Eects of irrigation on phosphorus in soil, soil microbes and plants of semi-natural grasslands
Water and phosphorus (P) are two critical resources for high nature value farming in semi-dry mountains. ey are major drivers of grassland productivity but can negatively aect plant diversity. Soil moisture is known to aect soil microbial activity and plant P nutrition but the eects of irrigation on soil P status, soil microbial P and plant P nutrition in semi-natural grasslands remain larg...
متن کاملAllelopathy—Chemical Warfare Between Aquatic Plants
8 Think about your first reaction if you saw a poster at your local pet shop announcing “New Ornamental Plant Kills All Algae in Your Tank Within 24 Hours—Money Back Guarantee!” How much would you be willing to spend on such a plant? Unfortunately, no such plant has yet been identified. But it is a scientific fact that some plants secrete chemicals that are toxic to other plants. Can we use suc...
متن کاملActivated carbon may have undesired side effects for testing allelopathy in invasive plants
Activated carbon has become a widely used tool to investigate root-mediated allelopathy of plants, especially in plant invasion biology, because it adsorbs and thereby neutralizes root exudates. Allelopathy has been a controversially debated phenomenon for years, which revived in plant invasion biology as one possible reason for the success of invasive plants. Noxious plant exudates may harm ot...
متن کاملSources and modes of action of invasive knotweed allelopathy: the effects of leaf litter and trained soil on the germination and growth of native plants
Invasive knotweeds, native to Eastern Asia, are among the most dominant plant invaders of European and North American temperate ecosystems. Recent studies indicate that one cause of this dominance might be allelopathy, but the possible sources and modes of action of this allelopathy are insufficiently understood. Here, we asked whether the invasive knotweed Fallopia × bohemica can exert allelop...
متن کاملDeep influence of soil microbes.
A single gram of soil is said to contain more than 8 billion bacterial cells, representing up to 50,000 different species1. These microorganisms play important roles, from tweaking how plants interact with their surroundings to influencing the chemical composition of the environment2. Now, the increased affordability of DNA sequencing technologies has enabled scientists to gain a deeper underst...
