Bokashi vs Direct Burying

Michelle Wilson • April 17, 2025

Let’s be honest, any kind of composting is a big win for the planet. Whether you’re a hardcore composter, a casual scrap-burier, or a devoted bokashi bucket-lover, you’re doing something amazing: turning waste into soil magic.

If you’re new to composting or wondering why we believe bokashi beats simply digging a hole and tossing scraps in, keep reading.


"Why not just bury it?"

A good friend of mine swears by burying food scraps straight into her garden. For her, it’s simple, practical, and it feels like the most natural way to return organic matter to the earth. And she’s not wrong - it can work well, especially if you’ve got space, time, and soil that doesn’t need much adjusting.

Burying food scraps directly into the ground is certainly a no-fuss method. If you’re not planning to plant in that area any time soon or you’re not too concerned about fine-tuning your soil’s nutrient balance or pH, it might seem like the perfect solution.


But here’s the part that often gets overlooked:


When raw food scraps are buried, they need to go through aerobic decomposition (breaking down with oxygen). This process can take several months, depending on your soil’s temperature, moisture, and microbial activity.

During this time:

  • Up to 50% of key nutrients like nitrogen and phosphorus can be lost through leaching or gas emissions.
  • Pests may become a problem, especially if the scraps aren’t buried deeply. Rodents will catch the scent and dig them up.
  • Breakdown is slow, delaying when you can plant in that area.
  • Crucially, the nutrients aren’t readily available to your plants until full decomposition is complete.

So while traditional burying can work, it’s not the most efficient or nutrient smart way to return food waste to the soil - especially if your goal is to actively build a thriving, fertile, garden.

That’s where bokashi composting comes in…

 

Bokashi Composting

 

Bokashi composting takes your food waste to the next level helping you produce rich, living compost from your kitchen bench.


Unlike buried scraps that rot slowly and lose nutrients, bokashi uses a controlled anaerobic (no oxygen) fermentation process. Your food waste is sealed in an airtight container with a specific mix of beneficial microbes that ferment (rather than decay) the contents. This method transforms your waste into a pre-compost material. Since the food waste is fermented, there’s minimal nutrient loss and, best of all, no unpleasant smells, pests, or months spent waiting for it to break down. You're not just feeding your plants...you're restoring life to your soil.

Not All Food Waste Is Created Equal

 

One big advantage of bokashi composting is that it can handle all types of food waste, including meat, fish, dairy, cooked leftovers, citrus, and even small bones. These items are discourage from being buried directly into the soil, as they rot, smell, attract pests, and can disrupt the soil’s microbial balance. Bokashi’s fermentation process neutralises pathogens and odours, making even tricky food scraps safe to add back into your soil.


The benefits go beyond nutrients:

  • Bokashi improves soil structure — making soil lighter, airier, and easier to work.
  • Bokashi enhances water retention — especially helpful in sandy or dry soils.
  • Bokashi supports the soil food web — laying the foundation for long-term soil fertility.


So, while burying food scraps may feel like the natural solution, bokashi offers a faster, cleaner, and more nutrient-smart way to compost. And with a system that’s easy to use indoors and low in ongoing cost, its ideal for anyone wanting to garden more sustainably, whether you're based in the suburbs, on a lifestyle block, or in an urban apartment.



The Bottom Line

Bokashi composting is more than just a way to deal with food waste — it’s a smarter, faster, and more effective method of returning nutrients to your soil and supporting the ecosystem. By fermenting rather than rotting, you’re preserving valuable nutrients, avoiding pests and smells, and enriching your soil with beneficial microbes, all from the convenience of your kitchen.

Yes, there’s a small initial investment to get started, but ongoing costs are minimal at just 18 cents a day for the average family to create high-quality, microbe-rich compost you know and trust. And let’s not forget the simplicity:  just scrape, sprinkle, and seal.

That said, if you’re composting in any way, you’re part of the solution, and that deserves a high five! But if you’re looking for a method that’s fast, clean, and packed with soil-building benefits, bokashi is hard to beat.

Winterising your garden

By Mr Bokashi • June 1, 2022
Winter is an important time in the gardening calendar, as what you do during this time can dictate how your garden performs in the next growing season. One of the more important principals of regenerative gardening is to ‘keep the ground covered ‘ while the second principal is to 'keep roots in the ground.’ We are probably too late to get roots in the ground at this time, however, let's briefly cover this point. 'Keep roots in the ground' The most effective way to achieve this is by green or cover cropping. This is simply a matter of growing a green manure crop in any bare soil. These should have been sown out in April or May at the latest. The most common green crop is either lupins or mustard. I prefer to use rye corn because it produces dense and bulky roots, in addition to a good amount of green leaf. The many advantages of green manuring are: The ground is covered and protected against wind, rain, and sun. Weed growth is inhibited or limited. The green manure's plant roots loosen and aerate the soil. The plant roots foster both humus growth and the soil crumb structure Plant roots provide an important food source for soil bacteria and other soil-living organisms. Any green manure crops should be cut down before flowering and while the stalks are still soft. Often, we forget about our garden until after we have removed our final summer and autumn harvest. Consequently, we have overlooked the need to ‘keep roots in the ground’ and thus have to revert to the second best method.

