Arenosols comprise deep sandy soils. This includes soils in residual sands after in situ weathering of usually quartz-rich sediments or rock, and soils in recently deposited sands such as dunes in deserts and beach lands. Corresponding soils in other classification systems include Psamments (United States of America), Sols minéraux bruts and Sols peu évolués (France), Arenic Rudosols/Tenosols (Australia), Psammozems (Russia) and Neossolos (Brazil).

Plectranthus esculentus, with English common names kaffir potato, and Livingstone potato, is a species of plant in the dicot family Lamiaceae. It is indigenous to Africa, where it is grown for its edible tubers. (https://africanorphancrops.org/plectranthus-esculentus/)
The liquid portion of malted grain. It is a solution of malt sugar and other soluble extracts from malted mash. (Tacon, A.G.J., 1987.

Organisms permanently found at the sea surface, limited to the surface by their own buoyancy, often or typically extending into the air, and subject to wind drift. (Johnson, R.K., B.J. Zahuranec, D. Boltovskoy and A.C. Pierrot-Bults. 2000. Glossary of Pelagic Biogeographic Terms. https://scor-int.org/Working_Groups/WG93_Glossary.pdf)
In fisheries, biological stocks are subpopulations of a species inhabiting a particular geographic area, having similar biological characteristics (e.g. growth, reproduction, mortality) and negligible genetic mixing with other adjacent subpopulations of the same species. (FAO, 2021. FIRMS stocks and fisheries inventory templates, workflow, and dissemination. https://www.fao.org/3/cb6134en/cb6134en.pdf)
Ploughing (tillage): mechanical cultivation of agricultural soils by the plough to different depths (20 – 30cm) deep, creating arable land. (European Soil Data Centre (ESDAC) Glossary of soil terms https://esdac.jrc.ec.europa.eu/ESDB_Archive/Glossary/Glossary.pdf)
