It takes Dr. Young and his team seven years to perfect the biodegradation method which he named TTT Technology. In order to speed up the process, at TTT AgriBiotech's headquarters, they use the same enzyme formula to deal with different kinds of waste.

Soil acidification is a sign that soil is degrading and it is a natural process. However, it should happen slowly. If the soil acidifies because of man-made factors, the pH levels of the soil will fall, acidity in the soil will increase, and soil acidification will accelerate. And Mother Nature cannot recover in time.

Climate change is related to how we use our resources. The more we restore organic matter in the soil, the more we reduce greenhouse gases, the more we slow down climate change. Only when the soil is healthy can the plants be healthy, and our food is safe, and then we are healthy.

Acidified soil over time will cause a lot of issues in crops such as growth, poor disease resistance, and increased susceptibility to various pests and diseases. And as a result, farmers will have no choice but to use more pesticides, which increases their production costs. Additionally, acidified soil will make nutrient uptake more difficult for crops, causing farmers to use even more fertilizers. But, the use of more fertilizers exacerbates the problem by adding acidic residues to the soil, creating a vicious cycle. Lastly, acidified soil may lead to malnutrition in crops, causing the price of crops to fall and affecting the livelihoods of the farmers.
