Nitrogen is an essential element for plant growth. Nitrogen deficiencies in pear orchards result in poor tree vigour and yield while high levels of nitrogen lead to excessive vegetative growth and can adversely affect fruit quality. Accurate calculation of nitrogen requirements will help avoid excessive applications that can result in leaching of nitrates and subsequent environmental damage.
