Nutrient Mix Consumption at 99% dosing-system delivery efficiency: a worked example

What does the result look like when dosing-system delivery efficiency reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when sizing a tote or batch-tank refill for the next crop cycle, checking whether on-hand stock covers a holiday weekend, or planning fertilizer purchase orders for a leafy green, herb, tomato, or cucumber program.

The inputs for this scenario

  • Active canopy area to feed: 5,000 sq ft (unchanged)
  • Daily nutrient solution use per square foot: 0.1 L / sq ft / day (unchanged)
  • Dosing-system delivery efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Theoretical daily solution required = active canopy area × daily nutrient solution use per square foot) to the inputs above produces each figure below.
  • At this operating point the engine returns 505 L for required nutrient solution to mix, the number this scenario is built around.
  • At this operating point the engine returns 500 L for theoretical daily solution required.
  • At this operating point the engine returns 5.05 L for drain-to-waste and bleed-off allowance.
  • At this operating point the engine returns 99 % for dosing-system delivery efficiency.

How this compares with the baseline

  • Against the tool's baseline example, where dosing-system delivery efficiency sits at 90% and the headline result is 556 L, this scenario comes in 9.09% below the baseline at 505 L.
  • A figure at this level is achievable when dosing-system delivery efficiency is genuinely sustained, not just peaked for a shift. It assumes a constant per-square-foot feed rate, so it does not adjust for crop growth stage, transpiration swings with climate, or recirculating systems that reclaim runoff.
