Searching for soil indicators affecting on heterogeneity of black pine growth planted on the coastal forest

Abstract

Although, the forest regeneration on the embankment constructed after the 2011 Mega Tsunami in the Sendai Plain has been planned, poor growth of planted black pine has widely distributed. Some soil parameters were determined to detect controlling factors on the poor growth of black pine on the embankment. Results suggested that high soil electric conductivity accompanied by relatively acidic soil reaction seem to be responsible for the poor growth. The soil properties mainly derived from planting base substrates transported from the Sendai hill area were heterogenous in the planting base.
