    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

  How can an  adhesive masking paper   help saving time in covering indoor surfaces? Well, that ’ s because is kind of an  “ all-in-one masking tool ” , paper and masking tape combined together. This tool is, in fact, a classic masking paper, but with an adhesive strip on it: this means that you spend less time to put it in place and make it stick to the surface you need to cover. pre-taped masking paper is a good product to start practicing with this masking technique: resistant to water-based paint, it prevents leak through and protects against overspray. And that ’ s only the beginning, because adhesive masking paper offers several advantages of which you can no longer live without. Let ’ s see them. It offers fast masking of critical areas As you may imagine,  slef  adhesive masking paper   helps to cover large areas in one step, such as floors or wide walls. What you may not know yet is that is also easy to use to cover doors and windows. You can remove it without leaving adhesive

A new shower can take your bathroom from boring to glamorous. There are so many possibilities for your  shower glass door  design that you may not know where to start. Before making a decision, you may be wondering if you should purchase framed or frameless glass shower doors.We've summarized the pros and cons of frameless and framed shower doors. Commonalities Both are made of tempered glass. They are available in a variety of glass designs. The doors open in many different ways. Framed and frameless shower doors can be sealed with a protective coating. Both types of doors require caulking. Both types of doors can provide a good view of the shower stall.  Difference Materials Framed doors are made of thinner glass, as the frame supports the door. The frame itself is usually made of aluminum and can be powder coated in a variety of colors and finishes. The frame can be smooth or textured, and the glass is sealed in the frame to prevent leakage. Frameless doors are made of the same

    Redispersible polymer powders are polymer emulsions which have been converted by a series of process such as high temperatures and pressures, spray drying and surface treatment to powdered thermoplastic resin materials. When mixed with water, these powdered organic binders can redisperse in water back into new emulsions with essentially identical properties to the original copolymer emulsions. The addition of  redispersible polymer powders   into mortar can increase the cohesiveness, cohesion and flexibility of mortar. First, it can improve the water retention of mortar and form a film to reduce evaporation of water. Second, it can improve the bond strength of mortar. The redispersible polymer powder was invented by a German named Wacker Hemie in 1953, which makes it possible to produce polymer modified dry-mix mortar. The history of redispersible polymer powder is only over 50 years up to now. In 1953, the world ’ s first batch of practical redispersible powder was invented in Ger
