Phosphorus deficiency-Soya bean

Oireet
Leaves usually show a dark green to bluish tint. The displayed photo shows yellow chlorosis. Because of the effect that P deficiency has on retarding overall growth, striking foliar symptoms that are evidence of deficiency in certain other nutrients, for example N and K, are sometimes observed.

Syyt
Phosphorus deficiency The uptake of P is inhibited in acidic as well as in cool, wet soils.

Oireet
Plants suffering from P deficiency usually show a dark green to bluish tint on their foliage. In the displayed picture, leaves show an even chlorosis and a dark, brownish tint on the interveinal fields.

Syyt
Phosphorus deficiency Soybeans require relatively large amounts of P, especially at pod set. The uptake of P is inhibited in acidic as well as in cool, wet soils.

Oireet
Plants suffering from P deficiency usually show a dark green to bluish tint on their foliage. In the displayed picture, leaves show an even yellow chlorosis and a beginning light brown necrosis on the marginal area of the leaf base.

Syyt
Phosphorus deficiency Soybeans require relatively large amounts of P, especially at pod set. The uptake of P is inhibited in acidic as well as in cool, wet soils.

Oireet
P deficient plants suffer from growth retardation and sparse foliage. Leaves usually show a dark green to bluish tint. In the displayed case, older leaflets show interveinal chlorosis and necrosis. Light brown necrotic blotches coalesce along the leaf margin.

Oireet
Leaves usually show a dark green to bluish tint. In the displayed case, older leaflets show interveinal chlorosis and necrosis. Light brown necrotic blotches coalesce towards the leaf margin.
