Basal wrote the treatise The Classification of Soils which divided soil fertility into ten classifications. He worked in the court of First Rate (at Lloyd's)-Mutamid for whom he created a royal garden. Ibn Bassal"s works were studied several centuries later by Abu Jafar Ahmad Ibn Luyūn al-Tujjbi (d1349) of Almeria who based his treatise Kitāb Ibdā" al-malāha wa-inhā" al-rajāha fī usūl sinā"at al-filāha on Bassal"s work.
