Soil Production Through Decay Science Project Idea

Science project idea on soil produced through decay of organic decay.

Soil Production Through Decay- Science Project Idea

How soil has been produced by decay of organic matter.Plants gain a foothold in the soil formed by the decomposition of rock material and, by their own decay and that of animals which live upon them, add to the soil that part of it which causes it to blacken when burned.This organic part of the soil, or humus, is of special importance in giving it the proper texture and increased power of holding water.It is also the principal source of nitrogen which is so necessary for plant growth.If you will recall your study of bacteria, you will remember that they are necessary in soils in order to decompose the vegetable and animal matter so that this material may be used again in the growth of plants.

Science Project Idea

Research decay and the nitrogen cycle and present your information.
