Poisonous Plants on Rangelands: Deathcamas and Lupine

With prolonged drought conditions throughout many areas of South Dakota, there is an increase of invasive weeds and poisonous plants on rangelands. Identification of poisonous plants is crucial to ensure livestock production is not compromised.

Grassland Fertilization: Terminology and Economics

This article is the first in a series of six focused on helping producers understand the pros and cons of grassland fertilization. We begin by learning some of the basic terminology and information related to fertilization.

A native pasture community with noticable invasive plant issues.

Grassland Fertilization: Native Pasture Case Study - Hamlin County

Whether fertilization pays or not depends on the species present, the past management history and the type of grazing strategy. This study compares two very different plant communities that represent typical pastures and management schemes in this area.

Cattle grazing a high-diversity, native pasture.

Grassland Fertilization: Native Grass Planting Case Study - Codington County

Management goals of planted grasslands are an important driver in the consideration of whether fertilizer applications will be beneficial or harmful. Here, we will discuss various plant communities and the impact of fertilization on each.

Grassland Fertilization: Exotic Grass Planting Case Studies - McPherson and Jerauld Counties

Our previous installment of this series discussed the effects of fertilization on native grassland plantings. This last installment addresses the options for fertilization on low-diversity exotic grassland plantings.

Cover Crop Adoption: Farmers’ perceived benefits & barriers

Cover crops are generally defined as crops planted between cash crops to cover and protect the soil. Some demonstrated benefits of cover crops include: reduced soil erosion, increased soil organic matter, increased biological diversity, increased nitrogen supply, and weed control. Depending on the farmers’ objectives, different species of cover crops can be planted. For example, if a farmer’s main objective is to increase nitrogen supply, then legume cover crops best suited to the farm area should be selected.

Poisonous Plants on Rangelands: Hemlock, Halogeton and Buffalo Bur

Several species of poisonous plants are invasive and can easily establish dense stands when there is a disturbance on rangelands. Hemlocks, halogeton and buffalo bur can all be found throughout South Dakota and are toxic to livestock.

Poisonous Plants on Rangelands: Larkspur and Poisonvetch

Larkspurs are the second leading cause for all livestock deaths from toxic plant poisoning. Poisonvetches are considered accumulator plants that uptake excessive levels of selenium and cause toxicity problems in cattle.
