How do you break down clay soil quickly?
What is this? Certain plants – even commonly cultivated crops, are excellent for breaking up clay soil – potatoes, turnips, beetroot, and brassicas are all good options. Plant these in organic matter on top of the compacted soil and their roots can find their way down through into the compacted soil below.

Daikon Radish Seed
Fracking Daikon Radish is a deep rooted forage radish that will make an outstanding winter cover crop. The deep taproot of the large rooted plant can help break up the tough, compacted soil, improve water infiltration, suppresses weeds, eliminate pests and stores nitrogen.
Do radishes deplete the soil?
When the radish crops are terminated, the radish and roots leave large, open pores in the soil. This increases soil aeration and water infiltration.” Besides breaking up soil naturally, radishes can “scavenge” and clean up soil as well. They absorb extra nutrients.
Do radishes add nitrogen to the soil?
Radish is also known to benefit water quality. It does so by taking up nitrogen, in the form of nitrates, from the soil. This means less nitrogen in the soil that can run off to nearby streams and lakes.

But for all the hard work, clay soil has its benefits. Namely, it can harbor life-giving plant nutrients and retain moisture better than other soil types. With some soil amendments, you can turn your sticky clay into the humus-rich, fertile goodness that your plants will thank you for.
How can I improve clay soil cheaply?
Dig in plenty of bulky organic matter such as manure or, ideally, composted bark, as this can make a noticeable improvement to the working properties of clay. Apply organic mulches around trees, shrubs and other permanent plants as these will reduce summer cracking and help conserve moisture.
Is clay soil acidic or alkaline?
