If you talk to farmers, traders, or fertilizer buyers, one name always comes up when potassium is needed — MOP fertilizer. Some call it potash, some say muriate of potash, and some just ask for MOP. No matter the name, the role is simple: MOP helps crops become stronger, healthier, and more productive.
This guide explains what muriate of potash is, how it is used, its NPK ratio and composition, what drives its price and how export shipments work. Agromer supplies MOP in bulk, with quality checks and export documentation.

MOP is one of the most widely used potassium fertilizers globally, making it a preferred choice for farmers, distributors, and bulk buyers. It is commonly referred to as potash fertilizer, MOP, potassium chloride (KCl), or 60% K₂O fertilizer—all describing the same high-potassium product that supports strong crop development, improved yield quality, and enhanced stress tolerance.

What is MOP fertilizer?
MOP stands for muriate of potash, a potassium fertilizer used to improve crop strength and yield.
Potassium is one of the three main nutrients plants need:
- Nitrogen (N) – for leaf growth
- Phosphorus (P) – for roots and flowering
- Potassium (K) – for strength, size, and quality

Composition and formula
In simple words:
- MOP is potassium chloride (KCl)
- It provides around 60% potassium (K₂O)
NPK ratio of MOP
The NPK value of MOP is:
- 0 – 0 – 60
This means:
- Nitrogen: 0
- Phosphorus: 0
- Potassium: 60
That is why MOP is used mainly when crops need potassium.

Why potassium (MOP) is important for crops
Potassium helps plants in many ways:
- improves plant strength
- increases resistance to disease
- improves fruit size and color
- helps plants handle heat and drought
- improves shelf life of crops
That is why potassium fertilizers like MOP are used so widely.
Crops that respond especially well to potassium:
- rice
- wheat
- sugarcane
- maize
- banana
- cotton
- vegetables

How farmers apply MOP
It is usually applied:
- before sowing
- during soil preparation
- mixed with other fertilizers
- as basal application
It is rarely sprayed. It is mainly applied to soil.
What affects the price of MOP?
There is no single fixed price. It depends on:
- global potash supply
- country import duty
- transport cost
- packing size (50 kg bag or bulk)
- seasonal demand
Bulk buyers usually get better rates than retail buyers.

MOP compared with other fertilizers
Many farmers compare MOP with other fertilizers.
MOP vs SOP
- MOP is cheaper
- SOP is better for chloride-sensitive crops
MOP vs DAP
- DAP gives nitrogen + phosphorus
- MOP gives only potassium
Each fertilizer has its own role. This guide may help:

Is MOP safe for plants?
Yes, when it is applied at the right rate.
But excess use can:
- increase soil salinity
- affect sensitive crops
That is why correct dosage matters.
Signs of potassium (potash) deficiency
If soil lacks potassium, plants may show:
- yellow or brown leaf edges
- weak stems
- poor fruit size
- low resistance to disease
In such cases, a potassium application such as MOP helps restore balance.
Limitations of MOP
Like any fertilizer, MOP also has limits:
- not suitable for chloride-sensitive crops
- overuse may increase salt in soil
This is why some farmers mix MOP with organic matter.
