  • 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 ...

  • Copper-zinc interactions increase toxicity in soils, say researchers

    Agricultural soils accumulate trace metals, particularly copper and zinc, as a result of their presence in wastes (sewage biosolids and manures) and fungicides that are applied over long periods of time. Regulations and guidelines for tolerable concentrations of these potentially plant-toxic elements in soils are based on the assumption that the toxic effects of the metals are substantially ...

  • Understanding why rye works as a cover crop

    Agricultural Research Service (ARS) scientists may soon find a way to enhance the weed-killing capabilities of a cereal grain that enriches the soil when used as a winter cover crop. Rye is often grown in winter and killed in the spring, so the dead stalks can be flattened over soybean and vegetable fields to block sunlight and prevent spring weeds from getting the light they need to germinate. ...

  • Escaped nanoparticles hazardous to crops, says study

    Nanoparticles that escape during the manufacture and use of consumer products would substantially reduce the growth of wheat were they to end up in soil, according to Chinese scientists. The production, use and disposal of nanomaterials from sectors such as cosmetics and electronics can lead to their release into air, water and soil. Their presence in wastewater, and their direct use in ...
