Causes for Land Degradation

Basic Components Types Quantity of Fertilizer How it cause land degradation

The Spreading of Chemical Fertilizers

Water pollution

Contamination with impurities

Fertilizer dependency

The nutrients in fertilizers can cause problems for natural habitats and for human health.

Phosphate fertilizers usually contain impurities such as fluorides, cadmium and uranium.

Effectively farmers unknowingly became dependent on 'bought in' water soluble.

land degradation

Soil acidification

Trace mineral depletion

Over fertilization

Regular use of acidulated fertilizers generally contribute to the accumulation of soil acidity.

Inorganic fertilizers may not replace trace mineral elements in the soil which become gradually depleted by crops.

Over-fertilization of commercial pot or container-grown crops results in high concentrations of soluble salts in the potting medium.

Data Analysis

land degradation

Soil Erosion:

Desertification

land degradation

Solutions

soil conservation programs. Maintain a vegetation cover . prevent overgrazing. crop rotation.

Reduce overgrazing and deforestation. Limit human activities. Plant more trees and grasses to anchor soil and hold

water. Plant leguminous plants.

land degradation

Solutions

Reduce irrigation. Switch to salt-tolerant crops . Use humic acids to fix anions and cations and

eliminate them from the root region of the plants.

Educate farmers on how to use chemical fertilizers.

Change the soil after examination by specialized people.

Determine the quality of the soil. Taken a soil sample containing elements. Fertilizers needed for such soil if it is single or

compound.

Salinization

Fertilizer quality Vegetative growth stage

Flowering stage Harvest stage until the end of the seasonUrea

Urea 800 grams / 3 times a week for two weeks

1.6kg / three times a week for two weeks

600 grams / three times per week for 8 weeks

Potassium 300 grams / three times a week for two weeks

600 grams three times a week for two weeks.

400 grams three times a week until the end of the harvest

after two weeks of planting option begins urea and potassium fertilizer according to the table below:
