INTRODUCTION The case of critical land has become a national issue since several decades. One source of the emergence of critical land management of forestland is not appropriate, as a result, the critical land in Indonesia is increasing every year. The real impact of the existence of critical land is environmental degradation and decline in socio-economic conditions. Critical land can lead to a decrease in land productivity and the main problems encountered in the critical land is the land of easy slopes, soil reacted sourly and poor nutrient elements. Nutrient needs during the growth of the plant are one of the important things that determine the success of an agricultural production. Silica is one of much-needed nutrient elements of a plant. Benefits of silica among others to stimulate …show more content…
RESEARCH METHODS 2.1. The synthesis of Nano silica-Chitosan Composite As much as 0.5 grams of Chitosan acetic acid 20 ml added 2% and stirred until it formed hydrogel. Added by as much as 0.5-gram silica and stirred until homogenized. The mixture obtained is entered into the syringe and melted into the NaOH 1 M and shaped granule. Composite washed with aquades. Dried in the oven at the temperature 50⁰C for 24 hours. Composites are characterized by XRD, FT-IR, and SEM 2.2. analysis of Silica In Composite By Atomic Absorption Spectroscopy Each as much as 0.1 gram of the mixed aqueous solution of HCl added composite 2.5 M and 0.5 M HF with a total volume of 10 ml for through a process of dissolution for 1 week. The total concentration of Si contained in the solution to be analyzed using atomic absorption spectroscopy (AAS) on long wave 213.86 nm. The making of the Si standard solution done by dissolving 0.1 grams of The metal in solution 20 ml HCl 37% and added aquades to the volume of 100 ml of The solution thus obtained 1000 ppm. The solution is diluted so that its concentration is obtained several times with variations 0.2; 0.4; 0.8; 1.2; 1.6 and 2.0
For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
Then the mass of the copper metal and the percentage of Cu were obtained and compared throughout different groups and a mean and standard deviation was calculated for the
After copper ions were filtered, approximately 15mL of .5 M was added to the filtrate, which made the mixture acidic. Then, 20 mL was added into the filtrate to raise the pH of the mixture.
We know from the statement that the volume of the silver nitrate solution was 50 mL
If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle
The reaction between Hydrochloric Acid and Sodium Carbonate led to the formation of gaseous Carbon Dioxide, aqueous water, and aqueous solution of Sodium Chloride as a result of all compounds containing alkali metals solubility. Lastly, Copper Sulfate and Sodium Carbonate reaction produced an aqueous sodium sulfate solution and a solid precipitate of Copper (II) Sulfite because of all alkali metals and sulfates ability to be soluble and the rule that any compound containing CO₃ is insoluble. In the end, the hypothesis that if we react mystery chemicals with one another, we will be able to identify the reactants and products, create balanced equations, and observe properties because of our prior knowledge learned throughout the course of the unit and using the known chemical reaction was accepted by the data
If a plant is receiving a higher concentration of salt minerals in the water a nutrient imbalance will occur inside the plant, thus resulting in poor or little plant growth. Salinity level tests should regularly be carried out by home gardeners to ensure the best quality produce, salinity level test results which display salt levels more than 320 parts per million should not be used to water plants. Mineral nutrients are another important factor to successful plant growth, in home gardens, these nutrients are found in the soil and additional fertilisers, however, these levels of nutrients can be accidentally altered by excess salts, resulting in plant dehydration and possibly death. Found in soil, potting mix and other mediums in which plants typically grow in contain oxygen in which the plant needs to successfully grow.
Introduction: The unknown acid molarity will be determining by titration method. Titration is a process depends on concentration of known solution to another solution until the solute in the another solution completely react. Standard solution is the solution of known concentration that used in titration. In this experiment, NaOH was the titrant (base) however, the two analyte which used were HCl and H2SO4.
Further, in order to absorb water and other nutrients from the soil the roots were developed to anchor the plant to achieve this purpose. Material transportation: In the water, different parts of the plant get nutrients and water directly from their environment,
As farmers have to mass produce in order to supply for the growing population today, fertilizer is essential to improve the quality and growth of the
Introduction: Description: Deforestation is defined as the permanent destruction of forests in order to make land available for other uses. According to the Food and Agricultural Organization of the United Nations (FAO) 18 million acres of forest are lost each year. This equals to approximately 36 football fields of forest being cleared each minute. Though deforestation occurs all over the world, it’s the tropical forests which are being particularly targeted. Due to this countries such as Indonesia, Brazil, the Democratic republic of Congo and Thailand have a very
In most foods, microbial contaminations occur predominantly at the surface, meaning using edible films such as chitosan allows minimal space between the foods’ surface and its’ environment. However, the coating has weak mechanical properties, and is permeable for gas and water vapour. Blending chitosan with starch improves its mechanical properties and allows a better novel food preservative. ADVANTAGES: - As chitosan is the second most abundant carbohydrate after cellulose, it’s not unusual that its waste exceeds 25bn tonnes per year.
Sustainable forest management requires three major criteria which are the maintenance of ecological processes within the forest (soil formation, energy flow, biogeochemical cycles (carbon, nutrient and hydrological cycles), maintenance of biodiversity of forest, improving the net social benefits derived from the mixture of forest uses within the constraints by considering the future. Forest provides habitats for more than half of the fauna and flora on the Earth (SCBD, 2001). Forest biome plays an important role in mitigating climate change by serving as carbon sinks (Hassan et al., 2005). Forest land is the most fundamental natural resources which become reduced mainly due to anthropogenic pressures. For proper management of land, it is essential to have information about existing land cover and about the naturalness of the land.
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
LITERATURE REVIEW Inorganic fertilizers provide rapid nutrition and give plants with the nutrients needed to grow healthy and strong. Inorganic fertilizer, also called as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals and it is which help a plant to grow faster. Effective use of Inorganic Fertilizers Effectiveness in using these chemicals has good and bad effects on the environment especially on the health of a human being. Fertilizer has turn into essential to modern agriculture to feed the growing population.
