|Most fertillizers are harmful to the environment and most state do not use near running stream, etc.We have a stream that runs in back of our house. What do you suggest to use to fertilize the lawn ?

|Fertilizer runoff is a real concern, especially if your lawn is near a stream. The most offensive chemical is phosphorous (the middle number on a fertilizer package) which causes excessive algae bloom in rivers, lakes and streams. You can use pure nitrogen such as milorganite (an organic source of nitrogen) or you can find a packaged lawn fertilizer with zero or nearly zero percent of phosphorous. Most lawn fertilizers are a 3-1-2 ratio of NPK such as a 21-7-14. Try to find one with zero, or at least the lowest middle number. Your efforts will help control the excessive amounts of phosphorous found in our waterways.
