Abstract
The trees grown in solution cultures, while tolerating extremely low or high pH values in their nutrient medium, made greater and healthier growth in acid than in alkaline solns. The conception that these trees grow well at pH values as high as 8.5 or higher is based on faulty methods of preparing soil samples for pH detns. The pH of soils depends upon the soil moisture content as well as on other factors and may vary considerably according to the soil moisture present at the time the detn. is made. Several sources of N were used together with various pH ranges in soln. cultures. Equally important are the soil cultures in which the pH of the soil and its relation to the source of N has been detd.[long dash]Although trees in California are grown in the field under an irrigated agriculture, they are, growing primarily in an acid rather than in alkaline medium, and the acidity of the medium is far greater than has previously been assumed.
