"These insects are able to re-colonise untilled wheat fields that have 'crop stubble', which they use for nourishment as they establish their underground nests. The activity helps more rainwater soak into the ground where plants need it most. The insects also increase the amount of nitrogen - a nutrient needed for plant growth - by a quarter."
So the next time you are walking and see ant or group of ants or termites stop to say a big "Thank you" to these insects, rather than viewing them as pests or not having any importance to humans!!
