Soil erosion is one of the most critical environmental hazards of recent times. A large area suffers from soil erosion, which in turn, reduces productivity. Methods such as the Universal Soil Loss Equation or Revised Universal Soil Loss Equation are widely used for the estimation of soil erosion from catchment areas. The paper deals with the estimation of soil erosion using Universal Soil Loss ...

The abundance and distribution of nematodes in the soil is influenced by biotic and abiotic soil factors. A previous study based on soil samples collected over a large part of KwaZulu-Natal showed that numbers of Pratylenchus, Helicotylenchus and Paratrichodorus were inversely related to pH and positively related to iron levels in the soil. Weaker relationships occurred between both aluminium a...

The aim of our work was to survey and state the representative values and range of the microbial biomass carbon (Cmic) and microbial respiration activities in arable soils of three types (Chernozem, Luvisol, Planosol) and in pasture grassland soil (Cambisol). In arable soils no significant differences between the soil types were found concerning the content of Cmic. Way of soil use significantl...

Newly reclaimed areas cover several patches over different regions of Egypt, which have different specific characteristics related to climate, soils, hydrology, etc... . The mechanical farm, which extends over 10,000 feddans fares from south of Alexandria by 62 Km, could be considered one of the most important reclaimed areas at West of Nubaria affected by degradation due to water logging. The ...

The ecological drivers of soil biodiversity in the Southern Hemisphere remain underexplored. Here, in a continental survey comprising 647 sites, across 58 degrees of latitude between tropical Australia and Antarctica, we evaluated the major ecological patterns in soil biodiversity and relative abundance of ecological clusters within a co-occurrence network of soil bacteria, archaea and eukaryot...

possibility or good guess of soil occurrence in the survey area. An interpolated map using standard interpolation Due to our imperfect knowledge of soil distributions acquired from techniques may represent an optimal guess based on field surveys, spatial uncertainties inevitably arise in mapping soils at unobserved locations. Providing spatial uncertainty information along the dataset and the i...

Proxy information is used to stratify larger areas, and then measurements within each of these strata are agCarbon storage in soils is important to forest ecosystems. Moreover, gregated and multiplied by the area of each stratum forest soils may serve as important C sinks for ameliorating excess (Schimel and Potter, 1995). Soil survey maps and laboraatmospheric CO2. Spatial estimates of soil or...

We used a survey of attendees of an organic farming conference in Minnesota, U.S.A., to determine whether farmers would be more likely to adopt a fall-seeded winter rye cover crop preceding soybeans if doing so could aid in the suppression of soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae). Of the 24 soybean growers that responded to our survey, 22 indicated that they would be mo...
