Benefits an costs of Fertilizer Benefits Balanced fertilization has

positive effects on the environment.

Fertilizer use allows farmers to continuously achieve high yields on the same land for many years, meaning that farmers don't need to clear new land.

Fertilizers also help in preserving land for wildlife.

Costs Chemical fertilizers sterilize the

natural minerals and nutrients found in soils.

When it rains the fertilizer runs into our drains contaminating our water and killing fish.

How to make Organic fertilizers

The three major nutrients for making organic fertilizers are: nitrogen, phosphorus and potassium (Lime is also used)

Select a place to leave your leftovers ( You can also make a strong bin out of wood, if you do, you must leave the lid open to allow oxygen to fertilise it.)

Two items needed to make organic fertilizers are green remains and brown leaves and other leftovers. A part of the green should have be mixed with two parts brown and this mixing will go on until it becomes damp.

First put a layer of leaves, that are 4 inches thick and then put garden soil over the top again and again, then add two inches of green or brown leaves.

Mix well, with manure or a garden fork. You can also add kitchen green leftover and also eggshells to it. Mix the pile up and down every week. Within two months your natural fertilizer will be readyInformation found at:

The use of science knowledge.

Recycling of carbon and nitrogen

Decaying recycles raw materials and gets rid of waste at the same time. Decay is the breaking down of organic matter by decomposer micro-organisms. Bacteria and fungi feed on the organic materials make energy. During this process both carbon and nitrogen are recycled. The carbon from waste products is made into carbon dioxide which plants need for photosynthesis. Nitrogen from proteins in dead or waste products is changed to nitrates in the soil which plants use to make new proteins.
