A Dynamic Cone Penetrometer for Measuring Soil Penetration Resistance
ters to characterize both agricultural and rangeland A DYNAMIC CONE PENETROMETER soils, however, has been limited by concerns about (i) FOR MEASURING SOIL instrument cost, (ii) measurement repeatability, (iii) limited ranges of soil resistance that can be measured by PENETRATION RESISTANCE a single penetrometer, and (iv) difficulties in comparing Jeffrey E. Herrick* and Tim L. Jones data collec...
متن کاملDesign of a Horizontal Penetrometer for Measuring On-the-Go Soil Resistance
Soil compaction is one of the main negative factors that limits plant growth and crop yield. Therefore, it is important to determine the soil resistance level and map it for the field to find solutions for the negative effects of the compaction. Nowadays, high powered communication technology and computers help us on this issue within the approach of precision agriculture applications. This stu...
متن کاملSoil Degradation - I: Effect of Fertiliser Use on Penetrometer Resistance
A 58-yearold burning and trashing trial receiving fertiliser and no fertiliser was used to quantify treatment effects on soil penetrometer resistance. The results showedthat penetrometer resistance was significantly lowerin thosetreatments whereno fertiliser wasapplied. Increased soilwatercontentin treatments witha trashcoverdid notreducepenetrometer resistance values in the soil wherefertilise...
متن کاملEffect of microbial activity on penetrometer resistance and elastic modulus of soil at different temperatures
We explore the effect of microbial activity stimulated by root exudates on the penetrometer resistance of soil and its elastic modulus. This is important because it is a measure of the mechanical strength of soil and it correlates closely with the rate of elongation of roots. A sandy soil was incubated with a synthetic root exudate at different temperatures, for different lengths of time and wi...
متن کاملA Statistical Basis for Selecting Parameters for the Evaluation of Soil Penetration Resistance
Measurements of soil penetration resistance (SR) have been frequently used for the evaluation of soil structural quality for plant growth. However, different data analysis approaches have been used, without a previous evaluation of their statistical quality. In this study we tested the hypothesis that the mean is the parameter with best statistical properties to evaluate alterations in soil pen...
