During the growing season, a balanced fertilizer, which has been diluted to 1/4 strength, can be added to the water for each watering. (A balanced fertilizer is one that has roughly equal proportions of Nitrogen, Phosphorous, and Potassium. A 10-10-10 fertilizer diluted to 1/4 strength is ideal.)
Q: How many animals are used each year in U.S. laboratories for biomedical research?A: It is estimated that more than 25 million vertebrate animals (animals with a skeleton made of bone) are used annually in research, testing, and education in the United States.
These are national estimates; the figures may vary from state to state. 1  Approximately 6.5 million companion animals enter U.S. animal shelters nationwide every year. 2  Each year, approximately 1.5 million shelter animals are euthanized (670,000 dogs and 860,000 cats).
