Modern agriculture requires the use of modern technology, with new
technical and technological solutions. Basic agro-technical operation in phase of
establishing orchards and vineyards that requires large amounts of energy is plowing, for
its specificity called rigoling. Trenching phase consumes greatest portion of energy int he processing and preparation of land in general and especially for the establishment of
cultural agricultural fruit-grape production. There are more operational technologies, and
this paper analyses classical technology, and combined technology using rigoler and
plowing tools for soil cultivation.
When classic technologies are applied, soil is cut and sectioned, moved and crushed,
thus creating loose soil layer. The depth of processed soil is different for different fruitgrape
crops, depending on the needs of the root system, as penetration depth and the
breadth of development, ranging between 60 and 100 cm.
Such technology moves active soil layer to the inactive bottom of the furrow, while
inactive soil layer is removed to the surface. This technology has to be defined for
different soil types.
Combined technical-technological solution using a rigoler with built-in plow
enables the achievement of working depth required by the root system, but the inactive
soil layer is not moved to the surface of the plowed soil. The lower topsoil layer is only
shaken and broken. Work technology combining rigoler and plow in one pass, can
significantly increase technological production, while saving significant amounts of
energy. This technology should be applied to avoid unnecessary expenditure of energy. U radu su prikazani rezultati ostvarenih vučnih otpora pri rigolovanju
zemljišta sa plugom rigolerom na dubini od 60 cm, 70 cm, 80 cm i 90 cm, kao i vučni
otpori rigolera sa dodatnim radnim organom u obliku dleta. Dodatkom dleta, dubina
rigolovanja po varijantama rada, povećana je za 10 cm, 15 cm i 20 cm.
Dobijeni rezultati pokazuju da na povećanim dubinama rigolovanja, specifičan otpor
zemljišta ima nepromenjenu vrednost kao i pri samom rigolovanju. Ovo se postiže time
što je odnos povećane dubine rigolovanja veći od povećanog vučnog otpora sa dodatkom
dleta. Ekonomičnost upotrebe dleta je do 70 cm rigolovanja i 20 cm dubine rada dleta.
Iznad 70 cm rigolovanja primena dleta se ekonomski smanjuje, jer se na toj dubini
ispunjava agrotehnički zahtev.
