Biogas

Maize silage has been shown to be one of, if not the, best agricultural feedstocks for biogas production.  When mixed with other organic wastes or used alone maize based biogas production has proved to be economic across Europe.  MGA Biogas related information aims to provide growers with biogas specific advice on variety choice, agronomy and digestate recycling.

Key maize growing issues

Simon Draper gives us an update on maize growing issues this year, including whether to plough or not, what sprays are available, seed rates and fertiliser requirements.

Maize under plastic in South Devon

Wednesday, May 22, 2013

A visit to Graeme and brother Patrick Cocks farm nr Ashburton in Devon confirmed one of the key benefits of establishing maize under plastic. 

Graeme and his team were cultivating and drilling maize on the April 5th being able to take advantage of the dry if not cold conditions to get crops in the ground almost a month before many would consider establishing maize without film cover.

Drilling maize this spring

Monday, March 25, 2013

As you all know maize does not like compaction of any sort and so it is going to be a challenge to try and get a reasonable growing medium in many fields. This technical note will, hopefully give you some ideas as to how to go about producing a viable seedbed for this year’s crop.  Finally, a word of caution as each field should be treated individually, please take the enclosed suggestions as general rather than definitive advice.

Lessons learnt from 2012

Nitrogen Predictor form

Monday, January 14, 2013

Variety choice made, the next thing on the maize 2012 list will be how much fertiliser will the crop need?  With this in mind, we would encourage members to use the MGA Nitrogen Predictor to calculate their bagged fertiliser nitrogen requirements.  

The Nitrogen predictor, originally designed ten or so years ago takes into account location, soil conditions, target drilling and harvest dates, as well as the nutrient content of any manures applied, to come up with a bagged nitrogen requirement for the crop.  The predictor is well proven over time, with farmer feedback over the years being used to update the original research based systems. 

The predictor has also been used by farmers to justify their nitrogen applications to NVZ inspectors and therefore, goes some way to meet the NVZ record keeping requirements.  Fill in and return the enclosed N predictor input form to get the ball rolling.

Harvesting maize in a difficult season

Monday, October 22, 2012

Maize in the drier and warmer eastern half of the country is generally average /good and harvest is now underway.  In the west a different story has developed, with many crops having struggled for a multitude of reasons from drilling.

With such a contrast in conditions and crop growth stage, working out the right date for harvest will be very difficult.  This task will be particularly difficult for growers with stunted crops, which may or may not have a viable cob. 

The good news is that the warmer weather of September has advanced crop maturity in all areas and even many of those with stunted crops now have cobs, which given time will lay down starch.  Ironically if the starch is laid down in these stunted crops, then overall maize quality could be good.  Yields will of course be down considerably.

The advice here is to 'wait as long as you dare' to ensure that the cobs have as much starch in as possible. That said, it cannot be forgotten that delaying harvest is not generally a good idea, as poor harvest conditions and frost can cause as much of a yield loss as is trying to be gained by delaying the harvest for maximum starch yield.

How much maize have I got

Saturday, July 7, 2012

John Morgan has produced a "guide" to working out what yield to expect from your maize this year.  This involves counting plants and estimating the yield.

How much maize have I got?

Saturday, July 7, 2012

The cold and wet weather during the spring and summer has put many maize crops under pressure with concerns now being raised as to the yield and quality of the forage that will be harvested.  With options of home grown or even purchased wholecrop still available now is the time to work out where you stand.

 How much maize will I get?

This year’s maize yields are under threat due to the cold and wet conditions.  Early drilled maize, where it got away before the rain, has to a large extent stalled.  That drilled early into soils that have subsequently capped has struggled to breakthrough with plant populations severely hit in some cases.  Later drilled maize has avoided the early pitfalls but it is also struggling to grow in far from ideal conditions.  All the above will at best delay maize harvest but in many cases will also impact on crop yield. 

Maize not germinating - time to panic?

Thursday, May 3, 2012

With a lot maize drilled into the good conditions in early April and with the following wet and cold weather, the maize unsurprisingly is very slow to get going.

 Simon Draper gives us some useful advice for drilling in these wet conditions.

Cold & Wet - Ideal conditions for maize?

Simon Draper talks about the conditions this spring and gives advice on what we should be doing, whether we have already drilled or are waiting for conditions to improve.
