💡 Why Soil Testing Matters
Why should I test my soil?

Soil testing reveals exactly what nutrients your soil already has. Without it, you might over-apply (wasting money) or under-apply (limiting yields).

When NOT to apply fertilizer

Avoid applying on waterlogged soil, during heavy rain, or when crops are drought-stressed. Do not apply urea on hot, dry surfaces.

Fertilizer safety tips

Store in dry, cool places away from children and animals. Wear gloves. Never mix different fertilizers unless recommended.

Farming context: Eswatini

Fertilizer Use in Eswatini

Eswatini (formerly Swaziland) is a small landlocked kingdom in Southern Africa where agriculture is divided between large-scale commercial estates and smallholder farms on Swazi Nation Land. The sugarcane industry, concentrated in the eastern Lowveld, dominates commercial agriculture and is the largest fertilizer consumer. Maize, cotton, citrus, and pineapples are also important crops. Annual fertilizer consumption is approximately 20,000 to 30,000 tonnes, with the sugar estates accounting for over half of total use. All fertilizer is imported, primarily from South Africa through well-established supply chains. Smallholder maize farmers on communal land use significantly less fertilizer than recommended rates, contributing to yields well below potential. The National Agricultural Marketing Board (NAMBoard) and private agro-dealers are the main distribution channels.

Common Fertilizer Types

The fertilizer market in Eswatini follows Southern African standards, with LAN (limestone ammonium nitrate, 28% N) being the most popular nitrogen top-dressing for maize and sugarcane. NPK 2-3-2 (22) is the most commonly used basal compound fertilizer, suitable for maize and a range of food crops on the country's diverse soils. For sugarcane, specialized formulations with high nitrogen and potassium are applied through the growing season. Superphosphate is used for phosphorus application on the country's generally phosphorus-deficient soils. Potassium chloride supplements are important for the sugarcane industry. For citrus orchards and horticultural crops, specialized soluble fertilizers and foliar feeds are available through agricultural supply companies. The proximity to South Africa ensures a wide range of fertilizer products are available through the private sector.

Subsidy Programs & Access

Eswatini supports smallholder farmers through the Farm Input Subsidy Program (FISP), administered by the Ministry of Agriculture. Under this program, registered smallholder farmers on Swazi Nation Land receive subsidized seed and fertilizer packages, typically covering one hectare of maize. The government subsidizes approximately 50 to 60% of the input cost. Farmers register through the Rural Development Area (RDA) offices and their local chiefdom structures. Distribution is organized through designated supply points during the planting season (October to November). The sugar industry operates its own input supply system through the Swaziland Water and Agricultural Development Enterprise (SWADE) and individual mill companies, with input costs recovered from cane proceeds. Access to the FISP requires proof of land allocation from the local chief and registration with the agricultural extension officer at the RDA office.
