Ibn Bassal (1085 C.E.) was a Moor botanist in Toledo and Seville, Spain who wrote about cultivation. Basal wrote the treatise The Classification of Soils which divided soil fertility into ten classifications. He worked in the court of Al-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 (d.1349) of Almeria who based his treatise Kitāb Ibdā' al-malāha wa-inhā' al-rajāha fī usūl sinā'at al-filāha on Bassal's work.
