Water
Cyanobacteria Poisoning (Blue-green Algae)
Drinking water from stagnant ponds and dugouts during hot, dry weather can cause sudden death in animals. This water can contain certain species of cyanobacteria (glue-green algae) are toxic. Cyanobacteria produce neuro and liver toxins that are poisonous to nearly all livestock, wildlife and humans.
Livestock Water Requirements
Water is an important, but often overlooked, nutrient. Livestock water requirements are affected by many factors including, size, productivity, diet and environmental conditions. Limited access or reduced water consumption can result in dehydration, which can be fatal to livestock.
Environmental Implications of Excess Fertilizer and Manure on Water Quality
When nutrients and other pollutants associated with animal manures and commercial fertilizers are not managed properly, they can affect plant and animal life (including humans) negatively. Some of these impacts include algae blooms causing the depletion of oxygen in surface waters, pathogens and nitrates in drinking water, and the emission of odors and gases into the air.
Nitrogen Behavior in the Environment
Manure and commercial fertilizers contain nutrients essential for plant growth. Nitrogen, phosphorus and potassium are the most critical of these nutrients. This publication outlines some basic information about nitrogen and its interaction in the environment.
Phosphorus Behavior in the Environment
Phosphorus (P) is a naturally occurring element that exists in minerals, soil, living organisms and water. Plant growth and development require phosphorus, like nitrogen, in large amounts. Phosphorus is essential for early root development and hastens plant maturity.
