Effect of Different Carbon and Nitrogen Inputs on Soil Chemical and Biochemical Properties in Maize-Based Forage Systems in Northern Italy

Abstract

In agroecosystems, manure application and straw return affect carbon (C) and nitrogen (N) cycling and affect soil organic matter (SOM), nutrient supply and losses to the environment. We examined effects of different organic sources on crop production, N uptake and surplus and SOM in maize systems
