Green Manures – Rye

Rye early spring

Ken works to keep soil covered.  He often says, “Naked soil is dying soil.”  He means that either mulch or green manures will maintain moderate soil temperatures to promote microbial life, prevent erosion, add nutrients, – so many things!  Ken often mulches.  He also likes to plant green manures.

What are green manures?  It is a crop intended to promote soil health rather than a crop to be harvested.  Green manures are often legumes like peas or clover, or sometimes  they are grains like wheat, rye, buckwheat, or oats.  Sometimes different seeds are combined like peas and oats.  Some green manures like rye have extensive root structures and can break up hard soil.  Legumes like peas or clover add nitrogen to the soil.  All add root mass, sometimes called white manure.

Rye tall enough to mow

This white manure adds organic matter to the soil.  Organic matter promotes life in the soil.  It also acts like a porous sponge – it will retain soil moisture during drought and will soak up heavy rain to avoid saturated soil.
