Assessment System for Cover Crops Growth and Chemical Composition.

Cover crop has been paid attention due to add soil organic matter, conserve soil residual nitrogen during fallow season when the threat of leaching is considerably, and enhance soil organic matter. However, these benefits may vary depending on cover crop growth and chemical compositions. Therefore, cover crop growth monitoring may be a very important technique because cover crop benefits are strongly associated with the soil nutrient cycle in agro ecosystem. To make appropriate decisions for cover crop management, simple and convenient cover crop growth detective methods should be developed. This paper aims to evaluate the potential of portable spectral camera techniques to measure cover crop chemical composition in different time and growth periods.
