….The negative ecological consequences of mineral fertilizers have reached menacing proportions. This concerns synthetic nitrogen in particular. It reduces the humus content and biodiversity in the soil, causes soil acidification and gives rise to emissions of nitrous oxide, a potential greenhouse gas causing climate change that will harm future food production. The rise in soil acidity diminishes phosphate intake by crops, raises the concentration of toxic ions in the soil, and inhibits crop growth. The depletion of humus in the soil diminishes its ability to store nutrients. Greenhouse gases derived from synthetic nitrogen fertilizers harm the environment…”

Recently published scientific papers have calculated the N-NUE index (Nitrogen-Nutrients Use Efficiency) for different open field crops. According to their results, about 70% of the nitrogen distributed to plants gets diluted and leeched in waters (surface waters or waterbeds) and even in air. This means that globally, for each percentage point of the N-NUE ratio increase, about 1,000,000 tons of urea could be saved.
There is also increasing recognition that the nutrient values of harvested food are linked to the biological activity of soil microbes, soil organic matter, the mineral composition of the soil, fertilization practices and the genetics of the plant. Exhausted soils depleted of needed minerals and organic material cannot grow healthy, nutrient rich food. SOURCE:www.nutritionsecurity.org
The TRISAP Board and management also strongly believe that one of the next great advances in agriculture will be in the utilization of plant and soil microbes, and that there is a great potential for applying appropriate technologies in this area to its existing resource base.
Strong economic and environmental drivers are therefore focussing on the need for increased efficiency in the use of fertilisers, particularly nitrogen.
This problem is only exacerbated in the rapidly growing Asian region by land now being at a premium everywhere and with severely depleted soils, so yields per hectare of existing farmed areas need to be increased to meet the inevitable increase in demand.
TRISAP’s natural fertiliser and soil amendment and conditioner range of products will play an important part in addressing these issues through products based on their chemical and physical properties.
Technologies and products that enhance crop production and soil health in the Asian region have high and growing investor appeal.
