In agriculture cultural control is the practice of modifying the growing environment to reduce the prevalence of unwanted pests. Examples include changing soil pH or fertility levels, irrigation practices, amount of sunlight, temperature, or the use of beneficial animals (e.g. chickens) or insects (e.g. ladybugs). These can detrimental effects to the ecosystem surrounding the area given the pesticide if it leaks, which could change an ecosystem drastically depending on its specific effects and cultural control.
