In his early years in the 1820s Donalson had the management of large farms, and extensive estates, such as those of Loudon Castle in Ayrshire, and Donnington Park in Leicestershire, both in Scotland and England.

[5] In the title pages of his chief writings, Donaldson is described as "Professor of Botany" and "Government Land Drainage Survey.

[2] Donaldson was presented to the Charterhouse by the Prince Consort in August 1855, and died a poor brother there on 22 March 1876, leaving a will in favour of Elizabeth Saine, a widow.

[6] Donaldson is described by Fussell (1983) as "another of these Victorian goliaths whose output was large, and... was intimate with the writings of all his bucolic and farming literary ancestors.

His 1860 British Agriculture : Cultivation of Land, Management of Crops, Economy of Animals, is an elaborate compilation dedicated to the Duke of Argyll.
