Results of Long Term Fertiliser Experiments - Use in Sustainable Soil Fertility Protection Measures

Abstract

Long-term experimental research is a model for a superior approach to the long-term effects of vegetation and plant production factors, in relation to the modification of soil-plant components, their productivity, environmental protection and food security. In their fairly well-established and evaluated existence of 180 years, one can assess and record the existence of these experiments on almost all continents, with particular and relevant responses to be implemented for the development of sustainable systems in the development of agriculture and the resolution in time of contemporary challenges for both agriculture and the environment. (Recording of the 180th anniversary of the founding of the "long term model" at Rothamsted - "Three - day hybrid event hosted online and at Rothamsted Research, West Common Harpenden" UK, 20th-22nd June 2023). This paper aims to interpret the changes in the soil-plant system, based on studies and research in experimental and soil analysis field, after long term effects in the experiments at Băcăinți - OSPA Alba and Turda - SCDA, with subsequent proposals for protection and increase of soil fertility and environmental conditions. In the same context, certain interpretations and limits are promoted in the foundation of agrochemical measures for fertility modelling and increased effect of fertilizers.
