Abstract

Precision tillage (PT) is an innovative method that aims to take mechanical actions in the soil only where it is needed to curb the impact of heavy machinery usage on the soil. This research explores the use of remote sensing to measure relevant soil parameters to implement a PT strategy. This was achieved by combining traditional soil properties measurements and a non-contact approach based on taking hyperspectral camera (HSC) data in the field. Six methods were generated and divided into two sets to determine soil properties to make PT decisions. The first set includes mathematical functions that were generated from the ground true data (GTD). The second set includes functions that were generated from the remotely sensed HSC data and have a relationship with the methods in the first set. It was possible to tune the functions’ parameters to increase the accuracy. In addition, prediction error categories set at 5 % intervals were used to select the best method. The results show that a tuned method based on the GTD has an overall error below 5 %, and a tuned method based on HSC data has an overall error below 10 %.

遥感技术在测量精准耕作土壤参数方面的评估

精确耕作（PT）是一种创新方法，旨在只在需要的地方对土壤采取机械措施，以抑制重型机械使用对土壤的影响。这项研究探讨了如何利用遥感技术测量相关土壤参数，以实施精准耕作战略。通过结合传统的土壤特性测量方法和基于在田间获取高光谱相机（HSC）数据的非接触式方法，实现了这一目标。共产生了六种方法，并将其分为两套，用于确定土壤特性，以做出 PT 决策。第一套包括从地面真实数据（GTD）中生成的数学函数。第二组包括根据遥感 HSC 数据生成的函数，这些函数与第一组中的方法有关联。可以通过调整函数参数来提高精度。此外，还采用了间隔为 5% 的预测误差类别来选择最佳方法。结果显示，基于 GTD 的调整方法的总体误差低于 5%，而基于 HSC 数据的调整方法的总体误差低于 10%。
