“…Phosphorus is an integral component of important metabolic and structural compounds in plant cells, acting in cell signaling, transport, and transduction of substrates and chemical energy (Primavesi & Primavesi, 2018;Taiz et al, 2017). Therefore, P availability favors plant growth and development, a fact that can justify the higher yield of oat RDM in the treatments with isolated source and in the mixtures with the presence of TSP, since it is more available to plants, due to its high solubility in water and low residual effect (Dias et al, 2017).…”

The objective of this work was to evaluate the effects of triple superphosphate, magnesium thermophosphate and their mixtures in the agronomic and bromatological characteristics of black and white oats. The experiment was conducted in a 2 × 6 factorial scheme, constituted by the two forages: black and white oats; and two sources of phosphorus (P): triple superphosphate and magnesium thermophosphate, at a dose of 70 kg ha -1 of P 2 O 5 , in the proportions: 0:0, 100:0, 0:100, 50:50, 75:25 and 25:75. The effect of fertilization and P source on the total dry matter of black and white oats (p < 0.05) ranged from 0.21 ± 0.03 to 10.83 ± 0.33 and from 0.14 ± 0.00 to 13.79 ± 0.60 g pot -1 , respectively. Greater forage production was observed in black and white oats fertilized with triple superphosphate (p < 0.05), even when used in a mixture up to 50%. Due to the different responses observed and the variation in the levels of P and crude protein in the forages, it was not possible to determine the effect of the fertilization and the sources of P in these variables. It was verified that black and white oats presented better responses in their productive characteristics when

“…The significant increase in the accumulation of phosphorus in the aerial part of D. nigra seedlings as a function of CRF doses is another desirable point in the production of quality seedlings. The presence of this nutrient in the plant stimulates the growth of the root system and promotes the increase of the soil area to be explored, favoring the acquisition of water and nutrients (DIAS et al, 2017). Factor that can be useful in programs for the recovery of degraded areas and commercial plantations, since the survival, establishment and good productivity of forest stands are greater with the robust root system (GOMES; PAIVA, 2011).…”

For the realization of forest restoration projects, it is essential to produce native seedlings in quantity, also necessary that they present greater vegetative vigor and good nutritional status. In this context, the objective of this work was to analyze the growth and nutrition of phosphorus of Dalbergia nigra seedlings from two sources cultivated with doses of controlled-release fertilizer (CRF). The experimental design was in randomized blocks, arranged in a factorial scheme 2 x 4, referring to lots of two seed sources of D. nigra (Viçosa, MG and Linhares, ES) and four doses of CRF (0, 2, 4 and 8 kg m-3), with four replications and 126 seedlings per plot. At 60, 90 and 120 days after sowing, the seedlings were collected to measure the variables related to growth and nutrition. D. nigra seedlings from Linhares (ES) show better growth and dry matter production. It is recommended to dose 7.46 kg m-3 of controlled-release fertilizer for seedlings from Linhares (ES) and the dose 5.99 kg m-3 for those coming from Viçosa (MG), aiming to maximize the growth of production of seedlings of D. nigra. Increasing doses of controlled-release fertilizer allow greater accumulation of P in shoot shoots of D. nigra.

“…The availability of P in soil can stimulate greater formation of fine roots (effective root system) [16]. Thus, these effective roots can favor absorption of other nutrients that may be below the adequate levels in soil for initial development of eucalyptus plants.…”

The management of fertilizer is an important strategy for better nutrition and productivity of eucalyptus. Therefore, the objective of this research was to evaluate the isolated residual effect (carryover) of N, P and K fertilization on macro- and micronutrients in soil, leaf litter, leaf nutritional diagnosis and initial growth attributes of eucalyptus in a coppice system. Three experiments were carried out in a randomized block design with five replications. Experiment 1: four residual doses of N (0, 70, 105 and 140 kg ha−1) were applied as ammonium nitrate. Experiment 2: four residual doses of P2O5 (0, 40, 70 and 100 kg ha−1) were applied to plantations in furrows using triple superphosphate. Experiment 3: four residual K2O doses (0, 90, 135 and 180 kg ha−1) were applied as potassium chloride. The residual N doses did not influence leaf nutrient contents and initial growth of eucalyptus; however, increasing P residual doses increased soil P and Zn content, litter K content, decreased leaf Mg content, and increased initial growth (height and wood volume of eucalyptus). The residual K doses increased leaf litter K content and leaf Mn and Zn content but decreased leaf litter Ca, B and Fe and leaf Mg content. Residual potassium fertilization did not significantly influence the initial growth of eucalyptus in the Brazilian Cerrado.
