P and K blog series: The building blocks of overall plant health

Thursday, 25 June 2020

SOYL My Technical Blog

Phosphorus and potassium are vital for photosynthesis and water regulation – but how much of them do you need to guarantee healthy plants?

Precision technology can play an important role when it comes to successful nutrient management. With P and K in particular, there is a considerable benefit to carrying out nutrient mapping and variable rate applications of fertiliser in that you are able to individually deal with field areas that are both below, at and above the critical level.

Creating your own seed rate trials using MySOYL

Monday, 09 September 2019

Simon Griffin

SOYL MyFarm

Choosing the seed rate is a crucial decision that every grower has to make before drilling, but how can you ensure you're using the optimum rate for your field? As well as the usual calculation, SOYL's MySOYL application – available as part of Frontier's MyFarm farm management platform - can help you to conduct specific trials to gain a bett...

How can precision help guide nitrogen applications on milling wheat?

Wednesday, 29 May 2019

Simon Griffin

SOYL

Many people might assume that yield is the best indicator of whether they have got their nitrogen applications right. However, a better indicator is the protein level in the grain. Grain protein Grain protein with optimum nitrogen for yield in feed varieties is consistently about 11% (1.9%N). Bread making varieties optimise for yield at around 12% ...

Story of a field

Tuesday, 26 February 2019

Simon Griffin

SOYL

There has been a lot of interest in variable rate nitrogen this season driven by crops that are full of potential, and good market prices. SOYL's variable rate nitrogen service, based on reliable satellite imagery, has proven yield and protein benefits. One way of showing how we achieve these improvements is to show visually how the crop responds t...

Satellite imagery – more than just Variable Rate Nitrogen

Friday, 25 January 2019

Simon Griffin

SOYL

The benefits of using satellite imagery go way beyond the yield improvements that have been seen from variable rate nitrogen applications. Some of these advantages will be picked up in more detail by other blogs but to start, I thought it would be useful to share other opportunities for the use of satellite imagery and the added value that can be d...

What is the best phosphate product?

Thursday, 17 January 2019

Simon Griffin

SOYL

The use of phosphate fertilisers has always caused more confusion than other nutrients.Choice of fertiliser to give the best long and short term availability is often a topic we are asked by growers. Different forms of phosphate (such as orthophosphate or dicalcium phosphate) and the complex relationship that phosphate has with calcium, iron and pH...

We had the wind in our sails at Tillage Live 2018

Friday, 05 October 2018

Simon Griffin

SOYL

I had the pleasure of attending Tillage Live 2018 last week. This year, the event was held in Dunbar, East Lothian and although SOYL have always supported the event, it had been of couple of years since I'd been myself. I was really looking forward to exploring the site, talking to lots of attendees and seeing the impressive demonstrations on show....

Get the most from your yield map data

Thursday, 04 October 2018

Simon Griffin

SOYL

Imagine if there was a way to automatically know which areas of your production system are most profitable and those which are loss-making. Wouldn't it be great to know which management decisions had paid off, which new methods of working had or hadn't worked and if all of this information could be collected with minimum effort? For farmers that ...

Over-winter nitrogen losses and spring N levels

Tuesday, 01 May 2018

Simon Griffin

SOYL

SOYL have undertaken a nitrogen sampling project at a number of sites across the UK. These sites had a range of differing soil types, allowing us to assess over-winter changes in soil nitrogen levels. A comparison of nitrogen levels in March, compared with those measured in November, has shown a significant over-winter loss, averaging 50kg/ha N or ...

Variable rate plant growth regulators (PGRs)

Friday, 23 March 2018

Simon Griffin

SOYL

SOYL have been conducting trials using variable rate plant growth regulators (PGRs) on both winter oilseed rape and winter wheat. The premise for variable applications on both crops is the same – that there will be a yield benefit from applying a full rate of PGR on crops that are at risk from lodging because of over-large canopies. However, if the...

Precision farming and grassland

Thursday, 22 March 2018

Simon Griffin

SOYL

Over the past few seasons, SOYL has been developing precision farming services for the grassland industry. Grass is the UK's largest crop and is grown in every county. A particular area that became a focus was that of pasture management and we discussed this during our winter workshops. A grassland and livestock famer needs to make constant decisio...

Why and how would you do your own late-November plant counts?

Tuesday, 21 November 2017

Simon Griffin

SOYL

During germination a proportion of viable seeds can fail to emerge due to pests, diseases and soil conditions, impacting the total viable plants in the spring. Conversely, too high a plant population can increase canopy size (GAI) and reduce the ability of individual plants to compete for light and resources, meaning there will be fewer grains on e...

Review of the European Conference on Precision Agriculture

Friday, 28 July 2017

Simon Griffin

SOYL

As the head of SOYL's technical and R&D department, one of my responsibilities is to look at the latest developments in precision agriculture research and keep an eye on the 'next big thing' for customers. To find out more about what's happening in the industry and to share more about SOYL's own work, some colleagues and I went to Edinburgh ear...

What should I do with straw this harvest?

Tuesday, 18 July 2017

Simon Griffin

SOYL

As SOYL's technical manager, I'm responsible for our crop nutrition strategy and at this time of year, many clients and colleagues ask me the same question: should I remove my straw and sell it? Dealing with straw on the farm can be complicated. For some, it's a valuable soil management tool or a source of income and for others, just a proble...
