I know, it's basic science, and maybe not turf related but, has anyone used compost for a customers "mulch"? Or is this a shot in the dark? Was the customer pleased? Reason being.. "until bacteria have completed their breakdown of organic matter, crops should not be planted in soils to which only partially decomposed materials have been added. Likewise, when sawdust, straw, or other organic mulches are spread around plants in a garden to control weeds and conserve soil moisture, the soil nitrogen will be less available to the growing plants until the mulches have been decomposed." 'Introductory plant biology', Stern pp482 (nitrogen cycle) I might start doing this in my mothers garden. (She still makes me do the work.. haha.. good for me huh?) I used to use chicken poo but it wasn't;t broken down all the way... compost might be an alternative? Mulch in the spring, grow.. and till it in the fall, or next spring? Once again.. have you done it? And with what results?
