Maize is more water efficient and stores more carbon than many other crops. Maize is also an excellent target crop for the efficient use of organic manures Such positives must be balanced with the soil structure, nutrient overload and biodiversity challenges associated with the crop. The MGA environment publications, being free to all, attempt to inform growers of the positives and potential negatives of growing maize and other wholecrop forages.

Clean Air Strategy

Wednesday, December 12, 2018

Observant members amongst you will have noticed that there are changes in how we manage ammonia emissions being proposed in the Clean Air Strategy 2018 recently published by the government. 

 While the strategy has yet to be finalised, several key principles have been established and should be considered by growers when planning their organic manure, including digestate, and manufactured nitrogen applications in future. 

See John's article in Environment section of the website.


European maize meeting report

Thursday, November 1, 2018

In early September John Morgan and Simon Draper attended the European Maize Meeting (EMM), this year held in Belgium, on behalf of the MGA.  The meeting, hosted jointly by the Belgian maize  organisations, Uclouvain and CIPF, was held in Gembloux, approximately 50 km south east of Brussels and as in the past consisted of three elements.

 A classroom-based session when the Status of the Maize Crop in different countries was outlined by our hosts.

 This year’s chosen subject was Undersowing and the Impact of Undersowing on Nutrient and Soil retention.

Moving silage

Thursday, November 1, 2018


In his latest Technical Note for MGA members, Mike Wilkinson outlines procedures for moving silage from one place to another prior to use.  Mike can be contacted via the MGA office.

 Silage is in short supply and may have to be moved from one site to another before use. The material may have been stored in a bunker or temporary unwalled heap (field clamp or pile) some distance from place of use because existing silo capacity was inadequate, or because insufficient silage was made on site to meet demand.

Costs of production

Monday, August 20, 2018

The latest in the Costs of Forage Production series is based on average yields and quality.  Costs of production are assume contractors undertaking establishment and annual management tasks with crop nutrients being supplied by straight inorganic (bagged) fertiliser.  No feed out costs or waste are included. 


Westerwolds offer a real opportunity

Monday, August 20, 2018

The hot, dry conditions have hit/ obliterated most second and third cut silages, as well as impacting on many maize crops, to the point that many growers are currently short of grazed grass as well as being down on forage stocks for the winter.  The likely early harvest of maize this autumn and recent rain does offer some opportunities to fill the forage gaps, as do extending grazing in the autumn and hopefully next spring.

Getting ready for maize 2018

Monday, April 16, 2018

Producing a seedbed

As a result of the wet, cold and snowy conditions throughout so much of the country during February and March, establishing this year’s maize seed bed will inevitably be a challenge for many.  The good news is that if fields have been ploughed there should have been sufficient frost action to enable the generation of a seedbed without resorting to the power harrow.  The aim has to be to develop a seed bed that allows roots to get down to depth quickly, without hindrance of pans which can result, as a consequence of using power harrows in the wrong circumstances.

MGA Trials programme 2018

Monday, April 16, 2018

Last week saw the approval of the 2018 MGA research programme, the field work of which will take place during the upcoming growing season.  Results will be presented at the next MGA conference (2019).  The results for the 2017 trials are now on line.

What and why? – Using data from last summers membership survey and consultation within the MGA council, Simon Draper has coordinated the production of a set of Research Proposals which have been sent to  contractors for quotations.  Quotes are now in and tenders offered. 

During 2018 we propose to run trials ranging from weed control to crop nutrition.  The MGA research programme runs alongside work being undertaken on behalf of the British Society of Plant Breeders BSPB (partly funded by the MGA) into maize variety testing and disease tolerance.

Undersowing Maize - CSF Case Study No2

Sunday, February 25, 2018

With support from Catchment Sensitive  Farming (CSF) we have revisited research, demonstration and advisory work done along  with CSF over recent years and produced case studies summarising the key lessons learnt.   

This Case Study focuses on undersowing maize to retain nutrient and soil over the subsequent winter period. 

MGA Eyespot update

Friday, July 21, 2017

Eyespot can be identified on the crop in the initial phases as nail head sized, circular brown spots surrounded by a yellow halo. The spots coalesce and join up with adjacent lesions, to eventually cause the whole leaf to turn brown and die.

MGA Cover crop trial results

Friday, July 21, 2017

With whole crop barley and rye harvest completed and wholecrop wheat underway for many growers there is a good opportunity to grow a catch or cover crop and benefit from extra grazing or improvements to soil organic matter and nutrient retention.

Key to success is treating the cover as a crop and drilling it properly rather than spinning it on and hoping that it rains and the seed chits and grows. Some early nitrogen can also kick the crop on and ensure good early growth if field nutrient status is low.
