ABSTRACT
Knowledge is necessary at all stages and by all concerned in farming, because it is never quite certain when a small error can have serious consequences. Over the centuries, knowledge in agriculture was gained very slowly indeed, profiting only by a painful process of trial and error. Knowledge and experience are good in themselves, but their correct application to the present conditions is essential. The use of knowledge to good effect can be hampered by other deficiencies: the lack of information, the lack of time, the lack of power, the lack of materials or the lack of money. It is easy to say that every possible use should be made of existing knowledge, but less easy to put into practice. A good farmer thinks in principles but acts in detail, and the more attention he gives to such details, and then the better will be the final result.
