The Role Of Gypsum In Agriculture: 5 Key Benefits You ...

One of gypsum's main advantages is its ability to reduce aluminum toxicity, which often accompanies soil acidity, particularly in subsoils. Gypsum can improve some acid soils even beyond what lime can do for them, which makes it possible to have deeper rooting with resulting benefits to the crops, Dick said.

In a very recent study, Yang et al showed that administration of 10 mg/kg of curcumin results in only 0.36 µg/ml of curcumin in the blood serum. These studies show that the route of administration has a role to play in the metabolism of turmeric. Also, the absorption of curcumin is a major factor responsible for low bio-availability of turmeric.
