Application of a Nano-Enhanced Fertilizer in the Development of Agricultural Low-Carbon Economy in the Yangtze River Economic Belt

Abstract

The application of fertilizers can increase the yield of crops. Nano-fertilizer is a nano-organic fertilizer, which is an organic fertilizer with very fine particles. The effect of chemical fertilizers is better than that of general chemical fertilizers, which can effectively improve soil organic matter and is beneficial to the growth of crops. Organic fertilizers mainly refer to commercial organic fertilizers produced by high-temperature composting and fermentation of organic solid wastes such as livestock and poultry manure, crop straw, etc., eliminating toxic and harmful substances and being rich in nutrients including organic acids and peptides. Low-carbon economy refers to an economic model that uses various means to reduce greenhouse gas emissions and achieve good ecological operations under the guidance of the concept of sustainable development. With the increase in the global population and the continuous growth of the economic scale, environmental problems and consequences caused by the use of conventional energy such as fossil energy are constantly recognized by people. Under this background, the low-carbon economy emerges as the times require. This paper aims to study the application of nano-enhanced fertilizers in the development of agricultural low-carbon economy in the Yangtze River Economic Belt. In today’s low-carbon economy, the combination of nano-efficiency fertilizers and agricultural production is conducive to improving the utilization rate of chemical fertilizers and reducing carbon emissions. This paper analyzes the carbon sink capacity of farmland ecosystems and the elements affecting the growth of LCA. This provides a basis for the exploration of farmland ecosystems. It expounds the relevant concepts of low-carbon economy and briefly discusses the agricultural carbon emissions in the Yangtze River Economic Belt. The experimental results in this paper show that the enteric fermentation of dairy cows will produce 60 kg of methane and 15 kg of feces. Sheep enteric fermentation produces 4 kg of methane and fecal emissions of 0.13 kg. According to the data, the carbon emission of dairy cows is much greater than that of sheep.
