If pesticides and fertilizers must be used, how can its environmental impacts be reduced?

Answer 1

forget it
pesticides and herbicides are wrong all the time as well as fertilizers

there are no exceptions
they contaminate ground waters ,raise the PH and affect human childbirth very negatively.
And desertification is usually the final product when the soil has been killed by agro chemicals and heavy equipment

Alternative Farming Methods ,that are sustainable and autosufficient ,using proved organic methods are the answer

there are hundreds of ways to get rid of pests either by design (diversity)or organic methods of pest control

herbicides are rediculous
just a mulch cover gets rid of weeds and produces compost this also makes fertilizers obsolete

MULCH
what you do is to cover the ground with mulch which is the same principal as compost but it includes the whole garden surface
the top part of the soil where the topsoil is being produced houses a world or microbiotic life.

Mulch is organic material green or dry that covers the ground,the thicker the better the composting process will turn it in to black topsoil

the humidity is preserved underneath and promotes the devellopment of worms,who airate the soil (their exists no better compost than their excrements)and a variety of micro biotic life which together with the mulch produce more topsoil.

the mulch also keeps the ground temperature even and guards against the impact of the rain ,which would other wise brings salt to the surfave if on unprotected land

Mulch also prevents the soil from drying out because of the sun and, lay it open to wind erosian.

and it turn out the lights for any weeds that want to come up

do not use chemicals because the water will wash them into the ground and if enough people did that, you would be guilty of helping to contaminate subteranean water suplies that other people could be pumping up to drink,

ALTERNATIVE FARMING
read up on Organic Farming and Permaculture
A lot of hardcore Intelligent farmers are changing for sustainable farming
instead of the quick 3 to 5 years of intense monocultures that kill the ground and then live with the consequences

and dont talk dirty again,mentioning pestecides and herbicides , there are childen on this show

NOTE ON ORGANIC PEST CONTROL

Just a few examples of organic pest control and there are thousands

In Mexico we got a sort of small lizard that lives on the wall ,and sit near the lamps ,and eat mosquitos all night,

in the mango orchards we release laboratory bred wasps to attack and kill the caterpillars that go for the mangos

there are small chickens, called a silky or bantom or chaparito which are all small chickens that do not scratch ,but run after ,jumping and walking insects,they take care of about 70 percent of all garden pests.

feasants,guinyfowel,partridge will do the same work
iguanas kill grashoppers and all kinds of flying insects

birds we also dont kill
when the passion fruit is ripe ,a little black caterpiller comes and wants to destroy them,luckely a little finch type bird turns up and eats the black caterpillars.

In Mexico we have let mazacoas,which are, python type snakes in to the garden to take care of the rats.
In Africa we released mole snakes into the garden and field to combat the plagues of Norwegian rats that were destroying the fields

ant eaters and armadillos take care of leafcutting ants that can destroy a large tree in a week.and eat beatles and such

potbelly pigs and deer and normal pigs are good in an orchard because they eat fallen rotting fruit which breeds a lot of small flies.

in our water reservoirs we put fish to eat the mosquito larvas.

i have bred tree frogs from eggs and released them in the garden to eat mosquitos and horse flies.

Answer 2

Focusing the insecticide on its target is the best way. Recent innovations in ant and termite poisons utilize this strategy. Using a bait strategy, poison is coated in a tastey shell that the termites or ants deliver to the colony. This poisons the colony and takes care of the problem without a broadcast type of application that might harm desirable insects like earthworms, etc.

Also, you need to take the instructions with a little grain of salt. You will sometimes find that using a fourth of the recommended dose will kill 90% of the bugs you are concerned with. Depending on your goals, this may be more cost-effective.

Answer 3

Making sure only the arera needed to be sprayed is sprayed...no overspray in ditches, or other sources of water as these can pollute the water system. Only use WHEN necessary.

Answer 4

international warming is a group of bunk. there has been honestly no information it exist. that's in undemanding words a group of tree huggers attempting to grant more beneficial tree huggers and strengthen the fee of things and gas to 'save the international". Yeah correct!
