Smart Agricultural Waste Management: A Comprehensive Guide

Agricultural Waste Management,The agricultural sector, while a cornerstone of food security and economic growth, is also a significant contributor to environmental challenges. Improper management of agricultural waste leads to pollution, greenhouse gas emissions, and loss of valuable resources. The imperative to adopt sustainable practices has given rise to the concept of Smart Agriculture, which integrates technology and innovation to optimize agricultural processes. This article delves into the critical area of agricultural waste management, exploring effective techniques aligned with the principles of Smart Agriculture.

Agricultural waste encompasses a diverse range of materials, including crop residues, livestock manure, food processing byproducts, and packaging materials. The mismanagement of these wastes can have detrimental impacts on soil health, water quality, air quality, and human health.
