Soil penetration resistance in a rhodic eutrudox affected by machinery traffic and soil water content

Soil Cohesion as Affected by Time and Water Content

Cohesion increased for several months after disruption in moist soils. Rate at which cohesion increased was slower in airdry soil, but continued for years. Moduli of rupture of soils also increased with time. Effects of water content on the rate at which cohesion increases are compatible with an explanation of the bonding mechanism in terms of slightly soluble components diffusing to and cement...

Soil compactibility as affected by soil moisture content and farmyard manure in central Iran

Soil compactibility which basically depends on soil texture, organic matter and soil water content during farm machinery traf®cking are major factors affecting soil conservation. In a ®eld experiment, cattle farmyard manure was applied to a silty clay loam soil (®ne-loamy, mixed, thermic Typic Haplargids, USDA; Calcaric Cambisols, FAO) in Isfahan, Iran. Three rates, 0, 50, 100 Mg haÿ1 (on oven ...

Microbial degradation of sulfentrazone in a Brazilian rhodic hapludox soil

Sulfentrazone is amongst the most widely used herbicides for treating the main crops in the State of São Paulo, Brazil, but few studies are available on the biotransformation of this compound in Brazilian soils. Soil samples of Rhodic Hapludox soil were supplemented with sulfentrazone (0.7 µg active ingredient (a.i.) g(-1) soil) and maintained at 27°C. The soil moisture content was corrected to...
