These charts are helpful in determining how much fertilizer is needed to achieve desired feeding rates for your crops. Feeding rates are typically described as either a concentration of nitrogen in parts per million (PPM), or as a certain weight of nitrogen over a specified area of crops.
Concentration (PPM) Charts
This chart provides electrical conductivity (EC) readings for various concentrations of selected Nutriculture formulas. The chart lists the EC values for various concentrations (in PPM) for a number of formulations.
For DIRECT Applications, this chart shows how much fertilizer is required to achieve a desired feeding rate of Nitrogen (in PPM) for a variety of Nutriculture formulations.
For applications made through a PROPORTIONER, this chart shows how much fertilizer is required to achieve a desired feeding rate of nitrogen (in PPM) for a variety of Nutriculture formulations.
Area Application Charts
This chart provides application rates for various Nutriculture formulations in terms of ounces (oz) of fertilizer needed to achieve a desired pounds (lbs) of Nitrogen per thousand square feet (sqft).
This chart provides application rates for various Nutriculture formulations in terms of pounds (lbs) of fertilizer per Acre needed to achieve a desired pounds of Nitrogen per thousand square feet (sqft) of crops.
Note: This information is provided as an aid to developing and maintaining a comprehensive fertility program. Recommended feeding rates are basic estimates for normal conditions with typical soil and water. Actual optimum feeding rates will vary depending on water quality, soil makeup, and crop condition. Feeding rates should be adjusted based on crop response. Consult a qualified extension agent for assistance in developing a fertility program.
