MICHIGAN AGRICULTURAL ENVIRONMENTAL ASSURANCE PROGRAM

Michigan Agriculture has a long history of protecting its natural resources. Michigan farmers recognize that the quality of the soil, water and air are directly affected by their production practices. In today's rapidly changing agricultural industry, integration and expansion seem to be the trend. Farmers and agricultural industry leaders recognize that, as operations expand, the potentials for pollution grow stronger.

In order to check the growing pollution potential, the agricultural industry along with government agencies formed a task force called the Michigan Agricultural Environmental Assurance Program (MAEAP). Created in April 1998, the MAEAP was developed as a result of livestock producers' desire to be pro-active concerning environmental regulation. A diverse group of industry leaders, producers and governmental agencies came together to form the MAEAP steering committee and set forth the MAEAP’s mission to develop and promote a recognized, voluntary, pro-active environmental assurance program. The mission targets the agricultural industry and ensures that producers are engaging in cost-effective pollution prevention practices that are in compliance with environmental regulations.

MAEAP is promoting the creation of nutrient management plans. Correct storage and utilization of animal waste, regardless of industry economics or policy debates, in conjunction with correct rates for the application of the nutrients to the soil is important. One of the issues that the MAEAP is working on is the USDA/EPA Joint Strategy on Animal Feeding Operations (AFO). This regulation will require livestock producers to create and implement a nutrient management plan.

The creation of a "farm stewardship plan" is another way that MAEAP plans to help farmers comply with regulations. This plan would assist agricultural producers in assessing the potential environmental risk on their farming operations. The MAEAP will give producers the tools and information needed to properly address current farm management practices and their environmental impact, as well as to stay in compliance with environmental regulations.

SILAGE BAG CAPACITY

How much material is in that silage bag? One way to estimate this value is to calculate the volume in the bag and multiply by its density. Although the bag is initially round, the shape after filling is more like half an ellipse. Therefore, the volume of the bag can be estimated as:

 

V = 0.79 H W L
where: V = Volume (ft3)
H = Height of bag above ground (ft)
W = Width of bag at widest (ft)
L = Length of silage (ft)

When full length bags are used, the length of silage is the bag length minus the unused portion needed to seal each end of the bag. Since the end of the bag often slopes, measure using a point that is about half-way (lengthwise) between where the bag touches the ground and where the slope starts at the top of the bag.

The dry matter density can vary from bag to bag and is based on machine type and adjustment as well as forage type. Typical densities range between 11-15 lb. DM per cubic foot.

Example: You have used a bag that had a 10 ft. diameter (specified by the manufacturer). After filling you estimate that the top of the bag is 3.5 ft. above ground (H=3.5) and the width of the bag at its widest point is 14 ft. (W=14). The length of the bag is measured at 80 ft. Therefore, the volume of the bag is 0.79(3.5)(14)(80) = 3,097 cubic feet.

If the density of the silage is assumed to be 13 lb DM per cubic foot, then the bag holds 3,097(13) = 40,261 lb. DM or about 20 tons DM.

If that same volume were packed to only 11 lb. DM per cubic foot, then the bag capacity would be 3,097(11) or about 17 tons DM.
