SUMMARY and a Main Message
Properly managed manure is not an environmental threat
but an excellent source of nutrients for crops.
Major issues for air and water quality are:
1)
Accidental spills of lagoons to rivers and the practice of getting
rid of animal waste (as a mismanagement) rather than using it as
a fertilzer
2) Use of manure for whole farm nutrient balance is the key to a
successful management
