الصين تحوّل قش القمح إلى “ذهب أسود” يغذي المحاصيل ويخدم المناخ

ما يعرفه ريفو عن الخبر

طور باحثون صينيون فحمًا حيويًا من قش القمح يقلل من انبعاثات غاز أكسيد النيتروز المسبب للاحترار العالمي.
يساهم الفحم الحيوي المحمل بالمنغنيز في تحسين قدرة التربة على الاحتفاظ بالنيتروجين اللازم لنمو النباتات.
أظهرت النتائج أن المادة المعدلة تزيد من قدرة تبادل الإلكترونات بنسبة 80% مقارنة بالفحم غير المعدل.
أدت إضافة الفحم الحيوي إلى زيادة نشاط المسار المرتبط بتحويل النترات إلى الأمونيوم وتقليل الانبعاثات الغازية.

قدّم باحثون -باستخدام الفحم الحيوي المصنوع من قش القمح- حلا لإحدى المشكلات الزراعية، وهي فقدان التربة للنيتروجين، مما يسبب انبعاث أكسيد النيتروز، أحد غازات الدفيئة التي تسهم في الاحترار العالمي.
