Recently, most agrarian countries have witnessed either declining or stagnant crop yields.
Inadequate soil organic matter (SOM) due to the poor physical, chemical, and biological …

Interest in biochar stems from its potential agronomic benefits and carbon sequestration
ability. Biochar application alters soil nitrogen (N) dynamics. This review establishes …

Almost half of global nitrogen (N) fertilizer is applied to rice, wheat and maize, but a large
proportion is not directly taken up causing detrimental effects on the environment. To …

Intensive agriculture and urbanization have led to the excessive and repeated input of
nitrogen (N) into soil and further increased the amount of nitrate (NO 3−) leaching into …

Ruminants excrete as much as 70–95% of the nitrogen (N) they consume. The urine patch is
the conduit through which much of this N is recycled in grazed pasture systems. This chapter …

Dissolved organic matter (DOM) is defined as the organic matter fraction in solution that
passes through a 0.45 μm filter. Although DOM is ubiquitous in terrestrial and aquatic …

Nitrogen is the most limiting nutrient in most agro-ecosystems and thus critical for sustaining
high yields. Conventional agricultural practices use synthetic fertilizers to ensure an …

China is facing one of the largest challenges of this century to continue to increase annual
cereal production to about 600 Mt by 2030 to ensure food security with shrinking cropland …

Cereal production that now sustains a world population of more than 6.5 billion has tripled
during the past 40 yr, concurrent with an increase from 12 to 104 Tg yr− 1 of synthetic N …
