Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

pastĭnātum, i, n., v. pastino fin.

pastĭno, āvi, ātum, 1, v. a. [pastinum], to dig and trench the ground, to prepare the ground, for the planting of vines: pastinandi agri rationem tradere, Col. 3, 13, 6; 11, 3, 9: solum, Plin. 17, 21, 35, § 159: vineas, id. 18, 26, 65, § 240: pastinatae vineae, id. 14, 1, 3, § 14; Vulg. Marc. 12, 1.
Hence, pastĭnātum, i, n. (sc. solum), ground dug and trenched; ground prepared for planting the vine, Col. 3, 13, 7: vineam in pastinato serere, Plin. 17, 22, 35, § 172; Col. 3, 3, 11: umidum pastinatum, id. 3, 16, 1.
