Organic soil care : Organic fertilisers - Plant based products
Introduction
Composted plant wastes and manures, and green manures, are the main ways of adding plant foods to the soil. Organic fertilizers are only used where a soil or plant deficiency occurs which cannot be remedied otherwise - or where you are unable to make or obtain sufficient quantities of bulky organic materials.
Fertilisers suitable for use in an organic garden are of plant, animal or mineral origin. Most of them are waste products. The action of soil living creatures, or the weather, makes their nutrients available to plants, in a 'slow release' way. The mining and/or shipping of some of these products can have an adverse environmental impact, so think carefully before use.
