Water-related physical attributes of organic soils

2002
Conservation of organic soils used for agriculture requires proper regulation and partitioning of water flow in the environment. This chapter reviews the physical properties involved in water retention and transfer in drained organic soils. Basic physical properties are bulk density, specific density, porosity, and ash content.

Chapter 2 Physical attributes of soil quality

1997
Publisher Summary Crop production and ecosystem health are affected strongly by soil physical quality, particularly in the root zone. The soil must provide a foundation that is sufficiently strong to provide adequate plant support and stable soil structure but not so strong as to inhibit root proliferation and faunal activity, such as burrowing ...

Geospatial variation of physical attributes and sugarcane productivity in cohesive soils

Precision Agriculture, 2019
Sugarcane productivity is highly variable across space, and knowledge about the spatial distribution of soil physical attributes is important to guide management practices and evaluate the effects of agricultural operations on productivity. Thus, the objective of this study was to determine the best sampling density to represent the physical attributes

Soil Management in the Physical Attributes and the Wheat Crop Irrigated Productivity

Journal of Experimental Agriculture International, 2019
The objective of this work was the influence of three management systems on the physical attributes and productivity of irrigated wheat, cultivar BRS-254, in the city of Tangará da Serra, MT, Brazil. The experimental design was a randomized block design in split plots, with eight replications, being considered as plots the three systems of soil ...

Spatial variability analysis and mapping of soil physical and chemical attributes in a salt-affected soil

Arabian Journal of Geosciences, 2019
Knowledge of inherent spatial variability of soil physical and chemical properties is needed for more accurate site-specific management of soil nutrients. In this study we investigated the spatial variability of a wide range of soil physical and chemical properties including soil texture fractions (percentages of sand, silt, and clay denoted as Sand ...

Effects of surface‐applied and soil‐incorporated lime on some physical attributes of a Dystrudept soil

Soil Use and Management, 2017
Abstract It is generally accepted that liming ameliorates soil acidity. However, the method of lime application is thought by many to influence its effectiveness in acid soils. In this study, we wanted to assess the degree of effectiveness of surface‐applied lime and lime incorporated into the soil on soil ...

Soil Chemical and Physical Attributes in Recovering Areas in the Southern Amazon

International Internal Medicine Journal
The recovery of soil quality and forest regeneration is of fundamental environmental importance, especially in the Amazon biome. The objective was to evaluate the contribution of soil’s physical and chemical attributes in degraded areas in recovery process with different ages and compared to adjacent degraded areas cultivated with grassland, in the ...
