On the base of the Integrated Agricultural Administration and Controlling System (InVeKos) the Federal State of Thuringia (Germany) has a strong interest in actual, area covering land use types and borders. Until now the inventory is based on optical orthophotos. Goal of this study is to analyze, whether these orthophotos might be replaced by spaceborne remote sensing data, especially by multit...

This study examines the determinants of farmers’ willingness to pay (WTP) and their payment levels for ecological compensation of the Poyang Lake Wetland in China. We developed a farmer household survey and gathered 292 effective responses. The contingent valuation method (CVM) and Heckman’s two-step model were employed for the empirical study. Results show that 46.58% of farmers are willing to...

BACKGROUND Until recently, a lot of arable lands were abandoned in many countries of the world and, especially, in Russia, where about half a million square kilometers of arable lands were abandoned in 1961-2007. The soils at these fallows undergo a process of natural restoration (or self-restoration) that changes the balance of soil organic matter (SOM) supply and mineralization. RESULTS A s...

We organized a crowdsourcing experiment in the form of a snapshot sampling campaign to assess the spatial distribution of nitrogen solutes, namely, nitrate, ammonium and dissolved organic nitrogen (DON), in German surface waters. In particular, we investigated (i) whether crowdsourcing is a reasonable sampling method in hydrology and (ii) what the effects of population density, soil humus conte...

The experimental data of long-term researches establishing high efficiency of soil-protective system of agriculture with use of bioresources on biological and humus in condition of arable grey forest soil has been presented.

One of the objectives of agricultural development in Botswana is the increase of agricultural productivity in both arable and livestock production in order to increase farm incomes and thus help to make agriculture a sustainable activity. This paper looks at the challenges that Botswana faces in meeting this objective while minimizing any land degradation that may accompany the process of incre...

BACKGROUND Concentrations of the neonicotinoid insecticides clothianidin, thiamethoxam and imidacloprid were determined in arable soils from a variety of locations in England. RESULTS In soil samples taken from the central area of fields, concentrations of clothianidin ranged from 0.02 to 13.6 µg kg(-1) . Thiamethoxam concentrations were between <0.02 and 1.50 µg kg(-1) , and imidacloprid con...

This study investigated the development of fungal community composition in arable soil during the degradation of straw residue. We explored the short-term responses of the fungal community over 28 days of decomposition in soil using culture-independent polymerase chain reaction in combination with a clone library and denaturing gradient gel electrophoresis (DGGE). Fungal cellobiohydrolase I (cb...

The implications of the propagation of uncertainty for the e ciency of stochastic water pollution control were analyzed. The empirical analysis focused on nitrogen pollution of the Baltic Sea from Swedish crop farms. A two moment model (mean and variance) of the distribution of coastal load was developed and integrated with an economic model of arable land-use choice. It was shown that uncertai...
