Soil properties: Nutrient holding capacity

Description

Nutrient holding capacity describes the ability and quantity of nutrients a soil can retain. Higher nutrient holding capacity allows for greater nutrient retention upon fertilization, less fertilizer applications, and greater nutrient availability to plants. Representative cation exchange capacity at pH 7 (CEC7) and, for soils with variable surface charge, effective cation exchange capacity (ECEC) data from the SSURGO database were used to estimate nutrient holding capacity classes based on the five-number-summary (Low = 0-15, Moderate > 15-30, High > 30-45, Very High > 45 cmolc/kg).

808 Planner

The Oʻahu Resource Conservation and Development Council (ORCD) in collaboration with the City and County of Honolulu’s Office of Economic Revitalization (CCH-OER) present practical strategies for the agricultural and forestry sectors to adapt to climate change and extreme weather events.

We’ve developed the “808 Planner” tool to fulfill a part of our shared mission. This interactive map allows users to draw an area of interest and quickly obtain a summary of environmental characteristics, such as: administrative boundaries, climate, elevation, hazards, land use, and soils.

This tool aims to assist:

  • Agricultural Extension Services
  • Farmers
  • Landowners
  • Researchers
  • The General Public
