Soil Physical Properties and Production of Upland Ultisol Soil [PDF]

, 2012
Acid upland soil in Indonesia has a great potential for agricultural development but the soil physical properties have been degraded. The use of manure and direct application of Gresik phosphate rock (PR) was an alternative to improve land productivity ...

Physical Properties of a Hapludox after Three Decades under Different Soil Management Systems

Revista Brasileira de Ciência do Solo, 2016
Changes in soil physical properties due to different management systems occur slowly, and long-term studies are needed to assess soil quality. The objectives of this study were to evaluate the effects of soil management systems and liming methods on the ...

Cropping sequence influenced crop yield, soil water, and soil properties in wheat-camelina cropping system

Farming System
Integrating camelina (Camelina sativa L. Crantz) into wheat (Triticum aestivum L.) -based cropping systems in the Great Plains Region of the United States could improve soil properties and overall system productivity. However, there is little information

Variations in chemical and physical properties of Amazon forest soils in relation to their genesis [PDF]

Biogeosciences, 2010
Soil samples were collected in six South American countries in a total of 71 different 1 ha forest plots across the Amazon Basin as part of the RAINFOR project. They were analysed for total and exchangeable cations, C, N, pH with various P fractions also

Microflora in soils of desert regions [PDF]

, 1970
Desert soil samples, collected using aseptic techniques, are low in organic matter and cation exchange capacity. Aerobic and microaerophilic bacteria are most abundant, next are algae and molds. Chemical and physical properties are determined by standard

Soil Properties and their Influence on Grassland Production under Low Input and Organic Farming Conditions [PDF]

, 2006
End of project reportThis project set out to identify soil properties that most influence grassland production under low mineral nitrogen input conditions. Sixteen farms were selected in Counties Limerick and Clare and the soil sampled. Soil physical and
