Mixed plantations of Eucalyptus and nitrogen (N)-fixing tree legumes (NFT) benefit the cycling of nutrients in Eucalyptus stands due to the increased absorption of phosphorus (P) and greater input of organic matter. The objective was to quantify the different fractions of P in terms of lability and its correlation with the fractions of organic matter, to clarify the effect of mixed plantations on the modifications of different P and carbon (C) fractions in Planossolo Háplico (Planosol). Monospecific stands of Eucalyptus urograndis (0A:100E) and Acacia mangium (100A:0E) were established in addition to mixed plantations: one presenting 50% planting density of each species (50A:50E) and the other with double planting density (100A:100E). The soil samples were collected at depths of 0-5 cm and 5-10 cm and the total organic carbon, particle size fractions, labile carbon, total phosphorus, labile organic and inorganic phosphorus, moderately labile and moderately resistant and residual phosphorus were determined. It was observed in the mixed plantations 50A:50E, the highest values of total phosphorus and concentration of organic P (56.84%), highlighting the fractions of greater lability in addition to presenting a lower C:Po ratio (187.28) and higher labile carbon concentration at both depths. Mixed plantations 50A:50E promote an increase in the organic P compartment in the soil, mostly in fractions of greater lability. Monospecific stands of A. mangium and E. urograndis seem to have P cycling limited by the supply of P and N, respectively. Labile carbon, presents itself as an important indicator of soil quality.

Abstract: In this study, we evaluated the effectiveness of using estrogen-induced prolonged luteal function followed by prostaglandin F2 alpha (PGF2α) treatment to synchronize estrus in gilts. On day12 of the estrus cycle (D0 = first day of standing estrus), 52 gilts were assigned at random to two experimental groups: non-treated gilts (CON, n = 22), serving as controls, and prolonged luteal function group (CYP, n = 30), receiving a single treatment with 10 mg of estradiol cypionate intramuscularly Starting on day 12, blood samples were collected for estradiol and progesterone assays. Estrus detection started on day 17. Gilts from the CON group were inseminated at the onset of natural estrus. On day 28 CYP gilts were treated with PGF2α to induce luteolysis and inseminated at the onset of estrus. Gilts were slaughtered 5 d after the last insemination. A single treatment with estradiol cypionate prolonged luteal function in 90% of treated gilts. The duration of the estrous cycle was longer (p < 0.0001) for CYP gilts compared to CON gilts. CYP gilts showed synchronized estrus 3.96 ± 0.19 d after induction of luteolysis. The conception rate was similar (p = 0.10) for CON and CYP gilts. No difference was observed in the embryo recovery rate (p = 0.18) and total number of embryos per female (p = 0.06). The percentage of unfertilized oocytes, fragmented embryos and viable embryos was similar among females from CON and CYP groups (p > 0.05). The treatment of gilts with a single application of 10 mg of estradiol cypionate on day 12 of the estrous cycle was effective in prolonging luteal function and treatment with PGF2α resulted in synchronized estrus. Additionally, the synchronization protocol had no deleterious effect on fertility and embryonic development.
