این تحقیق با هدف ارزش گذاری اقتصادی عناصر غذایی اصلی خاک و با تأکید بر خاک جنگل های منتخب منطقه حفاظت شده شیمبار در استان خوزستان انجام شده است. در این پژوهش ابتدا با روش epm، میزان فرسایش تعیین و سپس مقدار هدر رفت سه عنصر غذایی مهم (نیتروژن، فسفر و پتاسیم) بر اساس اختلاف مقادیر عناصر غذایی دو تیمار شاهد و فرسایش یافته اندازه گیری شد؛ سپس ارزش پولی نگهداری عناصر غذایی خاک به وسیله پوشش جنگلی، ب...
The recent years' problems of herbicide use have led a growing number of researchers to seek alternative methods that are less reliant on herbicides. This research was conducted to determine the effect of long-term crop rotation, mineral fertilizer and herbicide on the weed infestation and grain yield of winter rye during 2004 and 2005 at the long-term experimental site of the University of Tim...
background and objectives: production and use of fertilizers in common agriculture have been many environmental problems. while the application of organic fertilizers instead of chemical fertilizers have a important role in soil fertility, increase quality of production and safety of agricultural ecosystems. pumkin, is an important annual herbaceous plant belongs to the cucurbitaceae family due...
the exponential growth of urbanization leads to increase in severity of environmental problemsespecially assonated with disposal of solid waste. with considering the increasing rate of solid waste generation in urban area, the problem of availability of space required to dispose it off is become a concern for planners and administrators of urban local bodies (ulb). in order to cope up with the ...
Recently, precision agriculture has become a globally attractive topic. As one of the most important factors, the soil nutrients play an important role in estimating the development of precision agriculture. Detecting the content of nitrogen, phosphorus and potassium (NPK) elements more efficiently is one of the key issues. In this paper, a novel chip-level colorimeter was fabricated to detect ...

The use of chemical fertilizer along with organic is an important agricultural practice that improves crop yield but also affects soil biogeochemical cycles. In this study, a maize field experiment was conducted to investigate the effects NPK (NPK), (OF), and their combination (NPK+OF) on properties, bacterial fungal community structures, diversity compared control (CK, without any fertilizer)....
A field experiment was carried out throughout Zaid season 2022 on the research farm of Department Soil Science and Agricultural Chemistry, SHUATS, Prayagraj, to examine variations in physicochemical properties soil yield maize, as affected by levels NPK vermicompost eastern part Uttar Pradesh. The at test site sandy loam texture is located 25024’30’’ North latitude, 81051’10” East longitude, ab...
