , you incline the risk of burning your roots or creating toxic buildups .

All plants need the right amount of food ( food ) in orderliness to turn . Electrical conductivity ( EC ) is an of the essence measurement that indicates the full amount of nutrients available to your plants .

When nutrients break up in pee , they divide into ions . For example , atomic number 19 nitrate dissolve into a K ion and a nitrate ion . Each ion carries an electric charge , which creates the voltage for electrical energy to move through a solution . The more ions present , the better the water can conduct electricity .

Plants only absorb nutrient when they are usable in an ionic form . That ’s why EC is a well indication of the overall intensity of your nutrient solution .

Electrical Conductivity & Fertilizer ConcentrationRegular monitoring of the electrical conduction ( EC ) of your nourishing root is a life-sustaining part of any fertigation programme . Electrical conduction is the ability of a answer to behave an electrical current . Most component ( works indispensable or other ) that are soluble in H2O will contribute to the conductivity of water system or a nutrient root . As a final result , the EC of a alimentary solution will increase as the water - soluble fertiliser concentration in the answer is increased . By have intercourse the EC of a water - soluble fertilizer solution , you’re able to augur the part per million ( ppm ) of nutrient your plant are receiving or that remain in your overflow water system .

Each H2O - soluble fertilizer blend has a unequaled EC profile based on its concentration in solution due to the composition of the intersection . The follow chart can be used to relate the EC of your Plant - Prod MJ TM nutrient feed with the associated percentage per million ( ppm ) of Nitrogen :

Measuring ECMost meter used by our grower are calibrate in mmhos per cm or mS per cm , which are standardised building block . The data point yield here on our piddle - soluble fertilizers use the same measurement . The above mesa can be used to valuate the accuracy of water supply - soluble fertilizer injector systems by following these tone :
