  • Fertilizer placement affects nutrient leaching patterns

    Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease ...

  • Many Countries Reaching Diminishing Returns in Fertilizer Use

    By Lester R. Brown When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It ...

  • Nitrogen use by warm-season grasses for biomass production

    Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

  • Haifa Group Introduces a Mobile App Supporting Growers` Fertigation Practice

  • Soil carbon storage is not always influenced by tillage practices

    The practice of no-till has increased considerably during the past 20 yr. Soils under no-till usually host a more abundant and diverse biota and are less prone to erosion, water loss, and structural breakdown than tilled soils. Their organic matter content is also often increased and consequently, no-till is proposed as a measure to mitigate the increase in atmospheric carbon dioxide ...
