A plant that absorbs, translocates, or utilizes more of a specific nutrient than another plant under conditions of relatively low nutrient availability in the soil or growing media.
Industry:Earth science
A micromorphological feature derived from the parent rock that can be recognized by its rock structure and fabric.
Industry:Earth science
A graph of the flow rate, either surface or subsurface flow, with time.
Industry:Earth science
A soil temperature regime that has mean annual soil temperatures of 15°C or more but <22°C, and >5°C difference between mean summer and mean winter soil temperatures at 50 cm below the surface. Isothermic is the same except the summer and winter temperatures differ by <5°C.
Industry:Earth science
A method of overlaying large volumes of spatial data of different kinds. The data are referenced to a set of geographical coordinates and encoded in a form suitable for handling by a digital computer. Different data planes can be overlain, statistically analyzed, and used to make estimates of soil and land suitabilities.
Industry:Earth science
1. Conductivity of electricity through water or an extract of soil. Commonly used to estimate the soluble salt content in solution. 2. The ability of the soil to conduct electricity.
Industry:Earth science
A nonporphyrin metabolite secreted by certain microorganisms that forms a highly stable coordination compound with iron. There are two major types: catecholate and hydroxamate.
Industry:Earth science
A membrane, permeable to water and only very slightly permeable to gas when wet, through which water can escape from a soil sample in response to a pressure gradient.
