Soil nutrients after brush burning: Tests with greenhouse plants show that burning increases supply of nitrogen, phosphorus, and sulfur in soil

Abstract

A program of brushland conversion from chaparral cover to the more useful cover of grass and clover has been in progress in California for several years. In many situations, prescribed burning is used to accelerate brush disposal. Because of the hazards involved, prescribed burning is performed under specified conditions of temperature, humidity, season of the year, and with approved fire-crew supervision.
