In multimedia mass-balance models, the soil compartment is an important sink as well as a conduit for transfers to vegetation and shallow groundwater. Here a novel approach for constructing soil transport algorithms for multimedia fate models is developed and evaluated. The resulting algorithms account for diffusion in gas and liquid components; advection in gas, liquid, or solid phases; and mu...

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...

The electromagnetic spectrum extends from Hertz to terahertz. In this large range of EM spectrum there are window defining the smaller ranges and one of the important windows which covers frequency range from 3GHz to 30GHz is known as Microwaves. These Microwaves have various applications in communication Industrial, Medical and Remote Sensing. The Microwaves have unique Properties that include...

Subsoiling to a depth of 35 cm under the planting row for 3 consecutive years increased annual yields of seed cotton by 50 to 200%. Annual subsoiling was essential for maximum yields. The application of a nematicide, 1,2-dibromo-3-chloropropane (DBCP) or aldicarb, reduced the population of Hoplolaimus columbus but did not increase seed-cotton yields over subsoiling alone. Subsoiling reduced H. ...

Fipronil (Termidor 80 WG) was applied to covered and exposed plots at one secondary and four primary USDA Forest Service termiticide test sites in the U.S. Residue analyses and bioassays of soil samples were conducted over 5 y. Fipronil had an exponential decay at all sites. The DT 50 of fipronil in a silt loam soil in Oktibbeha Co., MS in covered and exposed plots was 202 and 177 d, respective...

ABSTRACT: Although the piezocone penetration test (PCPT) has several advantages over traditional methods of sampling and laboratory analysis in determining representative properties of a soil deposit, the existing methods used to infer soil properties from PCPT data are not always reliable due to the complexity of cone penetration. In this study, it is proposed that the process of “data fusion”...

Soils are three-dimensional (3D) natural bodies conSlStmg of unconsolidated mineral and organic materials that form a continuous blanket over most of the earth's land sUlface. At all scales of measurements, soils are exceedingly complex and variable in bio logical, chemical, physical, mineralogical, and electromagnetic properties. These properties influence the propaga tion velocity, attenuatio...

Abstract Soil compaction and degradation due to improper tillage are problems involving significant natural economic damages. On compacted soils, suitable cultivation can be implemented only with higher energy traction force input. In our study, the effect of a soil conditioner (Neosol) was examined on penetration resistance power demand for ploughing in experiment set up East-Slovak Plain 2017...

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...
