Today, I will continue with my post on monoculture farming and the soil pollution that is caused.
Environmental impacts of using fungicides and pesticides: Soil Contamination and degradation
Pesticides undergo degradation to transform into less toxic/harmful substances to become more environmentally compatible to its applied areas. Degradation involves both biotic and abiotic transformation processes. Biotic transformation is influenced by microorganisms while abiotic transformation involves processes such as chemical and photochemical reactions. Redox gradient in soils, sediment types or aquifers often determine which transformations can occur (NCBI, 2009).
Transformed products (TP) from pesticides remain problematic because some are are more potent than their parent forms.For example, they can increase in their potential to reach and pollute drinking water resources such as groundwater and surface waters, if their polarity is higher than the parent forms’ (NCBI, 2009).
Heavy treatment of soil with pesticides and fungicides can cause populations of beneficial soil microorganisms to decline. Overuse of chemical fertilizers and pesticides have effects on the soil organisms that are similar to human overuse of antibiotics. Indiscriminate use of chemicals might work for a few years, but in the case of TR4, a new strain of the Panama disease, pathogens prove to be mutating and evolving, immuned to the chemicals.
That will be all for today. Stay tune to (3) , which will continue with the water and air pollution through the use of chemicals on the plantation, and the health effects on the farmers. 😀
