INTRODUCTION. Nitrogen (N) fertilization in agroecosystems can lead to non-desirable environmental impacts such as water pollution by nitrate leaching and the emission to the atmosphere of the greenhouse gas nitrous oxide. The application of nitrification inhibitors (NIs) such as dimethylpyrazole phosphate (DMPP) and dimethylpyrazole succinic acid (DMPSA) has been proven to be an efficient...

[Introduction] Soil organic carbon (SOC) sequestration is essential for sustaining soil health and food supply in agroecosystems (Turmel et al., 2015). The amount of organic C stored in soil reflects a net balance between C inputs and outputs (Kuzyakov and Domanski, 2000). Soil is a complex matrix with a spatially heterogeneous distribution of SOM at different spatial scales (Schlüter et...

In intensive vegetable production systems, cover crops are usually incorporated into the soil by disking prior to the subsequent crop. In recent years, silage tarps have gained popularity amongst farmers in Quebec as a suitable tool for no-till cropping systems. Termination of cover crops by roller-crimping is another strategy used by organic farmers. However, these practices have not been...

Introduction
Intensive agriculture has been promoted since the green revolution in the 1960s to boost crop yields and satisfy increasing food demand (Mann, 1999). Such intensification led to modifications in agricultural practices with higher fertilization, increased pest control and intense varietal selection among others. Additionally, the increase in the overall agricultural land cover led...

(1) Modern food production largely rely on a linear nutrient flow, with nutrients entering the field as bought fertilisers, or potentially as farmyard manure, but with little return of nutrients from the society. Returning organic waste products is a way of closing nutrient cycles between agriculture and society, contributing to a circular economy where resources are reused (Rosemarin et al.,...
