- 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
See the “Monthly Bulletin” on the South African Grain Information Service (SAGIS) website for updated export/import information.
- Soybeans account for the largest share of global oilseed demand (USDA, 2018).
- The largest producers of soybeans are the US, Brazil, Argentina, China and India. Brazil is the top exporter, followed by the US, Argentina, Paraguay and Canada. The biggest importer by far is China, followed by the EU, Mexico, Egypt and Japan (USDA, 2018).
- The major producers in Africa are South Africa, Nigeria, Zambia, Malawi, Benin and Zimbabwe.
- The SADC Secretariat and German Development Corporation‘s Profiling of the Regional Agro-Processing Value Chains in the SADC Region (March 2019) includes a look at soybeans.
- Analysis from Bureau for Food and Agricultural Policy (BFAP) prototype farms indicated that local farms were less competitive compared to international counterparts such as Brazil, Argentina and the United States of America. This was driven mainly by lower yields and higher cost for selected input items (BFAP, 2018).

South Africa imports and exports
- Imports account for a declining share of soybean oil and oilcake consumption in South Africa. Oilcake imports, for example, shrunk from 71% in 2008, to 27% in 2018 and are projected at a mere 13% in 2028 (BFAP, 2019). After five years of rapid expansion in this sector, South Africa is expected to trade close to self sufficiency, with a sensitive balance being maintained between supply and demand (BFAP, 2019).
- The domestic price (SAFEX) normally follows the import derived price (based on soymeal and oil). The import tariff for soybeans is 8% of the fob price.
- With regard to exports, phytosanitary requirements and quality standards must be adhered to and a PPECB certificate must be obtained.
Local business environment
Find the “Regulations relating the grading, packing and marketing of soya beans intended for sale in the Republic of South Africa” on http://agbizgrain.co.za.
- Soybean production surpassed sunflower in 2012, becoming the country’s most important oilseed crop.
- Soybean is mainly produced in Mpumalanga, Free State, KwaZulu-Natal and Limpopo Provinces. These four provinces account for approximately 80% of the total soybean crop (DAFF, 2018).
- 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 and oil is an increase in the demand for animal feeds as a result of the country’s growing middle class and the increased demand for high protein food.
- Soybean consumption in the country is estimated at 32% for oil and oilcake, 60% for animal feed (especially in the broiler and egg industries) and 8% for human consumption (DAFF, 2018).
- Over the past 10 years, the gross producer value GPV for soybeans increased more than any other agricultural commodity (ABSA, 2018).
- 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 – www.sagis.org.za.

For the grower

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

National strategy and government point of contact
The Agricultural Policy Action Plan 2015 – 2019 (APAP) document deals with soybeans within the context of the Poultry/Soybeans/Maize Integrated Value Chain. It identifies the role played by soybeans as a key constraint in the production costs of, amongst others, broilers and layers.
In terms of growth in gross value of production (2013-2017) and share of total agricultural production value (2013-2017), DAFF (2018) placed soybeans in the top 10 agricultural products.
A motivation for the new R65 levy (March 2019) on soybeans sold can be read at https://agbiz.co.za/uploads/AgbizNews19/190301_Soybean%20levy.pdf.
