Potash News

The Potash Development Association publishes both technical Potash News items and shorter Blog items. Potash News provides the latest up to date information on Potash and its use, while blog items are shorter and more timely.

If you are in the UK or Ireland and are interested in receiving Potash News items through the post free of charge, then sign up on the contact page. Recipients of the Potash News can receive CPD points for BASIS, NRoSO, and Dairy Pro.

Potash for OSR

August 2020

Oilseed rape is going through a tough period at the moment, rapidly falling out of favour on-farm due to difficulties with establishment following the loss of neonicotinoid seed treatments in 2014. On top of this it has also faced increasing challenges with Clubroot, Turnip Yellows Virus, erucic acid levels and weed control. However, despite these […]

Record rainfall impacts soil nutrient levels

July 2020

It will probably come as no surprise that the high level of rainfall seen over winter throughout most parts of the UK has resulted in lower soil nutrient levels when analysed.

Crop stress responses

May 2020

It has been stressed many times about the importance of potassium in crops suffering from drought stress, and each spring appears to provide a reminder of this.

Legumes need a good K-start!

May 2020

Potassium is an essential nutrient for legumes as it is for all crops. It is an activator for many enzymes, especially those involved in protein synthesis and has an important role in maintaining water balance in the plant. In legumes, potassium is necessary for the proper development and functioning of root nodules. In legumes, rhizobia […]

To bale or not to bale…

July 2019

With harvest having started in several counties across the country, decisions will be being made whether to bale straw or chop and incorporate back into the soil. Many winter barley crops that have not suffered from the dry conditions up to June generally have a large amount of straw. Last year there was quite a […]

Potash for maize

June 2019

Following the recent heavy rainfall, some spring sown crops will have quickly gone from a state of moisture stress to waterlogging, not ideal in the early stages of production! Some of the later sown spring crops, such as maize have been slow to get going due to the dry soil conditions. The rainfall will help […]

Potash and sulphur for silage yield and quality

May 2019

Unlike nitrogen and sulphur, potash moves very slowly in the soil. Failure to replenish the potash removed by grass cut for silage can lead to short-term yield penalties. The advice to keep soil potassium levels at Index 2- will maintain a fertile and productive soil throughout the horizon where roots can access nutrients. Fresh potash, […]

Potassium and drought tolerance

April 2019

It can be a bit of a gamble to put together an article which focusses heavily on current weather conditions, particularly when thinking back to April 2012, when farms with access to irrigation equipment were considering applications to cereals. We all know what happened next… However, it cannot be ignored that large parts of the […]

Potash for grassland

March 2019

Potash is used to regulate the movement and storage of solutions throughout plants which can be compared to the blood system in animals or humans. This is a very wide ranging and vital role, affecting nutrient uptake, photosynthesis, rate of growth and feed value of forage. These functions require larger amounts of potash in total […]

Consider nutrient removals more closely this season

July 2018

The implications of plant potash levels on drought stress are often discussed during the spring due to the role potash plays in enabling efficient water usage in plants and improving crop tolerance to drought. Drought conditions are not only related to potassium levels in the plant but may also have an impact on nutrient levels […]

Time to reflect on last year’s yield and nutritional program

January 2018

Winter is a good time for many to reflect back on last year’s yields and nutritional programs to identify areas of change that may need correcting going forward. Where applications of phosphate and potash were made based on estimated yields and assumptions on straw management, actual offtakes could be very different, which unless corrected could […]

Change of PDA staff

November 2017

Our Coordinator, Peter Hoey, is leaving PDA and we are delighted to say that Ian Matts is taking over from December 1st. Ian is well known in the nutrient industry having done over 10 years with Yara Fertilisers, lastly as Technical Manager for UK and Ireland. He is now an independent agronomist/consultant, and also the […]
