    Sulfur has become an important crop nutrient applied to corn fields across Minnesota. Recent research has shown a benefit from applying sulfur in fields low in organic matter and in high residue situations where mineralization and release of sulfate sulfur from organic matter are limited. What can make sulfur application challenging is that the form of sulfur available for crop uptake is sulfate. Sulfate is an anion and, like nitrate, can leach deep in the soil profile where crop roots cannot reach. The addition of sulfur fertilizers to fall phosphorus and potassium applications leads to questions about what the best form of sulfur is. Choosing the right form is critical to ensure crops are not short of this necessary nutrient early in the growing season. Commercial sulfur fertilizer   sources include either elemental or sulfate forms of sulfur. The difference between the two is that sulfate sulfur forms, such as gypsum or ammonium sulfate, contain readily available sulfur, while e

One size does not fit all. This goes for rubber stoppers used in various industries. The  rubber stoppers  are made of different shapes and diameters to give the perfect fit. Rubber plugs are used to stop spillage and seal the containers so it is important the right type of rubber stopper is used. Therefore, in this article, I will tell you what rubber stoppers are and nine different types of rubber stoppers. So, let’s find out.     What Is a Rubber Stopper? A rubber stopper is a small, tapered plug used to seal the openings of test tubes, flasks and other laboratory glassware. Stoppers made of cork are also available for this purpose. However, rubber stoppers are preferable for applications that require a tighter seal or a greater degree of chemical resistance.   Purpose The primary purpose of a  rubber stopper  is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamination of samples by protecting the conte

    Different terms used for  arresters  are sometimes confusing even professional engineers and electricians use them interchangeably. Now let’s discuss all these arresters in details.   Table of Contents   What is a Surge Arrester? What is a Lightning Arrester? Main Differences between Surge Arrester and Lightning Arrester Should You Use Surge Arresters or Lightning Arresters?   Surge Arrester   1. The  surge arrester  will be installed nearer to the equipment to be protected and the transmission tower line enter in to the substation point. 2. It protects against high voltage transient (example: lightning strike on the transmission conductor) typically, it is indirect protection of lightning strikes. 3. It should be installed each phase of the circuit. i.e if you have 2 parallel switch yard then you should install 6 number of surge arrester (first run 3 phase and second run 3 phase) . Lightning arresters   1. The lighting arrester is doing the exact duty of surge arrester from outsid
