Olsson’s Biochar Block 18kg

Olsson’s Biochar in the diets of livestock appears to increase growth rates, pasture production and permeability of soil. Biochar has a high surface area.

It binds toxins and improves rumen habitat. Biochar also helps promote dung beetle activity.

Available in store.

What is Biochar?

Any organic matter (e.g. wood, manure or plant matter) that is heated in a closed container with little or no available air, to 400 – 500 degrees Celsius.

Biochar is found in soils around the world as a result of vegetation fires and historic soil management practices. Intensive study of biochar-rich dark earths in the Amazon (terra preta), has led to a wider appreciation of biochar’s unique properties as a soil enhancer.

The Benefits of Biochar on Cattle Production

Generally improved health and appearance
• Improved vitality
• Improved udder health
• Decreased cell counts in the milk (interrupting the administration of biochar leads to higher cell counts and a drop in performance)
• Minimisation of hoof problems
• Stabilisation of postpartum health
• Reduced diarrhoea within 1-2 days, faeces subsequently generally more solid
• Decline in the mortality rate
• Increase in milk protein and/or fat
• Combining biochar and sauerkraut brine has proved worthwhile
• Marked improvement of slurry viscosity, with less stirring needed and less scum on the surface
• Slurry not smelling as bad as it used to
• Preliminary tests on the slurry show that adding biochar via the gastrointestinal tract or via direct application
• Increased ammonium nitrogen
• Reduced nitrate and nitrite

The Benefits of Biochar on Soil Health

Increased nutrient retention
• Reduced leaching
• Increased cation exchange capacity
• Improved soil structure
• Improved water holding capacity
• Decreased soil acidity
• Increased microbe count

The Benefits of Biochar on Dung Beetles

Biochar absorbs nutrients from rumen and dung
• Dung beetles carry nutrient rich biochar into the ground
• Biochar stays in soil and doesn’t get broken down
• Beetles bury dung, minimising buffalo fly cycle & parasitic worms
