Legumes have root nodules in which Nitrogen Fixing bacteria are present . These nodules occasionally burst open . So planting Legumes in association with the Maize I think would mean that the Nitrate Ion concentration of the soil would increase hence the Maize crop will thrive and produce high quality yeild and so this would reduce the need of fertilisers as well.

Was the first question microvilli? I wrote cilia then cancelled it and wrote ciliated cells
But how can the kidney tubules have microvilli it doesn't make sense
