Crop Mix
Late drilling of cereals due to adverse weather conditions may result in
poorly established crops going into winter.
These crops are more susceptible to adverse weather conditions and
disease than well established crops.
Soils which lock up manganese (high pH) also tend to lock up copper and
zinc.
Manganese is implicated in the control of water status of the plant and
in protein and carbohydrate metabolism. It may also affect chlorophyll
synthesis.
Manganese deficient plants often have a floppy and paler green
appearance. But plants deficient in manganese also accumulate nitrate in the
leaves so the leaves may still appear to be dark green.
Zinc deficiency reduces protein synthesis and leads to the accumulation
of nitrates. New leaves tend to be longer and narrower than usual.
Copper deficiency affects protein metabolism and copper is involved in
lignin synthesis. Deficient plants may have twisted leaves and root growth may
be affected.
All three elements affect the frost hardiness of plants.
All three elements affect the crops resistance to diseases.
