Then , one year , I decided to take this splendid advice and test my soil .
And it was only when I saw the results that I realized that I had been wasting money by tot up a cluster of nutrient to my dirt that was n’t needed .
Not only was I wasting money , but I was unwittingly harming the environment because a circumstances of that extra clobber was being washed off into local weewee resource .
