Abstract

A szántóföldi tartamkísérletek az agrokémiai, növénytermesztési kutatások speciális szabadföldi laboratóriumai. A múlt század közepén elindított korszerű hazai tartamkísérleteknek köszönhetően olyan egyedülálló adatbázis jött létre, amely napjainkban megbízható hátteret ad a tudományos alapokra helyezett, a környezetet nem terhelő, precíziós növénytáplálás megvalósításához. Hazai trágyázási és növénytermesztési tartamkísérletek publikált eredményeinek rendszerezésével és feldolgozásával három évtizede kezdődött meg az a szoftverfejlesztés, amelyet Németh Tamás akadémikus mentorálásával ma ProPlanta szaktanácsadási rendszerként ismerünk. A továbbra is folyamatos fejlesztések eredményeit a legrangosabb innovációs díjakon túl mindenekelőtt a gyakorlati alkalmazás bővülése igazolja. | Field trials are open-air laboratories in which the effects of various treatments on the soil and the crops are studied over long periods of time, from decades to centuries. The first modern long-term field experiments were set up in Hungary from the middle of the last century, initially investigating the effects of fertilisation, which was later combined with other factors: planting date, plant density, variety, etc. Based on the correlations found in the database of half a century of long-term field fertilisation experiments in Hungary, a new, environmentally friendly fertilisation advisory system was developed three decades ago at the Research Institute for Soil Science and Agricultural Chemistry (Budapest) and the Agricultural Research Institute (Martonvásár) of the Hungarian Academy of Sciences (now institutes of the HUN-REN Centre for Agricultural Research) under the leadership of Professor Tamás Németh. During the development of the new system and its software, more emphasis was put on the specific nutrient requirements of plant species, the reduction of soil nutrient loads and the variation of specific nutrient requirements depending on the yield. The fertilisation advisory system, now known as ProPlanta, provides farmers with 4 levels of advices depending on the planned intensity of cultivation. Today, ProPlanta can be used to produce expert advice for 149 crop species (82 arable crops, 45 field vegetable crops, 22 fruit species) and vines. Environment protection considerations are also taken into account in preparing recommendations that are always adjusted to the legislations in force and are in line with the requirements of precision crop management. Among the users of the ProPlanta system we can find some of the most important players of the Hungarian agriculture. The total area that was fertilised according to ProPlanta recommendations is now close to one and a half million hectares, while the savings for farmers from the more rational use of fertilisers proposed by the system exceed HUF 3 billion. Even on the basis of conservative estimates, nitrate and phosphate loads to our soils have also been significantly reduced by 2,500 tonnes and 15,000 tonnes, respectively. Smart fertilisation reduces nitrate pollution of groundwater used for drinking water and the risk of phosphorus pollution of surface waters. ProPlanta is an excellent example of how the results of decades of research can innovatively support resource efficient and smart agriculture.
