Agronomy Journal, Volume 113, Issue 6, Page 4541-4559, November/December 2021., 2021 Abstract A growing world population and increases in food and energy consumption have placed production agriculture in a difficult situation. The rapid growth in food production through specialized operations such as monoculture cropping systems has aligned to satisfy increases in demand for food and fiber.

An integrated spatial econometric approach in valuing soil conservation using contingent valuation
Soil Use and Management, Volume 37, Issue 2, Page 377-389, April 2021., 2021 Abstract The integration of soil value in agronomic micro‐level decision‐making and macro‐scale policy development has grown immensely in recent years. Major threats to soil resources and their impact on human well‐being require a comprehensive estimation of soil's economic worth, highlighting the need for sustainable and pragmatic conservation ...

How to compare sampling designs for mapping?
European Journal of Soil Science, Volume 72, Issue 1, Page 35-46, January 2021., 2021 Abstract If a map is constructed through prediction with a statistical or non‐statistical model, the sampling design used for selecting the sample on which the model is fitted plays a key role in the final map accuracy. Several sampling designs are available for selecting these calibration samples. Commonly, sampling designs for mapping are compared in

Perspectives on validation in digital soil mapping of continuous attributes—A review
Soil Use and Management, Volume 37, Issue 1, Page 7-21, January 2021., 2021 Abstract We performed a systematic mapping of validation methods used in digital soil mapping (DSM), in order to gain an overview of current practices and make recommendations for future publications on DSM studies. A systematic search and screening procedure, largely following the RepOrting standards for Systematic Evidence Syntheses (ROSES) protocol,
