At that time, it became the best-selling salsa record in history. This record was broken with the release of Cuenta Conmigo by Jerry Rivera in the 1990s. It has sold over three million copies worldwide, and almost all of its songs were hits at one time or another in various Latin American countries. With its rousing social commentary and unconventional sound, "Siembra" set the salsa world on fire and remains one of the most original and influential works in that genre. Among Siembra's tracks, Blades' masterpiece is still "Pedro Navaja," a song that he fashioned after Bertolt Brecht's "Threepenny Opera."
John Bush of Allmusic gave the album a five-star rating, praising the composition of the songs by Blades as well the arrangements by Colón. Bush emphasises the use of disco arrangements at the beginning of the first track, "Plástico", until Colón's band "slip into a devastating salsa groove". He also praised Blade's vocals, noting his high-tenor voice on "Buscando Guayaba" and tender tones on "Dime". David Wilson of Wilson & Alroy's also gave the album a five-star rating. He praised both the arrangements and the message of "Plástico", referring to "Dime" as "a beautiful love song".
