Chemigation refers to the application of what through irrigation systems?

Chemigation involves the application of fertilizers or pesticides through irrigation systems to deliver these substances directly to the plants. This method allows for the efficient distribution of chemicals, ensuring that they reach the root zone of the plants effectively and minimizing the potential for runoff or evaporation losses.

Using irrigation systems to apply these materials maximizes their effectiveness, as they can be integrated into the watering schedule, promoting even distribution across the field. Additionally, chemigation can help in reducing labor costs and enhancing application precision, contributing to better pest control and nutrient management in agricultural practices.

Water, herbicides, and soil amendments do not adequately encompass the broader application scope that chemigation allows, as it pertains specifically to the use of both fertilizers and pesticides. This multifaceted tool captures the essence of integrating pest management and nutrient supply into existing agricultural practices.
