Westfert

Westfert Fertiliser

The world’s need for food continues to grow and it remains a challenge to feed the world!

Crops are cultivated slower than demand necessitates. Yield per hectare can only be increased through new technology and through the increased application of nutrients. Better fertilisation techniques will improve the yield and availability of crops worldwide.

Westfert not only supplies fertiliser to its clients but, in cooperation with independent soil expert services, also offers the best options for each client’s specific requirements. Through prescription blends Westfert offers each client the possibility of fertilising their crop optimally.

Elements used in our blends include nitrogen, phosphate and potassium based products:

Products with a nitrogen base:

  • Ammonium sulphate
  • Calcium ammonium nitrate (CAN)
  • LAN / KAN
  • Urea
  • Urea inhibitors

Products with a phosphate base:

  • Monoammonium phosphate MAP

Products with a potassium base:

  • Potassium sulphate
  • Potassium chloride
  • Potassium nitrate

Optional additions

  • Zinc Sulphate
  • Micro-elements (optional)

Prescription Blends

Our prescription blends are formulated, blended and delivered according to the client’s specifications. Using the soil analysis and the type of crop as guideline, a prescription blend is formulated to provide optimal support to the crop and to address soil deficiencies.

With these prescription blends the Westfert technical and sales team formulates products that deliver a cost-effective, optimal yield.


Our main priority remains our long-established good relationship with our client, the farmer. We aim to provide the best service all the time.

Plant Blends

Westfert formulates, blends and delivers the right plant blends according to each client’s specifications and preference.

We formulate granules in the proper combination in order to provide the necessary nutrients in line with the requirements of the soil and the crop. Westfert’s granular plant blends are mostly based on ammonium nitrate as source of nitrogen.

Westfert has its own storage and blending facilities at Hoopstad and Wonderfontein, located in the most important grain production areas of South Africa. We can definitely provide in the farmer’s needs. Please contact a member of our technical and sales team to find out more about specific products that could address your special requirements.

Pre-plant blends

Westfert formulates, blends and delivers the correct pre-plant granular blend according to each client’s specifications and preference.

The pre-plant prescription blends are ideal to lay down nitrogen in the soil before planting commences and provides the peace of mind that the nitrogen will not “disappear” into the ground.

Standard blends

The granular product is named as follows:

For example:  4.3.4 (40)Zn + S

  • The 4.3.4 is the ratio of Nitrogen (N) : Phosphate (P) : Potassium (K).
  • The number in brackets, 40 in this example, is the total % of active nitrogen, phosphate and potassium.
  • To calculate the % N, you add 4+3+4=11 and then divide the 4 by 11 multiplied by 40, which means the N % is 14.5%.
  • The P % is 3 divided by 11 multiplied by 40 = 10.9%, etc.
  • The Zn refers to trace elements added to the blend with special gypsum granules. At this stage micro-elements can also be added.
  • The S refers to Sulphur present in the blend.
