Olfactory indicators, also known as smell indicators or odor indicators, are substances that change their smell in the presence of certain chemicals or conditions. They are commonly used in chemistry experiments to detect the presence or absence of specific gases or to determine the pH level of a solution. Olfactory indicators provide a visual and olfactory cue, making it easier for scientists to identify and analyze substances. READ MORE...

The evolution of atomic theory is a long and winding road that has been travelled by some of the greatest minds in history. It began with the ancient Indians in 600 BC who gave the concept of “Parmanu” to Greeks who first proposed that matter was made up of tiny, indivisible particles. The 19th and 20th centuries saw significant advances in our understanding of atoms. READ MORE...

A periodic table is a tabular arrangement of chemical elements organized by their atomic number, electron configuration, and recurring chemical properties. The periodic table is one of the most important tools in chemistry, and it is used by scientists and engineers in a wide variety of fields. PERIODIC TABLE Sandbh, CC BY-SA 4.0, via Wikimedia Commons The periodic table is divided into rows called periods and columns called groups. The elements in a particular group have similar chemical properties, and the elements in a particular period have similar electronic configurations. The periodic table is a powerful tool for predicting the properties of elements. For example, if you know the atomic number of an element, you can use the periodic table […] READ MORE...

A popular topic among agriculture specialists and home gardeners these days is the furore on organic fertilizer vs. chemical fertilizer.   Now each fertilizer certainly has its pros and cons, but before we delve deeper into that, let us first make a few definitions.  What is organic fertilizer? Organic fertilizers are substances containing nutrients derived from the remains or by-products of an organism. Examples of organic fertilizers are cottonseed meal, blood meal, fish emulsion, manure and sewage sludge. Organic fertilizers are naturally rich in nitrogen, phosphorus, and potassium, the three major nutrients needed in plant growth. Organic fertilizers depend on microorganisms found in soil to break them down and release nutrients. What is chemical fertilizer? Chemical fertilizers are synthetically produced plant […] READ MORE...

Using organic fertilizers is a widely accepted practice in the agricultural industry. Farmers use them to cultivate their fields and row crops, winemakers utilize them for growing grapes, and horticulturists apply a liberal dose of these during the landscaping of their orchards or turfs.   Liquid organic fertilizers are a safe and effective way of providing your plants with the best nutrient supply without harming them or increasing the soil’s acid content. Liquid organic fertilizers act as agents to effectively increase the content levels of nitrogen, phosphate, and potassium. Because these three substances are the three major nutrients that plants need, liquid organic fertilizers thus provide plants with an abundant food supply essential for their growth.  Liquid organic fertilizers are especially […] READ MORE...
