Abstract

Способ почвенно-агрохимического обследования сельскохозяйственных угодий, включающий сбор предварительной информации о состоянии объекта, отбор смешанных проб и их химический анализ, отличающийся тем, что составляют проект работ по агрохимическому обследованию на основе полученной геоморфологической информации обследуемых участков сельскохозяйственного угодья в полевых условиях, включающий карту маршрутов отбора почвенных проб, в котором определяют расстояние между соседними маршрутами, намечают координаты начала и окончания отрезка, с которого производят отбор смешанной пробы, выносят составленный проект работ по агрохимическому обследованию в натуру, при этом производят корректировку длины отрезков по ходу маршрутов отбора почвенных проб, с которых отбираются почвенные смешанные пробы с учетом фактических геоморфологических условий обследуемого сельскохозяйственного угодья, отбирают смешанные почвенные пробы при сплошном обследовании, отбирают контрольные смешанные почвенные пробы по контрольному маршруту в произвольном направлении с различной длиной отрезка с учетом геоморфологических условий, а для определения степени достоверности выделенных пространственных границ контуров на полученную карту наносят по координатам «центры тяжести» с контрольных маршрутов, их сопряженные атрибутивные данные, проводят их интерполяцию и получают значения точек, характеризующие место прохождения границ почвенно-агрохимических контуров, измеряют расстояния между местом прохождения границ, выделенного при сплошном обследовании и значениями показателей границ контрольного маршрута для получ�A method of soil-agrochemical inspection of agricultural land, including the collection of preliminary information about the condition of the object, the selection of mixed samples and their chemical analysis, characterized in that they compile a project for work on agrochemical inspection based on the obtained geomorphological information of the examined plots of agricultural land in the field, including a map of routes soil sampling, in which the distance between adjacent routes is determined, the coordinates of the beginning and end of the cutting from which the mixed sample is taken, the prepared draft work on agrochemical examination is carried out in kind, while the lengths of the sections along the soil sampling routes are adjusted, from which the mixed soil samples are taken taking into account the actual geomorphological conditions of the agricultural land being examined, mixed soil is taken samples during a continuous examination, control mixed soil samples are taken along the control route in an arbitrary direction with different lengths th segment, taking into account geomorphological conditions, and to determine the degree of certainty of the selected spatial boundaries of the contours, the “centers of gravity” from the control routes are applied to the resulting map according to the coordinates, their associated attribute data are interpolated and the values of the points characterizing the location of the boundaries of the soil-agrochemical contours, measure the distance between the border crossing point, selected during a continuous examination and the values of the boundaries of the control route to obtain
