Precision agriculture (PA) involves the management of agricultural fields including spatial information soil properties derived from apparent electrical conductivity (ECa) measurements. While this approach is gaining much attention in management, farmed podzolic soils are under-represented relevant literature. This study: (i) established relationship between ECa and moisture content (SMC) measured using time domain reflectometry (TDR); (ii) evaluated estimated SMC with measurements obtained...
Biobased residues derived from organic urban waste materials can be processed to produce soil amendments that enhance fertility and carbon sequestration. However, the extent of sequestration by biobased depends on interaction between their physicochemical properties, climate, agroecosystem management practices. Our objective was predict how different (compost, anaerobic digestate, or biosolids), compared nitrogen fertilizer, affect stocks under continuous cropping crop rotation in Ontario,...
In temperate cold regions, the gradual resurgence of soil microbial activity during spring freeze-thaw events is frequently associated with greenhouse gas emissions. Enhanced fluxes are related to mineralization bioavailable substrates, which may be elevated when amended organic residues (e.g., biobased such as compost, digestate, biosolids). The objective this study was determine impact residues, compared urea fertilizer, on emissions events. field treatments included (170 kg N ha −1 y ),...
Abstract Biobased residues are local and cost‐effective sources of soil amendments that can efficiently provide nutrients to crops, enhance health serve as alternatives mineral fertilizers. The objective our study was comprehensively evaluate the crop productivity temperate agroecosystems amended with different types organic (biobased residues), including composted food waste (compost), biosolid slurry (biosolids) liquid anaerobic digestate (digestate), compared nitrogen fertilizer....
