is a numerical model for simulating the 1-dimensional flux of soil heat, soil water  and carbon in agricultural systems.

is internationally recognised as a highly advanced simulator of agricultural systems. It contains a suite of modules which enable the simulation of systems that cover a range of plant, animal, soil, climate and management interactions.


is the FAO crop-model to simulate yield response to water of several herbaceous crops.

is a general model of plant-soil nutrient cycling which is being used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, forests and savannas.

is a process-oriented, dynamic model which describes water-heat-carbon (C) and nitrogen (N) flows in the soil-plant-atmosphere system as a function of climate at various time and spatial scales ; typically from minute to day and from field to regional scales (Jansson, 2012; Jansson & Karlberg, 2004). The model is driven by standard meteorological data (i.e. precipitation, temperature, wind-speed, global radiation and air humidity) and can simulate plant growth and N-uptake, soil water, C and N dynamics and the resulting nitrate leaching at high temporal resolution. The dynamic growth-module is especially suitable for exploring the potential changes in yields and N-leaching linked to different climate, soil and management (including input of fertilizer or crop residues).

is a user-friendly, conceptually simple but sound multi-year multi-crop daily time step simulation model.

is a daily time series biogeochemical model used in agroecosystems to simulates fluxes of carbon and nitrogen between the atmosphere, vegetation, and soil.

is a software application program that comprises crop simulation models for over 28 crops (as of v4.5).

is a cropping systems model that was developed to estimate soil productivity as affected by erosion as part of the Soil and Water Resources Conservation Act analysis for 1980

is a development system with the aim to improve the process understanding of the turnover and transport of matter and the energy fluxes in the soil-plant-atmosphere system. The focus are the simulations of matter cycling in forest, grassland, and crop ecosystems from the field to the regional scale.

is a model to describe plant growth and water and nitrogen dynamics in the soil-plant system.

is a new model system, which facilitates scaling of ecosystem processes from the site to regional simulation domains.

is a crop growth model that is able to simulate crop growth model under both potential and water limited (i.e. rainfed) conditions.

is a process-based general crop model.

is a is a dynamic, process-based simulation model which describes the transport and bio-chemical turn-over of carbon, nitrogen and water in agro-ecosystems.

is a model for the turnover of organic carbon in non-waterlogged topsoil that allows for the effects of soil type, temperature, soil moisture and plant cover on the turnover process.

is designed to model continuous crop, soil, water and nutrient conditions under different management strategies for multiple years.

is a modular modelling framework to support decisions for the management of a wide range of crops and ecosystems under changing resource availability and climate conditions. The framework is  developed with standard technologies, which reduce the effort in model development and customization. It includes the flexibility necessary to be customized, used and extended by scientists. The multi-threaded high performance architecture enables calibration and simulations at different spatial scales.

is an interdisciplinary simulator for standard crops, models crop development at plot level across all agronomic criteria: climate, soil, and agricultural practices. It is also able to model intercropping systems and crop rotation cycles.
