Why should we protect soil?

Soil degradation reduces agricultural yields and threatens farmers’ livelihoods. Soil that has been leached of its nutrients cannot support crops, or plants that prevent desertification. Healthy soil is essential to ensure a steady supply of food and biodiversity.

What are three ways to prevent soil erosion?

How to prevent soil erosionCrop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water.Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.More items…•

How can we prevent soil erosion from rain?

Cover bare patches of soil, hill sides, and spaces between plants with 1 to 2 inches of mulch. This will protect soil from overhead watering and rain, keeping it in place. It also minimizing evaporation and feeding soil at the same time. Consider adding extra seed to cover ground and fill in bare patches in your lawn.

How can we protect the soil?

What causes soil depletion?

It can be the loss of organic matter, decline in soil fertility, and structural condition, erosion, adverse changes in salinity, acidity or alkalinity, and the effects of toxic chemicals, pollutants or excessive flooding. Soil degradation can involve: water erosion (includes sheet, rill and gully erosion) wind erosion.

Why should we prevent soil erosion?

Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil. It decreases agricultural productivity, degrades ecosystem functions and amplifies hydrogeological risk, such as landslides or floods.

How can we protect plants?

Cover low plants with straw or mulch if there is a quick frost. If a frost strikes unexpectedly, protect your smaller plants with emergency insulation. Straw or mulch traps heat and keeps the soil and plant warm. Cover plants that are only a few inches tall completely.

How do humans help soil?

Farming, construction and development, and mining are among the main activities that impact soil resources. Farming is very important to society because almost all of the world’s food is grown on farms. Over the 10,000 years humans have been farming, people have continually improved their farming methods.

What are the two methods of soil erosion?

Rainfall and surface runoff Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

How can we solve the problem of desertification?

Strategies to reduce desertificationPlanting more trees – the roots of trees hold the soil together and help to reduce soil erosion from wind and rain.Improving the quality of the soil – this can be managed by encouraging people to reduce the number of grazing animals they have and grow crops instead.More items…
