Also covered are climate and water management planning considerations. These courses are also a requirement of the Certified Conservation Planner curriculum.

The courses have two separate course titles and separate exams in AgLearn, be sure to register for both and take the exams to receive a certificate of completion for both courses. 

 

National Agricultural Statistics Service (NASS)

Census of AgricultureCounty specific data (examples include acres and sales by crop type, number and sales by livestock type and types of operators and operations) can be found by selecting “Find data by: state and county”  or querying “Data Search Tools: Quick Stats”   This data is useful to help determine the types of agricultural operations that exist within a county or other geographic work area. 

CropScape – Cropland Data Layer
Layer developed by USDA NASS in cooperation with NASA.  Map showing crop history of areas going back to 1997.  Also evaluation of how many years an area has been in specific crops.  Useful for remotely determining crop and rotations.  Area of interest can be defined or uploaded as an ESRI shapefile.  Data can be exported as .tif and KML files

VegScape – Vegetation Condition Explorer
Layer developed by USDA NASS in cooperation with NASA.  Map showing crop condition monitoring system.  Integrates soil moisture, temperature, etc.   Some of the maps and legend abbreviations are confusing.  Here is a link to a presentation of what information is available.
