If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.
<h3>What is a manure?</h3>
A manure is that which is used to improve the fertility of the soil. It is composed of the nutrients that are required by the soil. We know that each pig produces 30 liters of manure each day, and the average feedlot holds 900 pigs. Hence, each day, 30 * 900 = 27000 litres of manure is produced.
Within a period of 30 days, a total of 27000 litres of manure * 30 = 810,000 litres of manure is produced. If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.
