S.D. Producers’ Willingness To Adopt Patch Burn Grazing vs. Winter Patch Grazing

Patch-burn grazing and winter patch grazing are heterogenous rangeland management practices that aim to increase the variety of grass composition to benefit wildlife and maintain livestock production. To learn about producers’ desire to adopt these practices, we conducted an online survey between November 2019 and January 2020.

Prussic Acid Poisoning

As the first frost date approaches, producers often have concerns about the risk of prussic acid poisoning in livestock. Certain forage plants, especially sorghums and related species are associated with an increased risk of death loss because of prussic acid poisoning.

Former cropland replanted with a variety of grasses and broadleaf plants.

Replanting Cropland Back to Grassland

Planting cropland back to grassland takes some planning regarding previous herbicide use, soil fertility and seed bed preparation. The first step is to identify what resources are currently available to help you reach your objectives and what problems may need to be addressed.

Left: Soil from long-term no-till field, exhibiting good soil aggregation through clumping and smaller pieces of soil. Right: Soil from conventionally managed field that included tillage and crop residue removal. Notice the soil is lighter brown, indicating lower organic matter, and the pieces of soil are in larger chunks with no visible indication of clumping or structure.

Organic Agronomy Starting to Impact

For decades scientists have known that a handful of soil contained more micro-biological organisms than the number of humans on earth. Science is just beginning to discover these organisms and learn about their functions and contribution to their soil ecosystem.

Swath/Bale Grazing

Swath grazing and bale grazing are harvest systems that mesh haying and grazing techniques. Generally, the objective is to reduce labor and equipment expenses by allowing livestock to consume the hay crop in the field.

Fall Frost and September Climate Outlook for 2019

This year’s struggles with weather and climate are continuing this fall. Late planting of corn and soybeans in the spring have now combined with near average or cooler than average summertime temperatures. This combination has led to slow crop growth and the need for an extended frost-free season to ensure these crops reach maturity.

How’s Life in the Soil? Ask (Count) the Earthworms.

Earthworms are ‘very special’ creatures on earth, and their contribution in soil nutrient cycling and fertility management has been acknowledged from the beginning of agriculture. So, the question needs to be asked, how can we help improve earthworm populations?
