long term use of fallow in wheat-based cropping system of dry and semi-dry lands can increase erosion and decrease soil fertility. legumes as substituting crops for fallow could improve sustainability in this area. this study was conducted to evaluate the substituting of some legumes for fallow in a 2-yr wheat rotation at research stations in north khorasan province (natural resources research ...

Maintaining winter stubble for the conservation of steppe passerines is widely implemented under the regional agrienvironmental program in Spanish dry lands. The adequacy of such measures was assessed in terms of bird density on different soil cover types in central Spain. Highest bird densities were found in ploughed, sown and fallow plots. Stubble plots were poorly used by wintering passerine...

The experiment was conducted at Dobila, Tarash of Shirajgonj in chalanbeel during the Rabi seasons 2018-2019 and 2019-2020 to improve existing cropping pattern, increase intensity, yields economic return through incorporating modern crop varieties improved management practices. treatments were i) Mustard (var. BARISarisha-14)-Boro-Fallow ii) BARI Sarisha-15)- Boro-Fallow iii) Tori-7)-Boro-Fallo...

To improve the efficiency of agricultural lands condition and use monitoring, method for detecting fallow overgrowth with tree shrub vegetation using multi-temporal multispectral satellite images high spatial resolution is proposed. The task localization solved on basis wavelet analysis. This technique allows to operationally automatically detect areas vegetation. proposed methodology was teste...

The conservation of biodiversity within tropical forest regions does not lie only in the maintenance of natural forest areas, but on conservation strategies directed toward agricultural land types within which they are embedded. This study investigated variations in bird assemblages of different functional groups of forest-dependent birds in three agricultural land types, relative to distance f...

The widespread acquisition of land for large-scale/commercial production of biofuel crops in Ghana has raised concerns from civil society organizations, local communities and other parties, regarding the impact of these investments on local livelihoods. This paper assessed the effect of large-scale acquisition of land for production of Jatropha curcas on farmers’ livelihoods in Ghana. The study...

Wind erosion is a significant problem on 20 million ha of Iran, especially in central plains and coastal areas. Winderosion samplers, meteorological equipments and measurement procedure have been developed over the last twocenturies to measure the particles moving across the field in modes of creep, saltation and suspension. In recentresearch as the first technical measurement in Iran, wind ero...
