Managed to do a Johnson Su extract and spray it out over the weekend. Our extract method was to hose approximately 40kg through a screen so only the fine material was utilised <1mm at a guess. We then diluted this fine slurry material into about 900 litres of water and added in 20 litres of humate and 10 litres of seaweed (all I had left otherwise would have used more). Then sprayed out over the recently mulched and seeded 9.5ha of irrigation paddocks. Have then watered in with the equivalent of 6.5mm of rain.
As always it’s our first time trialling this so let’s see if it makes a difference.
