Comparing the models’ predictions to the measured results of experiments and long term observations offers a way to test the understanding that they represent and probe for weaknesses. The long-term data sets maintained by LTER sites are also an invaluable resource for calibrating and testing ecological models developed by other researchers. RYCHLIK, B - ADAMIAK, J. - WOJCIAK, H.

Principles and Standards for Measuring Net Primary Production in Long-Term Ecological Studies is the first book to establish a standardized method for measuring net primary productivity (NPP) in ecological research. Primary productivity is the rate at which energy is stored in the organic matter of plants per unit area of the earth’s surface. Effects of Conventional and Organic Agricultural Techniques on Soil Ecology soil organisms and argues for an increase in the use of organic agriculture strategies to maintain healthy soil in the long term. The paper focuses on the relationship between soil ecosystems and the following: tilling, pesticides, biodiversity, fertilizers.

Barry Glaz retired as a Research Agronomist of the USDA-ARS Sugarcane Field Station in Canal Point, Florida. His major research interests were 1) to identify the agronomic limits of and improve the tolerance of sugarcane to periodic water levels at or near the soil surface, and 2) to contribute to the development of high-yielding, disease resistant/tolerant sugarcane cultivars.
Long-Term Experiments. Data from long-term experiments are a prerequisite for reliable conclusions about the effects of OA practices on SOC stocks, and some results will be discussed later in the chapter.
For example, mean SOC stock changes in Ap horizons at long-term experiments in Germany and Switzerland were highly variable (Brock et. Statistics and the long-term experiments: past achievements and future challenges. in: Johnston, A. and Leigh, R. (ed.)

Cited by: A long-term experiment is an experimental procedure that runs through a long period of time, in order to test a hypothesis or observe a phenomenon that takes place at an extremely slow rate. Several agricultural field experiments have run for more than years, but much shorter experiments may qualify as "long-term" in other disciplines.
An experiment is "a set of actions and observations.

Long-term data reveals how no-till agriculture increases crop yields and environmental gains over the long haul Despite the environmental benefits of no-till agriculture, farmers often hesitate to change to this management approach due to uncertain economic returns.
From its start in with six projects, the Long Term Ecological Research (LTER) program has now grown to 24 projects involving more than scientists.
This article describes why the program exists and what it does. But the success of a scientific program cannot be measured by the number of sites or scientists involved in a project.Agriculture, agricultural science, and agronomy. The three terms are often confused.
However, they cover different concepts: Agriculture is the set of activities that transform the environment for the production of animals and plants for human use.
Agriculture concerns techniques, including the application of agronomic research.
