INFLUENCE OF CONSERVATIVE SOIL WORK IN MAIZE: FUEL CONSUMPTION PUBLISHEDTRUȚAN Ilie, DUMA-COPCEA Anișoara, MIHUȚ Casiana, SCEDEI Daniela None email@example.com
Soil “conservative work” is a generic expression, which refers to a multitude of methods of work, from direct sowing to the aerating and mobilising the entire soil profile, excluding the turning of furrows and the burning of stubble, allowing the maintenance of plant debris on the surface of the soil or close to the surface of the soil and/or the preserving the soil to reduce erosion and improve soil-water relation. The transition from conventional soil to conservative systems was not simple and it gave rise to a multitude of questions to which relevant, scientifically well-founded rhetoric was required, some of which were obtained through fundamental and applicative research carried out under specific local conditions. The large-area implementation of conservative soil systems is not yet nearly resolved even in countries with very high technological potential and solid specialized knowledge. Conservative agriculture aims to increase agricultural production by optimising the use of agricultural resources contributing to reducing widespread land degradation through integrated management of available soil, water and biological resources combined with extreme raw materials. Soil works primarily result in changes in physical attributes that further influence the chemical and biological properties of the soil. It should be pointed out that the technique and time (period) during which soil works are carried out are subject to plant requirements, the purpose for which it is cultivated, as well as to ecological, climate, soil and relief conditions. The unconventional soil work system includes ways of superficial soil processing, namely: heavy disc harrowing, combined rotary grape work, work with the cultivator and the work with the chisel. Unlike the classical system, only soil works are different, the other technological elements (fertilization, herbicide) remain the same. Vegetable debris that remains on the ground at a share of 15-30% being incorporated into the soil according to the variant used. In 2019, there was a consumption of 105.00 l/ha for the control variant, and for variants with minimum tillage, values between 91.00-99.00 l/ha were recorded.
