There are many nutrients needed for flowering and pollination. Within this article we will focus on the three most important nutrients for fruit trees at the beginning of flowering: zinc, boron and calcium.
Bio-stimulant products are getting used by farmers more and more across Australia in addition to their traditional fertilizer programs.
However, there is still confusion for farmers around this sector as CEO Gary Murdoch-Brown of EcoCatalysts Pty Ltd – a leading Bio-Stimulants company with offices in Australia, South Africa, USA and the UK explains.
It has been well documented that effective pollination is a limiting factor in lifting yields in tree crops.
With spring frosts just around the corner endangering your crops, there is still time to arrange frost protection for your orchards.
South African experience
In most areas where apples and pears are growing in South Africa, the trees do not get enough winter chill to break dormancy satisfactorily. This results in delayed foliation, a protracted bloom period and poor yields.
High sustained production
When root restriction is combined with management of the fruit trees, the soil and the method of irrigation, high-density plantings can be highly productive and easy to manage for a long time. You can achieve this by:
Many plants (for example cherry), have nectar–secreting plant glands that develop outside flowers and are not involved in pollination.
These glands are called extrafloral nectaries or EFN.
What are pheromones?
Pheromones are natural volatile chemicals used by an organism to communicate with others of the same species.
When it comes to fertiliser nutrients, everyone talks about the big three: NPK (Nitrogen, Phosphorus, and Potassium).
It’s true that these elements are needed in the biggest quantities for crop growth. We can calculate the requirements by looking at crop removal, soil/tissue tests, and growth stages; and there is no doubt that they are important.
