Nitrogen release dynamics and carbon sequestration by legume and non-legume cover crops under pure and mixed planting conditions

Abstract Synchronizing crop residue decomposing and releasing nitrogen with subsequent cash needs provides benefits for ecosystems, but it is difficult to carry out. This study aimed investigate the trend of decomposition vetch ( Vicia sativa ), rye Secale cereal e) mixed (rye + vetch) cover residues as well release after incorporating them into soil during 12 weeks potato growth season by using mesh bag method. Vetch decomposed very quickly in spring their released due higher content consequently a lower Carbon/Nitrogen (C/N) ratio. However, at slower rate compared treatment, was immobilized mainly C/N A better understanding crops dynamics leads maximizing effects nutrient uptake main crops. The results this showed that input level fertiliser can be reduced implementing management strategies farming potatoes crops, which will reduce harmful environmental increase economic benefit farmers.
