Die effek van verskillende graanopbergmetodes op die aanwending van kapitaal in 'n mielieboerdery in die Noordwes Provinsie

[摘要] English: According to Liversage (2003: 1) maize was marketed through the one channel marketing system between 1944 and 1994. According to this system the Maize Board and its agents (the former agriculture co-operatives) were responsible for the buying and storing of maize in South Africa (Maize Board 1987: 134-147). After the closing of the Maize Board, a free market system was implemented and currently any person or organization can store maize (Murray, 2011: personal communication) in South Africa. Due to the above mentioned changes, 1.85 million tons of storage capacity was erected on farms in South Africa since 1996 (SIQ, 2011). Apart from storing maize at the silos of commercial storage companies, maize can also be stored on the farm by using zinc silos, silo bags and grain dams according to Genis (2012). If storage takes place on the farm it will need the erection of storage structures. Dhyuvetter (2007: 4-6) showed that additional capital is needed to erect new storage structures on the farm. According to Steitz & Ehmke (2005) any capital expenditure, influences the farm over a long period and need careful planning (Boehlje & Ehmke (2005: 1). According to Louw (1996: 20) models for complete farm planning can be used to evaluate the effect of capital spending on the farm. According to Koch (1992: 20) these models take the soil, farm operations, market plans and capital resources into account when different options is evaluated by developing varies scenarios. There is currently no farm planing model available in South Africa witch can be used to evaluate the effect of different storage methods on the use of capital resources of the farm. In this study 'n holistic farm planning model is developed to be use in evaluating the effect of different storage methods on the use of capital on a maize farm. The effect of the use of commercial silos and the use of zinc silos, silo bags, plastic dams and zinc dams is evaluated in the study. The effect of certain variables like the size of the farm, the distance of the farm from the commercial silo and the marketing strategy are evaluated in the model by using different scenarios. According to the results of the study, the highest margin after specified cost was realized by using zinc silos. The Net present value was used to evaluate the application of capital on the Farm. The use of commercial silos realized the highest Net Present Value. Based on the results of the study the size of the farm, the marketing strategy, the distance between the farm and the commercial silo and the method of transport between the farm and commercial silo, can influence the choice of storage method if the calculation of net present value is used as a tool of measurement. According to the results of the study it is important to take the effect of the fixed and variable costs into account when evaluating the different storage options on a Farm. It is even more important if the size of the harvest varies.
