Fortifer (Compost)

Fortifer is matured compost (well-composted) produced from dewatered fecal sludge (DFS) and sawdust or market waste. With these combinations the product is able to attain a Nitrogen (N) level of 2.0%. An enrich version has been developed, increasing the N to 3%. The composting process is well monitored and controlled to ensure the production of quality and safe compost.

Fortifer application rate

The application rate of Fortifer is defined by the crop and soil types. However, emphasis is usually placed on crop requirement. Since the Fortifer is being applied to meet the crop’s nutrient requirement, it is important to know the amount of nutrient required by the crop and the nutrient content of the Fortifer. Nutrient requirement for specific crops can be obtained from MoFA website.

Nutrient composition of various Fortifer formulations

This table indicates the nutrient composition of Fortifer formulations.

Nutrient composition of various Fortifier formulation
Fortifier Total N(%) Total P(%) Total K(%) Mg(%) Ca(%) Pb(%) Zn(%) Mn(%) Organic C (%) Organic matter(%) EC(mS/cm) pH
DFS compost 1.7-2.0 1.1-2.1 0.4-0.8 - - 0.02 0.02 0.015 9.1 16 3.0-9.0 6.0-6.6
DFS + sawdust compost 1.1-1.2 1.1 0.3-0.5 - - 0.01 0.01 0.007 16.7 31 1.1-1.7 8.6-8.7
Enriched DFS + sawdust compost 2.9-3.8 0.73-0.90 0.5-0.6 0.42-0.43 0.17-0.20 0.01 0.01-0.02 0.02-0.03 30.23 52 7.8 7.2-2.3

With Fortifer nutrients are released gradually through mineralization to the crop, however, with the enrich Fortifer about 50% of nutrients are made readily available to the crop. It is important to note that the Fortifer is rich in organic matter which will improve on soil physical and biological properties unlike chemical fertilizers.

Application method

The Fortifer application methods vary based on the type of formulation.

  • The pellets, usually enriched, should be placed about 5cm from the base of the plant.  The pellets can be placed on the soil surface or buried to about 5cm. Whether placed on the soil surface or buried, the pellets can be placed at one side of the plant (side placement) or around the plant (ring placement) maintaining the 5cm gap between the plant base and fertilizer. Methods of inorganic fertilizer application (such as ring placement, band placement and broadcasting) can be applied to the Fortifer pellets where applicable.
  • The powdered Fortifer (enriched or non-enriched) can be incorporated or mixed with the soil or planting media. It can be applied on the soil surface or ploughed into the soil one week to planting or one week after planting. This may vary depending on the crop. A gap of 5cm should be left between the Fortifer and the plant.

Crops and Fortifer application recommended

The table below shows the recommended application rate of N and the quantity of Fortifer needed for that recommendation.

Crop MoFA recommendation (kg N/ha) Fortifier (3% N) Quantity required (kg/ha) Equivalent in bags (50kg) NPK By Fortifier (N-P-K-OM)
Maize 90-120 4000 80 120-52-24-33
Cabbage 70-102 3400 68 102-44-20-33
Rice 138-168 4600 92 138-60-28-33
Banana 110 3680 74 110-48-22-33

NB: The N application rate is based on recommended rates provided by MoFA
