Fertilization and the Influence of Soil pH

May 12, 2023

Rejuvenation of a forage stand, whether hay or pasture, involves using one or a combination of methods to increase productivity with a shift towards higher yielding forage species that provide improved nutritional value for livestock.

If an assessment of the current forage stand shows that there is not enough of a desired plant species, then fertilization can be an effective tool to reinvigorate and increase forage yields. Starting with a soil test, improving nutrient deficiencies can increase forage production.

Before making the investment in fertilizer, soil pH should be accounted for in conjunction with fertilizer plans—in the event of low soil pH, nutrients may be present in the soil but unavailable for uptake by plant species. When soils are very acidic (pH less than 5.8), soil bacteria and nitrogen-fixing bacteria in legume stands are negatively affected and soil biological activity is reduced. The opposite of this is also true, raising the pH too high can reduce the solubility of aluminum and manganese, which can be potentially toxic to plants at high levels.

Video: Five Confirmed New World Screwworm Cases Raise Alarm for Livestock and Pet Owners

Pat Hoffmann, Swine Technical Consultant at Elanco Animal Health tells us about the impact of New World Screwworm. The emergence of New World screwworm in the U.S. creates a threat for veterinarians, livestock producers and pet owners that has not been seen north of the Florida Keys since the fly was eradicated from the United States more than 50 years ago. New World screwworm (Cochliomyia hominivorax) larvae feed on living tissue and can affect a wide range of warm-blooded animals, including livestock, companion animals, wildlife, and even humans.
“New World screwworm could have a devastating impact on animal health, welfare, and producer livelihoods,” said Jeff Simmons, President and CEO, Elanco Animal Health. “We want to thank the FDA, EPA and USDA, for all their work to prepare for this threat. We’re committed to supporting our customers during this challenging time by delivering innovation, scientific expertise, and available resources to help treat New World screwworm and support the health and well-being of animals.”
Elanco is working alongside the U.S. animal health industry to help them fight against this parasite, offering a portfolio of options for pets and livestock that can help treat New World screwworm larvae infestations.
