In general, soft soils need more organic matter. Adding several inches of compost to the soil allows sandy soils to hold water and the necessary air pockets to clay soils so water can drain better.
How to Firm Up Soft Ground?
Soft ground can be a real annoyance for gardeners, landscapers, and anyone else working with soil. Whether the soil is too sandy or too compacted, it can be difficult to work with and can be a source of frustration. Fortunately, there are a few steps you can take to firm up soft ground and make it easier to work with.
The first step to firming up soft ground is to aerate the soil. This can be done with a garden fork or a special tool designed specifically for soil aeration. The goal is to loosen the soil and allow air and water to penetrate it more easily. This will help break up any compaction, allowing the soil to absorb more water and nutrients.
The next step is to add organic matter such as compost or aged manure. This will help improve the soil structure, increasing the amount of air and water it can absorb. It also adds nutrients to the soil, which will help promote healthy plant growth.
Once the soil has been aerated and amended with organic matter, you can add additional soil amendments as needed. This can include gypsum, lime, or other soil conditioners. These will help balance the pH of the soil, improve soil structure, and add additional nutrients.
