Agricultural science (or agriscience for short [1] ) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists.
In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulfate) as a fertilizer. [2]
In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. [3] [4] [5]
In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term "agricultural science". [6] [7] The Hatch Act was driven by farmers' interest in knowing the constituents of early artificial fertilizer. The Smith–Hughes Act of 1917 shifted agricultural education back to its vocational roots, but the scientific foundation had been built. [8] For the next 44 years after 1906, federal expenditures on agricultural research in the United States outpaced private expenditures. [9] : xxi
Climate change has had significant effects on modern agriculture, making weather patterns less predictable and increasing the frequency and intensity of extreme events such as prolonged droughts, floods and heatwaves. As a result, crop production has become more uncertain even in regions that were previously characterised by relatively stable climatic conditions. [10] Changes in temperature and rainfall regimes are also contributing to soil erosion, desertification and the degradation of water resources, with implications for long-term agricultural productivity and rural livelihoods. [11]
To address these issues, there has been increasing interest in agricultural research and practice in the so-called climate-smart strategies aimed at adapting agricultural systems to the existing and the forecasted climate effects and the minimisation of greenhouse gas emissions wherever feasible. These measures involve more efficient use of water and nutrients, crop and agriculture system diversification, soil and water protection, and creating crops and livestock strains more resistant to heat and drought among other challenges. The thrust of these endeavors defines the fundamental importance of agricultural science to the maintenance of food production, safeguarding natural resources and promoting resilience to environmental change.

Agriculture, agricultural science, and agronomy are closely related. However, they cover different concepts:
