- ... A cultural practice for cooling cranberry plants and avoiding yield losses due to overheating is to turn on sprinkler irrigation for a few minutes when a critical temperature threshold is reached. The purpose of this study was to determine: (i) the critical leaf temperature to start irrigation for evaporative cooling in cranberry production, (ii) the combined effects of heat and water stress, and ...

- ... Several studies have shown that adding biochar as soil amendment to agricultural land can increase the sustainability and productivity of cropping systems by sequestrating C from the atmosphere into the soil, by minimizing the emission of greenhouse gases (GHG), by improving soil properties and soil fertility via its effects on porosity, particle aggregation, soil structure, water and nutrients re ...

- ... Experiments were conducted on 1-year-old western red cedar (Thuja plicata Donn.) seedlings to determine the response of illuminated foliage to reversible changes in total photosynthetic foliage area (L(A)). Reductions in L(A) were brought about by either shading the lower foliage or by reducing the ambient CO2 concentration (c(a)) of the air surrounding the lower part of the seedling. In the latte ...
