The new citrus export levy for 2021 has been announced: R1,64 per 15kg carton – a significant increase from 74c per 15kg carton in 2020. The industry as a whole welcomes the increase and predicts that it could result in an additional income of about R134 million.
Researchers at the University of California studied the role of the tree’s microbiome in the progression of citrus greening disease. They used amplicon technology to study the microbiome during the progression of HLB, and found that harmful microbes increased, while beneficial microbes decreased during the disease progression.
Despite the Covid-19 pandemic and all the uncertainties it caused, the 2020 citrus season turned out to be one of the best that South Africa has ever had. On estimate, South Africa exported 21.3 million cartons more than the previous season. Better access to US markets due to additional ports of entry, and access to Philippine markets, have contributed to an increase in demand for South African citrus.
Cover crops are specific crops not intended for sale but for soil improvement and sustainability. They are increasingly common in the agricultural fields of the Midwest and other grain-producing regions because of the wide range of benefits not just for the soil, but also the cash crop. In those systems, cover crops improve water and nutrient retention, promote microbial activity, reduce weed growth and insect pests, and improve plant growth. Similar impacts have been found in tree crops like apples and peaches, where cover crops are planted in row middles.
