Black Earth was critically well received. Anders Sandvall of Metal Rules stated that "the album is brilliant and there are no bad songs on it."Allmusic's critic Alex Henderson wrote in his review that "Black Earth was a promising debut for Arch Enemy and is among the Swedish combo's more consistent and memorable efforts."
Ron Salden of Archaic Magazine said that Black Earth is a classic and praised the songs writing they "showcase a fresh mixture of death/thrash metal whilst the Amott brothers rip their guitars exquisitely to delightful bits of melody, harmony lines, guitar licks and solos." He praised "Bury Me an Angel" and comments that the songs "Eureka", "Transmigration Macabre" and "Fields of Desolation" still sounds fresh in these days. Chad Bowar of About.com said that the album sound "was raw, but the songs still were very catchy with solid guitar work from Michael and Christopher Amott".
About the songs, Metal Review's journalist Jason Jordan states: ""Dark Insanity" is arguably the best of the lot due to its fantastic riffs and leads, which Erlandsson backs up with a pummeling, and at times appropriately restrained, performance." He also comments that some songs like "Idolatress", "Cosmic Retribution", "Transmigration Macabre" and "Fields of Desolation" have praiseworthy characteristics too, though none quite match the verve of the openers. Jordan praised mainly the band members writing that "Black Earth is a solid outing of melodic death metal with each member in fine form" and that "the brothers Amott turn in excellent performances as the band's guitarists, Daniel Erlandsson provides backbone support from atop the throne, and Johan Liiva contributes his unique vocals to one of the better Arch Enemy efforts."
