Dear Mr. Caporrizo:
I am not aware of many solutions for mushrooms.  However, your local ag agent may have some good ones.  Please refer to an answer to the same question dated July 12 this year.
Increasing nitrate or nitrogen (N) in your lawn should be easy.  For summer grasses, frequent low N applications of N should feed the grass.  I would use one lb. of N per thousand sq. ft.(M) per month for four months for Bermuda and less for other types like St Augustine or Centipede.  Do not overfertilize these last.
For winter grasses, fescue and bluegrass, fertilize in the fall with one to two pounds of N per thousand sq. ft. and again in the early spring, for your location.
Alternately, you may apply a high quality compost to the lawn in the dormant season, usually early fall at the rate of one cubic yard(CY) per thousand sq. ft.  This may be reduced every year to the eventual rate of one half CY/M annually.  Seasonal applications of granular fertilizer may be applied at low rates if needed - one half to one lb of N in early growth season.
Use of compost will increase the residual bank of N in your soil.  The forms of residual N are non soluble and available upon demand of roots and plant enzymes and the action of the soil nutrient cycle.
