Achieves rapid ground cover providing a quick, highly palatable grazing feed for sheep and cattle. Draws up subsoil nitrogen and nutrients, green manure biomass, aerates soil, breaks down compacted soil. Sowing depth 0.75 to 2.5cm

Key attributes

  • Breaks up compaction with a large taproot
  • Good forage production alongside soil benefits
  • Scavenges nutrients from depth
  • Fast growing cover crop
  • Suppresses weeds

About this variety

Buster is a tillage radish, grown to break up soil compaction biologically rather than mechanically.

Its large taproot drives down through compacted layers, and when the plant dies off the root decays and leaves a channel behind it. Those channels improve water infiltration and give the following crop's roots a path through a layer they could not otherwise penetrate, which is why the crop is described as a compaction buster. On many soils this is a cheaper and more durable answer than deep ripping.

The same deep root scavenges nutrients from below the root zone of shallower crops and brings them back to the surface as the residue breaks down, so nitrogen and other nutrients that would have leached are recovered.

Alongside the soil work it produces useful forage and grows fast enough to suppress weeds through canopy cover.

Buster suits compacted cropping ground, and is often sown in a multi-species cover crop blend where its rooting depth complements shallower rooted companions.

Planting & grazing notes

Sow Jan/Feb for maximum fodder/tuber development, also autumn/spring for quick feed; strategic grazing can delay maturity; drilling recommended for best establishment results. Buster Tillage Radish is also a short term fodder option (10-12 weeks) with first grazing in 5-6 weeks, & 2-3 grazings possible prior to maturity.

Disease & pest resistance

US resource guide notes nematode-suppressive properties (bacteriovore/microbial activity increase). They prevent soil erosion, improve soils physical and biological properties, suppress weeds, improve the availability of soil water, break pest cycles and store + supply nutrients.

FAQs

What can I sow to break up a compacted hardpan without deep ripping?

We recommend Buster Tillage Forage Radish. It was bred for a large tuber taproot that breaks up compacted layers. When the roots decay, they leave channels that improve aeration and water infiltration. It also draws nutrients up to the surface for the next crop. It suits soils with a pH (CaCl2) of 5.0–7.5 and a flexible spring, summer or autumn sowing window.

Need fast feed for sheep after summer rain, what can I get grazing in a month or so?

Buster Tillage Forage Radish is a quick option. First grazing is possible 5–6 weeks after sowing, and you can take 2–3 grazings before it matures at 10–12 weeks. It is highly palatable for cattle and sheep. Sow in January or February on good summer rain for the most feed and tuber growth, or sow in autumn or spring.

What cover crop gets a canopy up quickest to smother winter weeds?

Buster Tillage Forage Radish quickly grows a closed canopy, about a month ahead of oat and rye cover crops. That shades out weeds through winter and leaves fewer weeds in spring. It also produces high biomass and breaks down quickly, releasing nutrients for the following crop. It suits a flexible spring, summer or autumn sowing window.

Is there a cover crop that pulls up nitrogen that would otherwise leach out of sandy soil?

Yes, we recommend Buster Tillage Forage Radish. It produces more root mass than mustard or oilseed radish and two to four times the roots of cereals or grasses. That lets it mine nitrogen and other nutrients before they leach, then return them to the surface as it decomposes, which can reduce the need for extra nitrogen.

What should I sow with radish so stock get a balanced diet?

We recommend pairing Buster Tillage Forage Radish with a grass or cereal, such as our oats or an annual ryegrass, to balance the ration. Radish is very palatable, but brassicas can cause health issues if fed alone. Introduce stock gradually, avoid grazing in very wet conditions that undo the compaction benefit, and graze the tops so the plants regrow.

How do I graze a radish crop to get more than one feed out of it?

With Buster Tillage Forage Radish, start grazing at 5–6 weeks and graze off only the top part so the plants regrow. You can then take 2–3 grazings before maturity at 10–12 weeks. Strategic grazing can also delay maturity. Avoid grazing when the paddock is very wet, and introduce stock gradually as with any brassica.

Tillage radish vs Winfred brassica for grazing, what's the difference?

Buster Tillage Forage Radish is faster, with first grazing at 5–6 weeks and a large taproot that relieves compaction, but it is short-term at 10–12 weeks. Our Winfred Forage Brassica takes 10 to 12 weeks to first grazing but gives 2 to 4 grazings from early summer to late winter. Pick radish for soil repair and fast feed.

How much seed per hectare for a radish cover crop, and what rainfall does it need?

Our tech sheets recommend 8–10 kg/ha of Tillage Forage Radish, and the 2026 guide gives 5–8 kg/ha, so talk to us about the right rate for your sowing method and purpose. It suits soil pH (CaCl2) of 5.0–7.5 and is best on sandier soils. Drilling gives the best establishment.

How deep should I sow Tillage Forage Radish?

Sow Tillage Forage Radish 6–12mm deep in average soil conditions, going to about 20mm if the soil is dry. Drilling gives the best results, although it can also be broadcast or spread aerially. If you broadcast, use harrows or a light roller to improve seed-to-soil contact. The seed usually germinates in three to four days.

Tillage Forage Radish vs Black Mustard as a biofumigant-type cover crop, which should I pick?

If compaction is your main problem, we recommend Tillage Forage Radish. It produces more root mass than mustard crops or oilseed radish, and its large taproot breaks through hard layers. It also offers grazing within 5–6 weeks. Black Mustard is another brassica cover option, and both help break pest cycles in cropping rotations.
