Conventional farming has acquired a vast market, and one thing it depends on is its fast pace. Chemical pesticides form a huge part of the speedy process. However, they have shortcomings of their own. They tend to strips down the soil of its natural nutrients, which can be disadvantageous to the health of the land and cause desertification.
This article talks about further drawbacks of artificial pesticides.
Soil fertility is an indispensable foundation of agriculture. Soil basically can sustain plant growth and optimize crop yield. Some artificial pesticides block the chemical signals that allow nitrogen-fixing bacteria to function. This leads to the ground being depleted of its nitrogen compounds. Nitrogen-fixing bacteria are nature‘s way of dealing with this issue. Furthermore, crop rotation and fertilizers are used by farmers to help the soil gain back its natural elements.
Animal contamination and deaths
Pesticides, even the least toxic ones, can be severely harmful to wildlife surrounding the land area. Exposure to chemicals can alter the behavior of some organisms and cause significant diseases. Livestock is in direct vulnerability to these pesticides. Animals and birds are also affected by indirect means such as pesticide drift, secondary poisoning, runoff into local water bodies, or groundwater contamination. The impact also vastly depends on the degree of sensitivity of a particular species. Organic agriculture that works on natural pesticides can make a massive difference in this field.
There are several ways through which water bodies are polluted and contaminated by pesticides. Surface water contamination can occur through direct application runoff or drift. Groundwater contamination can occur through direct entry into soil or leaching. These circumstances can be avoided by using pesticides that are less likely to move and choose to persist on water. Feasible buffer strips can be used to separate crops from water bodies. A lot of these can also be avoided by using proper methods of handling, storing, and mixing store-bought pesticides in closed areas.
These were the broader categorization and the most essential aspects of misuse of pesticides in agriculture. Many of these can be avoided by following certain small activities.
