Abstract
The natural disaster is one of the biggest reasons of social problems in Mongolia.
About 30 natural hazards and disasters occur In our country which is greatly related to the specific of regional localization.

The studying on disaster issues in Mongolia which includes the protection or preventation costs and economic loss due to the disaster, further, the calculation of social net benefits of the costs that are spent of disaster and disaster management.
We are summarizing the research of Cost Benefit Analysis for disaster protection activities as follows:
• The frequency of dzud was once in 8 or 9 years from 1944 until middle of 1980s. But, since then, quantity of frequency is getting high in recent years, especially between 1999 and 2003, when every year have occurred the dzud in Mongolia.
• According the function of the dead livestock in the year when dzud occurred, there will be 13.09 million dead livestock.
• The disaster protection costs that spent for dzud is not enough beneficial.
• The action plan of National Emergency Mitigation Agency needs to be implemented. Because, the CBA results that the net benefit of the plan is 58.9 billion MNT.
• The one of the main reasons for dzud is drought. A way to improve the pasture land that’s for decreasing the drought risk is to move the livestock to other pasture as possible as far.

We carried out a laboratory and field experimentation with seeder-tiller that was equipped with a seed sprayer designed by us in its arrow shaped drill. Such seed spraying allows to expand the area compacted by wedge roller by 6 cm. Both the field and theoretical study confirmed that seed spread out at 5x5 cm or 25 sq.cm. per seed are most optimal from the nutritional point of view.
In the light of increased dryness in nowadays, introduction of irrigation technology increased the crop yield over 2 times and allows productivity at 3.7 tons/ha.
The technical and economical assessments concluded that the three types of seed sprayer designed by us namely, prismatic sprayer, sprayer with tube and cone shaped sprayer increased the grop yield by 75%, 50% and 25% respectively when compared with the standard seeder with arrow shaped drills.

Abstract
Today`s standard design of a pump element dedicated to inject fuel into each sylinder of the diesel engine does not adequately reduce fuel consumption while at an idle or light loading of tractor, but it gives corresponding an amount into engine. Therefore, the main purpose is to increase fuel efficiency and reduce specific fuel concumption.
One feasibile method to reduce inefficiency fuel consumption while under light loading of the wheeled tractor`s diesel engine is a revision to the plunger by making an extra groove in the working surface.
The main goal of the extra groove is to increase the action thus reducing fuel consumption during light loading of the tractor aggregate.
First it is required to select and experiment with several variations to the area above the helical groove of the plunger. Cutting too small an amount from the working surface decreases the chance of economizing fuel and conversely cutting too much would have the negative effect of decreased engine power and a reduction in productivity of the tractor aggregate.

Abstract
In this paper presented are the results of experimental study trials on evaluating the dust contamination in the air surrounding the engine of a tractor working in the field during soil preparation and seeding operations.
The field trials for dust sample collection were carried out by using the simple dust receiver specially designed for this purpose by the authors of this study and placed at the engine air inlet of the tractor.
Statistical evaluations of the experimentel data resulted in the conclusion that the dust contamination (1) at the engine air inlet depends on various parameters including the engine air filter placement (H), soil moisture contents ( ), tractor running speed ( ), air wind velocity ( ), and number of tractors working simultaneously on the field (nm) and we developed following mathematical model.

The dust contents around the tractor engine were ranging from 0.968 g/m3 to 1.281 g/m3 depending on the above mentioned factors. Dust granulation varied between 6 and 53 mkm. The dust receiver was placed at 1.5 m, 1.8 m, 2.0 m and 2.6 m depending on the tractor engine type and mean size of dust collected were 13.6 mkm, 11.2 mkm, 10.1 mkm and 7.5 mkm respectively. It confirms that dust contents and granulation depend on tractor engine type and air inlet placement.
These data presented above can be used for determining the actual service period of the air filter elements to avoid excessive wearing of engine piston-sleeve sliding pairs due to the presence of dust abrasive particles in engine oil lubricating.

Abstract
Improvement and diversification crop production system, followed by progresses of machinery and technology result in enhancements of species compositions, numbers and resistances of various harmful pests causing the crop yields. Therefore, the present study of distributions, density and dynamics of numbers of harmful insects in the replacements in association with recurrent planting way, which plays major role in crop production system is significant not only for economy, but also for the science.
Therefore, focusing on the impacts of fallowing versions on harmful insects, species composition, distribution and density of the insects in each replacements of the crops in such replacement versions as fallow-wheat-wheat and fallow-potato-wheat in 3 replicates at the Research, training and practical center “Nart” in the valley of Boroo river in Bornuur soum of Tov province were investigated by insect secretion trapping, soil sampling and settling cylinders during crop vegetation periods or from May to October, and as a result of the study, greater number of insects of wheat in plowed fallow and number of insects of potato in stitched fallow than other versions is associated with better supply of moisture in these fallows.

Abstract
Result of experiments show the advantage of chemical fallow in soil protection, water saving. Chemical preparation of fallow allows to keep the plant residue on the surface of soil which is protecting from deflection of small particles of soil.
