The Milagro Beanfield War OST (1988)

Hi!

Can anyone identify two songs from The Milagro Beanfield War OST (1988) ?

The scenes in which the songs in question are:

1. When Joe Mondragon (Chick Vennera) is ploughing the beanfield with tractor.

2. When Ruby Archuleta (Sonia Braga) is asking the people of Milagro to sign petition.

3. And this 1 with youtube link: https://youtu.be/6uy2qSmlreQ

Neither IMDB.com nor Grusin.net helps. Those songs are not in Dave Grusin "Migration" album, that's why I ask for help.

Thanks.

anyone?
