Kielelezo cha Eneo la Jani
Kielelezo cha Eneo la Jani (LAI) ni kiasi kisicho na vipimo kinachopima jumla ya eneo la upande mmoja wa majani kwa kila eneo la ardhi lililofunikwa na mwavuli. Kinatoa kiwango cha msongamano na muundo wa mwavuli: LAI = 0 kwa udongo tupu, LAI = 1 kwa mazao madogo, LAI = 3-6 kwa mwavuli mnene wa nafaka au nyasi, na LAI > 8 kwa misitu minene. LAI ni kigezo muhimu katika mifumo ya ukuaji wa mazao, makadirio ya uvukizaji maji, na hisi za mbali kwa sababu hudhibiti moja kwa moja ulaji wa mwanga, usanisinuru, na upotevu wa maji kutoka kwa mimea.
