Straw bales are a very important component in enriching your land. To better know how many straw bales per acre you should use, here are some estimations that I have researched over time.

To cover one acre, farmers recommend using 100 bales. That’s because one bale will cover approximately 600-900 sq ft. Though this is dependent on the method you’re using to apply the straw bales, the size of the bales, and the thickness. The most common method of applying straw is using a straw blower (which will result in fewer straw bales being used as it’s more efficient). 

To estimate how many straw bales you’ll need per acre, there’s a lot more thought that goes into the process than just the cost. Here are some things you need to consider.

How Many Straw Bales Per Acre?

Ideally, you should use 100 straw bales per acre but there are factors that will determine whether you use more or less than the recommended 100 straw bales. These include:

Method of Application

There are two ways to apply straw; by hand or with a straw blower. The most efficient and less time-consuming method is to use a straw blower.

Applying straw by hand can be a time-consuming and labor-intensive task. Straw blowers offer a more efficient and cost-effective solution for applying straw to fields. They are capable of covering large areas quickly and evenly, resulting in better yields for farmers.

If you apply the straw by hand, there is a likelihood of using more straw than necessary which will result in a heaviness that hinders growth. Additionally, you may surpass the recommended 100 straw bales per acre.

Machines are generally more efficient than humans and that’s why I prefer to use a straw blower. In addition to saving you time, it will save you money by applying the straw evenly across the field.

A straw blower eliminates the risk of human error or uneven coverage that could occur when applying straw by hand. Furthermore, using a straw blower can reduce physical strain on workers since they don’t have to lift heavy bales of straw or bend over for extended periods of time.

The Land

When it comes to using straw bales for farming, the type of land plays a major role in determining how much you will need per acre. Different types of land require different amounts of straw bales to be effective. Straw bales are a great option for land that has little to no soil.

For example, sandy soils require more straw bales than clay soils as they are more prone to water loss and erosion. In this case, you would use more than the recommended 100 straw bales per acre to make up for the type of soil.

By knowing the type of land you have, you can estimate the number of straw bales per acre that you would require.


The weather is an important factor when it comes to the number of straw bales that you will use per acre. Depending on the season, the number of straw bales that you need could vary significantly. For example, during a dry summer, more straw bales would be needed to keep moisture in and slow down evaporation.

By using straw, you’ll only need to water your garden every other day rather than daily.

How Much Area Will One Straw Bale Cover?

One straw bale will cover approximately 600-900 square feet. That’s why you need 100 bales to cover one acre.

Another question you may be asking is why do you need straw bales anyway? Well, straw has a number of advantages that will greatly improve the outlook of your land. These include:

Increased Nutrients

Straw is one of the most important and underrated materials for increasing the nutrients in your land. It has been used for centuries as an effective way to improve soil fertility and increase crop yields.

Straw is an organic component that will decompose over time releasing nutrients into your land. This promotes the healthy growth of plants and actually makes your land/garden much better.

It’s Not Hay

Unfortunately, hay is not recommended to use as it can cause weeds on your land because it has grass seeds. That’s why straw is preferable.

Straw is acquired from wheat, barley, rice, oats, and rye and prevents weeds from cropping up on your land.

Prevents Pests From Damaging Your Crop

Straw is a natural material that can be used to prevent pests and diseases from affecting crops. It is an effective way to create a barrier between the soil and the plants, thus reducing the chances of pests and diseases damaging them.

Straw also helps to retain moisture in the soil, which can help to reduce disease-causing fungi. Additionally, it can also help to keep weeds away from crops, as it provides a physical barrier against them. This makes straw an ideal material for pest and disease prevention in agricultural settings.

How Many Bales Of Straw Do I Need?

This will largely depend on the amount of land that you have. You will need approximately 100 straw bales per acre so you can use this to calculate how many you will need for your land.

Using a straw blower will reduce the number of straw bales that you will need to cover your land. You should also use a straw blower if you have a large piece of land because it will save you a lot of time and energy.

If you have a smaller piece of land, you can apply the straw by hand but be careful to ensure that you don’t apply it too heavy or too light as this will hinder your plants’ growth.

The size of your lawn plays a huge factor in determining how many straw bales you will use. However, you will need approximately 70-100 straw bales per acre to cover your grass.

This figure will vary greatly depending on how big or small your lawn is but it should give you a good estimate. However, there are some things you need to consider when using straw bales on grass. These include:

Do NOT Use Too Much Straw

If you use too much straw on your grass, you will be hindering the grass seeds from growing and you won’t get the lush, green lawn that you want.

The soil needs enough air to breathe so that the grass seeds can germinate.

Do NOT Use Too Little Straw

Using too little straw is another problem that you should avoid because it will cause moisture to evaporate from the soil, especially during the dry season. Additionally, there is a possibility that the straw could decompose before the grass seed has the chance to germinate.

Remember that straw is an organic material that decomposes slowly over time. A little straw on grass will decompose faster than if you would have used the right amount.

To be on the safe side, always make sure that you’re using the right grass seed. Take the time to do your research and find out which grass seed is recommended for your specific area. Using straw will also ensure that weeds do not grow on your lawn alongside the grass. 

How Many Bales Of Barley Straw Per Acre?

The answer is still the same. Ideally, you would use 100 bales of barley straw for one acre. 

Barley straw has been used for centuries as a natural fertilizer and mulch, helping to improve soil fertility and provide essential nutrients to plants.

It can also help reduce weed growth by shading out light-loving weeds while providing essential organic matter to the soil. In addition, barley straw can be used to protect crops from frost damage in cold climates.


That concludes this article on how many straw bales per acre. I hope it gave you an estimate that will allow you to use your straw bales more efficiently.
