Afield is abandoned, and an invasive plant that can live in nutrient-poor soil moves into the field. if the land is later cleared of this invasive species and it is discovered that the soil has an abundance of nitrogen compounds, what conclusion can best be made

THIS IS THE BEST ANSWER ๐Ÿ‘‡

The inference that can be drawn is that the invasive species is probably a nitrogen-fixing species. These species do not require nitrogen from the soil to grow and survive. They are able to take Nitrogen (in the form of N2) from the atmosphere.
