CHEMICAL PROPERTIES AND PHYSICAL FRACTIONS OF ORGANIC MATTER IN OXISOLS UNDER INTEGRATED AGRICULTURAL PRODUCTION SYSTEMS 196
de Moraes Rego, Carlos Augusto Rocha; Oliveira, Paulo Sérgio Rabello de; Piano, Jeferson Tiago; Egewarth, Jonas Francisco; Egewarth, Vanessa Aline; López de Herrera, Juan; Gonçalves Junior, Affonso Celso.
The main cause of decreased soil fertility and soil organic matter content is intensive crop farming with inadequate management. This study aimed to evaluate soil chemical properties, total organic carbon content, physical granulometric fractions (particulate organic carbon and mineral-associated organic carbon), carbon stocks, and carbon management indices of oxisols in different integrated agricultural production systems (IAPSs) with reference to values in a haymaking area and native forest. The experiments were performed using completely randomized design, considering nine differently managed areas, including seven IAPSs and two reference areas (haymaking area and native forest); four soil samples from the 0.00-0.05, 0.05-0.10, and 0.10-0.20 m layers...

INITIAL DEVELOPMENT OF COFFEE SEEDLINGS IN THE PRESENCE OF PLANT EXTRACTS 196
Costa, Bruna Penha; Duarte Júnior, José Barbosa; Rinaldi, Luanna Karoline; de Moraes Rego, Carlos Augusto Rocha; Stangarlin, José Renato.
The coffee plant can grow together with different plants, but the presence of allelochemicals can affect the crop post-planting. This study aimed to evaluate the early growth of coffee seedlings following treatment with plant extracts from different botanical families. The experimental design used randomized blocks with four trials, in a 7 × 2 factorial scheme; the first factor consisted of aqueous extracts from six species: canola, crotalaria, brachiaria, sunflower, wheat, and lupine; water was used as the control. The second factor comprised of different botanical parts of the aforementioned six species of plant. The extracts were diluted to 5% concentration and were applied at a dose of 20 mL per plant. The agronomic variables analyzed were plant height...
