Calcium Below Ideal
Calcium is at 65.3% vs the 68% target. While close, we address this through the MetaboPhos-CalSica blend applied at planting to strengthen cell walls and improve nutrient availability.
Magnesium is HIGH
At 24.7%, magnesium exceeds the ideal 10-20% range. High Mg can compact soil structure and reduce Ca and K uptake. No Mg is added in the fertilizer program. Monitor for improvement over seasons.
Potassium is LOW
At 1.4%, potassium is well below the >5% target. K supplementation may be needed in future seasons. Current program prioritises P and Ca correction first.
Agronomist Insight
Due to high Mg and low K, we have compensated with targeted Ca and P application via the MetaboPhos-CalSica blend. K supplementation may be needed in future seasons. Fe, Zn, and Cu are low in the soil analysis -- foliar micronutrients are included at 40 days and flag leaf to correct these deficiencies through the plant.

Nutrient Budget
What the crop needs vs. what the soil provides vs. what the fertilizer delivers for a 4 t/ha wheat target.
| Nutrient | Crop Needs (4t wheat) | Soil Supply (est.) | Fertilizer Plan | Balance |
|---|---|---|---|---|
| N (Nitrogen) | 88 kg | 30 kg (Haney release) | 42.67 kg | -15.33 kg (top dress window) |
| P (Phosphorus) | 15.2 kg | -- | 14.4 kg | -0.8 kg |
| K (Potassium) | 17.2 kg | -- | 0 kg | -17.2 kg (monitor) |
| Ca (Calcium) | 0 kg | Adequate | 25.2 kg | Surplus (soil amendment) |

1
Seed Treatment Pre-Plant · 10 May 2026 (Day -5) ✓ Done
RootSure Why?
Combo pack (BioLift + Rhizoking) — biostimulant seed inoculant
R426/ha
Why this matters
Seeds are treated with biological inoculants to establish beneficial root-zone fungi and bacteria from day one. This gives the plant a head start in nutrient uptake and root development.
2
Pre-Plant Broadcast Before Planting · 12 May 2026 (Day -3) ✓ Done
Nutricat Urea Why?
75 kg/ha -- 34.1 kg N (biologically enhanced)
R1,221/ha
Ammonium Sulfate (AMS) Why?
25 kg/ha -- 5.3 kg N + 6 kg S
R195/ha
Why this matters
Nitrogen applied early to allow soil microbes to process the Nutricat urea (biologically enhanced). AMS provides sulfur, essential for protein formation in wheat. Total pre-plant N: 39.4 kg/ha.
3
Planting -- In-Furrow At Planting · 15 May 2026 (Day 0) ✓ Done
MetaboPhos-CalSica 60/40 Blend Why?
Bin 1 -- 100 kg/ha -- 7.8 kg P + 25.2 kg Ca + 12 kg Si
R684/ha
MAP33 Why?
Bin 2 -- 30 kg/ha -- 3.3 kg N + 6.6 kg P
R384/ha
Why this matters
Phosphorus concentrated in the furrow near the seed for maximum uptake (P is immobile in soil). MetaboPhos-CalSica provides calcium and silicon -- Ca strengthens cell walls, Si improves disease resistance and water management. Total in-furrow N kept below 15 kg/ha to avoid salt burn.

40 Days After Planting Tillering · 24 Jun 2026 (Day 40) ◉ CURRENT
Sap Analysis Why?
1 sample -- Laboratory nutrient analysis
R380/ha
VitaLift Why?
1 L/ha -- Plant metabolism booster
R106/ha
CalCharge Why?
0.75 L/ha -- Stress tolerance enhancer
R80/ha
Micronutrients Why?
1 L/ha -- Foliar Fe, Zn, Cu, Mn blend
R250/ha
Why this matters
First checkpoint. Sap analysis reveals what the plant is actually absorbing vs what the soil provides. Biostimulants (VitaLift + CalCharge) boost plant metabolism and stress tolerance. Micronutrient spray corrects any Fe, Zn, Cu, or Mn deficiencies identified.

Why this matters
Final checkpoint before grain fill. The flag leaf produces ~75% of the energy for grain fill, making this stage critical. Sap analysis confirms nutrient status. Final biostimulant and micronutrient application supports grain quality and protein content.

Agronomist Notes
1
Nutricat Urea Processing
Nutricat urea needs microbial processing -- apply pre-plant N early after emergence or just before planting to allow time for breakdown. The biological coating on Nutricat urea means soil microbes must activate the nitrogen, which takes longer than conventional urea but results in more sustained, plant-available N release.
2
Microelement Deficiencies
Copper, Zinc and Manganese are low in the soil analysis. Include these in the microelement foliar sprays at 40 days and flag leaf. Foliar application bypasses soil lock-up issues and delivers nutrients directly to the leaf for immediate use.
3
Pre-Plant Blend Specification
The Nutricat Urea and AMS pre-plant mix functions as a 1:0:0 (40) + 6% S blend using our biological urea source. This is a custom ratio designed for this specific soil profile -- not a generic off-the-shelf mix.
4
Crop Protection Recommendation
For crop protection, Patostop, Sterisweep and Pellos (Soyro biological fungicides) are recommended instead of chemical fungicides to preserve beneficial micro-organisms established by the biostimulant program. Chemical fungicides would undermine the biological system we are building in the soil.

SAP Analysis
Plant leaf (sap) analysis results from Shortlands Laboratory. Shows actual nutrient levels in the plant as a percentage of the ideal norm.

In-Season Monitor
Disease Risk Assessment
Septoria Leaf Blotch
MEDIUM
Moderate humidity (65-75%) over last 5 days. Monitor closely if rainfall increases above 10mm in 48hrs.
Stripe Rust
LOW
Temperatures above 20°C — unfavourable for stripe rust. Risk increases if temps drop below 15°C with moisture.
Fusarium Head Blight
LOW
No extended wet periods forecast during flowering window. Will re-assess at heading stage.
Russian Wheat Aphid
MEDIUM
Dry conditions favour aphid buildup. Check fields weekly for leaf rolling symptoms. Biological control preferred.
