Interpretive Summary: This book chapter discussed the use of neutron-stimulated gamma rays analysis for in situ determination of elements(carbon, silicon, oxygen, iron, and potassium along with soil moisture) distributed in soil without the requirement of destructive soil sampling. The neutron-stimulated gamma analysis method paired with GPS can be used for acquiring these data over large agricultural fields. Details of the neutron-gamma analysis technique, methodology of field surveying, data processing algorithm, and mapping procedures will be presented in this chapter.

Technical Abstract: Productivity and profitability of modern agricultural practices require exact knowledge of critical soil elemental (primarily carbon) content over large areas (numerous hectares) of soil surface. Traditional chemical analysis is labor extensive and time consuming that require large number of samples to be collected for laboratory processing. The neutron-stimulated gamma analysis method paired with GPS can be used for acquiring these data over agricultural fields. This method is an in situ nondestructive analysis that requires no sample preparation that can performed in a scanning mode. One working day is required to survey an agricultural field of approximately 30 hectares. Based on field survey results of soil elements (carbon, silicon, oxygen, iron, potassium, and soil moisture), a field distribution map can be created for use in modern agricultural practices. Details of the neutron-gamma analysis technique, methodology of field surveying, data processing algorithm, and mapping procedures will be presented in this chapter.
