Conventional crop cultivation that is used for mulch production is accompanied by the inevitable and repeated use of pesticides. These agents are needed to eliminate the competitiveness of weeds and pest impact, and their active substances persist in biomass long after harvest. When we use that biomass as mulch, we can be sure that we are bringing a large number of active compounds in the garden. Miscanthus cultivation, on the other hand, does not require the use of pesticides and fertilizers, so it is unlikely that unwanted compounds will come with biomass.
Also, during the main harvest of crops, a large number of classes and seeds remain in the field. By harvesting these residues, the mulch becomes a fertile substrate of seed admixtures. When using mulch, many plants of these crops will likely germinate and sprout. Miscanthus is also advantageous here because it does not produce seeds. Since there is no significant presence of weeds in its plantations, mulch is actually an immaculate material with no risk of unexpected germination.
Miscanthus mulch is pH neutral, and neutral pH helps plant growth because it determines the availability of essential plant nutrients. Most common mulches are acidic in pH, which makes certain nutrients, especially phosphorus, less accessible while increasing other nutrients, such as aluminum and manganese, to toxic levels. Acid pH levels are also undesirable for beneficial soil microorganisms.
