Are you getting your sulphur strategy correct? Ensuring an adequate supply through the growing season could be key to ensuring these other nutrients are taken up efficiently also

Establishment is the most critical period in any annual crops life-cycle, as it is the time when the yield potential is set. All challenges the crop faces during the season serves to reduce the final yield from this potential. pda.org.uk/establishment-and…
The theory of utilising catch or cover crops for nutrient cycling is sensible. These plants will pick up nutrients from the soil which may otherwise be at risk of moving down the profile following rainfall

There's always pressure on cereal farmers to reduce costs. Basal P&K are particular targets because reductions in use that damage yield, or increase susceptibility to stress, may have little or no visible short-term effect. pda.org.uk/pda_leaflets/11-p…

Potash affects both yield and quality of grain as well as the general health and vigour of the plant. Cereal crops need at least as much, if not more, potash than any other nutrient including nitrogen

Great paper from the @FertiliserSoc on the importance of K on plant stress. More on the PDA website too pda.org.uk/videos/potassium-…
IFS 711 describes the Role of Potassium and Magnesium in Mitigating Abiotic Stress in Crops. This figure shows how K helps to regulate leaf stomata opening and closing through turgor changes. This is hindered by Mg deficiency. More info: buff.ly/3HaDTlT

All set for the #CropTec22 show tomorrow. Visit us at stand 2.104 in Hall 2 to discuss all things K including it’s effects on NUE

For nutrition, soil pH is the starting point, as availability of all nutrients are affected by soil pH. The optimum availability of nutrients occurs around a neutral pH of 6.5 to 7, however optimum pH for soils varies by soil type & cropping. Read more... ow.ly/2qwQ50LrJqP
One of the defining memories of the 2018 harvest was the pink straw. Pink straw is back, and once again we have had a dry spell, high light intensity & heat. These abiotic stresses lead to increased levels of anthocyanins, giving straw a pink colour ow.ly/wb4y50Kbz3l
Due to current financial pressures P&K use may be cut-back. Replacement is increasingly costly and difficult to catch-up the longer its left. The biggest effects are those crops that need most K or have poor root systems. ow.ly/hBMa50K4hac
Sulphur is an important nutrient for plant growth and development. Due to the central role of both S & N in the synthesis of proteins, the supplies of these nutrients are highly inter-related. A shortage in the availability of S will reduce NUE ow.ly/pLSk50JtwSI

Cost and price rises are a frequent focus in the world right now, especially within agriculture. However, if P or K is not available or the rate of supply is limiting, plant performance will be impaired leading to lower yields and poorer quality ow.ly/CmGh50Je8xI
Sugar beet is an increasingly important crop providing an essential break to weed, pest & disease. Ensuring adequate nutrition for rapid early canopy growth is a key focus area for improving mature plant resistance to virus and early light interception ow.ly/NwBl50IrHhI
The current N price sharpens the focus on making best
use of this input. With this in mind, the interaction between N&K cant be ignored. ow.ly/j0ZV50HhwSi

Soils often contain total quantities of nutrients in excess of the amounts immediately available to plants. Two ways of increasing availability in soils have previously been suggested, however, neither have any reasonable chance of success. pda.org.uk/the-release-of-nu…
Farming Rules for Water hit the spotlight last month due to concerns regarding their interpretation by the EA. Fully accounting for nutrients supplied by manures is a message the intustry has long been pushing for, although practicality cannot be ignored pda.org.uk/farming-rules-for…

Recently highlighted @PDA_Potash data shows a potentially high number of arable fields are not receiving sufficient PK, which is resulting in declining indices

Sugar beet has a large requirement for K, largely taken up during the early months of growth. K transfers sugars produced in the leaves to the root. Each sugar molecule has to pass through many cell membranes, using K+ ions to facilitate this passage pda.org.uk/sugar-beet-nutrit…
Nutrient use efficiency is a talking-point currently as government considers ways to reduce the impact of agriculture on GHG emissions. This month’s newsletter takes a look at ways to improve NUE through balanced applications & improvements in rooting ow.ly/W27g50E0BWs
