Endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9methano-2,4,3-benzodioxathiepin 3-oxide), a pesticide that is highly toxic to aquatic organisms, is widely used in the cotton (Gossypium hirsutum L.) industry in Australia and is a risk to the downstream riverine environment. We used the GLEAMS model to evaluate the effectiveness of a range of management scenarios aimed at minimizi...

Field experiments were conducted on-farm in the forest zone of Ghana to determine the effects of stubble mulch (in-situ residues from Mucuna pruriens var utilis or natural grass fallow) and method of land preparation on the yield of dry season tomato (Lycopersicon esculentum). Land preparation methods studied were slash burn and ridge; ridge and mulching with the existing residue; and zero till...

The partitioning and quality of aboveground biomass have important ramifications for crop management and biomass conversion. In preliminary studies, Saccharum sp. Miscanthus sp. hybrids exhibited stubble cold tolerance in west-central Arkansas, unlike Saccharum sp. Saccharum spontaneum hybrids. The objective was to examine foliar and stem quality of the C4 grasses Miscanthus sinensis (‘Gracilli...

Horizontal black surfaces are usually very attractive to polarotactic aquatic insects, since they generally reXect highly and horizontally polarized light, and thus imitate water surfaces. We monitored highly polarizing black burnt-up stubble-Welds, but surprisingly never found aquatic insects or their carcasses in the ash, although Xying polarotactic insects were abundant in the area, which we...

Increasing numbers of previously threatened large grazing birds (cranes, geese and swans) are causing crop damage along their flyways worldwide. For example, the number of reported incidents of crop damage caused by common cranes Grus grus, followed by regulated inspections and governmental compensation in Sweden, has increased over the last few decades and was valued at 200,000 Euros in 2012. ...

A one-year study was conducted to measure the effects of balanced supplementation to improve biosustainability of a 110 head goat herd in Mexico in terms of economic feasibility on limited pasturing range land complemented with an alfalfa hay forage bank and grazing corn stubble. Average weight of adult females was 52.410 5 kg, yearlings 40.0 3 kg at ®rst kidding. Average total lactation milk p...

Eastern Washington is compromised by various pollution sources, of which agricultural burning is a particular burden. Smoke from field burning is a nuisance to nearby communities and is a concern for health. This study evaluates levoglucosan (LG) and methoxyphenols (MPs) as potential tracers for apportioning field burning smoke. PM2.5 (particulate matter < 2.5 microM m in aerodynamic diameter) ...

An improvement in growth, condition, raw material quality, and resistance of vegetable plants to adverse stress conditions or agricultural pests can be achieved by using foliar-applied biostimulators. Cover cropping is also of great importance since it contributes, among others, to a better use of environmental conditions and fertilization by plants. In the period 2009–2011, a field experiment ...

Horizontal black surfaces are usually very attractive to polarotactic aquatic insects, since they generally reflect highly and horizontally polarized light, and thus imitate water surfaces. We monitored highly polarizing black burnt-up stubble-fields, but surprisingly never found aquatic insects or their carcasses in the ash, although flying polarotactic insects were abundant in the area, which...
