Properties Of Soil

Physical properties of soil are good for plant growth is closely related to the management of the soil, so it will need to integrate of physical properties to get an overall assessment with making soil physical quality index (SPQI). This study aims to an evaluation of physical properties and determines the physical quality index using several unit treatments to produce various physical qualities on Groundnut/Arachis hypogeal L. The location of the research was carried out in a farmer's garden in Cimaung Village, Cikeusal District, Serang Regency, Banten Province (Coordinates 6o12’14’’ S dan 106o11’52’’E). To analyze the SPQI using several physical properties of the soil such as texture, bulk density, porosity, permeability, and aggregate stability. Each indicator has a scoring parameter to assess the soil physical quality index with a score range of 0-5. An assessment SPQI in a land unit is able to describe the various physical qualities of the soil which are represented by several physical properties of the soil. The unit treatment which class categorization of soil physical quality index indicated slightly good (U2), medium (U1, U3-U6), and slightly poor (U7) as a control.

Significant Difference

Sokoto Rima Flood Plain (SRFP) is located in Sudan Savanna agro-ecology of Nigeria, and is faced with the common challenge of flooding towards the end of the rainy season and widespread drought with high potential for irrigated rice production during dry season. Two year experiment was conducted in the dry season of 2018 and 2019 in a farmer`s field, near the Usmanu Danfodiyo University Teaching and Research Farm, Kwalkwalawa in SRFP, Sokoto State. The treatments consisted of factorial combination of two tillage practices; conventional and reduced tillage, three irrigation schedules; one, two and three days schedule of irrigation and three rice varieties (FARO 44, 60 and 61). Treatments were laid in a split plot design replicated three times, where tillage practices and irrigation schedules were allocated to the main plots while rice varieties to the sub-plots. Data on particle size distribution, bulk density and water retention were simulated by RETC model for Mualem-van Genuchten parameters and for estimating the soil physical quality index (S) and the grain yield (kgh-1) of rice varieties were extrapolated from the net plots. Statistical analysis software was used to analyze all data generated, where significant means were compared using Duncan Multiple Range Test. The results revealed that RETC output for van Genutchen parameters demonstrated significant difference between the two tillage practices, irrigation schedule and depth on the value of curve fitting parameters (n). Soil physical quality index (S) increased with increase in soil depth, although not statistically different. From the finding, the S-index in the study area was in the range of 0.023-0.025, which by grouping was considered moderately suitable for optimal root growth. Also, FARO 44 performed better than other varieties in both 2018 (540.05 kgh-1) and 2019 (5835.85 kgh-1), respectively with one day irrigation schedule and convectional tillage practice. Forage legume incorporation during rainy season should be encouraged to improve the soil physical quality over time.

Definition Of

The algorithm has been developed and creation of the register for standard physical parameters of the mane arable soils has been started on the basis of a multipurpose database of relational type “Ukrainian soil properties”. Soils are positioned in space of provinces of nature-agricultural zoning of Ukraine. The purpose of work is an estimation of soil physical quality. Calculations of the integrated index of soil physical quality are carried out according to the way developed by authors. The method is based on definition of soil physical quality on 7 basic physical properties. Nature-agricultural zoning is a spatial basis, and a province – the smallest spatial unit. Soil physical quality for different types has been compared in borders of each province by relative criteria. Key words: soil physical quality index; standard; nature-agricultural zoning; province.

The Impact

The multi-height (low, L = 3 cm; intermediate, M = 100 cm; high, H = 200 cm) Beerkan run methodology was applied on both a minimum tilled (MT) (i.e., up to a depth of 30 cm) and a no-tilled (NT) bare loam soil, and the soil water retention curve was estimated by the BEST-steady algorithm. Three indicators of soil physical quality (SPQ), i.e., macroporosity (Pmac), air capacity (AC) and relative field capacity (RFC) were calculated to assess the impact of water pouring height under alternative soil management practices. Results showed that, compared to the reference low run, M and H runs affected both the estimated soil water retention curves and derived SPQ indicators. Generally, M–H runs significantly reduced the mean values of Pmac and AC and increased RFC for both MT and NT soil management practices. According to the guidelines for assessment of SPQ, the M and H runs: (i) worsened Pmac classification of both MT and NT soils; (ii) did not worsen AC classification, regardless of soil management parameters; (iii) worsened RFC classification of only NT soil, as a consequence of insufficient soil aeration. For both soil management techniques, a strong negative correlation was found between the Pmac and AC values and the gravitational potential energy, Ep, of the water used for the infiltration runs. A positive correlation was detected between RFC and Ep. The relationships were plausible from a soil physics point of view. NT soil has proven to be more resilient than MT. This study contributes toward testing simple and robust methods capable of quantifying soil degradation effects, due to intense rainfall events, under different soil management practices in the Mediterranean environment.
