The adoption of biofertilizers in 1970 marked a significant advancement in agricultural practices, utilizing microbial inoculants to enhance nitrogen fixation in soil. This innovation reduced the reliance on chemical fertilizers, promoting more sustainable farming methods. The shift towards biofertilizers reflected growing environmental awareness and the need for sustainable food production systems.

The adoption of biofertilizers in 1970 aligned with the organic movement, resonating with themes in late 20th-century nature poetry. Poets like Gary Snyder and Mary Oliver celebrated the interconnectedness of nature and humanity, often advocating for sustainable practices in their works.
