Indasitiri yezvekurima inzvimbo yekuvandudza kwesainzi uye tekinoroji.Mapurazi emazuva ano nemamwe mabasa okurima akasiyana zvikuru neekare.
Nyanzvi mune iyi indasitiri vanowanzo gadzirira kutora matekinoroji matsva nekuda kwezvikonzero zvakasiyana.Tekinoroji inogona kubatsira kuita kuti mashandiro aite zvakanaka, zvichiita kuti varimi vaite zvakawanda munguva shoma.
Sezvo huwandu hwevanhu huri kuwedzera, kugadzirwa kwezvokudya kunoramba kuchiwedzera, zvose zvinoenderana nefetereza yemakemikari.
Chinangwa chikuru ndechekuti varimi vadzikise huwandu hwefetereza yavanoshandisa ivo vachiwedzera goho.
Ramba uchifunga kuti zvimwe zvirimwa zvinoda fetereza yakawanda segorosi.
Fetereza chinhu chipi nechipi chinowedzerwa muvhu kuti chisimudzire kukura kwezvirimwa uye chave chikamu chakakosha mukugadzirwa kwekurima, kunyanya neindasitiri.Kune marudzi akawanda emafetereza, anosanganisira mamineral, organic uye mafetereza ekumaindasitiri.Zvizhinji zvine zvinhu zvitatu zvakakosha zvinovaka muviri: nitrogen, phosphorus uye potassium.
Zvinosuruvarisa, haisi yose nitrogen inosvika zvirimwa pachazvo.Muchokwadi, 50% chete yenitrogen mufetireza inoshandiswa nemiti paminda yekurima.
Nitrogen kurasikirwa idambudziko rezvakatipoteredza sezvo ichipinda mumhepo uye miviri yemvura yakaita semadziva, nzizi, hova nemakungwa.Zvakakoshawo kuziva kuti mukurima kwemazuva ano, nitrogen fertilizer inowanzoshandiswa.
Mamwe ma microorganisms ari muvhu anogona kushandura nitrogen kuita mamwe magasi ane nitrogen anonzi greenhouse gases (GHGs).Kuwedzera mazinga ekubuda kwegreenhouse gasi mumhepo kunotungamira mukudziya kwepasi uye, pakupedzisira, shanduko yemamiriro ekunze.Mukuwedzera, nitrous oxide (gasi rinopisa) rinoshanda kupfuura carbon dioxide.
Zvinhu zvose izvi zvinogona kukanganisa zvakatipoteredza.Nitrogen-ine fetiraiza munondo unocheka kaviri: iwo akakosha pakukura kwezvirimwa, asi yakawandisa nitrogen inogona kuburitswa mumhepo uye inokonzera huwandu hwemhedzisiro yakaipa pahupenyu hwevanhu nemhuka.
Sezvo vatengi vazhinji vachitora mararamiro akasvibira, makambani kumaindasitiri ese ari kutarisa kutora maitiro akatsiga kuita kuti aite zvakanaka nharaunda.
Varimi vachakwanisa kuderedza huwandu hwefetireza yemakemikari inoshandiswa mukurima zvirimwa pasina kukanganisa goho.
Varimi vanokwanisa kugadzirisa fetiraiza yavo zvichienderana nezvinodiwa nembesa dzavo uye mibairo yavanoda kuwana.
