End of season date ?Comment:End of season indicates to the model that the crop is removed from the field. If an End of Season operation is not present, then the model assumes that the crop is left growing. End of season should be used for all annual crops. For certain perennial crops like hay and pasture, End of Season operations may be absent from the crop schedule. |
Fertilizer amount (commercial) | Fertilizer amount (manure) |
Fertilizer category ?Comment:Solid manure. |
Fertilizer composition (commercial) ?Comment:These fields indicate the N and P composition. These fields are pre-filled based on the fertilizer type selected, but can be modified if needed. |
Fertilizer depth | Fertilizer total N concentration (manure) | Fertilizer total P concentration (manure) |
Fertilizer type ?Comment:Cattle. |
Field (area of interest) ?Comment:A field plot located in the eastern portion of the Goose Branch microwatershed of the North Bosque watershed. |
Field area |
Forest buffer width ?Comment:Optional variable included in the Forest buffer alternative scenario (Run). The buffer is subtracted from the field area and situated across the entire slope at the downslope edge. Buffer area is computed in the model from its width and field dimensions. |
Grass strip vegetation ?Comment:Optional variable included in the Filter strip alternative scenario (Run). The filter strip vegetation is assumed to be switchgrass. |
Grass strip width ?Comment:Optional variable included in the Filter strip alternative scenario (Run). The strip is subtracted from the field area and situated across the entire slope at the downslope edge. Strip area is computed in the model from its width and field dimensions. |
Harvest date |
Moisture content (manure) ?Comment:For manure fertilizer, this is the percentage, by weight, of moisture content in the manure. Typical values for each manure type are provided, but can be modified by the user. |
Plant method ?Comment:Not reported. |
Planting date ?Comment:Not reported. Fall for wheat, spring for sorghum. |
Rotation year ?Comment:The rotation year indicates the sequence of the crop within the crop schedule, it does not represent the calendar year. |
Seed amount | Soil organic matter |
Soil P ?Comment:It was assumed, based on the agricultural practices in Erath County, that the initial soil P in the top 15 cm of soil depth was 150 ppm. |
Soil P test ?Comment:Best professional judgement used in place of? |
Tillage ?Comment:Provided for the verification period (1997-1999): chisel plow, plow. |

End of season date ?Comment:End of season indicates to the model that the crop is removed from the field. If an End of Season operation is not present, then the model assumes that the crop is left growing. End of season should be used for all annual crops. For certain perennial crops like hay and pasture, End of Season operations may be absent from the crop schedule. |
Fertilizer amount (commercial) | Fertilizer amount (manure) |
Fertilizer category ?Comment:Solid manure. |
Fertilizer composition (commercial) ?Comment:These fields indicate the N and P composition. These fields are pre-filled based on the fertilizer type selected, but can be modified if needed. |
Fertilizer depth | Fertilizer total N concentration (manure) | Fertilizer total P concentration (manure) |
Fertilizer type ?Comment:Cattle. |
Field (area of interest) ?Comment:A field plot located in the eastern portion of the Goose Branch microwatershed of the North Bosque watershed. |
Field area |
Forest buffer width ?Comment:Optional variable included in the Forest buffer alternative scenario (Run). The buffer is subtracted from the field area and situated across the entire slope at the downslope edge. Buffer area is computed in the model from its width and field dimensions. |
Grass strip vegetation ?Comment:Optional variable included in the Filter strip alternative scenario (Run). The filter strip vegetation is assumed to be switchgrass. |
Grass strip width ?Comment:Optional variable included in the Filter strip alternative scenario (Run). The strip is subtracted from the field area and situated across the entire slope at the downslope edge. Strip area is computed in the model from its width and field dimensions. |
Harvest date |
Moisture content (manure) ?Comment:For manure fertilizer, this is the percentage, by weight, of moisture content in the manure. Typical values for each manure type are provided, but can be modified by the user. |
Plant method ?Comment:Not reported. |
Planting date ?Comment:Not reported. Fall for wheat, spring for sorghum. |
