University of Maryland Extension Resources for Horse Owners (EBR-51)

University of Maryland Extension (UME) is a non-formal education system within the College of Agriculture and Natural Resources (AGNR). All programs offered within Extension are based on research and data generated at land grant Universities and all programs are open to the general public. UME has equine educators and specialists in several counties in Maryland that offer a variety of programs and publications for horse owners.

Precision Soil Sampling Helps Farmers Target Nutrient Application (FS-1046)

Precision agriculture allows modern producers to manage within fields rather than managing the whole field.¹‚² By integrating global positioning systems (GPS), variable rate (VR) application equipment, and geographic information systems (GIS), farmers are allowed increased efficiency. However, prior to using VR equipment, accurate maps of yield-limiting factors must be created.³,⁴,⁵5 Nutrients in any field vary due to topography, soil properties and past management (manure application patterns, crop history, etc.). To account for this variability, farmers will need more than one soil sample in each field (Figure 1a). A more intensive sampling scheme must be performed, through either grid or zone sampling. Looking to the future, on-the-go sensors, whether attached to tractors or unmanned aerial vehicles, may also increase accuracy and decrease the cost of soil sampling. Authors: Jarrod O.

Soil Sampling for Optimizing Agricultural Production in Maryland (FS-1184)

Soil samples provide information about the soil fertility status of a field, which is used to generate nutrient and lime recommendations and develop a farm's nutrient management plan. This factsheet outlines proper soil sampling techniques (how, when, why) to optimize crop production, minimize environmental degradation, and maximize farm profitability.
