Khanewal, Punjab –
October 2025:
Background:
Fertilizers are essential for high crop yields, especially for staples like
wheat, maize, and cotton in Pakistan. For years, Diammonium Phosphate
(DAP) has been a preferred choice because it supplies both phosphorus
and nitrogen — key nutrients for plant growth.
The Problem:
Recently, DAP has become expensive and hard to find. As of October
2025, a 50 kg bag costs Rs. 14,500 – 15,500 depending on
the region. In addition, the market is flooded with fake or substandard
DAP, making farmers unsure about its quality. Rising costs and supply
challenges are forcing farmers to look for cheaper and reliable
alternatives without sacrificing crop productivity.
✅ Why Consider SSP + Urea?
Experts suggest a
combination of Single Super Phosphate (SSP) and Urea as a
cost-effective alternative.
- SSP provides phosphorus, sulfur, and calcium, improving soil
health and crop growth.
- Urea supplies nitrogen, essential for plant development.
- Together, they deliver nutrients
similar to a DAP bag, while offering additional benefits for
soil and crops.

⚖️ Recommended Combination for
Cost-Effectiveness
To replace one
50 kg bag of DAP per acre, use:
3 bags of SSP + ½
bag of Urea
- Gives similar phosphorus and nitrogen
levels.
- Adds sulfur and calcium to enhance
soil structure, water retention, and fertility.
- Ratios can be adjusted based on soil
tests and crop type, allowing precise, cost-effective nutrient
management.
Practical Benefits of SSP + Urea
- Improves Soil Health: Sulfur and calcium strengthen soil,
support root growth, and enhance nutrient uptake.
- Suitable for Alkaline Soils: SSP’s mild acidity helps make
phosphorus more available in high-pH soils.
- Affordable & Locally Available: SSP is produced locally, reducing
reliance on imported DAP.
- Lower Risk of Fake Products: Local production ensures genuine
supply.
- Comparable or Better Yields: Studies show SSP + Urea can achieve
similar or superior yields under rain-fed and irrigated conditions.
✅ Sustainability & Long-Term
Benefits
Switching to SSP
+ Urea not only reduces immediate costs, but also maintains
soil fertility over time. Overusing DAP alone can lead to phosphorus
buildup and soil hardening, whereas SSP supports soil life and
long-term productivity.
???? Conclusion
With rising DAP prices
and supply uncertainty, farmers need practical, affordable alternatives.
SSP + Urea offers:
✅ Nutrient balance comparable to DAP
✅ Added soil benefits (sulfur & calcium)
✅ Lower cost per acre
✅ Reliable and easily available
By adopting this
strategy, farmers can maintain high yields, improve soil health,
and reduce reliance on imported fertilizers, creating a more
resilient and self-sufficient agricultural future in Pakistan.
