Why is Composting So Beneficial
Compost is a very environmentally safe source of nitrogen because compost-nitrogen is in organic form and must be mineralized before it has the potential to leach and to contaminate water supplies (such as groundwater).
Mineralization (the conversion of organic forms of an element into inorganic forms) occurs slowly in natural systems. That is just one reason why compost is so much better than chemical fertilizers.
Why is Compost Called “Black Gold”
Compost is sometimes referred to as “black gold” because it recycles leaves, food scraps and grass clippings into a perfect food and organic mulch for all our plants.
Compost is the only “black gold”, manure is also a source of plant nutrients but good quality compost is always far better.
