TruebusNews – Do not underestimate the rocks round us. Zeolite, a rock that’s broadly present in Tasikmalaya and its environment, West Java, seems to be wealthy in advantages. One in all them as a fertilizer saver.
Waste of fertilizer use continues to be a basic drawback for Indonesian farmers. For instance, one hectare (ha) of rice vegetation truly solely requires 250 kg of fertilizer. However on common, farmers use 300 kg of fertilizer per hectare of rice vegetation. The rationale, they doubt the efficacy of the fertilizer.
Scientifically, we are able to agree with the farmers’ doubts. Fertilizers include vitamins akin to Nitrate (NO3-) and Phosphate (PO43-) that are vital for plant development. Sadly, these two vitamins are simply separated from fertilizers as a result of they’re simply carried away by water. This causes the vegetation to be much less fertile and finally wastes using fertilizers.
To avoid wasting on fertilizer use, the sphere of floor chemistry provides an answer. With the assist of geology, this subject makes use of zeolite rocks as prima donna. Zeolite is a porous Alumina Silica rock that comprises many minerals akin to Calcium (Ca), Magnesium (Mg), Sodium (Na), and Potassium (Ok). In Indonesia, 4 districts in West Java are well-known for his or her abundance of zeolites, specifically Bogor, Ciamis, Tasikmalaya and Sukabumi districts.
Based mostly on analysis by chemists and geologists, zeolites can take in nitrate and phosphate. They do numerous methods to change the zeolite. One in all them is by modifying its chemical properties. With this analysis, they hope that the nitrates and phosphates in fertilizers will not be simply misplaced to water.
In 2010, Chemistry college students on the College of Indonesia (UI) performed analysis to change zeolite. They coated the zeolite with a positively charged polymer (polycation), specifically PDDA (Poly Diallyl Dimethyl Ammonium Chloride). The constructive cost of this polycation is ready to appeal to negatively charged phosphates. In consequence, zeolite can take in phosphate simply. The scholars plan to proceed this analysis for testing for nitrates. If the outcomes are passable, they hope to cooperate with zeolite miners and fertilizer producers for additional product improvement.
The usage of zeolites to avoid wasting fertilizer may be very straightforward. Based on DR.Astiana Sastiono, a educating employees on the Division of Soil, School of Agriculture, IPB, we are able to combine zeolite with fertilizer or straight sprinkle it on the bottom. As well as, the required zeolite can be small. Based mostly on analysis, 100 grams of zeolite can retailer 19,306 grams of ammonium sulfate (ZA)1 fertilizer.
Zeolite as a fertilizer saver gives successive advantages. Little fertilizer is used nevertheless it comprises a variety of vitamins. The land used can be more and more fertile. The tip result’s an increasing number of high quality. From an environmental perspective, water air pollution as a consequence of nitrates and phosphates will also be diminished.
As acceptable, the utilization of this zeolite will be maximized. With the cooperation of the federal government, businessmen, and scientists, Indonesia can make the most of this mineral wealth. Unmitigated, we are able to enhance the welfare of Indonesia’s economic system, agriculture, and atmosphere on the identical time.
