Soil Physical and Chemical Properties NRCS New Jersey

2014-1-30  Soil “A”: 100% mineral soil material; bulk density = 1.33 g/cc. Soil “B”: 95% mineral soil material and 5% organic soil material; bulk density = 1.26 g/cc. The difference in bulk density relates to a difference in “particle density” of mineral soil material versus organic soil material.

[Characteristics of artificial grassland plant

Soil microbial biomass carbon significantly positively correlated with soil moisture and organic matter contents, but negatively correlated with soil bulk density. Soil organic carbon content had a "V" type change, which was consistent with the change pattern of soil moisture content, and decreased with increasing soil bulk density.

We showed the capacity of a CNN to be trained in a multi-task setting to simultaneously predict six soil properties in one model (OC, CEC, clay, sand, pH, total N). Compared with conventional methods such as PLS regression and Cubist regression tree, the CNN performed significantly better, especially the multi-tasking model.
