Soil Health Overview

We recently went to Marlborough and looked at the application of organic matter and compost in local vineyards and how it affects soil health. We brought along expert and soil consultant, Geoff Warmouth who gave us insights into the different soil types in the vineyards.


One of the biggest issues is the variation in soils. The same vineyard can have heavy clays at one end and stony soils at the other. Either way, what we discovered is that with the application of organic matter, you can greatly increase the holding capacity of moisture in the soil.


Going back to the basics:

4 things you need to create consistent vine growth:


Without these vital factors you may discover your vines aren’t getting the nutrients they need to grow to their full potential. This can lead to inconsistent vine growth and evidentially inconsistent wine.


“from a vineyards point of view, the more consistent the product the better. The bigger the root mass, the more energy it can store, the less stress with heat, the more consistency for the vineyard owner”.


How the  application of organic matter helps soil health

We found that soil without the application of organic matter was not getting the spread of moisture it needed to expand its root mass, whereas the soil with the application of organic matter was showing a greater spread or moisture that grew a deeper root structure for the plant. This relieves stress on the plant especially in those hotter months and allows it to use its energy in other areas.


With organic matter “the water drip is coming in and we’re covering a greater surface area and because we’ve got a greater surface area the moisture is now creating this teardrop underneath the root zone so the roots can spread out. If there was no holding capacity in the soil it would just be a little round circle, around about the size of a tennis ball on the surface and it would just run into a downpipe and disappear”.


Above and below the surface

A healthy plant has large-sized leaves which act as solar panels for the plant. These leaves work together with the roots mass to provide energy for the plant to grow. If there is not enough moisture for the root mass to expand then there is not enough root mass for the leaves to grow. They are a mirror image of each other so you can generally tell above the soil if you are having problems below.


Every vineyard may have different reasons for needing the aid of compost. Some want weed suppression, some want moisture retention, and others want to re-establish their organic content in the ground. Either way, if you choose to re-establish your organic content you will successfully solve all of the above.


“So when we want weed control or water suppression, people tend to put on too much and the trick to it is to do a little and often and get it working so that it’s actually utilised into the ground so by changing the soil structure, we change the weeds as well.”

Recommended depths

Typically you need a finishing layer of screened soil of 100mm when working with an uneven surface. 100mm of soil will allow to even out any hollows and give enough depth to create a flat surface

A general rule for compost is to allow for the depth of the current root structure of your plants with an additional 30-50% to mix in with the base. If you’re planting into holes or filling up a vege garden  you will need to accommodate for this prior to filling up

We recommend 100mm (10cm) deep for new bark gardens and planting into bare areas. For existing gardens with some cover, we recommend 75mm-100mm (7.5cm-10cm)

Note: Barked areas for playground impact protection need to meet NZS5828:2015 standards and is calculated on the fall areas and the height of the playground. Please contact us to discuss your barked playground areas

For paths and driveways which are often exposed to car and foot traffic, we recommend 100mm-125mm (10cm-12.5cm) on newly prepared areas due to settling of product.

This excludes preparation, compaction or drainage gravel underneath. For existing areas 75mm thickness is recommended for areas needing a small top-up.
