#Effects of potassium fertilization in pear trees

“#Effects of potassium fertilization in pear trees” ‘Rocha’ pear harvest in Southern Brazil, 2017. Credit: P.B. Sete. The amount of exchangeable potassium (K) contained in native soil does not always meet the necessary nutrient demand for a pear tree, which makes the use of K based fertilizer essential. Brazilian farmers face daily challenges to increase…

#Secondary school admissions system is still a work in progress

“#Secondary school admissions system is still a work in progress” New research, examining how parents choose secondary schools, questions England’s ‘success rate’ for admissions and suggests the ‘good news’ revealed today may not tell the full story. Researchers believe the system could, easily and cheaply, be made to work better. A new report entitled ‘School…
