Description
Spreading pig manure late in the fall can have a variety of agronomic and environmental benefits To provide extension agents with information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer to that of pig manure spread in early fall, late fall, and in the spring.
Objective(s)
- Measure the impact of pig manure spreading date on crop yields and air, water, and soil quality
From 2014 to 2017
Project duration
Field crops
Activity areas
Soil health, Water protection, Air quality, Coexisting in an agricultural environment, Environmental regulations
Services
This project concluded that there is no major agronomic downside to applying slurry later in the fall, beyond currently allowed dates.
