MINOR, BUT FUNDAMENTAL ISSUE: Soil type inconsistency in ORCHIDEE-CN-P

The phosphorus model needs soil type specific parameters. Therefore, a new input routine is introduced which reads in USDA soil orders. According to the soil order the parameter values are set for each grid box.

The problem is that ORCHIDEE already reads in fields of soil texture classes which were originally derived from soil orders. According to the soil texture classes, parameter related to soil hydrology are set. As the original data cannot be found anymore, ORCHIDEE will run with two independent sets of soil order specific parameters. Thereby inconsistencies between the phosphorus related parameters and the the hydrology related parameters can be introduced. The practice of reading in soil texture classes instead of soil orders is in general problematic. The ORCHIDEE project members are informed but they seem not to care about this.
