Soil scientists and researchers at a post-rally discussion in Rajshahi on Wednesday stressed the need for protecting soil health for increasing crop production to ensure food security of the country.
They expressed concern over declining soil productivity due to indiscriminate use of chemical fertilisers and pesticides round the year, reports BSS.
The soil scientists and researchers were addressing the rally organized to mark the World Soil Day-2018. ‘Be the Solution to Soil Pollution’ was the main theme of the day. Regional office of Soil Resource Development Institute (SRDI) organised the discussion in its conference room in the city.
Chaired by Dr Abu Tawab Khandaker, principal scientific officer of SRDI, the meeting was addressed, among other, by deputy director of Department of Agriculture Extension Shamsul Haque, principal scientific officer of Bangladesh Wheat and Maize Research Institute Dr Ilias Hossain, SRDI Senior Scientific Officer Dr Nurul Islam and senior scientific officer of Bangladesh Agriculture Research Institute Dr Shakhawat Hossain. During his keynote presentation, Md Kamruzzaman, principal scientific officer of SRDI, said soil nutrients have gradually been declining due to multifarious reasons creating a negative impact on the soil productivity.
He viewed disproportionate use of chemical fertilizers and harmful pesticides for cultivation of high yielding varieties of different crops and vegetables are mainly blamed for the continued decline in soil nutrients. “Organic matter requirement is at least 2.5 per cent in a normal soil, whereas the content in the area was found less than 1.3 per cent and even less than one per cent in some soils,” he revealed.
