Agriculture can have significant impacts on the environment. While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption of certain farming practices.

Using Fertilizers Wisely

  • With synthetic fertilizers, farmers can increase the speed of their crop production. Modern farming communities have used synthetic fertilizers for generations, but these fertilizers have put too much nitrogen into farm fields. While this isn’t problematic for grains like corn, wheat, and rice, it is for other foods. The excessive levels of nitrogen in the soil don’t stay there. Unfortunately, th…

Improving Irrigation Efficiency

  • Along with fertilizers, farms need fresh water. The majority of freshwater on the plant goes to the agriculture industry, and farmers use a plethora of techniques to get water and feed their plants. Sadly, many parts of the world have freshwater sources, making it more challenging for farmers to effectively feed their crops. Diverting so much freshwater to farms is environmentally and econo…

Conclusion

  • Farmers and stakeholders need to develop innovative techniques that protect the environment from damage from agricultural modernization. Synthetic fertilizer negatively affects fresh and saltwater around the world. Farms need irrigation, but they need to change how they get water and use it. Without changes, the farming industry will suffer from ir…
