Alternative solution to treat the problem of hypoxia does not exist due to the variation of the contributing factors among locations. The dead zone of the Gulf of Mexico can be reduced by

lessening the nitrogen runoff from the farms

. If the fertilizer is applied efficiently and precisely, it will reduce the excessive nutrient amount from being washed out.

crop rotation


conservation tillage

techniques, soil erosion can be prevented. Also, technique like wetland restoration and preservation can act as a savior.
