Abstract
|
|
|
Determination of the pH value and analyses of the available phosphorus of some soils under the forest and grassland Kwang-nung have been examined to study the relationship between the soil pH and available phosphorus. The results might be summarized as follows:
1) The available phosphorus decrease steadily as the pH goes up to 5.2. However, at the pH 5.2∼6.3, it shows an increase and decreases again as the rise above pH 6.3.
2) There is a significant difference in the amounts of the soil phosphate among the areas sampled.
3) The statistical analysis of the data obtained shows that soil phosphate is limiting factor governing the distribution of natural vegetal pattern.
