When you see blue, purple, or white on a butterfly, that's a structural color, while orange, yellow, and black are pigment, Prudic says. The nanostructure of the chitin, or wing scale, Prudic says, affects what light is reflected and how it's reflected.
Longevity of a beneficial microbe or microbes in the soil or potting mix environment is a benefit for long-term crops. Bacteria tend to release their protective secondary metabolites for up to 4 weeks after application, even though they.may persist in the soil environment longer.ecause bacterial and fungal microorganisms (a.k.a. microbes) in soils and potting media are constantly vying for food, water, and space, soils are regarded as dynamic living environments.
By avoiding the use of topsoil, the risk pathogenic microorganisms in this media may be reduced, avoiding problems with diseases like damping-off. In addition, topsoil is relatively heavy and dense so it can contribute to poor aeration and drainage in a potting mix.tâs a good idea to test each batch of potting mix, and to be able to compare results from mixes that performed well to those that didnât. The cost is low, about $15 or $20 per SME sample. The information in this table was developed at Michigan State University in the 1980's.
