Fertilizer Blend Order
and Production Custody
A custom blend is not fully identified by its target grade. Custody preserves the approved request, responsible blender and site, exact components and lots as represented, formulation revision, production and weighing evidence, rework or carryover, load identity, delivery statement and receiving decision.

HOW TO READ THIS PAGE
Visual explanationA diagram or operating scene makes the relationship visible.
Structured modelA flow, comparison, capability set, or boundary map organizes the idea.
Guided explanationOriginal prose connects the concept to its operating context.
01 / Overview
Protect the handoff between
nutrient intent and physical blend.
State and national systems treat bulk and customer-formula products differently, and Canadian rules establish their own registration or exemption logic. A farm system should preserve the exact applicable supplier documents rather than invent a universal blend-ticket template.
NRCS source-rate-time-place planning provides the agronomic context. Blend custody answers a different question: what material did the supplier represent it produced and deliver against that authorized request?
02 / Custody loop
Authorize, stage, produce,
load and reconcile.
01AUTHORIZE / 01Freeze the controlled requestQualified nutrient plan reference, field or enterprise, source intent, target represented analysis, quantity and units, product and supplier scope, delivery window, documents and substitution gate
02STAGE / 02Identify represented componentsComponent product, responsible party, label or authority reference, lot or inventory identity, quantity and units, storage source, approved substitution, return and unexplained difference
03PRODUCE / 03Preserve the production eventSupplier facility, formula and revision, equipment and scale identities, timestamps, operator, measured component quantities, sequence only as supplier evidence, carryover, rework, deviation and review
04HANDOFF / 04Bind load to deliveryBlend or batch identity, load, vehicle or compartment, weight evidence, ticket and documents, seals where used, destination, receiver, accepted quantity, discrepancy and inventory admission

04 / Practice
Use identifiers that survive
from blender to field.
Preserve original measurements
Retain component and total units, scale or meter identity, timestamps, rounding, conversion and uncertainty without hiding them behind a target grade.
Build material genealogy
Connect component lots to blend, batch, load, split delivery, receiving lot, field issue and remaining quantity.
Escalate deviations
Separate overage, shortage, substitution, carryover, rework, contamination concern, document conflict and unexplained balance from conforming production.
05 / Boundaries
Custody evidence is not
a blending instruction.
No formulation, mixing sequence, compatibility, equipment, calibration, handling or application instruction is provided.Use licensed or qualified suppliers, current law, labels, SDSs and professional procedures.
Target analysis does not prove blend uniformity or actual composition.Preserve supplier controls, sampling and laboratory evidence only within their represented scope.
Do not expose proprietary formulations beyond authorized operational need.Use role-based access while retaining sufficient identity and audit evidence for the farm.
