fertilizer, n.All

Trees near rivers with salmon grow three times faster than trees without them due to bears leaving carcasses around to decompose

Earthworms are useful in that their secreted 'slime' contains nitrogen and also holds clusters of soil particles together in formations called aggregates

Tomato plants fertilized with human urine produce up to four times more fruit and have higher levels of beta-carotene & protein than traditional fertilizers.

The tunneling of earthworms deeply in the soil brings subsoil closer to the surface, thereby mixing it with the topsoil

Fertilizer is important to a garden, but the best fertilizer is the gardener's shadow.
