OPTIYIELD PRODUCTS
OptiYield Foliar Fertilisers, Biostimulants & Crop Nutrition Products
OptiYield® products are designed to support crop nutrition, nutrient use efficiency, root development, stress tolerance and marketable yield in potatoes, vegetables, cereals and other high-value crops. The range includes foliar fertilisers, foliar nutrients, biostimulants, seaweed extracts, organic acids and microbial products used within full-lifecycle OptiYield crop programmes.
Developed through Emerald Research’s field experience, research and on-farm trials, OptiYield products help growers target key growth stages with the right nutritional and biological support, reducing waste while improving crop performance. OptiYield programmes have delivered 10–25% marketable yield increases in high-value crops.
MagPi –In-furrow starter nutrition for potatoes
OptiMol – Foliar Molybdenum
A high-availability source of molybdenum for foliar application.
Foliar Nitrogen Availability Update – We have secured a limited volume of Folia-N for early May delivery for our customer base. For further information or to discuss availability, please contact Simon on 01242 506206.
Establishing a strong potato crop starts at planting. MagPi, Symposium and SuperPhos work together to deliver targeted nutrition and early crop support, helping drive root development, canopy growth and strong tuber initiation.
Biostimulants and Microbials
Products: BioBoost, Diamond, SeaSpray, Symposium, SeaSpray Xtra, Activator.
OptiYield biostimulants and microbials are designed to support crop establishment, root growth, nutrient uptake, stress tolerance and overall crop vigour. These products can be used as part of tailored programmes for potatoes, vegetables and arable crops.
SeaSpray 100% Cold Pressed Natural Seaweed Extract
Activator Organic Acids & Biostimulants
Foliar Nutrients
Foliar Nutrients and Foliar Fertilisers
Products: SuperPhos, MagPi, Folia-N, Aqui-S, OptiPot, OptiMag, OptiMan, OptiMol, OptiBor, BoriMol, Chroma, Spectrum, Prism.
OptiYield foliar nutrients provide targeted nutrient delivery at important crop growth stages. Foliar application can help supplement soil-applied inputs and support nutrient availability when root uptake is limited by soil, weather or crop stress conditions.
MagPi – In-furrow starter nutrition for potatoes
Aqui-S Foliar Sulphur
Foliar Sulphur to correct sulphur deficiency and promote growth.
OptiPot Foliar Potassium
A high-availability source of potassium for foliar application.
OptiMag Foliar Magnesium
High efficiency, highly concentrated foliar magnesium designed to supplement soil-applied inputs.
OptiMan Foliar Manganese
High efficiency foliar Manganese designed for essential micronutrient crop support.
OptiMol – Foliar Molybdenum
A high-availability source of molybdenum for foliar application.
OptiBor– Foliar Boron

Foliar Nutrients
Foliar fertilisers are designed to be applied directly to the leaves of a plant. Plants are able to absorb essential elements through their leaves.
OptiYield Macronutrients and Micronutrients are developed to complement and, in many cases, replace soil-applied fertilisers.
Due to the significant increase in efficiency and efficacy of OptiYield products, farmers can dramatically reduce the amount of overall fertiliser inputs they use. This meets one of the FAO objectives to reduce the overall environmental impact and carbon footprint of fertilisers.
OptiYield products are available in liquid and powder form and their unique formulations are designed to provide optimal penetration and mobility of the nutrients within the plant and can be tank-mixed together with other OptiYield foliar nutrients and biostimulants as well as third-party crop protection products.
Biostimulants
OptiYield 3rd Generation designer biostimulants are developed from research and investigation of 1000's of natural materials using fundamentals of biochemistry
Biostimulants are defined as:
“A non-fertiliser material containing substance(s) and/or microorganisms applied to plants or the rhizosphere whose function is to stimulate and benefit natural plant development processes embracing nutrient uptake, nutrient efficiency, crop quality, crop vigour, resistance to or tolerance of external environmental stresses.”
OptiYield 3rd Generation designer biostimulants are developed from research and investigation of 1000’s of natural materials using fundamentals of biochemistry including researching/measuring gene regulation and expression technology, and based on funded research with lab assays, pot and independent replicated field trials.
We are now turning our attention to the next generation of biostimulants and integrating these with foliar nutrients and microbial applications through the lens of the OptiYield system.
Microbial Biostimulants
Soil health is impaired both by poor cultivation/rotation practices and overuse of input factors such as fertilisers, fungicides, nematicides and insecticides.
Long-term use of some soil-applied broad-spectrum fungicides and pesticides can put continued pressure on soil biology, reducing the population and biodiversity of the wider beneficial microbial community.
Research into reversing this trend has shown benefits in promoting crop/microbe associations through inoculating soils with beneficial micro-organisms, developing crop varieties that better associate with soil micro-organisms and investigating optimal soil management regimes (e.g. crop rotations, inter-cropping and reduced-tillage) that promote beneficial microbial biodiversity.
OptiYield microbial formulations have proven themselves to be exceptionally effective, especially when used as part of an overall OptiYield programme.
