We have a range of catch crops available, suitable for any farm


The purpose of a catch crop is to increase annual dry matter production, to take up soil mineral and urine nitrogen and to reduce the risk of leaching or runoff. The key attributes of catch crops when following autumn or winter grazed crops are that they:

  • are cold tolerant
  • are winter active
  • have fibrous deep root systems capable of removing nitrogen at depth.

Catch crop benefits vary depending on weather conditions, particularly during establishment, with direct-drilling or light pre-drilling cultivation being recommended methods where possible to minimise nitrogen mineralisation.

Environmental benefits

Nitrate leaching is a naturally occurring process, but when excess N is lost from N fertiliser and N deposited in urine, not only is it a loss of valuable nutrient from the farm system, it can pollute both ground and surface water. This pollution is the focus of national and regional government strategies to improve water quality.
Nitrogen from fertiliser or urine can be problematic because when added to the soil, a large proportion is converted to nitrate (NO3-) which is especially susceptible to leaching. This conversion process is known as “nitrification”. Nitrification occurs relatively slowly in winter, offering a window of opportunity for catch crops to capture some N before it is lost through leaching. Catch crops sown after winter grazing can take up significant quantities of N and reduce N leaching losses by up to 50%. 

Establishing a catch crop after winter grazing can offer additional forage production perhectare, and in turn, higher farm productivity.

Mohaka has excellent early growth and cool season activity over the long rotation tetraploid Ohau. Mohaka is a broader leaved, well tillered hybrid suited to 2-4 year pastures.
Mohaka is ideal for undersowing into run-out pastures, with AR37 endophyte offering increased protection against insect attack and providing improved persistence compared to Italian ryegrass options.
Available with AR37 and AR1 endophyte


  • Ideal for undersowing programmes
  • Ideal for short term finishing pastures, runoff pastures and supplementary systems


Asset was bred from surviving winter-active, second year plants. Due to these attributes Asset is a perfect choice if a persistent Italian ryegrass is required. Asset has a high tiller density to encourage persistency, even under occasional heavy winter grazing.
Asset has excellent summer quality for its type, coupled with very high annual production. Asset was the first Italian ryegrass with AR37 endophyte.

  • Italian ryegrass available with AR37 novel endophyte and without endophyte (WE)
  • Excellent second year production potential
  • Low aftermath seed head for a true Italian


  • Ideal for undersowing programmes
  • Asset is a dense cultivar suited to winter grazing


Monty is a medium-maturity spring barley. It has consistently achieved high grain and silage yields over many trials. Silage quality is very good due to the high grain content. Trials indicate that Monty is capable of producing 8-14 tonnes DM/ha silage crops in Canterbury with irrigation and good management. Conventional barley has hard spiky awns that remain quite sharp in the stack. Monty is unique in this respect having reduced awns which minimise the damage conventional awns can do to soft, sensitive mouths, reducing animal stress and maintaining animal performance.

  • Hooded barley reducing the impact of awns during feeding
  • High yield whole crop barley
  • Excellent straw strength
  • Ideal catch crop option


  • Ideal for spring sown Whole Crop Cereal Silage
  • Ideal to be used as a catch crop to achieve high silage yields


Milton is a very high yielding oat with improved disease resistance and has the ability to hold quality until grazing/cutting. It can be planted in autumn to provide a single grazing in early to mid winter. Milton is also ideal for green chop cereal silage, either planted in autumn after a maize or summer crop or in early spring following a winter brassica crop.

Milton oats can successfully be used as a catch crop by planting after winter crops. Catch crops are used to grow in cooler temperatures to cover the fallow ground and take up the urinary nitrogen deposited by winter grazing to help reduce the risk of nitrate leaching.

  • Very high yields
  • Improved disease resistance
  • Rapid establishment
  • Can be used as a catch crop


  • Ideal catch crop option
  • Ideal for spring sown Green Chop Cereal Silage



Dual species catch-crop mix (Tabu+ and Hattrick oats) takes up N and increases ME, with the flexibility and reduced resowing costs from being a 12-18 month pasture.
Fast-growing species such as oats and Italian ryegrass quickly cover ground left bare after autumn or winter forage crops have been grazed. In doing so they utilise soil N and other nutrients deposited during grazing and prevent these from leaching. They also protect soil quality. Benefits are both environmental, and
systemic, as catch-crops provide valuable feed.


In summer-moist areas, sow Catchcrop+ ex autumn or winter crop for:

  • Efficient utilisation of soil N deposited during crop grazing, to reduce leaching
  • A high quality/yield spring silage crop with multi-graze and/or multi-cut fiexibility
  • AGRICOTE Clover can be oversown to Improve feed quality and fix N

In dryland areas, sow Catch-crop+ ex autumn or winter crop for:

  • Efficient utilisation of soil N deposited during crop grazing, to reduce leaching
  • Grass growth summer (moisture dependent), with fast response to autumn rain for high quality winter feed
