A way to grow more food on the same piece of land is for farmers to practice multiple cropping, defined as growing multiple crops sequentially, within a year. Multiple cropping can increase production and income and has additional benefits – increased crop diversity, improved functioning of agricultural systems, spare land for biodiversity or other uses and reduced use of inorganic fertiliser and pesticides.
A CSIRO study found that increasing multiple cropping in suitable areas could lead to up to 30% more global food production without additional agricultural land. Many low- and middle-income countries in Africa, South America, and Asia have potential for increasing multiple cropping which could support food supply and food security
Irish company MagGrow has won the
International Innovation Award at the 2020 Fieldays for its patented technology
that reduces waste from conventional pesticide spray drift by up to 70%, reduces water
usage by up to 50% and can improve crop coverage by 20%+ leading to healthier
and less diseased crops.
Farmers typically see a return on
investment in one year or less through chemical, labour and water savings. It
is easy to install and maintain and can be fitted to new or existing sprayers.
There is virtually no maintenance with no moving parts, cables, electrical
wires, or power supply required.
