Farm/Field and Commercial Horticulture Crops

Fields from above.

These tests are intended for farm fields or fields being used to grow commercial horticultural crops. The reports for soil samples submitted with the Farm/Field and Commercial Horticulture Soil Analysis Request Sheet will include crop-specific fertilizer recommendations. 

Here are two videos showing how to collect samples:
