Issues Relating To Different Soil Types    

Answers to frequently asked questions about issues relating to different soil types.

How Do Soil Types Affect Application?    

Soil properties vary considerably and there are over 140 soils types in the Tasman region alone. The texture and structure of soil can influence how effluent moves through the soil profile. This is also influenced by slope, artificial drainage and compaction resulting from pugging or mechanical pressures.

Soils with greater than seven degrees slope (that is when the ball starts to roll), impeded drainage or artificial drainage are generally risky soils for effluent application because the volume and speed of application can create problems with surface run off or bypass flow.

Well drained land doesn’t have the same issue with volume and rate as the liquid can move evenly through the soil profile. However it can become risky if the nutrient content of effluent is high and applied at a time of low plant growth. This is because the nutrients will leach through the soil faster than the plant can use it.

What Are The Storage Options For Peat Soils?    

Peat soils provide a number of construction challenges due to water levels and potential slumping risks. The assessment of options needs to be site specific and it is recommended that consultation is made with a suitably qualified engineer or geotechnical expert when designing and constructing farm infrastructure.
