Abstract Knowledge of the soil water regime in a dynamic equilibrium condition (steady state) emitter–soil–plant system is essential to evaluate adopted irrigation management, aiming maximize use efficiency irrigation. Thus, our objective was determine integrated effect four levels on moisture (θ v ) distribution pattern, mechanical penetration resistance (PR), and sugarcane rooting. Irrigation...

Abstract Soil penetration resistance is an informative indicator to monitor soil compaction, which affects a range of ecological processes in floodplain ecosystems. The aim the investigation was reveal influence vegetation cover on spatial variability soils. study carried out elm oak forest Dnipro River (Dniprovsko-Orilsky Nature Reserve, Ukraine). profile morphology performed accordance with g...

Aim of study: To reduce the sample size in an agricultural area 167.35 hectares, cultivated with soybean, to analyze spatial dependence soil penetration resistance (SPR) outliers. Area Cascavel, Brazil Material and methods: The reduction was made by univariate effective ( ) methodology, assuming that t-Student model represents probability distribution SPR. Main results: radius intensity have in...

In this review, we examine how roots penetrate a structured soil. We first examine the relationship between soil water status and its mechanical strength, as well as the ability of the soil to supply water to the root. We identify these as critical soil factors, because it is primarily in drying soil that mechanical constraints limit root elongation. Water supply to the root is important becaus...

the aim of this research was to investigate performance of two combined plows compared to conventional plow. the experiments were conducted in a loamy soil texture with moisture content of 16-18% in karaj region of iran. combination of moldboard+chisel plow and disk plow+chisel plow were compared with conventional moldboard plow as three treatments. data was statistically analyzed using rcbd in...

The multipurpose field robot platform BoniRob offers a wide range of possible applications to be carried out by attaching different application modules called BoniRob-Apps. The Penetrometer-App can be used to measure penetration resistance, soil temperature and moisture. To be able to automatize the measurement process of soil properties a GNSSbased navigation for BoniRob has been developed wit...

In this paper, remote sensing measurements like apparent electrical conductivity (ECa.) are used to assess soil compaction. In an experiment comparing five tillage treatments and their effect to energy crops soil penetration resistance (SPR) was measured at the same time as ECa. ECa measurements were carried out using EM-38with dipoles at 1m apart and SPR by an electronic penetrometer. The nega...
