Soil Analysis & Haney Test Import

Tiaan's combined approach: standard soil analysis (NviroTek) + Haney test (Soil Health Support Centre) together give a complete picture of soil chemistry and biological health.

NviroTek Soil Analysis

Standard soil chemistry: pH, P Bray, K/Ca/Mg/Na (AmAc extraction), micronutrients (DTPA), S, Fe, SOM%, CEC, resistance.

Combined Soil + Haney View

Tiaan's approach: combine standard soil chemistry with Haney biological data for a complete picture. The standard analysis shows what's IN the soil; the Haney test shows what's AVAILABLE to the plant.

How it works: Standard soil analysis measures total extractable nutrients (chemical availability). Haney test measures biologically available nutrients (what roots can actually access via organic acids). The difference tells you how much of the soil's nutrient bank is locked up vs accessible. High standard K but low Haney K = K is present but biologically unavailable — address soil biology, not K fertilizer.

AI Learning & Feedback

The AI learns from every programme you create. This section shows what it's learning so you can correct it before it goes down the wrong path. Transparency is key — the AI must report, not assume.

Teach the AI Directly

Tell the AI something you want it to learn — rule, preference, or correction. It will log it against your name and fold it into future recommendations.

What the AI Has Learned (Last 30 Days)

Pattern

Western Cape wheat: K supplementation rarely needed Observed across 8 programmes (Swellendam, Overberg). Soil K reserves consistently adequate (AmAc K >120 mg/kg). AI now defaults to zero K for WC wheat unless soil K <80 mg/kg.

Pattern

AMS always paired with Nutricat Urea in pre-plant 100% of Tiaan's programmes include AMS alongside Nutricat Urea. AI now treats this as a standard pairing for wheat/canola. Reason inferred: S requirement + N supplement.

Uncertain

MetaboPhos-CalSica ratio: always 60/40? All 6 programmes use 60/40 blend. AI is unsure if this is universal or soil-specific. Should the ratio change based on soil Ca:P levels?

Uncertain

Foliar micronutrient mix: standard or customised? All programmes include "Micronutrients 1 L/ha" at 40 days and flag leaf. AI cannot determine if this is a fixed product or a custom mix based on soil deficiencies. Please clarify.

Conflict

Rustenburg vs Swellendam: different N rates for same yield target Randolf uses 20 kg N/ton for Rustenburg maize. Tiaan uses 24 kg N/ton for Swellendam wheat. AI flagging this as a potential regional norm difference (not an error). Confirm this is area-specific?

AI Learning Summary

Programmes Analysed

Across 8 farmers

Patterns Identified

8 confirmed, 2 uncertain, 2 conflicts

Needs Your Input

2 uncertain + 2 conflicts

How this works: Every time you create or modify a programme, the AI analyses it against all previous programmes. It looks for patterns (product pairings, rates, timing), flags uncertainties (things it can't determine from data alone), and reports conflicts (where two agronomists do things differently). You confirm, correct, or explain — and the AI updates its understanding. This builds the Grocopedia over time.

Recommendation Constraint Rules

These rules are automatically applied to every programme recommendation before it reaches the farmer.

1. Growth Threshold: If growth % < 30%, recommend growth hormone (VitaLift) BEFORE trace elements. A stunted plant cannot utilise micronutrients.

2. pH Rules: High pH (>7.5): avoid ammonium-based N, consider acidifying fertilizers. Low pH (<5.0): check Al toxicity, consider lime.

3. Economic Override: Recommendations must be budget-aware — what is economically viable, not just theoretically optimal. Priority: N → P → K → S → Ca → Mg → Zn → B → Mn → Cu → Fe → Mo.

4. Tank-Mix Limit: Max 4 products per spray. Saturated solutions burn the plant. If more corrections needed, split across spray windows.

5. Spray Windows: Wheat: 3, Canola: 3, Potatoes: 2, Maize: 3. Plan corrections across available windows — don't overload a single application.

6. Philosophy: Do NOT optimise to 100% on every nutrient. Focus on the nutrients that move yield — practical, executable, budget-conscious. That's the SureWay advantage.

7. Area-Specific: AI builds region+crop knowledge pods. "Wheat in Rustenburg" uses Randolf's approach. "Wheat in Swellendam" uses Tiaan's. Region + crop + agronomist = unique context.

Grocopedia — SureWay Knowledge Base

A living knowledge base where agronomists input their norms and interpretations. AI combines agronomist input with research data to create SureWay-specific standards. Team reviews, comments, and the system refreshes weekly.

Critical Points of Influence (CPI)

Independent agronomist view of ideal foliar spray timing, separate from the Sureway defaults. Edit to reflect your experience — the AI blends CPI timing with SAP/soil triggers when building programmes.

Crop	Stage	Window (days after planting)	Purpose	Priority
Wheat	Tillering	30–45	N topdress trigger	High
Wheat	Flag leaf	55–70	Micronutrient correction, disease window	High
Canola	Rosette	25–40	B + N micro-supplement	Medium
Canola	Flowering	60–80	B at flower set, S top-up	High
