Some fertilizer prices have been to historic highs and some fertilizer prices have been to historic lows in the last six months of 2008. World economic forces, credit issues, demand destruction, transportation costs, labor strikes, commodity price swings, and other influences have changed once stabile fertilizer markets. Some market comments indicate that price swings may be settling in late winter as final 2009 crop and credit decisions are made. Growers should focus on nutrient management decisions that economically produce crops.

The Fertilization Decison

Each producer manages nutrients through answering a few simple questions:

Are fertilizers necessary to produce the crop?

How much fertilizer is needed if necessary?

What fertilizers are available if needed?

When is the best time to apply fertilizer?

How should the fertilizer be applied?

Fertility management is important. However, variety selection, water management, insects, nematodes, diseases, weed pressure, and climatic conditions also affect crops.HISTORY OF C:C is a popular general purpose programming language. It is one of the most popular computer languages today, because it is a structured, high level, machine independent language.

The root of all modern language is ALGOL, introduced in early 1960s. ALGOL was the 1st computer language to use a block structure. Subsequently, several other languages were announced after 1960s. In 1967, Martin Richard developed a language called BCPL i.e. basic combined programming language mainly for writing system softwares. In 1970, Ken Thompson created a language using many features of BCPL and called it simply B. B was used to create early version of UNIX operating system.

C was evolved from ALGOL, BCPL, and B by Dennis Ritchie at the Bell Laboratories in 1972, strongly associated with UNIX. During 1970s, C had evolved into the TRADITIONAL C. With the publication of the book The C Programming language by Brian Kerningham and Dennis Ritchie in 1978, it becomes more powerful.

In 1983, American National Standards Institutes (ANSI) appointed a technical committee to define a standard for C. The committee approved a version of C in December 1989, which is now known as ANSI C. It was then approved by International Standard Organization (ISO) in 1990.

IMPORTANCE OF C

The increasing popularity of C is probably due to its many desirable qualities. The C compiler combines the capabilities of an assembly language with the features of a high level language and therefore it is well suited for writing both system software and business packages. In fact many of the C compilers available in the market are written in C. Programs written in C are efficient and fast. This is due to its variety of data types and powerful operators. It is many times faster than BASIC.

There are only 32 key words in ANSI C and its strength lies in its built in functions. C is highly portable; this means that C programs written for one computer can be run on another with little or no modifications. C language is well suited for structured programming, thus requiring the user to think of a problem in terms of function modules or blocks. This modular structure makes program de-bugging, testing and maintenance easier.Another important feature of C is its ability to extend itself. We can continuously add our own functions to C library, thus our programming task becomes so easier and simpleSYSTEM REQIUREMENTS:
