An oil spill is the accidental or intentional discharge of petroleum products into the environment due to human activities. Although oil spills are actually just a little percent of the total world oil pollution problem, they represent the most visible form of it. The impact on the ecosystems can be severe as well as the impact on economic activities. Oil spill cleanup is a very difficult and e...

The influence of coloured-plastic mulching on physical and biochemical characteristics tomato fruits were investigated. During the study, crop was grown in an open field under five mulching, one organic mulch a no-mulch treatment. Harvested analysed for various physico-chemical post-harvest quality parameters. Results evidenced that sphericity tomatoe non-significantly (P<0.05) affected by h...

This study aimed to quantify forage yield, economic performance, biological efficiency and competitive ability in cactus intercropped with millet, compared their monocrops, both without mulch, under irrigation. The experiment was conducted over two years semi-arid of Brazil. experimental design randomised blocks four replications six treatments: monocropped mulch; millet mulch mulch. individual...

The choice of variety for agricultural systems with multiple crops may differ from the one used in sole crop because of the changes in environmental conditions brought about by interspecific plant competition. Information about varietal performance under living mulch conditions as well as the suitability of the results of the official variety testing, conducted under conventional cropping condi...

Soil erosion and phosphorus (P) runoff can be severe in potato production systems in the Northeast USA, which are characterized by intensive tillage, minimal ground cover, low crop residue return, and steep slopes. We used rainfall simulators in the greenhouse and field to assess sediment and P movement associated with two conservation practices: straw mulching and application of polyacrylamide...

Despite being one of the most pro®table crops for the southeastern USA, cotton (Gossypium hirsutum L.) is considered to create a greater soil erosion hazard than other annual crops such as corn (Zea mays L.) and soybeans (Glycine max (L.) Merr.). Reduced tillage systems and cover cropping can reduce soil erosion and leaching of nutrients into ground water. The objectives of this study, which wa...
