Building soil organic matter
increases water retention capacity, and creates more stabile, fertile soils, thus reducing vulnerability to drought, extreme precipitation events, floods and water logging.
The bottom of the lamp is covered with pumice, which has a
high water retention capacity, meaning that plants require watering only once every three weeks — something that a busy office would appreciate.
Soil life is enormously enhanced, and
water retention capacity is increased.
«The removal of vegetal cover through burning would likely increase water runoff when it rains, potentially reducing
their water retention capacity and invariably the soil moisture,» Ichoku said.
