Silage and Wholecrop Analysis


At our state-of-the-art lab in Ballaghaderreen, our dedicated team carries out scientific testing to give our farmers the accurate information available.

At Nutrias, we provide grass and maize silage and wholecrop testing to provide our farmers with a simple and accurate report guideline on forage quality and supplementation strategy for your animals.

The scientific analysis is carried out by our full-time team in Ballaghaderreen where a range of tests are conducted to analyse for quality of preservation, protein content and energy value.

Your forage report will be provided in a simple and clear matter but will include in-depth results, such as fermentation characteristics (including pH, ammonia and lactic acid), chemical composition (such as crude protein, ash and dry matter) and nutritional feed value (including metabolisable energy, dry matter and digestibility).

Some of the benefits of silage testing include allowing you to budget and prioritise forage, improving animal performance and feed efficiency and providing sustainable usage of home-grown forages.

At Nutrias, we offer a range of soil analysis options which provide information on the health of your soil and the nutrients it contains.

This analysis will allow us to provide you with a clear, individual plan on how you should treat your soil after the test. This efficient way of treating your soil will result in the cost effective use of lime, fertlisers and trace elements.

The best time to test your silage is at least 6 weeks after silage is harvested to ensure that the fermentation has been completed. And it should always be done before you choose a supplementation type or start creating your supplementation strategy.

How you take the sample is important. They should be taken from 15-20cm behind the face of the pit or bale and then placed in a bag. Ensure there is no air in the bag and seal it carefully. Ensure you do not include mouldy or contaminated silage in the sample.

Pre-ensilability testing


Reduce the risk of poor quality preservation and know the right time for ensiling with our pre-ensilability testing.

Our pre-ensilability testing will enable you to manage the nitrogen content of your grass to reduce the risk of poor quality preservation and will give you scientific advice on crop suitability for ensiling.

When ensiling silage the aim is to get the bacteria in the silage to convert the sugars available as quickly as possible to lactic acid to drop the pH of the silage to around 4, this is where the silage is stable. The higher the sugar content the more food for the bacteria the quicker the pH drops. The target sugar content to ensure good fermentation is 3% or higher.

High Nitrate levels in grass are bad as they increase the buffering capacity making it more difficult to get the pH level down. As grass grows it uses 2 units of Nitrogen per day, so if you applied 100 units per acre, it will take on average 50 days for this fertiliser to be used up.

If your nitrate test reading is high, the most likely cause is that not enough time has elapsed from the spreading date.

Interpreting your silage report


Grass Silage Analysis Explanation

Assessing a silage report:

There are 3 main components on the report:

  1. Fermentation quality e.g. pH, Volatile Fatty Acids, Lactic Acid, Ammonia, WSC
  2. Chemical composition: e.g. Crude protein, Ash, NDF, ADF
  3. Nutritive value: e.g. DMD, ME
