Research and development into new fertilizers and biostimulants
A Spanish university research group has extensive knowledge and experience in the development of new fertilizers, biostimulants, iron chelates and inductors for plant defense system. It also has plant growth chambers, greenhouses and scientific-technological equipment to carry out different types of analysis. They offer their know-how to companies interested in developing R-Y-D-Y-I projects via research and/or technical cooperation agreement.
The Spanish research group is composed by a young and multidisciplinary team committed to finding the most appropriate solutions to problems and technical needs related to the agricultural chemistry, such as scientific and technological solutions:

· Improving plant nutrition.
· Optimization of plant growth.
· Plant physiological action of biostimulants (humic substances and amino acids) and its impact on the mobilization of nutrients in the soil.
· Study of effectiveness of chelates of micronutrients, especially iron.

The main research lines of the group are:

1) Biostimulants: any improvement in the agricultural system that produces an increase in harvest should reduce the environmental impact of agriculture and improve the sustainability of the system. In the last years, there has been widespread the use of biostimulants obtained from different organic materials, such as peptides, amino acids, polysaccharides, humic acids, phytohormones, seaweed extracts... They can be absorbed by plants and soil microorganisms, developing a positive effect not only on growth, but also on quality and crop production. The purpose of these products is not provide nutrients but enhance and stimulate plant metabolism and reducing the effects of abiotic and/or biotic stress on plants. It is leading to the development of new biostimulants by the industry. In addition, these products are developed with an initial idea: to reduce the environmental impact of agriculture.

2) Development of inductors for immunological system in plants: the mechanisms of plant defense against pathogens and pests has revealed the existence of defense systems based on the recognition by membrane receptors or intracellular molecules characteristic of pathogens, which determines the activation of inducible defense barriers. These defense mechanisms are systemic, i.e. not only activing the tissue where the recognition of the pathogen/pest occurs, but also in the rest of the plant that has not been exposed to the infection. This systemic response protects the plant against further attack of pathogens/pests. This property has a very interesting potential in agronomic application.

3) Improving the effectiveness of chelates of micronutrients (particularly iron): iron chlorosis traditionally has been the main nutritional disorder in crops grown in calcareous soils, although the effects of the lack of other micronutrients as zinc and manganese must be also considered. These deficiencies are particularly important in fruit and vegetables, causing losses in plant growth, harvest and quality loss in crops. In these cases, the micronutrient application to the soil or foliarly becomes practically mandatory. For iron, synthetic chelates, especially FeEDDHA have been the most effective solution, however its low biodegradability in soil, it has sparked interest in finding solutions equally effective, but sustainable. In recent years, research on correcting micronutrient deficiencies have focused on three ways mainly:

· Development of new fertilizers (including controlled release fertilizers, compatible fertilizers with the environment and development fertilizer with high purity).
· Study implementation strategies.
· Development of new analytical methods more specific and sensitive than iron (including NMR).

The research group offers this know-how to companies interested in developing R-Y-D-Y-I projects, specific training related to the research, and any scientific and technical support via research and/or technical cooperation agreement.
Advantages and Innovations:
· Novel biostimulants products for crop enhancement on horticultural an agricultural crops grown in countries worldwide: new combinations of organic waste are being investigated (e.g. different fractions of humic substances) with the aim of discovering the synergistic effect they have on the stimulation of plant growth for improving crop yield, quality and abiotic stress tolerance, compared to the same compounds separately.

· Inducers of the immune system: several substances are being investigated (e.g. silicon, chitosan, botanical extracts and plant residues rich in antioxidant compounds) under abiotic stress (high temperature, drought, salinity, water excess, nutritional disorder...) to activate self-defense system of the plant, in order to resist future pests more efficiently.

· Improving the effectiveness of chelates of micronutrients, especially iron: the only approved chelates approved by the European legislation are not biodegradable. In this sense, the research group is looking for new chelates from organic compounds with biodegradability properties in order to reduce the amount of non-biodegradable chelates by other alternatives which endogenous iron. Moreover, both ferric nutrition and growth are being improved by these new chelates.

For the development of these different research lines the group has:

1) Plant growht chambers of seedlings in conditions of light, temperature and humidity controlled. This type of camera is best suited for short essays.

2) Greenhouse for longer experiments. It is also possible to control all growing conditions.

3) Technical Services Research of the University, with the main analytical techniques and the most modern equipment:
· High performance liquid chromatography (HPLC)
· Emission spectroscopy inductived coupled plasma (ICP-OES)
· Thermal analysis (TG, DTA)
· Mass spectrometry (MS)
· Elemental analysis
· IR and UV spectroscopy
· Microscopy Unit
· Nuclear Magnetic Resonance (NMR)
· X-Ray Analysis
