- NVARCHAR — Data is stored in a Unicode encoding. Every language is supported. A Good Idea. What about storage space? VARCHAR is generally efficient, since the character set / encoding was custom-designed for a specific locale.

What is the Difference Between nchar (n) and nvarchar (n)? If the number of characters entered in an NCHAR data type column is less than the specified column length, spaces are appended to it to fill up the whole length. Another difference is in the storage size wherein the storage size for NCHAR is two times n bytes while for NVARCHAR is two times the number of characters entered (in bytes). You should use NCHAR data type when the data values in a column are expected to be consistently close to the same size.

What Is Biochar? Biochar is a Powerfully Simple Tool to Combat Climate Change. The carbon in biochar resists degradation and can hold carbon in soils for hundreds to thousands of years. Biochar is produced through pyrolysis or gasification — processes that heat biomass in the absence (or under reduction) of oxygen. In addition to creating a soil enhancer, sustainable biochar practices can produce oil and gas byproducts that can be used as fuel, providing clean, renewable energy. When the biochar is buried in the ground as a soil enhancer, the system can become carbon negative..
