Good human health not only requires enough calories, but also sufficient intake of all essential nutrients.
Traditionally, fertilisers have been used to maintain or restore soil fertility, increase crop yield and to a lesser extent, improve crop quality. Their management has been progressively improved to optimise economic return, whilst minimising negative impacts on the environment.
More recently, there is increasing attention to another dimension; managing fertilisers, in such a way, that they also contribute to healthy and productive lives for all consumers.
RLF. 25+ Years of Plant Nutrition.
RLF Specialty Liquid crop nutrition fertilisers have been developed, manufactured and continually refined over a period of more than 25 years to a position today where our products are targeted to provide the nutrition needs of any particular crop, or for any particular deficiency. Balanced crop nutrition, by supplying all essential nutrients is a generally recognised, cost effective fertiliser management strategy. We are playing our part to assist the world’s agricultural sector transition to more efficient, productive and restorative practices to ensure a continued safe and nutritionally healthy food supply.

All biological systems depend on essential nutrients in balance to thrive. Lack of any one nutrient will lead to loss in productivity, disease states, and ultimately death.
Nearly all human food systems on earth are dependent on agriculture as their primary supplier of nutrients. If agriculture cannot provide adequate amounts of all nutrients, these food systems become dysfunctional and malnutrition ensues. The question of how agriculture can best feed a burgeoning human population when faced with unprecedented challenges occupies the minds of world leaders today.
There is nothing more important than supplying all the nutrients required for good health, felicity, and longevity of the human race. The sustainable means to this end must come from agriculture. Malnutrition, including trace element deficiencies, is the result of dysfunctional food systems based in agricultural systems that provide the nutrients to feed the world. Thus, farmers should be thought of as nutrient providers.
It is imperative that agriculture be closely linked to human nutrition and health and that fertiliser technology be used to improve the nutritional quality of staple food crops.
Humans require at least 10 essential trace elements (Boron, Copper, Fluorine, Iodine, Iron, Manganese, Molybdenum, Nickel, Selenium and Zinc). The foods produced from farmer fields are the primary suppliers of these nutrients.
Micronutrient malnutrition (which includes both trace element and vitamin deficiencies) is the result of dysfunctional food systems based in agricultural systems that do not meet all human nutritional needs. Agricultural tools can be used to address micronutrient malnutrition.These tools include the biofortification strategies of plant breeding and use of trace element fertilisers.
Biofortification is a name given to agricultural efforts to improve nutritional value of food crops (staples, mainly). The primary effort is through plant breeding, both conventional and biotechnological, but nutritional value can also be improved by the use of trace element fertilisers.
Fertiliser technologies for biofortifying staple food crops (frequently referred to as agronomic biofortification) with essential trace elements have been ‘on the shelf’ for decades, although a more recent technology, fluid fertilisers, may be an important advance that will benefit both yield and micronutrient value compared to current solid fertilisers (Holloway et al., 2008).
Fertilisers can be used both to increase the yield and the concentration of specific nutrients in plant parts. Typically, in these cases, adding the more deficient nutrient results in a yield increase, and adding both limiting nutrients (assuming no others) causes a large yield increase at relatively small cost. It is costly to ignore them as they can severely limit the benefits of the costly macronutrient fertilisers used.
Any nutrient deficiency is likely to aggravate the effect of an environmental stress such as heat, cold, drought, water logging, fungal pathogens, salinity, direct drilling, topsoil drying, herbicide damage and seasonal differences such as the timing of the break of
