Sand tsis muaj muaj peev xwm pauv cations vim nws tsis muaj hluav taws xob. Qhov no txhais tau hais tias cov av xuab zeb xws li podzolic topsoils muaj CEC tsawg heev, tab sis qhov no tuaj yeem txhim kho los ntawm kev ntxiv cov organic teeb meem.
Dab tsi yog qhov sib pauv cation tsawg?
Soil cation exchange peev (CEC) yog tus lej tseem ceeb rau cov yam ntxwv tseem ceeb hauv av. … Yog tias tus lej CEC tsawg, tsis muaj ntau lub molecules tuaj yeem khi (hloov) rau qhov chaw particle Yog tias tus lej siab, ntau cov molecules tuaj yeem khi rau qhov particle qhov chaw.
Vim li cas kaolinite muaj CEC qis?
Ntawm 10-30 cm qhov tob, txawm li cas los xij, cov ntsiab lus organic txo qis thiab cov av kuj tseem muaj av nplaum tsawg, thiab yog li CEC qis. CEC nce nyob rau hauv subsoil txheej vim qhov nce hauv av nplaum cov ntsiab lus. Cov av nplaum tseem ceeb hauv cov av no yog kaolinite, txawm li cas los xij, yog li CEC qhov tseem ceeb nyob qis dua piv rau ntau cov av nplaum.
Puas cov organic muaj CEC qis?
Organic teeb meem muaj siab CEC xws li 250 txog 400 meq / 100 g (Moore 1998). Vim tias CEC siab dua feem ntau qhia tias muaj av nplaum ntau dua thiab cov khoom organic muaj nyob hauv cov av, cov av CEC siab feem ntau muaj peev xwm tuav dej ntau dua li cov av CEC tsawg.
Dab tsi yog qhov kev sib pauv cation siab?
Defining Cation Exchange Capacity
CEC siab dua, the siab dua tus nqi tsis zoo thiab ntau dua cations uas tuaj yeem tuav tau CEC ntsuas hauv millequivalents ib 100 grams av (meq / 100 g). Ib meq yog tus naj npawb ntawm ions uas tag nrho ib qho tshwj xeeb ntawm cov nqi hluav taws xob.
