this is the second respose

 I found an interesting article that deals with a soil breakthrough helping growers. First, the issue here is that growers and farmers might have been over fertilizing their crops for almost their entire life. But Richard Haney, A USDA Agricultural Research Service soil scientist in Temple, Texas, stands by with a microwave plasma to maybe stop this over fertilizing. This microwave plasma measures minerals at the molecular level, which have helped growers assess their soil organic matter and plant-available soil nutrients and also gives producers insight into the effectiveness of their efforts to improve soil health. Like i said earlier that the growers might be over fertilizing their crops, i really just meant that their are! Especially with nitrogen. Haney has devised the first method to measure organic nitrogen and phosphate in soil that will be available for a plant to utilize. Prior test besides, Haney’s method, have missed plant-available organic phosphate and nitrogen, leading producers to overestimate the amount of supplemental fertilizer necessary to raise a crop.
