Organic Digester

Decomposition product for faster plant breakdown and nutrient recycling.

>> Looking for the non-organic version?

Releasing and recycling the nutrients in organic matter back into the soil is done via the process of decomposition.

Enhancing decomposition by activating naturally occurring microbes speeds up this breakdown, delivering a number of benefits like faster crop rotation, soil enhancement and orchard hygiene.

Biostart Organic Digester is a decomposition product that stimulates decomposition microbes for faster breakdown and composting of organic matter.

Organic Digester enhances the decomposition of prunings, leaf litter, cover crops, old roots and post-harvest crop stubble – recycling nutrients faster and more completely and building soil ready for the following seasons’ crops.

Use Biostart Organic Digester to:

  • Return nutrients and organic matter to the soil for improved plant nutrition

  • Increase the soil’s cation exchange capacity (CEC)

  • Increase the soil’s water holding capacity

  • Improve soil aeration and structure

  • Increase new root growth by breaking down old roots in mature orchards and vineyards

  • Reduce plant disease by decomposing the organic material it feeds on over winter

  • Prepare annual crop seedbeds for the following season

  • Breakdown cover crops quickly before planting the following crop

  • Activate compost to enhance soil faster.

Organic Digester is made from fermentation extracts of the beneficial soil microbe Pseudomonas putida, which work by activating the saprophytic fungi in the soil involved in decomposition. 

Organic Digester is certified organic.

Directions for use:

  • Invert container and shake well before use
  • Apply Organic Digester directly on to crop trash or prunings
  • Needs soil moisture/rain and active soil biology
  • Organic Digester can be tank mixed with herbicides, fertigation nutrients and suspension fertiliser
  • Organic Digester can be applied through fertigation systems and through overhead irrigation systems fitted with an appropriate system.
  • In low organic matter soils, low fertility soils or after drought add technical grade ammonium sulphate at 30 kg/ha
  • For best results avoid applying Organic Digester in the heat of the day.

Crop specific information

If prunings are to be mulched then apply a total of 4 L/ha: in early autumn apply 2 L/ha on to prunings, and apply a further 2 L/ha after the prunings have been mulched.
Premium Programme or for heavy disease overwintering, cut-out diseased vines, compacted or water-logged soil: Apply 4 L/ha in a minimum of 200 L applied over leaf litter & prunings to the soil over the whole vineyard floor. If prunings are to be mulched then apply a total of 6 L/ha: in early autumn apply 4 L/ha on to prunings, and apply a further 2 L/ha after the prunings have been mulched.
Pipfruit, Berries, Stonefruit, Citrus, and Avocadoes Autumn/Post-harvest; Post-pruning and/or leaf fall 4 L/ha in a minimum of 200 L of water applied over leaf litter and prunings to the soil.
For heavy disease over-wintering, cut-out diseased orchards, compacted or water-logged soil: 6 L/ha in a minimum of 200 L of water.
Kiwifruit Autumn/Post-harvest; Post-pruning and/or leaf fall 6 L/ha in a minimum of 1000 L of water applied over leaf litter and prunings to the soil. For heavy disease over-wintering, cut-out diseased orchards, compacted or water-logged soil: 8 L/ha in a minimum of 1000 L of water.
Vegetables including sweetcorn Post harvest 4 L/ha in a minimum of 200 L of water applied over crop trash to the soil.
For crops with heavy disease over-wintering e.g. asparagus apply 6 L/ha in a minimum of 200 L of water.
Pasture and Turf Autumn 2 L/ha in a minimum of 200 L of water.
Maize and Cereal Silage Post harvest Apply 2 L/ha in a minimum 200 L of water to the soil during or after stubble incorporation.
Maize for grain Post harvest Apply 4 L/ha in a minimum of 200 L of water to soil during or after stubble incorporation.

To reduce application cost: Co-apply with other commonly used organic fertilisers. Digester can be applied via ground sprays, overhead sprinklers or fertigation systems. For high crop residue levels, an organic nitrogen source may be recommended to further assist decomposition. Call BioStart for further information.

Mixing instructions: Partially fill the spray tank with clean water and start agitation. Add the required amount of Organic Digester to the tank. Complete filling the tank with the required volume.

Application: The decomposition process takes time in colder temperatures. For best results in spring, apply in autumn or early winter. Apply early morning, early evening or in overcast conditions to moist soils and wash or rain in. For best results finely cut woody material. Calibrate sprayer before use. The Organic Digester application rates above can be applied in 200-1,000 L/ha of water.

Nil withholding period.
