Abstract

ABSTRACT Soil penetration resistance (SPR) is used as an indicator of compaction, as it is related to important soil and plant attributes and is an easily obtainable measure. Its determination with the use of the penetrometer guides to the best soil management strategies, thus favoring crop development. The objective of this study was to develop and validate the georeferenced hydraulic driven electronic penetrometer, making it easier to obtain SPR. For this, 36 SPR readings from 0 to 0.60 m depth were performed with the manual and hydraulic penetrometers in two areas. The SPR results were analyzed by establishing the confidence intervals by the t-test (p ≤ 0.10) at each 0.05 m depth and the georeferencing was analyzed through the root mean square error (RMSE). It was found that both penetrometers showed similarity in SPR measurement and in the georeferencing of the points.

用于地理参考点采集的液压驱动电子穿透仪的研制与验证

土壤渗透阻力(Soil penetration resistance, SPR)与土壤和植物的重要属性有关，是一种容易获得的测量方法，被用作土壤压实度的指标。它的测定与使用贯入仪指导最佳土壤管理战略，从而有利于作物的发展。本研究的目的是开发和验证地理参考液压驱动电子贯入仪，使其更容易获得SPR。为此，在两个区域使用手动和液压贯入仪进行了36次SPR读数，深度从0到0.60 m不等。SPR结果在每0.05 m深度采用t检验(p≤0.10)建立置信区间进行分析，地理参考采用均方根误差(RMSE)进行分析。结果表明，两种贯入仪在SPR测量和点的地理参考上具有相似性。
