Essential Role Of Nutrients For Legumes

Important Nutrients For Peas, Beans, Alfalfa, Soya etc.

Major nutrients

# Nitrogen (nodulation)
# Phosphorus
# Potassium

Secondary nutrients

# Magnesium
# Sulphur

Trace Elements

Boron

Manganese

Molybdenum

Deficiencies of nutrients

Molybdenum

Vital for conversion of atmospheric nitrogen into plant usable nitrogen

In legumes this process is carried out by nitrogen fixing bacteria

Nitrogen fixing bacteria are found in nodules on the root surface

Molybdenum - "The Key"

Molybdenum is less available in acidic soils

At pH below 5.6 almost all molybdenum is locked up

Without molybdenum, legumes cannot fix nitrogen

Molybdenum deficiency leads to nitrogen deficiency and yield losses

Manganese And Marsh-Spot

Manganese deficiency during flowering

Causes an internal browning in center of peas

Applications against Marsh-Spot must be made during flowering

Similar disorder occurs in beans

Other Nutrients Identifying Deficiencies

Analysis should be used to detect deficiencies

For most deficiencies yield may be reduced without any visual symptoms

Treating Deficiencies Boron, Manganese, Magnesium

Leguminous crops should be treated for deficiencies when the plants are 10 to 15 cm tall.
