Soil quality is an evolving concept intended to aid farmers, land managers, researchers, public decisionmakers, and others in the management of soil resources. The central question of soil quality assessment is “how does a soil function?” and a variety of physical, chemical, and biological indicators can be used to address it. This question, however, is complicated by the interdependencies betw...

The present article is dedicated to the generalization of data obtained in the framework of the preparation of Armenian portion of European Soil Database. Briefly described geography of Armenia. Great variability of soil variants represented in Armenia is recorded. It is shown that nearly all zonal soil types those are developed not only in the region of Little Caucasus and the Armenian Volcani...

Rotavirus is a leading cause of gastrointestinal illness worldwide. Rotavirus transmission occurs fecal-orally, and becomes a critical water quality issue when soil and water resources are contaminated with feces. Transport of pathogens to surface water sources depends on their survival in the soil, especially considering the fact that large amounts of fecal material are often applied to agricu...

Aims: Many experiments have shown a positive effect of species richness on productivity in grassland plant communities. However, it is poorly understood how environmental conditions affect this relationship. We aimed to test whether deep soil and limiting nutrient conditions increase the complementarity effect (CE) of species richness due to enhanced potential for resource partitioning. Methods...

Soil and vegetation are two critical factors for controlling the overland transport kinetics of pathogens in a natural environment. With livestock operations moving more towards concentrated animal operations, the need to dispose of a very large amount of manure in a localized area is becoming increasingly important. Animal manure contains a substantial amount of microbial pathogens, including ...

Soil productivity effects nutritive quality of food plants, growth of humans and animals, and reproductive health of domestic animals. Game-range surveys sometimes poorly explained variations in wildlife populations, but classification of survey data by major soil types improved effectiveness. Our study evaluates possible health effects of lower condition and reproductive rates for wild populat...

Public forests in central Leyte, Philippines provide an important source of annual food crops, perennial cash crops, and rattan and timber to lowland farmers. Household economic dependence upon and uses made of forest resources are associated with relative access to lowland-based activities, especially production of irrigated rice. Households unable to procure sufficient food staples through on...

The nation’s strength, be it social, economic or political depends mostly on the available resources and their proper utilisation. But what is a resource? In simpler terms, resource is the matter or substance which satisfies human wants at a given time and space. Before any element can be designated as resource three basic pre-conditions must be satisfied. They are the knowledge, technical skil...
