Inside the Lab: A New Patented Root Stimulant to Replace Phosphites

https://eutrema.co.uk/shop/soil-conditioners/magnesium/ Dr. Russell Sharp explains why magnesium is vital for plants — it sits at the centre of chlorophyll — and how deficiency leads to interveinal chlorosis, reduced photosynthesis and lower yields. He outlines common causes such as calcium and potassium antagonism, and why symptoms often appear first on older leaves. The episode gives practical diagnosis tips and corrective options: CalMag and Magnesium Plus for hydroponics and lawns, Epsom salts for fruit crops, liquid gypsum for toxicity, and guidance on proactive applications to prevent problems and improve plant colour and performance.

Dr. Russell Sharp examines the key threats to fertiliser and pesticide prices in the UK looking toward 2027, including rising energy costs, sulphur and phosphate supply disruptions, geopolitical conflicts, and potential sanctions. He also explains the likely effects of the UK carbon border adjustment mechanism, the feedback loop between crop prices and fertiliser demand, and how regulatory harmonisation could wipe out small biostimulant and hydroponic suppliers. The episode outlines consequences for arable farmers, sports turf, lawn care and hydroponic growers and highlights what to watch for in the coming years. https://eutrema.co.uk/

Dr. Russell Sharp explains Eutrema’s Periodic Table of Plant Health, a handy poster included with orders that groups essential and non-essential elements and explains their roles in plant nutrition. This episode walks through macronutrients (NPK), secondary nutrients, micronutrients, non-mineral needs (CO2, H, O), beneficial extras like silicon, toxic elements to avoid, and practical tips for lawn, turf, arable, and hydroponic growers — plus info on freebies and resources from Eutrema. https://eutrema.co.uk/plant-health-periodic-table-poster/

Dr Russell Sharp reviews recent weather impacts on crops, lawns and hydroponics, announces a Black Friday humic acid offer (code HUMIC15), and explains how wetting agents and soil moisture matter after drought and heavy rain. He introduces an upcoming food‑grade, biodegradable root stimulant designed to replace potassium phosphite, outlines plans to patent it, and describes required testing across diverse plant species plus greenhouse and split‑pot trials. Also covered: new tank‑mix compatibility chart on the Eutrema website, sample and trial opportunities for small growers and turf managers, and upcoming events like Grounds Fest.

Dr. Russell Sharp explains why his company doesn’t sell microbial products, citing viability, supply-chain dilution and poor-quality suppliers that damage the sector’s reputation. He announces a free service for regenerative farmers: send recent microbial products to Eutrema for microscopy, staining and culture tests to verify identity, viability and concentration, with results shared to help clean up the market. https://eutrema.co.uk/shop/pesticides-organic/chitosan-biofungicide/

Dr. Russell Sharp explores perennial arable crops such as kernza, perennial rice, and sorghum; discussing their advantages (reduced tillage, deeper roots, soil health), current commercial status, and practical challenges such as lower yields, pests, and multi-year management. The episode also covers breeding and gene-editing targets to improve traits, global research efforts, and the potential for growing perennials in hydroponic systems and niche value markets. https://eutrema.co.uk/ Norman Borlaug — CIMMYT Sanjaya Rajaram — CIMMYT Surinder Vasal — CIMMYT Ravi Prakash Singh — CIMMYT Neelamraju G.

Dr. Russell Sharp examines fertiliser products that claim to contain dozens to 90+ chemical elements, using the periodic table to show why many of those claims are impossible, radioactive, or potentially toxic. He explains that plants only need around a dozen essential nutrients (plus a few beneficials), points out which elements can’t realistically be present, and urges listeners to question manufacturers and check ingredient lists. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Croptec Cereals Diddly Squat Farm Jeremy Clarkson  

In this episode Dr. Russell Sharp explains trehalose 6‑phosphate (T6P) as a plant sucrose‑status signal and its potential to boost wheat yields. He compares products from SugarRox and Unium, discusses trial evidence, ROI claims, and the challenges of bringing a single‑compound biostimulant to market. Dr. Sharp also covers intellectual property and public‑sector spinouts, the need for larger independent field data, and why farmers may view biostimulants as optional investments. He finishes with notes on upcoming industry events and calls for more transparency and real‑world results. https://eutrema.co.uk/category/biostimulants/

Dr. Russell Sharp examines the severe crop losses in Latvia caused by heavy spring and late-season rainfall, flooding and seed washout that destroyed vegetables like onions, carrots, cabbages and potatoes. He explains how these conditions have left farmers facing large economic losses and likely increased imports and prices. The episode contrasts Latvia’s wet, unstable “climate frontline” with the UK’s recent drought conditions, touches on Estonia’s high organic output, and asks listeners for feedback on which season they prefer. https://eutrema.co.uk/shop/biostimulants/potassium-silicate-20-litres/
