  • This is the fourth largest crop in the world after maize, wheat and rice.
  • Soybeans are an important source of vegetable oil and protein worldwide and there is growing interest in soy products amongst people who want to be healthy. Soy contains significant amounts of all the essential amino acids for humans.
  • Soybean seeds can be eaten as a vegetable. When processed they give soy milk. Soy sauce can be made from mature fermented beans, while roasted seeds can be used as a coffee substitute. Soy flour, another possibility, is used as additives and extenders to cereal flour, meat products and in health foods.
  • Soybeans is also a biofuel crop.
  • Soybean meal is a very rich protein feedstuff for livestock while the vegetative portions of the plant can be used as silage, hay, pasture or may be ploughed in as green manure.
  • The oil is used in the manufacturing of paints, linoleum, oilcloth, printing inks, soaps, insecticides and disinfectants. The lecithin phospholipids that are obtained as a by-product of the oil industry are used as wetting and stabilising agents in food, cosmetics, pharmaceuticals, leather, paint, plastic, soaps and detergent industries. Soybean meal and soybean protein are used in the manufacture of synthetic fibre, adhesives, textile sizing, waterproofing and fire-fighting foam. The straw can be used to make paper that is stiffer than that made from wheat straw.
  • It is an excellent rotation crop with clearly discernible benefits to crops following.

International business environment

  • Soybeans account for the largest share of global oilseed demand (USDA, 2023).
  • The largest producers of soybeans are Brazil, US and Argentina (USDA, 2023). Brazil is the top exporter, followed by the US. The biggest importer by far is China, followed by the EU (USDA, 2023).
  • The largest producers of soybean meal are China, US, Brazil and Argentina (USDA, 2023).
  • Argentina, Brazil and the US are the top exporters. The biggest importer by a large margin is the EU (USDA, 2023).
  • The largest producers of soybean oil are China, US, Brazil and Argentina (USDA, 2023).
  • Argentina, Brazil and the EU are the top exporters. The biggest importers are India, Bangladesh, Algeria, Peru and Morocco (USDA, 2023).
  • The major producers of soybeans in Africa are South Africa, Nigeria, Zambia, Malawi, Benin and Zimbabwe.
  • Analysis from Bureau for Food and Agricultural Policy (BFAP) in 2020 noted that South Africa could improve its competitiveness by either (i) achieving higher yields, or (ii) reducing the cost to produce a tonne of soybeans. In Argentina and Brazil the cost is around 56% of what South African farmers pay. Here the cost of R780 per hectare is well above (15%) the international sample average (BFAP, 2020).

    • South Africa is a small player in the global soybean market, accounting for only 0,5% of global soybean production. This means that South African soybean prices are primarily influenced by market developments in significant soybean producing and consuming countries.
    • However, the sharp increase in production since 2020, combined with concerns on port efficiency pushed soybean prices below export parity in early 2023 (BFAP, 2023).
    • In the 2022/23 marketing year SA imported 4 154 tons of soybeans and exported 277 504 tons. The imports came from Zambia. Exports went to Malaysia, Thailand, Bangladesh, Vietnam, Zimbabwe and Mozambique (SAGIS, 2023). South Africa’s becoming a net exporter of soybeans is seen as a “true success story in South African agriculture” (Kirsten and Meyer, cited by Majola, 2023).
    • With regard to exports, phytosanitary requirements and quality standards must be adhered to and a PPECB certificate must be obtained.

Local business environment

  • Soybean production surpassed sunflower in 2012, becoming the country’s most important oilseed crop.
  • Soybean is mainly produced in the Free State (43.7%), Mpumalanga (29.1%), North West (11%) and KwaZulu-Natal (7.9%) (DALRRD, 2024).
  • Soybean production has more than doubled since 2020, to exceed 2.8 million tonnes by 2023 (BFAP, 2023).
  • Depending upon local conditions, soybeans are typically planted in November through December. The plants react to day/night length ratios which stimulate the reproduction process. Planting in January will result in a shorter plant with lower harvest potential, as the days shorten during growth. On ripening, the leaves turn yellow and the moisture content of the seeds drops – from about 65% to 14% within 14 days – given that the weather is dry and hot.
  • What has driven significant growth for soy oilcake remains the increase in the demand for animal feeds. As the livestock sector is supported by beef exports and actions such as the Poultry Masterplan, this is expected to continue. Soybean oilcake has a higher protein content and favourable pricing compared to alternatives such as fishmeal (BFAP, 2022).
  • Soybean consumption in the country is estimated at 87.5% for oil and oilcake, 10.7% for animal feed (especially in the broiler and egg industries) and 1.7% for human consumption (SAGIS, 2023).


  • No statutory levies are applicable and the marketing of oilseeds is free, the South African Futures Market determining domestic prices on a daily basis. The relative prices of other grain products, the exchange rate, availability of seed, availability and landed cost of imported crude oil, as well as plantings of other field crops mainly determine market prospects for soybeans.
  • The Soybean marketing season in South Africa commences on 1 March.
  • Statistics (e.g. crop estimates, export/import etc) may be found on the SAGIS website –

Reasons for Soybean Growing

  • Diversification away from maize
  • The growing animal feed demand
  • Growing production of soyfood
  • Bio-diesel plant from soybeans
  • Soybeans is one of a few crops that can be planted in rotation with wheat to ensure two crops per annum
  • Crop rotation benefits include increased yields for both crops, and simplified weed and pest control.
  • Since South Africa has to import soy, marketing is not a problem.
  • Increased local production will save the country millions in foreign exchange
