The main factors of production agriculture is labor, capital, natural resources and land, which gradually lose their productive 
quality and require updating. The timely reproduction of productive resources is a prerequisite for sustainable production both in 
agriculture and in the economy as a whole. One of the tools to ensure reproduction of the resource base in favor investment. 
It  should  be  noted  that  economic  theory  is  a  controversial  interpretation  of  the  category  of  "investment"  that  leads  to 
discrepancies between experts. Consider the existing approaches to the definition of investment, are common in the economic 
literature. 
Investments - a relatively new economic  category, as in the planned economy used the concept of "investments", which 
understood the totality of the costs of reproduction of fixed assets, including the cost of their repair. 
However,  investments  -  a  broader  concept  than  capital  investment,  other  than  because  it  includes  investments  in  fixed 
capital investment play in current assets and various financial assets in certain types of intangible assets. Capital expenditure - 
narrower concept, as can be seen merely as a form of investment. 
As an economic category of capital investments considered in the work of a large group of scientists and defined as a system 
of  monetary  relations,  caused  by  the  movement  of  value  advanced  in  order  in  the  long-term  fixed  assets  from  the  date  of 
allocation of funds until their actual compensation. 
Study of theoretical and practical principles of investment devoted to many works of economists. Thus, in modern literature 
is  the  assertion  that  its  content  investment  theory  arose  in  the  sixteenth-seventeenth  century.  -  Socio-economics  of  trading 
investments - mercantilism, which was the subject of research sphere of circulation, the environment "generation of cash money", 
ie the growth of capital. Supporters of the theory of "manufactured" late mercantilism characteristic exaggeration of the role of 
money, which they saw not a single condition of production. 
Fundamentally important for a decision to invest is to determine the "price" rejection of the current consumption. When 
investing in production development investors are not interested in any of the largest result. Capital gains resulting investment 
must be sufficient in order to: 
1. to meet the minimum acceptable from the standpoint of society demands the investor; 
2. recoup the losses from inflation in the period ahead (due to return on the investments); 
3.  compensate  the  investor  for  the  risk  of  a  possible  loss  of  income  from  the  occurrence  of  unforeseen  adverse 
circumstances.  Investments  are  needed  to  ensure  normal  operation  of  the  business  in  the  future,  that  allow:  expansion  of 
production; Prevention of moral and physical depreciation of fixed assets and increase the technical level of production; improve 
the quality of products; implementation of measures for environmental protection; achieve other objectives of the enterprise.
