Crops in a field
Record a bamboo or similar plant (it’ll need to have somewhat dry leaves) being continuously stroked and shaken. Then layer these recordings and use them for the for sound of crops swaying in the wind. For added realism, add some wind ambience as well, and whenever there’s a stronger gust of wind, time the rattling of the bamboo with this to give the effect of the wind picking up in the crops.
