What does NPK stand for?

N stands for Nitrogen, P for Phosphorus (expressed as P₂O₅), and K for Potassium (expressed as K₂O).

What calculations are supported in this mixer?

You can calculate custom target macronutrients, target NPK percentages, PPM dilutions, and exact batch recipe formulations.

Deficiencies Detected in Formulation

Because you selected a single or unbalanced compound fertilizer source (Urea (46-0-0)), your targets are partially unfulfilled:

Phosphorus Deficit: 0.5 %. Consider adding a TSP (Triple Superphosphate) or MAP booster.
Potassium Deficit: 0.5 %. Consider adding a Potassium Sulfate (SOP) booster.

Agronomic Recipe & Mixing Guide

Step 1: Set Reservoir Volume / Area

Pour exactly 1 L of clean, pure water (preferably RO or distilled water if doing hydroponics) into your mixing reservoir.

Step 2: Weigh Dry Salt / Fertilizer

Using a precision scale, weigh exactly 21.74 grams of Urea (46-0-0) dry powder.

Step 3: Dissolve & Distribute

Add the weighed powder slowly to the water while stirring. Continue agitation for 2-3 minutes until all crystals dissolve completely.

Step 4: Check Ratios and Supplemental Blends

Your base solution is ready! It provides a strength of 1 % N, 0 % P, and 0 % K. ⚠️ Note: Supplement with Single-source Boosters to address the unfulfilled deficits identified above.
