Zusammenfassung:The invention relates to a process for preparing gelatin-based biostimulators with or without collagen hydrolysate, additivated with macro-, meso- and/or microelements, to be used for stimulating tomato plants. According to the invention, the process consists of the following steps: extracting gelatin from decalcified bovine hide by heating it to a temperature of 75...95°C, decanting and drying it in an oven up to a protein content of 90...95%, possibly additivating with collagen hydrolysate in a ratio of 20...40% by mass relative to the dry matter (d.m.) of the biostimulator, as well as 5...25% macroelements (P and K) and mesoelements (Ca and Mg), or a mixture of mesoelements and a complex of microelements (Cu, Zn, Mo, B) chelated with EDTA, to result in gelatin-based biostimulators with a content of 14.17...23.60% d.m., 1.93...2.81 % total nitrogen, 10.88...15.8% protein and 6.77...7.5 pH units, as a gel or as a diluted product for foliar or radicular application. Invenţia se referă la un procedeu de obţinere a unor biostimulatori pe bază de gelatină cu sau fără hidrolizat de colagen aditivate cu macro, mezo şi/sau microelemente utilizate pentru stimularea plantelor de tomate. Procedeul, conform invenţiei, constă în etapele: extragere a gelatinei din piele de bovină decalcifiată, prin încălzire la temperatura de 75...95 °C, decantare şi uscare la etuvă până la un conţinut de proteină de 90...95%, eventual, aditivare cu hidrolizat de colagen, 20...40% masic raportat la substanţa uscată (s.u.) a biostimulatorului, precum şi 5...25% macro elemente (P şi K) şi mezo elemente (Ca şi Mg), respectiv, amestec de mezo elemente şi complex de microelemente (Cu, Zn, Mo, B) chelatate cu EDTA, rezultând biostimulatori pe bază de gelatină având un conţinut de 14,17...23,60 % s.u., 1,93...2,81 % azot total, 10,88...15,8 % proteină şi 6,77...7,5 unităţi pH, sub formă de gel sau ca produs diluat pentru aplicare foliară sau radiculară.
