Farm based AD plant boosts performance and saves costs with silage additives

OMEX have added a range of silage additives to their products, designed to improve fermentation in the clamp, reduce aerobic spoilage and increase the ratio of acetic to lactic acid. This case study shows the proven results of using pHast and the resulting potential savings.

The standard ensiling process involves compressing silages in a clamp and preventing oxygen from penetrating the heap. The microbiology contained within the silage continues to respire using some of the available carbohydrates and producing mostly lactic acid for several weeks. As a result, the pH drops, which in turn inhibits the growth of unwanted microorganisms and therefore maintains the required crop characteristics. The key to saving as much organic matter as possible from spoiling, is the speed at which the pH decreases. The more favourable organisms present, the quicker it will decrease the pH and reduce spoilage losses.
