Knowledge of the spatial dependency of soil properties, sensitive to grazing systems, is important from an ecosystem protection point of view. In the current study, geostatistical methods and fractal concepts have been used in order to characterize the impact of long-term grazing exclusion on the spatial variability of some soil chemical parameters including organic matter, total nitrogen, avai...

The effects of using organic additives and biofertilizers such as vermicompost, panchgavya, beejamruth, jeevamruth, manure on the growth production strawberries were studied. High levels inorganic compound use in agriculture can negatively impact crop sustainability, increase cultivation costs, decrease productivity. Traditional farming practices, like conservation agriculture, are being adopte...

abstract recharge of aquifers by using wastewater, is one of the important and applicable ways for reusing this valuable water resource, especially in arid and semi-arid regions. as the necessity of local practices for finding the proper management strategies and optimum use of recharge systems (conforming to climate, soil, etc.), a preliminary study was carried out. three physical models were ...

The most important constraint limiting crop yield in developing nations worldwide, and especially among resource-poor farmers, is soil infertility. Therefore, maintaining soil quality can reduce the problems of land degradation, decreasing soil fertility and rapidly declining production levels that occur in large parts of the world needing the basic principles of good farming practice. Minerals...

*Corresponding Author E-mail: [email protected] Tel.: +86-022-84861931 Fax: +86-022-84861931 ‘Biofertilizers’ have been defined as alternative substances, to chemical fertilizers, which can stimulate plant growth and increase yield. Plant growth promoting bacteria (PGPB) represent the main component of biofertilizers. We chose seven bacteria with higher nitrogenase activity, from twenty-nine ...
