Ivhu jabwanira

Ivhu - ndiro pamusoro paiva ivhu, iyo inozivikanwa wembereko - kukwanisa zvokudya zvinomera akura uye pave kuibvisa yavo. Agriculture hazvibviri pasina ivhu, nekuti yakura iri zhinji tsika inoshandiswa kugadzira zvokudya munhu uye kuti zvipfuwo zvokudya. Just sei anobatsira uye zvinovaka muviri zviri zvigadzirwa izvi zvinoenderana unhu uye mamiriro ezvinhu ivhu, kubva kutarisirwa kwaro, zvokudya uye kudiridza.

Most zvakabatsirawo zvokurima vanoonekwa dema ivhu akapfuma manyowa (manyowa). Pedogenesis - refu uye kunzwisisa chichiitwa, inova mugumisiro dzokuteerera mhepo uye okisijeni kuti mubereki dombo kuunganidza decomposing makemikari acho. Kana kunyange zvishomanana kusvibiswa ivhu, rinogona akadzorera kwenguva refu. Naizvozvo, unofanira kunyatsofunga uye kutarisira pasi zvakanaka.

Zvichakadai, nyika yekurima somugumisiro kusadiwa naye zvishoma nezvishoma vanorasikirwa wembereko nokukurumidza akaderedza uwandu manyowa. Man anotsvaka kuwana kubva ivhu napo, pasina kufungisisa nekusimba kudiwa alternation zvirimwa rimwe nomunda, "zororo" munda mushure imwe nguva "basa".

Kusvibiswa kukurwa kwevhu zvingaitika uye kwete anokonzerwa nomunhu, uye zvechigarire kukuvadza migumisiro mhepo uye mvura. Kazhinji, kukurwa kwevhu mumakumi emakore achangopfuura akarega kuva dambudziko okurima uye akawana kutambudzwa nezvinetso zvezvakatipoteredza.

Multiple kurapwa kunokonzera yakasviba ivhu. Kwemakore akawanda pamusoro chete nyika randomly kukura tsika yakasiyana, pasina kuita ivhu kuti anopa. Saka zvakarurama kuti ivhu ndaneta uye handichakwanisi kuita zvizere mabasa avo - zvitengeswa miti anodyiswa, Sefa tsvina uye zviwanikwa mvura.

Kuti ivhu vanofanira zvesayenzi uye rationally kuswedera anogona kuchengeta yakareba kushandiswa kwayo uye kurimwa kunatsiridza wembereko uye kubuda mariri zvokudya yakachena uye utano. Kuti aite izvi, unofanira kuita zvinoenderana chirimwa kutenderera, shandisa yepamusoro nokubudirira mune zvesayenzi, nyore uye basa purazi michini, sezvo shoma sezvo zvichiita kuti kushandisa mishonga, uye pachinzvimbo kushandisa nzira zvoutachiona kurima

Chemical fetiraiza uye kunyanya nitrate - chikuru tsime yakasviba ivhu. By pachavo, izvi zvinhu hazvisi kunokuvadza uye haagoni kuva tsime nomuchetura, nekusiyana - miriwo kuzvishandisa maumbirwo masero, chlorophyll inotungamirwa. Zvisinei, kuunganidza muvhu, nitrates kupinda chikafu, uye ipapo - mumuviri womunhu. Pane nitrates dzikava nitrites uye vanogona kupinda namakemikari maitiro pamwe chinoumba ropa - hemoglobin. Kubva dzichiri methemoglobinemia ichi - chirwere vane zviratidzo zviri wakaratidzwa kuderera kufurirwa, kuchinja noruvara ari mucous membranes uye ganda, paumbwe cardiac kana pulmonary chirwere.

Zvakafanana rinokosha pakusvibiswa mafuta ivhu. Hazvina kunyanya kwazvo pedo mikuru, gasi dzemapurisa, basa dzemapurisa, motokari anovaraidza. Uye munzvimbo idzodzo umo ari kugadzirwa mafuta, ayo kubudiswa, zvokufambisa, mafuta ivhu kusvibisa pamwero akapfuudza zvinobvumidzwa zvakapetwa kagumi.

Enderana kwetsvina iri landfill site dzakasiyana mavambo zvinoisa va neudhadha kushandisa nyika, anogona kukonzera zvakakomba kusvibiswa zvomumhepo, mvura, ichiwedzera yokufambisa uye chokwadi pamusoro kusingarapiki kurasikirwa zvinokosha zvicherwa muvhu.
