What is the Value of Effluent for Dairy Farmers?

We often hear from farmers how much of a difference effluent has made to their pasture. It’s not just about the nutrients either. Managed well, effluent boosts soil health, improves crop resilience, and can even help during dry spells. Curious what it could do for your farm? Keep reading..

There is a lot of focus on the nutrient value of effluent. This is easily measured, so is the value most frequently discussed. Although it varies from farm to farm, depending on the feed system, rainfall, herd size and management practices… a typical average is around 5kg Nitrogen, 1kg Phosphorous and 5Kg of Potassium. There is also some sulphur and other trace elements.

The real value of effluent

The real value of effluent compared to synthetic fertiliser is the effect on soil biology. Boosting soil microbes improves the cation exchange capacity of the soil, making nutrients available for crop needs over a longer period.

Synthetic fertiliser on the other hand is harmful to the soil biology and reduces the soils ability to retain nutrients.

Nitrogen fixing bacteria such as those associated with clover roots convert atmospheric nitrogen into a plant-available form. Considering the atmosphere is 78% nitrogen it makes sense to use it. Feed the soil and let the soil feed your crops.

The irrigation value of effluent should not be overlooked, particularly if you don’t have any other form of irrigation. Effluent applied to help a crop get established or save a few paddocks in a dry spell is worth thousands.

To maximise the irrigation value from effluent we recommend plenty of storage.

Getting the most out of your effluent system starts long before spreading. Correct stirrer placement plays a major role in how well solids are broken down, nutrients are suspended, and the slurry remains consistent. If a stirrer is poorly positioned, even the best equipment can struggle to deliver reliable results.