Beat the heat in your garden

By Mr Bokashi • December 1, 2021
We are moving into summer, and I trust your garden is thriving. However, summer also means increasing temperatures and less rainfall which can lead to issues in the garden. The main issue is soil moisture loss which must be replaced by irrigation or watering. Water your garden either early in the morning or in the evening when temperatures are not so harsh. Watering in the heat of the day can cause leaf damage plus loss of water from evaporation. To reduce evaporation, you can also mulch around plants using good quality compost or pea straw. It’s best to ‘deep water’ once or twice a week rather than a little every day. Deep watering encourages plant roots to grow more deeply so they are better able to survive the ravages of summer heat. Increasing temperatures and regular watering creates a nice environment within the plant foliage, which provides ideal conditions for plant disease and insect infestations.

Preventing bitter lettuce

By Mr Bokashi • November 1, 2021
I am sure that every gardener has experienced the unpleasant taste of bitter lettuce leaves during their gardening journey. Lettuce is one of the easiest plants to grow, however it also tends to change from sweet and juicy to bitter quickly. So, how can we prevent this and grow fresh tasty lettuce for our summer salads? Interestingly, lettuces are cool climate plants although we tend to grow them during the warmer months of the years. Heat is the first culprit when it comes to bitterness as temperature change causes the lettuce to want to start to seed which is characterised by a plant with hard inner leaves. To avoid heat stress plant your lettuces in a semi-shaded spot in your garden. If you live in a hotter area of New Zealand, you may wish to consider planting your lettuces in the cooler months of the year such as spring or autumn and avoid mid-summer.

Feed the bees

By Mr Bokashi • October 1, 2021
Last month was Bee Aware Month 2021 so I thought it was the perfect opportunity to discuss how we can supply bees with an ongoing supply of pollen and nectar throughout the year by planting bee-friendly trees and plants in our gardens. Bees are incredible insects; however, they are under threat all over the world. Bees and other insects play a vital role by helping to pollinate our food. When bees forage for nectar and pollen they pollinate each flower that they visit which increases crop yield. Without bees many food crops that need pollination by insects could not be grown on a scale large enough to feed us. How then can you help these important insects to thrive? Simply plant something to create a bee friendly paradise in your garden. The easiest thing to grow are herbs. They do well in small pots with a bit of sun. Try something you can use in cooking such as basil, borage, rosemary, or thyme or any other herb of your choice. Just remember to let some flower as you want to attract bees to your herb garden. Anything that flowers will be perfect for all sorts of pollination. Try to have a couple of the plants flowering in your garden all year – rosemary is particularly good as it flowers for longer periods of the year when other herbs remain dormant. Add a little Earth Zing to the soil before planting your herbs to give them the best start.

Tips for terrific tomatoes

By Mr Bokashi • September 1, 2021
Tomatoes are one of the most popular vegetables to grow and nothing beats eating fresh juicy tomatoes straight from your own garden. Growing tomatoes takes a bit of effort but the rewards of biting into a delicious home-grown tomato that’s full of flavour and vitamins are well worth it. First steps To create the best quality tomatoes, you need good, healthy, fertile soil as the nutrients from the soil will fuel the growth of your tomato crop. Add good quality compost to your growing area to ensure your tomatoes have the best start to life. The compost created from your Zing Bokashi composting kit provides plenty of nutrients. As a guide, use one bucket for every two tomato plants. Four to six plants will yield a good harvest for you and your family.  I prepared a spot for my tomatoes a little while ago and have already planted my first plants. Now is a great time to get planting, whether you are planting outdoors or in a glasshouse. If you haven't a glasshouse, then site selection becomes important. Tomatoes love a warm and sunny spot and well sheltered from prevailing winds.

Prepare for spring and Christmas dinner!

By Mr Bokashi • August 1, 2021
The days are growing longer and we’re experiencing warmer afternoons which means that spring is just around the corner. The arrival of spring means a new and fresh start to a new growing season for all avid and budding gardeners. In this blog, we’ll look at a few simple jobs we can do to give us a flying start on our spring gardens and how to get started on planting your potatoes, so you have lovely new potatoes ready to harvest for Christmas Day. Prepare your soil By now you should have turned in any green manure crops back into the soil. However, if you haven’t done this you can do it over the next few weeks. Due to the recent wet weather, I have delayed this chore because of overly wet soil. If your soil is still very wet, holding off won’t cause any issues as generally your soil will also be cold. The soil needs to be warm and free draining to break down the organic matter in the green cover or manure crop. It’s also time to boost the nutrients in your soil. I recommend sprinkling some agricultural lime and or Earth Zing over your soil. Add these products just prior to digging over the soil. Even if you had bare soil over winter, it’s still fine to add these products. Don’t add any other fertilizers or plant foods at the same time and take care not to spread any lime where you will plant your potatoes as this can lead to a skin defect called scab.

