Soybeans on rolling Pembroke soils

Pembroke soils, with their deep loess surface and fertile subsoil, are among the stronger row-crop soils in western Kentucky. Their good water-holding capacity, friable surface texture, and neutral reaction make them well suited to soybeans. In field trials and on working farms, yields on Pembroke silt loams are consistently solid—commonly in the 50 to 60 bushels per acre range, with higher yields possible under favorable weather and management.

 

Farmers who maintain soil fertility, manage pH with lime, and use no-till or reduced-till practices to conserve moisture often see Pembroke fields perform at or above county averages. In good years, with timely rains and optimal seed fill conditions, soybeans on Pembroke soils can surpass 65 bushels per acre, matching the best upland soils of the region. Even in more average years, the resilience of these deep, well-drained silt loams helps maintain dependable yields, making Pembroke soils a cornerstone of soybean production in western Kentucky.
