SunBoost and Maize
The form of stabilised Nitrogen,
rather than nitrate Nitrogen in Sunboost, will help root development and the
calcium
within the product will help streghthen the cell walls to resist
any stress that the plant may suffer in the coming growing
season.
Maize productivity is improved when plants are
supplied with a mix of nitrate and ammonium N usually as a result of greater
kernel numbers.
Nitrogen applied as a foliar urea spray is largely
absorbed in the NH2 form and is thus more readily incorporated into
protein.
Sunboost is urea solution stabilised with calcium
chloride. Standard urea solutions lose N in the ammonium form, this occurs even
under cooler conditions in the morning or evening but is greater at higher
temperatures. By reducing this loss the plant is able to utilise the N in
Sunboost more efficiently thus reducing the rate required.
Calcium is essential to increase cell wall strength
in all crops. This makes plants more resistant to attack by both pests and
diseases and also increases the plants resistance to stress.
Calcium increases the plants uptake of N
Maize, cereals and potatoes have also been shown to
respond favourably to chloride nutrition.
Application of 25-50l/ha Sunboost will supply the
plant with readily absorbed ammonium nitrogen and calcium
Ammonium n is more readily utilised by the roots and
encourages the development of more adventitious roots, thus increasing the
plants uptake of other nutrients and restoring the balance
Maize plants also require S for the efficient
utilisation of N and boron for healthy cob growth. Where maize is grown in
areas deficient in S applications should be applied as soon as possible
