## Soil Based on data collected by ISRIC – World Soil Information is available in FieldAgent to help with understanding and making decisions on prescriptions and planting. 1. Select the field that soil data is needed. 2. Click on the Soil icon in the menu on the left side of the screen, as shown in Figure 88.

3. Select the depth of the soil from the drop-down list, as shown in Figure 89.

4. The details of the soil makeup display, as shown in Figure 90. The value of the soil for this location displays for 0 CM depth.

* **Sand:** Percentage of sand in the soil. * **Silt:** Percentage of silt in the soil. * **Clay:** Percentage of clay in the soil. * **Cation Exchange Capacity:** A measure of the soil’s ability to hold positively charged ions. It is an important soil property influencing soil structure stability, nutrient availability, soil pH, and the soil’s reaction to fertilizers and other ameliorants. * **Soil pH in H2O:** A mixture, by weight, of one part soil to one part distilled H2O to determine soil acidity. * **Bulk Density:** Weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. * **Coarse Fragments:** Particles larger than 2 mm and smaller than 25 cm in diameter. * **Nitrogen:** The most abundant element in the atmosphere and is usually the most limiting crop nutrient. * **Organic Carbon Content:** Tends to be concentrated in the topsoil. Topsoil ranges from 0.5 – 3.0 percent organic carbon for most upland soils. Soils with less than 0.5 percent organic carbon are mostly limited to desert areas. Soils containing greater than 12 – 18 percent organic carbon are generally classified as organic soils. * **Organic Carbon Density:** A percentage of the topsoil 0 – 10 cm. * **Organic Carbon Stocks:** The quantity of carbon contained in a reservoir or system which has the capacity to accumulate or release carbon. ## Field Activities Field Activities allows the user to document activity in the field-based on seasons. This activity can be planting or irrigation. The information leads directly to how and when the notifications are triggered. ### Creating an Activity 1.
