OPPORTUNITIES AND CHALLENGES TO SUSTAINABILITY IN HIDROPONIC SYSTEMS– REVIEW

Hydroponics is a viable solution to obtain intensive agriculture, in terms of producing vegetables and fruits as tasty and nutritious as those produced in classical crops. In the current changing climatic conditions, it can be a viable solution for obtaining high quality food. In addition, the system allows establishment of crops, which do not require the use of soil or manure, but only water that contains various dissolved nutrients. This agricultural cropping technology involves the use of various fertilizers instead of soil for the growth and development of plants. The light needed to develop the plates can come from the sun, or can be produced by renewable energy sources

TECHNICAL CONSIDERATIONS REGARDING TO HARVESTING PATATOES AND CARROTS EQUIPMENT

Potatoes and carrots are two plants of great importance in human life. The two vegetables are grown on increasingly large surfaces, which have led to the need to mechanize their planting, maintenance and harvesting technologies. In the continuation of the material, we will find some types of potato, carrot and root crops for both small surfaces and large and very large surfaces.The harvesting technologies of the two plants are similar, so for the types of potato or carrot picking machines (beet, onions, etc.) and leaves the crop on the furrow, the same type of machine can be used. The diversity of these harvesters is very high from one-row or two-row universal trailed to self-propelled harvesters specialized in harvesting a particular crop, which, through a single pass, can do all of the following: dislocation the harvesting material, sorting, collecting and loading them directly into containers, transport trailers or in their own hoppers with automatic downloading capabilities
