Description of the research

Soil fertility. Effects of fertilizers on the chemical, physical and biological properties of soils.

• Exchangeable nutrients, bioavailability for plants.
• Dynamic measurements of organic nitrogen and carbon mineralization (FD U44-163).
• Determination of product effect on soil pH by incubation (NF EN 14984).
• Physical properties of soils (compaction, penetrometry, water retention capacity, stability of aggregates).
• Biological activity (respirometry) and living microbial biomass of soils (fumigation-extraction).
• Biodegradation of agricultural plastics in soil

Mineral nutrition of plants. Growing media and fertilizers effect on plant growth and mineral absorption.

• Transfer of minerals from soil to plants
• Application of foliar fertilizer
• Study of nutrient deficiency symptoms in plants.
• Biomass production and quality parameters (protein and sugar concentrations, etc.)

Plant – Environment interactions. Effect of the different growth factors on plant morphology, physiology and productivity.

• Root system architecture in response to nutrient concentration in soils.
• Light quality and artificial lighting scenarios for plant growth (LED technologies)
• Biostimulants and growth regulators
• Germination and phytotoxicity tests
