Dr. Russell Sharp of Eutrema explains why most gardens and sports pitches contain some clay, how the soil texture triangle works, and why liquid gypsum helps by flocculating clay to improve drainage.

He gives simple DIY tests (jar sediment test and the ribbon/ball test), recommends using soil maps or neighbor knowledge, and advises working with your soil rather than trying to change its texture.

Dr. Russell Sharp of Eutrema Ltd introduces biostimulants = substances that improve plant growth, root development, stress resistance and photosynthesis without acting as fertilizers or pesticides. He explains how they give turf an extra performance edge when nutrition and growing media are already optimal.

Common types include seaweed extracts, amino acids, beneficial microbes, humic/fulvic acids, yucca and chitosan. Practical tips: low-dose “on/off” effects, avoid storing diluted mixes that can ferment, consider compost teas, and watch for changing regulations that may affect product availability.

Dr. Russell Sharp from Eutrema explains how to treat and repair lawn damage caused by weedkillers (herbicides) like glyphosate. Learn immediate steps—applying calcium (Liquid Gypsum), avoiding phosphorus fertilizers, using activated carbon or biochar, stimulating microbial activity, removing dead turf, and reseeding—to restore your lawn safely and effectively.

Dr. Russell Sharp explains how common lawn and sports-turf weeds reveal soil conditions — from nutrient levels and pH to compaction, moisture and even metal traces. Using examples like bee orchids, fairy rings, red shank, pineapple weed, nettles and clover, he shows how to interpret these indicators and take practical steps.

He also gives simple management advice: test your soil, avoid rapid chemical changes, apply balanced nutrients when appropriate, and address compaction to restore healthy turf.

Dr. Russell Sharp describes moving from a backpack sprayer to a 100L tractor-mounted unit for his village sports field, sharing why he upgraded and what he hoped to achieve.

He recounts a series of problems—dead batteries, snapped wiring, accidental fertilizer spills, a failed pump, and mismatched replacement parts—and how each issue caused delays and messes.

Russell offers simple takeaways: test equipment before filling, keep spare parts and a portable battery or inline switch, and consider investing in a higher-quality, higher-capacity sprayer once you understand the challenges

This episode explains what anaerobic digestate is, how it is made, and why it is increasingly used in fertilizers for lawns and sports turf.

Dr. Russell Sharp discusses the benefits (fast-acting ammonium nitrogen, organic carbon, low cost) and the risks (strong odor, scorch, variable nutrient content, contamination, and poor performance on compacted soils), and gives practical recommendations on when to consider or avoid digestate-based products.

Dr. Russell Sharp breaks down why moss thrives in lawns and sports turf, explains Eutrema’s updated Ultimate Iron fertiliser, and compares iron sulfate with premium chelated iron.

He covers practical control methods, cultural fixes like scarification, better irrigation and aeration, and alternatives such as silica and wetting agents, plus why repeated iron sulphate use can harm soil biology.

Dr. Russell Sharp returns to the Grass Me Up podcast with updates from Eutrema’s new HQ, rapid business growth, and successful results using Liquid Gypsum on sports turf.

He covers new product launches (a fungal amino acid and Phosphorus Liberator), hands-on work at local pitches, and concerns about upcoming UK fertiliser registration rules that may impact small suppliers.

Expect more science-led episodes, practical turf solutions, drone footage, and invitations to visit the new studio.

Dr. Russell Sharp explains what glyphosate (Roundup) is, how it works as a systemic non‑selective herbicide, and why it remains widely used in turf care and agriculture.

The episode covers controversies and legal cases, the misuse of LD50 data, environmental persistence, effects on soil micronutrients and microbial communities, and emerging resistance in some weeds.

Practical advice is given on safe application timing and PPE, treating accidental herbicide damage, the company history and product variants, Eutrema's Ivy Pre‑Spray, and future tech possibilities like micro‑spray robo‑weeders.

Many pre-plant granular fertilisers share a 6-9-6 NPK because a few UK manufacturers produce bulk granules and white-label them for multiple brands, creating an illusion of choice. Granules are cheap to make, often contain chloride salts that can cause leaf scorch, and can stick to leaves if moisture is present. Liquid fertilisers, while requiring a sprayer, offer greater flexibility, plant-available ingredients like silicon, and allow mixing with biostimulants. If buying granulars, compare NPK ratios and appearance to spot likely white-labelled products.
