Slash na ụgbọ ala

Slash-na-char bụ ihe ọzọ na slash-na-ọkụ nke nwere mmetụta dị nta na gburugburu ebe obibi. Ọ bụ omume ịcha biomass nke sitere n'igbu ahụ, kama ịgba ya ọkụ. N'ihi combustion ezughị ezu (pyrolysis) enwere ike iji unyi ihe fọdụrụnụ mee ihe dị ka biochar iji meziwanye ọmụmụ ala.^[1]^[2]

N'okwu a, enwere ike ịme unyi site n'ọtụtụ ụzọ dị iche iche. Nke kachasị mfe, nke a na-eji eme ihe n'akụkọ ihe mere eme na mmepụta unyi, gụnyere ọkụ ikpo ọkụ biomass site n'ịkụnye ya n'elu (nke a maara dị ka "ọkụ n'elu ala" ma ọ bụ "ọkụ nchekwa"[3] [4]) ma ọ bụ ihe mkpuchi ụwa n'elu ikpo osisi. , nwere oghere ndị etinyere n'ụzọ dabara adaba.

Ọ na-ebute n'ịmepụta biochar, nke a nwere ike ịgwakọta ya na biomass dị ka ihe ọkụkụ fọdụrụnụ, ihe oriri, ma ọ bụ nsị, ma lie ya n'ime ala iji mee ka e nwee terra preta.
