Welcome to Agrovista Project Lamport

An innovative initiative from Agrovista and Bayer CropScience

About Agrovista Project Lamport

  • 14 different rotational systems set within a high indigenous black-grass population
  • Incorporates winter and spring cropping, autumn cover crops/spring wheat rotations, traditional fallows, hybrid rye for AD plants, winter wheat/OSR rotation and later drilling of winter wheat
  • All rotations will end up in winter wheat in final year
  • Success will be based both on final blackgrass control and economic return

The story so far...

NOW IN THE FOURTH YEAR OF THE LONG-TERM PROJECT SUPPORTED BY BAYER CROPSICENCETHE KEY OBJECTIVE FOR THE SITE CANNOT BE FORGOTTEN - CAN WE DEVELOP AN APPROACH TO RELIABLY DRILL SPRING CROPS ON HEAVY LAND?

 

If the last three seasons have proven anything, the answer to the above is yes we can.

We have successfully managed to drill spring crops into the heavy Northamptonshire land, and we have shown the vast potential of the correct cover crops to aid in the reduction of the blackgrass infestation while providing multiple soil, production, and environmental benefits.

It is well documented that ploughing, delayed drilling and most importantly spring cropping are key to controlling grass weeds.

 

The challenge going forward is to spring drill consistently.

We have achieved consistency by using the correct cover crop for the situation.

Low autumn biomass to allow blackgrass to germinate in the cover crop and with huge potential to condition and dry soils over winter is combined with our management best practice:

Correct desiccation timing for soil stabilisation

Check tractor tyre pressure to reduce unnecessary soil movement

Appropriate speed and direction of drilling to reduce soil movement

 

The long-term goal is to significantly improve the soil condition, reducing the impact of grass weeds and ultimately return the field to a wider rotation, including winter cropping. However, nothing is achievable if the profitability doesn’t stack up.

 

If we compare the Agrovista spring cropping system with common spring cropping practice, we can start to see the additional benefits the cover crop rotation brings to farm profitability.

As we have seen at the site, there is potential to destroy your cover crop earlier.

This is not detrimental to yield or grass weed control, however, it is not an option in year one of the system.

 

Barley as a spring option has the potential to be highly competitive with weeds and profitable.

Profitability is sharply declining for common spring cropping practice due to the ever-increasing blackgrass competition.

The AUK system is reducing blackgrass pressure, seed return to the soil and ultimately the blackgrass seed bank.

This can be illustrated by looking at the viable seed return to the soil after each year.

Common spring cropping practice has returned over six-fold the viable blackgrass seed to the soil compared to the AUK system and failed to achieve consistent blackgrass control in the growing season.

 

Key Principles of Successful Cover Crop use:

  • Choose the right cover crop for the job
  • Correct drill for minimal soil disturbance in the spring
  • Attention to detail

 

Crop management is key to perfecting this innovative approach to spring cropping and blackgrass management.
