Large-scale adoption of alternative agricultural practices is needed to manage farm productivity and resources under global changes. Ecosystem models are a tool for developing and evaluating potential solutions at management and policy scales. However, data collection and compilation often lack documentation that hinders model calibration and testing. The objectives of this study were to describe the current soil datasets and to combine soil property data from various sources that are sufficient to support the use of agricultural models under Korean conditions. Numerous sources provide soil data that describe the farm environment by land cover, such as rice and other field crops. The interquartile range of soil organic carbon was 9.10–14.50 g kg-1 across paddy and non-rice field systems. The results suggest that it is premature to perform site-specific simulations of farming systems due to no direct carbon accounting and hydrological conditions of the soil. Global gridded soil information, such as SoilGrids, may supplement the local data, especially soil organic carbon (the interquartile range of 23.43–36.92 g kg-1). However, the descriptive statistics of soil properties extracted from the datasets were not in agreement. Because the Korean agricultural land is characterized by small size (less than 1 ha) and family operation as a management unit, it is crucial to build datasets more representative of small-size farms and relevant to the new generation of models.

The characteristcs of children`s motor performance are slow response, low accuracy, greater var iability, inappropriate response, and ignoring KR when they perform at will. Not only physical growth, development, and maturation but also information processing capacity results in children`s motor performance deficits. In the late 1970s, motor development theorists accepted information processing model to explain the motor performance differences between adults and children. they try to clarify that whether the performance differences are due to structure(capacity) or function (control process) . To date, many researches show that the performance differnces result from children`s lack of control process rather than children`s small capacity. Children do not know how to lable the incoming information, how to rehearse to memorize the information in the long-term store, and how to organize the information already existed in their memory effectively, However, if children have enough information about specific task, they spontaneously develop adult-like memory strategy. This facts are due to their great knowledge base. Therefore, even though their sophisticated memory strategy can not compensate all their motor deficits, the role of teachers and coaches is to give children various movement experiences making their knowledge base bigger.
