Soil properties: Acidity

Description

Soil pH is a measurement of the acidity or alkalinity of a soil, and it is an important soil property governing many biological, physical, and chemical processes, such as nutrient availability. Acidic pH levels (pH7.3) can lead to micronutrient (zinc, iron, copper) and phosphorus deficiencies. The “sweet” spot for most crops is in the neutral pH region (pH= 6 to 7). Representative pH values were compiled from the SSURGO database, and modified pH ranges from the NRCS Field Book for Describing and Sampling Soils were used to classify soil acidity and alkalinity (Acidic 7.3).

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
