  • Health of European streams revealed by leaf breakdown

    A recent study, which assessed 100 streams across Europe, reveals that a key ecosystem process, leaf litter breakdown, is slowed when nutrient concentrations in the water are either very low or very high, has the highest potential at moderate nutrient concentrations and is inhibited in heavily polluted waters, implying that the relationship between nutrient levels and ...

  • LEAF announces significant progress in sustainable farming

    LEAF (Linking Environment And Farming) has revealed another year of significant progress in its mission to deliver more sustainable food and farming. The area of land around the world growing LEAF Marque crops increased by 28% since last year,according to the findings of its latest annual Global Impacts Report, which was launched today.  LEAF reports strong and steady growth in the number of ...

  • Water content thresholds recommended for Gardenia jasminoides

    More efficient irrigation management has become a primary focus in sustainable container plant production as growers look for ways to improve resource use and mitigate negative environmental impacts of fertilizers and pesticides that are often found in nursery runoff. Among the new technologies for increasing irrigation efficiency is the use of soil moisture sensors for automated irrigation. The ...

  • How container-grown plants capture sprinkler irrigation water

    As the container nursery industry faces severe restrictions on water use, researchers are looking to identify ways to minimize watering needs and eliminate excess watering. The authors of a new study say that understanding container-grown plants' capacity to "capture" sprinkler irrigation water can give growers important tools that help them adjust irrigation rates, reduce water use, and produce ...

  • Simulated Seawater Flooding Decreases Growth of Vegetable Seedlings

    Crop production in coastal areas is threatened by seawater intrusion, which increases soil salinity. Excessive salinity in soil and irrigation water, in combination with waterlogging, can significantly affect the growth and quality for agricultural crops, especially those vegetables that are sensitive to salinity. A new study determined salt-tolerant vegetable seedlings for coastal area ...

  • Abscisic acid treatments can prevent tomato blossom-end rot

    Plants are subjected to numerous environmental stresses -- drought, extreme temperatures, and excess light can all affect plant growth and quality. Looking for methods to improve the quality of tomato plants, researchers at the University of Tennessee turned to abscisic acid, a plant hormone known to help plants acclimate to these types of severe environmental stresses. The research results and ...

  • Cooler Weather Conditions, Late Planting, Impacts Insects on Crops

    Rainy, cooler weather experienced recently throughout the region means slugs may be on the rise in some field crops, says an entomologist with the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. The rains combined with colder temperatures are ideal slug weather, said Kelley Tilmon, a field crop entomologist with Ohio State University Extension and the Ohio ...

  • Wetland plants involved in marsh restoration

    Differences in the way wetland plants accumulate pollutants are helping researchers understand how vegetation can be used to help restore contaminated marshes. In a study by Belgian researchers, certain plants, including bulrushes, were identified as being potentially useful for locking away metal contaminants below the surface, thereby helping to reduce spread of these pollutants through food ...

  • Vermicompost leachate improves tomato seedling growth

    Worldwide, drought conditions, extreme temperatures, and high soil saline content all have negative effects on tomato crops. These natural processes reduce soil nutrient content and lifespan, result in reduced plant growth and yield, and ultimately translate to lower profits for tomato producers. As an alternative to unsustainable practices such as the use of synthetic fertilizers, producers are ...

  • L.E.A.F. announces ecommercial contest for California high school students

    Leaders of Environmental Action Films (L.E.A.F.), a project of Inside the Outdoors Foundation, is proud to announce its 2010-2011 “ECOmmercial” Contest. L.E.A.F. has teamed up with Volcom, etnies and Planet Connect to present their second annual Public Service Announcement competition, giving youth a voice on environmental issues.  This year’s contest extends its invitation ...

  • Selective breeding could save trees from drought

    Trees with high wood density tend to survive better under drought conditions. In a new study on Douglas-fir tree populations, research suggests that the trees could be selectively bred for high density wood to increase resistance to drought. With predictions that the frequency of droughts could increase over the coming century, such strategies to protect tree populations could aid climate change ...

  • Cactus could feed East African livestock, say scientists

    A succulent, wild-growing cactus that has been widely dismissed as a noxious weed could sustain African livestock during drought, according to scientists at the Kenya Agricultural Research Institute (KARI). A paper by John Kang"ara and Josiah Gitari, animal nutritionists at KARI, concludes that Opuntia species — the prickly pear or paddle cacti — have extreme tolerance to drought and ...

  • Rejuvenating arid badlands: from barren slopes to living forest in 80 years

    A reforestation project has revitalised its surroundings just 80 years after its inception. In the late 1920s, the Saldaña badlands in northern Spain were a barren region, with a thin layer of intensely weathered soil, and only 5% vegetation cover. Now that cover has increased dramatically to 87%, the soil quality is improving, and the water flow in the area has stabilised, bringing ...

  • Root strength in OSR and winter cereals

    We should never underestimate the importance of roots. Good plant roots are essential for water and nutrient uptake and as such have a significant influence on crop health and yield. Whatever the autumn weather, stimulating the development of deeper root systems will improve the plant’s ability to access the nutrients and water required for establishment and early growth. ...

  • Managing Late Blight of Potatoes and Tomatoes

    Late blight is one of the most serious diseases of potatoes and tomatoes worldwide, resulting in significant yield and quality losses annually. In Alberta, late blight occurs infrequently, but can have devastating impacts in the years when it reaches epidemic levels.  “This disease is caused by a fungal pathogen called Phytophthora infestans,” says Robert Spencer, ...

  • Eco friendly advice for healthy lawns and greenscapes (PA)

    Beautiful lawns are a big part of summer, but the average lawn can eat up your free time and cost a bundle to maintain. Going with eco-friendly methods can actually save you time and money, and help the environment. A thick, full lawn reduces soil erosion, filters contaminants from rainwater and absorbs airborne pollutants like dust and soot. Grass is also great at converting carbon dioxide to ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...
