To carry out agricultural activities, with less environmental impact, it is important to know the soil composition, terrain, type of culture existing or to be implemented, agricultural machinery, the need for use of fertilizers, pesticides and other products of its kind, addition of water and forest resources. Among the many problems that agriculture because of the nature the most debated is the use of herbicides, pesticides, fungicides and other pesticides called - see definition of ANVISA earlier this leaves. Even though the problems caused, the use of these products is widespread. Its expansion is due to the rapid advancement of agricultural technology and the need to achieve greater productivity, which makes its control or extinguishment. Pesticides are also transported by surface water to the river beds, seepage into groundwater, contamination-ing them, and penetrate the food that will be eaten, not to mention the possibility of being taken by the wind to distant areas or remain in the soil for many years contaminate future crops. See the text "Wastes and health services contaminate soil" as this problem is common in Brazil. Your municipality is also in the list of contaminated? What is the justification for your answer? Table 4 Wastes and health services contaminate soil Contamination of soil is also a headache for 33% of Brazilian municipalities, and the highest proportions of occurrences were in the South and Southeast: 50% and 34%, respectively. The main causes of soil contamination were: use of fertilizers and pesticides (63%) and inadequate disposal of domestic sewage (60%). The water pollution caused by pesticide or fertilizer is a problem for 16.2% (901) of Brazilian municipalities. In the South Coastal Basin, 31% of municipalities reported water pollution by pesticides, and in the basins of the River Plate and the South Coast, the proportion was 19%. Already ground contamination by pesticides or fertilizers affects 20.7% of the 1,152 municipalities. Among states, the highest proportion of municipalities with contamination was found in Santa Catarina (56%) at the other end, Amapá and Piauí recorded the lowest proportion in the country, both with 2%.

Za obavljanje poljoprivrednih djelatnosti, s manje utjecaja na okoliš, važno je znati sastav tla, teren, tip kulture postojećih ili će se provoditi, poljoprivredni strojevi, potrebu za korištenjem umjetnih gnojiva, pesticida i ostalih proizvoda te vrste, Osim vode i šumskih resursa. Među mnogim problemima koji poljoprivredi zbog prirode najviše raspravljalo je korištenje herbicida, pesticida, fungicidi i drugih pesticida zove - pogledajte definiciju ANVISA ranije ovog lišća. Iako su problemi uzrokovani, korištenje tih proizvoda je široko rasprostranjena. Njegova ekspanzija je zbog brzog napretka poljoprivredne tehnologije i potrebe kako bi se postigla veća produktivnost, što čini svoju kontrolu ili gašenje. Pesticidi su prevozili površinske vode do rijeke kreveta, prodiranje u podzemne vode, onečišćenje-ing ih, i prodrijeti u hranu koja će se pojesti, a da ne spominjem mogućnost da se uzima od vjetra na udaljenim područjima ili ostati u tlu za mnogo godina zagaditi buduće usjeve. vidjeti tekst "Otpad i zdravstvene usluge zagaditi tlo", jer to je problem čest u Brazilu. Vaš Općina je također na popisu kontaminirana? Koje je opravdanje za odgovor? Tablica 4 Otpad i zdravstvene usluge zagaditi tlo Kontaminacija tla je glavobolja za 33% brazilskih općina, a najviše su proporcije pojava su u na jugu i jugoistoku: 50% i 34%, respektivno. Glavni uzroci onečišćenja tla su: uporaba umjetnih gnojiva i pesticida (63%) i neodgovarajuće odlaganje domaće kanalizacije (60%). Onečišćenje voda uzrokovano pesticida ili gnojiva je problem za 16,2% (901) brazilskih općina. U Južnoj priobalje Save, 31% općina izvijestio onečišćenja voda od strane pesticida, au slivova rijeke Plate i južnoj obali, udio bio 19%. Već onečišćenje tla pesticidima ili gnojivima utječe na 20,7% od 1.152 općina. Među državama, najveći udio općina s kontaminacije je pronađena u Santa Catarina (56%), na drugom kraju, Amapá i Piauí zabilježio najnižu udio u zemlji, oba s 2%. Izvor: www.ibge.gov.br/.
