Soil disturbance resulting from tuber crop harvesting is a major threat to soil health. The depth of soil intervention is a critical factor that further strengthens the effects of such disturbance and makes harvest one of the most harmful cropping operations. In the case of potato, soil moisture is a determining factor for root and stolon developme...

Water productivity enhancement in farming systems is one of the most critical challenges facing the agricultural sector in the twenty-first century. Precision irrigation based on soil matric potential (SMP) measurements effectively enhances water productivity. However, the temporal effect of an SMP-based comfort zone on potato crops is lacking. Thi...

Soil organic carbon (SOC) has a significant effect on the carbon cycle, playing a vital role in environmental services and crop production. Increasing SOC stock is identified as an effective way to improve carbon dioxide sequestration, soil health, and plant productivity. Knowing soil water is one of the primary SOC decomposition driver, periods in...

Potato is one of the most cropped plants worldwide. Hundreds of different varieties are cultivated only in North America. Potato growers usually crop multiple varieties on their farms to answer the market demands for potato’s specific physical properties. However, few pieces of information are available regarding the optimal management of irrigatio...

(This work has been prepared for Canadian Agri-food Policy Institute and the original article can be found at https://capi-icpa.ca/wp-content/uploads/2019/11/2019-10-09-CAPI-Wetlands-CAPI-Doctoral-Fellows-2017-19-group-paper_WEB.pdf) Wetlands are becoming more and more vulnerable environments. They were, and still are, largely impacted by the expan...

The root system and its architecture play an essential role in the plants physiology, from stability for aboveground structure to water and nutrient transport and storage. However, due to the opaque characteristic of the soil or other growing media and the fragility of some of the root system structure, non-destructive temporal observation remains...

In agriculture, water consumption for crop production represents 69% of all water use. Precision irrigation systems based on available soil water have been developed to improve crop production, reducing water use. Besides the improvements in irrigation management, a better resolution of the optimal water level is required, and revealing the impact...

Losses of nitrogen fertilizer from agricultural watersheds are among the main causes of water quality degradation in Quebec. Under maize crop, leached nitrate can reach up to 185 kg N ha−1. The synchronization of the nitrogen fertilization with crop uptake would be a way to optimize the use of nitrogen fertilizer and reduce nitrate leaching. Coupli...

The human use of fresh water has expanded at a rate twice that of the population increase. Nowadays, 70 percent of the 3 830 cubic km of water use is being taken by the agricultural sector. Among the major crops, the potato stands on top of the calories production per liter of water. Ironically, potato yields are particularly sensitive to soil wate...
