Soil waterlogging due to excess moisture resulting in hypoxic soil conditions can have detrimental effect on development of many dryland plants growing in locations with temporary water logged soils. Oxygen stress in hypoxic soils can lead to decreas

One of the most visible signs of climate change in nature are shifting growing cycles. In northern areas, mostly energy limited environments, the growing seasonality is usually defined in 3 different ways:- frost free period: time period between last
