ARTICLE 1: Best Fertilizer Program for Maize in the Free State (Full Article)

Introduction:

Maize farming in the Free State requires balanced soil nutrition and correct fertilizer timing. The region’s soils often lack nitrogen, phosphorus and magnesium, making fertilizer management essential.

 

1. Soil Testing is the First Step
Before applying fertilizer, test for:

• pH
• Phosphorus
• Nitrogen
• Magnesium
• Organic matter

 

2. Recommended Fertilizer Program

• At Planting: 2:3:2 (22) or 2:3:4 (30) blends
• Top Dressing (4–6 weeks): LAN (28%) or Urea
• Foliar Feed: Apply Zn + B + Mn liquid foliar to boost kernel development
•  

3. Improve Soil pH First

• Low pH reduces fertilizer absorption. Apply agricultural lime 2–3 months before planting.
•  

4. Final Tips

Apply gypsum on sodium-rich soils

Ensure even spreading

Monitor crop colour
