In the country, livestock is firmly integrated into the economic structure of farm and village life. Livestock raising is being recognized as a key element which contributes to rural income and to the efficient use of the available resources in the rural sector. The raising of farm animals is still on a small scale basis since it is intimately tied-in with farmers' activities and way of life. C...
Organic farming follows the principle of circular causation and has emerged in response to questions on health, environment and sustainability issues. In this review, we assess the status, opportunities and Csequestration potentials of OF in India. We identify constraints that impede adoption of OF especially for small farm holders who constitute over 70% of farming community in India. With lar...
the main purpose of this study was to analyze the problems of water user associations (wuas) in the irrigation management transfer (imt) process. the study is based upon a descriptive-correlational research method. the statistical population of the study consisted of 2500 farmers in wuas. a sample of 262 farmers was selected using “random sampling” method. data were collected through questionna...
According to importance of forests, enforcement of accurate and systematic management about them is necessary; in this regard recognition of soil quality is essential principles. With the aim of studying soil macroelement in each of Populus deltoiedes, Alnus subcordata, Taxodiom distichum stands and around uncultivated area (control), 8 samples taken from each of 0-15cm and 15-30cm depth. Soil ...
This study covers a large agricultural and industrial area of Isfahan province, including three types of land use, i.e., agricultural, uncultivated, industrial and urban types. A total of 275 samples from surface soil (0-20 cm) were collected and water soluble fluoride concentrations of them were measured. The spatial structure of water soluble fluoride in the soils was determined by omnidirect...
The aim of this work, to estimate the External exposure, ingestion Exposure and inhalation exposure dose rate from gamma ray released from Natural Radionuclides in cultivated, uncultivated and phosphate soil samples in the area surrounding EL-Naser Factory for phosphate in El-Mahamid, Idfu, Aswan, Upper Egyp by using modeling, this model studied the exposure gamma radiation from different natur...
Spatial Variation of Soil Organic Carbon and Total Nitrogen in the Coastal Area of Mid-Eastern China
Soils play an important role in sequestrating atmospheric CO₂. Coastal tidal flats have been intensively reclaimed for food security and living spaces worldwide. We aimed to identify the changes of soil organic carbon (SOC) and total nitrogen (TN) following coastal reclamation and their spatial variation in the coastal area of mid-Eastern China to provide information for coastal cropland manage...
this research was conducted to study the effect of land use change on some physical fractionation component of organic matter and some of its quality factors. therefore, two uncultivated and cultivated (such as rotational cropping and sugarcane) were selected in khuzestan province. disturbed and undisturbed soils were sampled from 0-30 and 30-60 cm depths. total n, oc, dispersible clay (dc), ag...
Excessive water is used by farm field in Tarim river basin, it is very important to deep study on the relation between area of farm field and natural vegetation in recent 50 years. Collecting and processing various decades of remote sensing data, and got area of farm field, grass, forest, town and non-serviceable field. These results indict that: Because of the high flow period between 1950 and...
