Solomon WR, Burge HA, Muilenberg ML. [51] As of 1992[update], studies on phenoxy herbicides were too few to accurately assess the risk of many types of cancer from these herbicides, even though evidence was stronger that exposure to these herbicides is associated with increased risk of soft tissue sarcoma and non-Hodgkin lymphoma. First, take arborist chips and lay them down. Common allergenic pollen and fungi. Ryegrass is cross-pollinated by wind, so genes shuffle frequently. Thanks for the reply.

Since mycellium breathe CO2 & produce oxygen beneath the soil it seems likely that if you inoculated cardboard to be used as a sheet mulch the fungi would take care of the oxygen needs. Let me explain haha. Brian. Generally, the conditions that promote herbicide transport include intense storm events (particularly shortly after application) and soils with limited capacity to adsorb or retain the herbicides. Postemergence: These herbicides are applied after weed seedlings have emerged through the soil surface. But what does/might research say about the impact on soil in the plot? Thats actual, natural topsoil. Of course, the rate at which they break down probably depends on a whole range of variables including the exact composition of the leaves, the soil organisms present, how damp the substrate is above and below. [22] Resistance to herbicides is often attributed to lack of rotational programmes of herbicides and to continuous applications of herbicides with the same sites of action.

I asked our local arborist about getting some wood chips from him, and he discouraged me, saying that there were many diseases that might be brought into our yard and infect our trees from them. However, the facts remain that cardboard is made to reduce both moisture and gas exchange, and that earthworms (as well as other soil organisms) need oxygen in the root zone.
