even foods are perishable and semi-perishable like juicy fruits, vegetables, mangoes, tomato, papaya and many more, which very quickly gets spoilt. it is therefore important to improve and expand facilities for storage and preservation of food. food preservation helps in: 1. increasing the self-life of foods thus increasing the supply.

dry rot and wet rot. dry rot serpula lacrymans is the most famous of the rots and is the most serious. if left to grow dry rot will cause thousands of pounds worth of damage, dry rot can cause timber decay at lower moisture content than wet rot that is why the cause of the problem needs to be identified and rapid drying of the area is needed.
the preservation of places significant to their heritage has been important to north dakotans since before establishment of the state. the state's native american peoples, for example, had maintained shrines and traditional cultural properties long before the arrival of euro-americans.

the moisture content of wood is another property of timber which effects the quality of timber to a great extent. moisture is contained in timber as free moisture in cell cavities and as imbibed moisture in cell walls. wood is a highly hygroscopic substance.
the primary objective of wood preservation is to achieve, within every piece of timber, a defined retention of preservative chemical within a defined penetrated zone of the cross section, each being predetermined by a number of factors, most particularly the hazard level to which the timber is to be treated.
preservation of timber the object in preservation of timber is to save it from rot, whether wet or dry. there are many different ways and patented methods of trying to prevent these forms of decay; but, before proceeding to explain them, it will be as well to say a few words on wet and dry rot.

coconut wood is classified as non-durable. in order to prevent any attack of fungi, mould or insects during drying, a dip treatment previous to stacking is necessary. timber used in the interior, e.g. for wall-panelling or furniture, should only be treated if it is of low density. in this case a boron treatment against insects is advisable.

yarrow notes that conservation is distinct from preservation in the sense that preservation involves maintaining natural areas for their own sake, which includes protecting them from human use and intervention. yarrow says that all organisms that are not directly acted upon by humans,

timber preservation. a range of different chemical treatments has been developed to enhance the durability and service life of timber. such chemical treatments impregnate the wood cells, making them resistant to decay, insects, weather or fire. while chemical treatments add to the cost of the timber, they can significantly increase its lifetime.
timber is treated with a wood preservative generally has it applied through pressure and vacuum treatment. the chemicals that is used to pressure-treat wood are solvent-borne and water-borne .
