Agrophysics as a branch of science applying physics to the investigations of properties of materials and the processes involved in the production and processing of agricultural products, especially in relationships between soil, plant, atmosphere and soil, plant, machine, agricultural products. Particular attention is given to sustainable plant and animal production, modern agricultural technologies, and quality of raw materials and food products. The scientific activity of the Institute concentrates on studies of physical properties and processes important for proper management of soil environment and development of sustainable agriculture and food production. It covers also elaboration and improvement of specific methods of physical measurements, computer modeling and monitoring. Monitoring equipped with appropriate measuring systems constitutes a basic tool in study of the environment. The Institute develops agrophysical metrology that takes care on elaboration, optimization and standardization of agrophysical measuring methods. Modeling and computer simulation concerns environmental and technological processes as: mass and energy exchange in soil-plant-atmosphere system and agricultural products, regulation of physical, physicochemical, hydrophysical, thermophysical and biological properties of soil and plant structures, optimal fertilization systems, physical characteristics of granular materials (soils, grains, flour) as well as physical aspects of agricultural products processing.

It plays an important role in the limitation of hazards to agricultural objects (soils, plants, agricultural products and foods) and to the environment. Soil physical degradation, gas production in soils and emission to the atmosphere, physical properties of plant materials influencing their technological and nutritional values and crop losses are examples of such hazards. Agrophysical knowledge can be helpful in evaluating and improving the quality of soils and agricultural products as well as the technological processes.

  • Role of Agrophysics in Sustainable Agriculture Rôle De L'agrophysique Pour L'agriculture Durable
    Scientific registration n° : 517 Symposium n° : 20 Presentation : poster Role of agrophysics in sustainable agriculture Rôle de l'agrophysique pour l'agriculture durable GLINSKI Jan Institute of Agrophysics, Polish Academy of Sciences, Doœwiadczalna 4, P.O.BOX 201, 20- 290 Lublin 27, Poland An example of application of physics in the development of knowledge in other branches of natural sciences are: astrophysics, physics of atmosphere, environmental physics and geophysics. The development of environmental physics is very important for mankind due to its relevance to a direct description, modelling and prediction of human environment. Agrophysics is an integral part of environmental physics and it deals with the processes in agricultural used lands [1]. Such areas cover only 9.7 % of global Earth surface, however, they are under intensive human ingeration, e.g., monoculture crops, water management and high level of chemical and mechanical treatment. Agrophysics is also occupied in investigating of physical and physicochemical processes connected with mass and energy exchange in soil- plant- atmosphere system and the processes related to gathering, transport and storage of agricultural plant materials[2,4,8,11,13,14]. In agrophysics, like in other natural sciences, the fundamental method of description of investigated objects and physical phenomena and processes taking place in them is modelling. Knowledge of physical properties of the soil-plant-atmosphere system and their time and space variability allows physical model development for simulation and prognosis of evolution of environmental conditions in time [10]. Developed models make possible to prognoses the human environment change due to global climate change and human activity (land use, food production, etc.).
