In this research work we determined concentration of NPK nutrients in tea waste. The main objective of work was determining cost effective and potential alternative to chemical fertilizers. The study concluded with high concentration of NPK nutrients in the waste material like tea waste. The information will be very valuable for agriculture industry.
Fertilizers add nutrients to the soil to endorse soil fertility and boost plant growth. Today fertilizer plays very vital role in modern agriculture to improve crop yield. With advancement in agriculture use of chemical fertilizer increased several folds especially in developing countries like India. The overuse of chemical fertilizers recently generated some serious issues in the field of agriculture like hardening of soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well. In the crops traces of chemical fertilizers creating serious issues for health. In order avoid these problems use organic fertilizers playing key role as these are environment friendly, economical, non hazardous.
In this research our aim is to evaluate concentration of nitrogen, phosphorous and potassium in tea waste. Tea waste which thrown after use can be used as effective organic fertilizer. The main objective Is to find effective, economical alternative fertilizer to chemical fertilizer.
2. MATERIAL AND METHODS:
Tea waste is collected from local tea stalls. Tea waste washed with distilled water to remove impurities, then sundried for 4 hours. The dried powder then dissolved in distilled water in the ratio 2:10. The solution was diluted in the ratio 14:1 with distilled water. The soil testing kit was purchased from Agrinex corporation Luck now India. The contains different vials and capsules separately for Nitrogen, Phosphorous and potassium. The Capsule is filled with different chemical particular for each nutrient. The capsule was opened and content was added to vial. Then diluted solution was added to each vial. The color change due to reaction was observed and compared with standard color monograph given on the kit. There were 4 parameters was observed on the monograph of kit high, medium, low and trace depending upon color of testing vial. The results were obtained by comparison with standard.
3.1. Estimation of total potassium
From figure 1 it can observed that diluted solution contains high amount of potassium.
Figure .1 Evaluation of Potassium by comparing with standard color.
3.2. Estimation of Nitrogen:
From figure.2 it is clearly seen that diluted solution contains high concentration of Nitrogen.
Figure 2 Estimation of Nitrogen
3.3 Estimation of Phosphorous:
3.4. Estimation of pH
The pH of diluted tea waste solution was observed about 5.5
Figure.4 Estimation of pH
From our research work and above results it can be concluded that tea waste contains very high concentration of N, P K. It has huge potential to be used as fertilizer by taking cost benefits. also it is obtained from organic source hence it has no hazardous effects on soil in comparison to chemical fertilizers.
