Influence of rainfall interception by endemic plants versus short cycle crops on water infiltration in high altitude ecosystems of Ecuador
Owing to their high water retention, the volcanic ash-soils of the Northern Andean highlands (páramos) can be considered as natural ‘water storage tanks’ for drinking water and for irrigation. Vegetation plays an important role in transferring rain to the soil and in controlling the soil water content. To assess this role, we quantified the stemflow process under rainfall simulations for ...

One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas
All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. This figure doubles when looking at irrigated cropland, which produces 40 ...

Polyphenol oxidase activity and colour changes of peeled potato (cv. Monalisa) in vacuum
Minimal processing of vegetables has some undesirable physiological consequences. The shelf life of peeled raw potatoes is limited by the onset of enzymatic browning at the cut surfaces. It is generally accepted that polyphenol oxidase (PPO) is the enzyme mainly responsible for this type of browning. This work aimed to study the effect of vacuum storage at 4?C on the colour, which is the main ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...
