Uzroci erozije tla<\/strong><\/h2>\n

Erozija tla je odno\u0161enje povr\u0161inskog dijela tla pod utjecajem prirodnih sila vode, vjetra ili poljoprivrednih djelatnosti, poput obrade tla (dubina, smjer i vrijeme oranja, vrsta mehanizacije za obradu tla i broj prolaza) i kr\u010denje vegetacije. Kr\u010denjem vegetacije uklanjaju se za\u0161tita bilja i korijenje potrebnih za odr\u017eavanje tla na mjestu. U osnovi, \u0161to je tlo izlo\u017eenije ili ja\u010de obra\u0111ivano, to je vjerojatnije da \u0107e erodirati tijekom ki\u0161a ili oluja. Vjetar pak mo\u017ee o\u0161tetiti mlade sadnice, te otpuhati povr\u0161inski sloja tla i izlo\u017eiti sadnice ili ih ukopati preduboko. Erozija tla, bilo vodom, vjetrom ili obradom, uklju\u010duje tri razli\u010dita djelovanja \u2013 odvajanje tla, kretanje i talo\u017eenje. Erozija mo\u017ee biti spor proces koji se odvija relativno nezapa\u017eeno, \u0161to uzrokuje ozbiljan gubitak povr\u0161inskog sloja tla. Problem zbijenosti tla, niske koli\u010dine organske tvari, gubitka strukture tla, lo\u0161e unutarnje drena\u017ee, salinizacije i kiselosti tla, druga su ozbiljna stanja degradacije tla koja mogu ubrzati proces erozije tla.<\/p>\n

Erozija tla smanjuje produktivnost poljoprivrednih povr\u0161ina, te doprinosi one\u010di\u0161\u0107enju susjednih vodotoka, mo\u010dvara i jezera. Kada voda odnese poljoprivredno tlo, ona sa sobom nosi i zaga\u0111iva\u010de poput gnojiva i pesticida. To otjecanje mo\u017ee prouzro\u010diti one\u010di\u0161\u0107enje vode, koja zatim zaga\u0111uje pitku vodu i ometa ekosustav jezera i mo\u010dvara. To negativno utje\u010de i na ribe i divlja\u010d, kojima su te vode nu\u017ene za ishranu i stani\u0161te.<\/p>\n

Kako smanjiti eroziju tla?<\/strong><\/h2>\n

Erozija tla vodom, vjetrom i obradom mo\u017ee se smanjiti raznim mjerama za\u0161tite tla. Obrada tla, prakse uzgoja biljaka, kao i praksa upravljanja zemlji\u0161tem, izravno utje\u010du na cjelokupni problem erozije tla i rje\u0161enja na poljoprivrednom gospodarstvu. Kada plodored ili promjena prakse obrade tla nisu dovoljne za kontrolu erozije, potrebni su kombinirani pristupi ili ekstremnije mjere, poput konturiranog oranja (oranje du\u017e krivulje nagnutosti terena), sadnja u pruge ili terasiranje. U ozbiljnijim slu\u010dajevima gdje dolazi do koncentriranog otjecanja, potrebno je uklju\u010diti i strukturne kontrole kao dio cjelokupnog rje\u0161enja – travnate vodne putove, odvodne cijevi, bazene za kontrolu vode i sedimenata. Jedan od najboljih na\u010dina za spre\u010davanje erozije tla je pove\u0107anje vegetacije, sadnja usjeva koji pru\u017eaju potpuni za\u0161titni prekriva\u010d tijekom ve\u0107eg dijela godine (npr djetelina ili zimski pokrovni usjevi), ili razne biljke i drve\u0107e.<\/p>\n

U posljednjih 150 godina nestala je polovica poljoprivrednog tla na planeti. Osim erozije, na kvalitetu tla utje\u010du i drugi aspekti poljoprivrede, koji uklju\u010duju zbijenost, gubitak strukture tla, smanjenje hranjivih tvari i salinitet tla. To su stvarni i ponekad vrlo ozbiljni problemi. Erozija tla klju\u010dni je izazov u poljoprivredi diljem svijeta. Mnogi poljoprivrednici ve\u0107 su napravili zna\u010dajan napredak u rje\u0161avanju problema erozije tla na svojim poljoprivrednim gospodarstvima.<\/p>\n

Zdravlje tla je primarna briga za poljoprivrednike i globalnu zajednicu \u010dija egzistencija ovisi o dobro upravljanoj poljoprivredi. Porast ekstremnih vremenskih uvjeta uslijed klimatskih promjena u budu\u0107nosti \u0107e pove\u0107ati ve\u0107 postoje\u0107u eroziju vodom i vjetrom i dovesti do novih briga, te stoga poljoprivredno zemlji\u0161te mora biti za\u0161ti\u0107eno koliko god je to mogu\u0107e, s posebnom pa\u017enjom na rizi\u010dnije situacije koje ga \u010dine podlo\u017enijim eroziji.<\/p>\n"},"excerpt":{"rendered":"
