| Description | In order to take advantage of market proximity, intensive livestock-production units are established on the outskirts of cities. Approximately 70 percent of the poultry and pigs in the Republic is kept in the Transvaal and Western Cape. The total amount of wastes produced in intensive animal units in South Africa is estimated at 9,8 million tons per annum. Waste contains large amounts of plant nutrients, and if handling is incorrect, serious pollution will occur. Pollution takes place when plant nutrients and salts infiltrate the soil in excess of the crop requirement and would result in saline soil or pollution of the groundwater. Waste washed away by surface run-off, will render rivers and dams useless. Water contaminated with pathogenes present in animal waste can cause and spread disease. Although the technology for the safe handling of animal waste exists, the number of cases of pollution is annually increasing. Om naby die mark te wees, word intensiewe diereproduksie-eenhede om die groter stede gekonsentreer. Ongeveer 70 persent van die hoenders en varke van die Repubiiek word in Transvaal en in die Wes-Kaap aangehou. Die totale hoeveelheid mis in intensiewe diere-eenhede in Suid-Afrika geproduseer, word op 9,8 miljoen ton per jaar beraam. Hierdie mis bevat groot hoeveelhede plantvoedingstowwe wat, indien dit verkeerd gehanteer sou word, ernstige besoedeling kan veroorsaak. Die besoedeling vindplaas deur voedingstowwe en soute wat die grond insypel en, indien daar meer as wat die plante benodig, toegedien word, sal die grond verbrak, of grondwater sal besoedel word. Mis wat saam met oppervlakteafloopwater vervoer word, maak riviere en damme onbruikbaar. Water besmet met patogene afkomstig van dieremis kan siektes veroorsaak en versprei. Alhoewel daar ’n tegnologie bestaan om diereafval veilig te hanteer, neem die aantal gevalle van besoedeling nog jaarliks toe. | |
