NRCS Idaho ikufuna kupatsa malo ambiri a SNOTEL masensa owunikira chinyezi cha nthaka

Mapulani okonzekera malo onse oyezera chinyezi cha chipale chofewa ku Idaho kuti ayesere chinyezi cha nthaka angathandize oneneratu za madzi ndi alimi.
Bungwe la USDA's Natural Resources Conservation Service lili ndi malo 118 a SNOTEL omwe amayesa okha kuchuluka kwa mvula, kuchuluka kwa madzi a chipale chofewa, kuya kwa chipale chofewa ndi kutentha kwa mpweya. Ena asanu ndi awiri ndi osachita zambiri, ndipo amayesa mitundu yochepa.
Chinyezi cha nthaka chimakhudza momwe madzi amayendera bwino chifukwa madzi amalowa pansi pamene pakufunika asanapite ku mitsinje ndi m'madamu.
Hafu ya malo onse osungiramo zinthu a SNOTEL m'boma ili ndi zoyezera chinyezi cha nthaka kapena ma probe, omwe amatsatira kutentha ndi kuchuluka kwa madzi m'madzi akuya angapo.
Deta "imatithandiza kumvetsetsa bwino ndikuwongolera madzi" ndikudziwitsa "mbiri yofunika kwambiri ya deta yomwe tikuyembekeza kuti idzakhala yothandiza kwambiri pamene tikusonkhanitsa deta yambiri," adatero Danny Tappa, woyang'anira kafukufuku wa chipale chofewa wa NRCS Idaho ku Boise.
Iye anatero kuti kukonza malo onse a SNOTEL m'boma kuti ayesere chinyezi cha nthaka ndi chinthu chofunika kwambiri kwa nthawi yayitali.
Tappa anati nthawi ya ntchitoyi imadalira ndalama zomwe zaperekedwa. Kukhazikitsa masiteshoni atsopano kapena masensa, kukweza njira zolumikizirana kuti zikhale zamafoni ndi ukadaulo wa satelayiti, komanso kukonza zinthu zonse kwakhala zofunikira kwambiri posachedwapa.
"Timazindikira kuti chinyezi cha nthaka ndi gawo lofunika kwambiri pa bajeti ya madzi, komanso kuyenda kwa madzi kumapeto," adatero.
"Tikudziwa kuti pali madera ena omwe kuyanjana kwa chinyezi cha nthaka ndi kuyenda kwa madzi ndikofunikira kwambiri," adatero Tappa.
Dongosolo la SNOTEL ku Idaho lingapindule ngati malo onse ochitira masewera olimbitsa thupi ali ndi zida zoyeretsera nthaka, anatero Shawn Nield, wasayansi wa nthaka m'boma la NRCS. Ndibwino kuti ogwira ntchito yofufuza chipale chofewa akhale ndi katswiri wodziwa bwino ntchito yosamalira dongosololi komanso mbiri yake ya deta.
Kulondola kwa momwe zinthu zilili pa nthawi ya madzi kwawonjezeka ndi pafupifupi 8% pomwe zida zoyezera chinyezi cha nthaka zidagwiritsidwa ntchito, adatero, potchula kafukufuku wochitidwa ndi akatswiri a zamadzi ndi ogwira ntchito ku yunivesite ku Utah, Idaho ndi Oregon.
Podziwa momwe nthaka imakhutitsidwira imapindulira alimi ndi ena, Nield anati "Nthawi zambiri, timamva za alimi omwe amagwiritsa ntchito zoyezera chinyezi cha nthaka kuti azitha kuyendetsa bwino madzi othirira," adatero. Ubwino womwe ungapezeke ndi wochepa poyendetsa mapampu - motero kugwiritsa ntchito magetsi ndi madzi ochepa - kufananiza kuchuluka kwa zinthu zomwe zimafunikira pakukula kwa mbewu, ndikuchepetsa chiopsezo choti zida zaulimi zigwidwe m'matope.
