Lemon Grass makes a great source of carbon for the garden compost pile in the urban garden. Leur décomposition sera donc assez lente. Various annual/biennial cover crops make a nice addition to the compost pile: buckwheat, clover, small grains like oats (if you cut them while they're green -- before they become mature, toughen, and turn into straw which is high carbon). Tear it and mix it with fresh manure or grass clippings, or lay it on the bottom of a pile if you’re composting in a damp region. Composting it is fine, just ensure there’s no plastic mixed in with it. Browns - Carbon sources. Layer manure with carbon-rich brown materials such as straw or leaves to keep your pile in balance. Nitrogen-rich materials are called greens because most of them are greenish in color. A C:N ratio of 20, where C and N … soy). Materials that are juicy or derived from animals tend to be nitrogen-rich, as opposed to dry, woody materials that have more carbon than nitrogen. Il faut que la quantité de l'élément chimique carbone (C) soit 20 à 30 fois plus importante que la quantité que l'élément chimique azote (N) en fonction de leur composition chimique [voir Tableau]. Do not, however, let the green material dry out or you'll be adding more carbon to the compost. Le carbone est abondant dans les plantes âgées. Dans la réussite du compost, la proportion entre ces deux éléments, c'est à dire le rapport carbone / azote, joue un rôle essentiel. your own Pins on Pinterest your own Pins on Pinterest Compost scientists have determined that the fastest way to produce fertile, sweet-smelling compost is to maintain a C:N ratio somewhere around 25 to 30 parts Carbon to 1 part Nitrogen, or 25-30:1.
