How To Remove Rocks From Soil Using Machine and Manual Process?

Garden enthusiasts, whether on a professional or personal level, can relate to the problem of working with rocky soil. For your garden or lawn, rocks can create a hazardous situation. Rocks can damage equipment used for tilling or any other purpose.

Deep rooted plants cannot grow properly in rocky soil. So it is very important to have proper knowledge on how to remove rocks from soil. The following methods will help you to understand how you can do this kind of work in the best and easiest way.

Why Are Rocks In Soil?

Rocks are naturally occurring. Even in extremely cold places you will find rocks.

This continuing appearance of rocks will always surprise you. In the East-Coast of the USA, these naturally generated rocks are known as “New England potatoes!”

As wet soil becomes solid, it expands upward. When the ground thaws rocks will automatically be pushed upward. After repeating this process again and again, the rocks appear in the soil.

These rocks can cause serious damage not only to your plants but also your garden equipment like tillers and cultivators.

While tilling in the garden, the rocks can be flung out and hurt you. Sometimes the over-crowding of rocks can kill plants due to hampering their natural growth. So it is very important to be aware of the rocks in the soil.

Types of Rocks / Gravel Found in Soil

​There are four types of rocks can be seen in the soil and they are described below:

Large Rocks

In the mountain and foothill areas, these big blocks of rocks are noticeable. In mountain valleys, the soil ismore fertile and easier to work. If your land is in these kinds of places, be aware of the rocks and remove them before attempting any further work.

Medium-Sized Rocks

In terms of bigger rocks, the medium sized rocks are harder to find, since they tend to be 8-12 inch deep. Try to clear them out with the help of a shovel and tiller. After turning the soil surface, use your hands to remove the medium sized stones and add some nutrients before planting.

Smaller Rocks

To saturate the ground evenly the garden or lawn needs to water in an appropriate manner, but the smaller rocks hinder the process to do this correctly. So they need to be removed with rakes or by hands, even though it will take time.

Pebbles

The pebbles and tiny rocks usually don’t make any difference to your gardening, but if you don’t want them then you can clear them out. You can use a sifter to remove the small pebbles; rakes are also useful in this matter.

Why Should Rocks Be Removed From Soil?

In one sense, the rocks don’t directly affect the plants, but if there are lots of them, then it might be a serious concern. In rocky soil, nothing can grow well as plants cannot spread their roots through the rocks.

Thus the rocks indirectly affect the plants or grass in your lawn or garden. When plants cannot reach underground sources of water, they look skinny and unhealthy.  

At the same time, they are deprived of natural minerals and vitamins from the soil, and thus the growth of the plants becomes slow and limited.

A few crops like potatoes and beetroots are impossible to grow in rocky soil as they need plenty of soil for their growth. These are the major reasons your soil must be free of rocks to have a healthy and fast growing garden or lawn.

List of Rock Removal Tools

There are several garden tools to remove the rocks from your yard or garden bed, among them, these are the most commonly used equipment:

• Rototiller: This powerful tool is very effective at breaking up dirt, so that the soil is loose and large rocks can be removed easily.
• Cultivator: This machine can be used to uncover both large and medium rocks. You can even rent them for a short period.
• Garden rake: A rake is helpful for gathering the gravel or small stones.
• Gardening gloves: Another important thing you must have when removing rocks is a pair of garden gloves

Depending on the soil consistency, you may also need a pointed shovel, wheelbarrow and soil sifter.

How To Remove Rocks From Soil Manually

To maintain the health of your garden you should remove rocks with utmost attention. This is obviously a tiring and time consuming job to do but once you are finished the result will be worth the effort.

• If you find a big rock, instead of using a shovel, use your hand to work it out of the soil.
• For small rocks, scoop the soil and pour on top of the screen.
• Tip one edge to allow the rocks slide down and the soil to sift through the net.
• Now use a spade to remove the debris and rocks from the bottom.
• Take a box scraper to free the topsoil from rocks.
• Unless you remove all the rocks by rototiller from the soil, keep doing this process.

If you need to use a machine to remove soil from a huge area, a tractor can be a cost efficient method.

On the other hand, if you do this manually, it may require hard labor and take time by using tools like a plow, spade and shovel. If you use a machine, you will still you need to do some manual work.