What makes our Bokashi so good?

By Mr Bokashi • July 1, 2021
I need to wind the clock back to over 20 years ago when I developed our first Bokashi product (Compost Zing) to share the story of what makes our Bokashi so good. Starting in 1999, I spent over two years developing New Zealand’s first Bokashi product and was lucky enough to receive technical assistance from the late Dr Ravi Sangakkarra; a professor of agronomy in Switzerland and Sri Lanka. After Compost Zing went to market, Dr Sangakarra described Zing Bokashi’s Bokashi as the best Bokashi in the world. The word “Bokashi” doesn’t reveal much on its own as it’s a generic word meaning “fermented organic matter” and the ingredients contained in Bokashi products can range from low quality material through to the high-quality ingredients contained in our Zing Bokashi product. In my opinion, what makes Bokashi stand out is the use of locally produced high quality ingredients which are scientifically tested and proven to work. A good quality product needs to be technically sound and remain robust over time. That is why we spent plenty of time testing different materials and combinations when we were in the development phase of Compost Zing. Developing a product to meet these criteria took some time and it was a process of trial and error to develop our Bokashi product with many failures occurring along the way, however, those combinations which showed promise were lab and field tested until I was confident that we had a high-quality market-ready product.

Probiotic feed boosts poultry health

By Mr Bokashi • June 1, 2021
In 2012, a visitor to our stand at the Green Living Show in Auckland (now known as the Go Green Expo) prompted the development of Poultry Zing when they asked if we had a product suitable for boosting the health of their backyard chickens. This was around the time when there was a surge of interest from people wanting to have their own chooks within urban settings so they could produce healthy free-range eggs. After researching various options, I developed a suitable product to meet this request and Poultry Zing was born. The product was trialled by a selection of small poultry farm owners who reported that their birds produced more eggs which were larger in size, converted their feed better and appeared to be much more contented in general. Another benefit was that their faecal matter was more solid with a reduce odour. Poultry Zing as an organic probiotic feed supplement, but what how does this work to boost the health and wellbeing of your chooks? The term probiotic is used for products which stabilise the intestinal flora and these consist of one or a few well-defined strains of micro-organisms (World Health Organisation, WHO, 1994). Basically, by adding Poultry Zing to your chicken feed you boost the microbiological activity of the feed and improve the digestive process by enhancing the intestinal flora. It contains crushed wheat, bran, NuFeed and natural microorganisms (GRAS approved). Poultry Zing has grown in popularity as more people now have backyard chickens on their lifestyle blocks, rural and urban properties. We also supply Poultry Zing to commercial poultry operators who order in bulk – like this commercial client who orders 200kg at a time to add to their chicken feed.

Put your garden to bed

By Mr Bokashi • May 1, 2021
By now, you will have harvested your late summer and most of the autumn crops from your garden and will still have winter vegetables growing. After the last harvest of summer crops, my rule of thumb is to ensure that any bare ground that remains empty is “covered” during the cooler months ahead. This is my way of “putting the garden to bed” over the winter. Just like humans and animals enjoy resting when the temperature drops, so too do our gardens. “Putting the garden to bed” ensures that no bare soil remains and is thus protected from any heavy winter rain and ice while also preventing valuable soil nutrients from being washed away. To get the most out of this restful practice, sow a cover or green crop into any bare areas. There are two different options for boosting your veggie patch: 1. Cover or green crops help build carbon and roots in the soil, along with fostering and encouraging soil microbial activity. My preferred cover crop is rye corn, which is not only fast growing and hardy, but also has a thick root structure which provides lots of organic matter for your soil when its dug back in.

Starting your Bokashi Composting System

By Mr Bokashi • April 1, 2021
We have had some requests from customers to provide more information on getting started with your first Zing Bokashi Composting System. Like anything new, getting started with Bokashi can be exciting but also daunting. Luckily, our Zing Bokashi composting process is simple and easy to master. One of the greatest advantages of our composting system is that you can put all your kitchen food waste in your composting bucket including citrus, raw or cooked meat, fish, and chicken (including small bones). This means you can lessen your environmental footprint and avoid food waste going to landfill, while creating high-quality nutrient-rich compost for your garden. The closed-loop system means that your food waste is going back into the earth to fuel your next crop of home-grown vegetables or to enhance your flower beds.
