Boost your manure with BioMest

BioMest is a 100% natural product that promotes manure decomposition and restores soil health. Its effective microorganisms ensure optimal nutrient and mineral uptake. This creates a balanced soil structure for your plants. It is intended to improve the efficiency of fertilisers and optimise crop growth.


It is an additive for your manure pit. It mixes easily into your manure. It improves the fermentation process. Ammonia is converted into organic nitrogen, which is then absorbed by plants. BioMest is highly concentrated, with 40 million beneficial bacteria per millilitre.


You can expect a manure improver to produce higher-quality manure. This makes the manure easier to process. For example, it can lead to less crust formation, less intense odours and better microorganism growth. It stimulates a natural process.
