CASE STUDY – CROP YIELD ENHANCEMENT
Successful Manure Management Program at PFLEEGOR FARM, Lewisburg, Pa 2002 Hog Manure
Gary Pfleegor is a CVFF Contract Grower operating a compact 15-acre, two barn facilities on a tract of land that includes his personal home.
This Swine Farm is relatively new and Gary has incorporated some of the latest technologies to optimize his Grow-Out Operation. His barns are kept in excellent condition. They are cleaned and the surfaces sanitized following each “grow cycle” to reduce potential problems within each production colony.
Gary used Microbe Lift IND to improve the condition of the manure for easier transfer at the time of pumping, as the pits had developed a problem with sludge and bottom solids, and the pits had to be agitated, which made it harder to spray on the fields.
Gary worked with his Contract Pumper to evaluate Microbe Lift IND performance in:
- improving manure removal and reduction in bottom solids,
- odour and fly reduction,
Gary was convinced that the heavy fly populations were a contributing factor in the health of his herd. In addition, his home was located extremely close to his barns, so any improvement in odour and fly reduction would improve conditions for his operation and as well as his own living conditions.
One barn was treated in 2000, with six gallons of Microbe Lift IND applied to the 1.32 million litre storage pit after pumping out the waste pit. This was followed by one gallon each week for the next four weeks, and then maintenance treatment of one gallon each month until the next waste removal six months later.
During the first year’s trial Gary reported a reduction in odour and fly populations in the treated barn, with these results evident almost immediately. However, the results were confirmed at the time of waste removal when the pit’s bottom and sides were found to be extremely clean and the two feet of prior waste solids, which had usually remained in the pit after pumping, was completely gone. Following this, Gary treated both barns with Microbe Lift IND in 2002. He reports that his herd health is in significantly better health, its mortality rate has been reduced for 5% to 2%, and there is much less odour in the barns and surrounding area, and far few flies.
With regards to the impact of fly reduction, Gary remains convinced that fly reduction and their control is most important to the facilities health control issues, as flies transmit potential deceases for the waste pit to the hogs. When flies seem to return, Gary simply applies one additional gallon to each side of the barn’s pits and flies are eliminated within 12 hours. Gary said Microbe Lift IND just makes going to the barn a lot more pleasant, and he has not seen a solid manure build-up since using Microbe Lift IND.
In addition Gary and his family have benefited greatly, as they can now leave their windows open on any day or evening, even during the hottest of weather. He said could not do this before to using Microbe Lift IND due to the high level of odour and the large fly populations.
Now for the big surprise the treated manure waste was then land-farmed as fertilizer in surrounding corn fields. The results were incredible. First, there was no odour during pumping, transportation and spreading (spraying) the fields. Obviously this made everyone quite happy, as there had been many complaints from the community in the past. But what made the Farmers even happier was the impact on Crop Yields, at harvest they had a 50% increase increasing from 120 to 180 bushels of corn per acre! Therefore, what was going to be a cost of business…treating the manure pits was now a profit centre that more than paid for the treatment with increased Crop Yield.
