A model to exhibit the methods of soil conservation?

Question

i want any model ideas

Answer 1

drip irrigation ,,will make a good model,, soil is prevented from getting washed away,,

this method is applicable even for paddey crop..

more over crops grow well in stress conditions, ie limeted water conditions.

Answer 2

this is easy and takes less time

make a heap of soil plant grass or some sort of small plants on one side and keep the other side barren and without vegetation. on pouring water (like rain ) the soil from barren side will get eroded and less erosion will take place on the side where there was plantation. this would show that trees help in preventing soil erosion.

Answer 3

Soil conservation methods

Comprehensive soil conservation is more than just the control of erosion. It also includes the maintenance of organic matter and nutrients in soil. Soil conservation practices also prevent the buildup of toxic substances in the soil, such as salts and excessive amounts of pesticides. Soil conservation maintains or improves soil fertility, as well as its tilth, or structure. These all increase the capacity of the land to support the growth of plants on a sustainable basis.

There are two basic approaches to soil erosion control: barrier and cover. The barrier approach uses banks or walls such as earthen structures, grass strips, or hedgerows to check runoff, wind velocity, and soil movement. Barrier techniques are commonly used all over the world.

The cover approach maintains a soil cover of living and dead plant material. This cover lessens the impact and runoff of rain water, and decreases the amount of soil carried with it. This may be done through the use of cover crops, mulch, minimum tillage, or agroforestry.
