Farmer's Weekly posed in interesting question with one of their September, 2017 articles. Essentially they asked "How many harvests are left in your soil?" Maria-Helena Semendo, speaking at World Soil Day (2016) stated that the world's topsoil could be gone within 60 years should the current degradation continue. Some of the main causes of soil degradation include chemical-heavy farming methods, deforestation, erosion and global warming.
Professor Raj Patel points to runoff water from farms often contaminated with high volumes of fertilizer and other chemicals as being a culprit. “The story of industrial agriculture is all about externalizing costs and exploiting nature,” Patel states.
South African farmers are already taking the lead by becoming more ecologically accountable, by incorporating green farming practices and turning to sustainable farming methods and water conservation. One of the methods South Africans employ are irrigation scheduling, or the precise control of irrigation.
The question now remains how does irrigation scheduling and sustainable farming form a beneficial symbiotic relationship?
