Thermodynamic state functions of the soil water system. Farming systems are defined by the patterns in time and space in which producers grow their crops; the management decisions regarding the inputs and production practices used; the management skills, education, and objectives of the producer; the quality of the soil and water; and the nature of the landscapes and ecosystems within which production takes place. The formalism of generalized thermodynamics is applied to moist soil, as a three phase system, to derive expressions for the thermodynamic functions of each phase in terms of well defined characteristic variables. Gravimetric soil water content is the mass of water in the soil, measured as the difference between the moist soil and the soil dried at 105°C, known as the oven-dry weight. We tend to take the soil around us for granted. The drainage system designed to evacuate salty water also lowers the water table. STEP Systems develops, manufactures and distributes portable analytical systems and tools, particularly designed for testing and monitoring of soil, water and air (climate). More then 20 years of collaboration between European soil scientists has resulted in the publication by the European Commission of the first ever "Soil Atlas of Europe". As such, soil health and soil tilth improve as tillage becomes less intensive. Soil water content can be measured on a mass or volume basis.
Special Issues. Plants grow and depend on the soil. Soil salinity control relates to controlling the problem of soil salinity and reclaiming salinized agricultural land. topic 5.1: Introduction to Soil Systems Image from Food Tank.
All the food that we consume depends ultimately upon soil. Interdisciplinary manuscripts are particularly welcome, as the soil-sediment-water system lies at the basis of all societal challenges of our time. By learning more about the soil system and water management, producers can improve productivity and profitability by building a better soil system. Soil water content affects the moisture and amount of nutrients available to plants and soil aeration status. Mother Nature never tilled the soils and a diverse soil system developed, yet man feels that tillage is necessary.
We either eat plants that grow directly in the soil or the animals that eat the plants.

The Department of Soil and Water Systems combines faculty in soil science, agronomy, hydrology, sediment transport, irrigation engineering, waste management and precision agriculture to address resource issues related to soil, water quality and quantity and sustainable food, energy and waste systems.
