The relevance of the subject under study is to increase yield dry biomass giant miscanthus plants by using fungi and bacteria in its cultivation technology. purpose this was determine effect mycorrhization root system crop symbiosis with on growth development formation their productivity. Field studies were conducted at Veselopodilska Experimental Breeding Station Institute Bioenergy Crops Suga...
Soil surface roughness (SSR) is an important parameter affecting hydrology, erosion, gas exchange and other processes. The of the farmland environment directly related to tillage process. In order accurately characterize random (RR) parameters after ditching, a three-dimensional (3D) digital model was obtained by laser scanning under conditions indoor ditching test, influence oriented component...
This article highlights information on the development of new techniques for preparing planting area nurseries growing seedlings ornamental trees and rare flowers. In forestry, use modern energy-saving agricultural machinery to create optimal conditions plant growth allows high volumes product with minimal labor material costs. Agricultural machines used today do not fully meet agrotechnical re...

Do they report to you, “Here we are?” 36Who endowed the heart with wisdom or gave ...
The suspension velocity is the core of cleaning and sorting mechanisms that utilize a combination fan vibrating sieve. To investigate this, various experimental subjects, such as peanuts with different kernels clay-heavy clods in states, were used. experiment involved simulating materials through numerical calculations using fluid dynamics particle discrete element coupling. Eularian model was ...
Mountains, ocean currents, forests, and swamps have played an important role in regulating global climate for hundreds of millions of years, but the truly novel event of the Cenozoic was the evolution and expansion of grasslands, with their uniquely coevolved grasses and grazers. Neogene expansion of the climatic and geographic range of grasslands at the expense of woodlands is now revealed by ...
حوضه آبخیز سدمخزنی شهید پارسا در جنوب شرقی شهرستان فردوس استان خراسان واق گردیده است . بااحداث این سد علاوه برآبیاری اراضی موجود، 700 هکتار از اراضی جدید پایین دست به زیر کشت می روند. عمده ترین معضل موجود در رابطه با حوضه آبخیز، وجود بار رسوب فراوان و تجمع آن در پشت مخزن سد می باشد. لذابه علت عدم وجود اطلاعات کافی از وضعیت فرسایش خاک در حوضه آبخیز، دراین رساله بررسی و مطالعه فرسایش پذیری خاک ان...
