Test
your knowledge answers:
|
|
1. Fertilizer
should never be used on sidewalks. Fertilizers are
a major source of water pollution in Maryland. From
your sidewalk, it is quickly flushed to surface and
groundwater sources.
|
2. Under most
circumstances, fertilizer should be applied in the
fall.
|
|
3. Pet wastes
should not be composted in the backyard compost
pile. Temperatures in compost piles do not get high
enough to ensure that disease-carrying bacteria and
viruses are killed.
|
4. No. Lime should
only be added if a soil test recommends raising the
pH, and then only at the recommended rate.
|
|
5. Yes. These
seemingly harmless products can be extremely
corrosive or caustic, and proper care must be taken
during handling. They can be a major source of
water pollution. Be sure to follow the instructions
for use and disposal.
|
6. Use plants that
are native to this region. They require less
fertilizer and pesticides, and may be able to
withstand drought better.
|
|
7. Plant ground
covers on slopes where mowing is difficult. Build
retaining walls to hold soil in place on steep
slopes.
|
8. Integrated Pest
Management (IPM) is a decision-making process that
evaluates all viable options for pest control,
favoring options with the least impact on human
health and the environment.
|
|
9. No. Many
insects, such as ladybug beetles and fireflies,
benefit the landscape by eating other "pest"
insects that damage plants.
