“…According to Fidalski et al (2015), the limestone application increases the negative charges in the soil, thus increasing the availability and efficiency of nutrients such as phosphorus. In line with these results, Dias et al (2015) report that the practice of liming associated with the application of phosphate resulted in the best performance of seedlings of Eucalyptus dunnii and Eucalyptus benthamii.…”

Initial Development of Acrocarpus fraxinifolius in Function of Soil Preparation and Phosphate Mineral Fertilization

Acrocarpus fraxinifolius stands out due to its uses in the timber industry and rapid growth. However, information is scarce regarding its fertilization. We aim to understand how soil preparation and phosphorus doses affect A. fraxinifolius initial development. The experimental design used was a randomized block design in a 2 x 5 factorial scheme, consisting of two types of soil tillage (minimum and conventional) and five doses of phosphorus (P) (0, 50, 100, 150, and 200 g of simple superphosphate) with four replications, and plots formed by two plants. The measurement occurs at 30 and 210 days after planting, assessing the height and diameter at the stem height. Initially, the minimum tillage provided had a higher average height and diameter. However, conventional tillage, acidity correction, and fertilization with 108 g of simple superphosphate per plant resulted in Acrocarpus fraxinifolius plants with better growth at 210 days after planting.

“…Reduced P availability in the soil from 18 to 36 MAT was probably caused by P uptake in plants [39][40][41]. ] In addition, reduced P availability observed over time may be part of the P deriving from fertilizer forms, an inner sphere complex with functional groups of inorganic particles, and it reduces the P amounts extracted with the aid of simple extractors, such as Mehlich-1 [30,42,43].…”

Phosphorus (P) availability in subtropical soils does not often meet the nutritional demand of native tree species such as the ipê-roxo tree (Handroanthus heptaphyllus); therefore, it is necessary to supply P at planting. However, the impact of P on root system growth remains unknown. The aim of the current study was to investigate the effect of P application on root morphology of H. heptaphyllus plants over a 36-month period in a subtropical climate region. During the experiment, the plants subjected to fertilization with 40 kg P ha−1 were compared to untreated control. Plant roots were scanned through minirhizotron system 18 and 36 months after transplant (MAT), and generated images were used to determine total root length, mean root diameter and total root volume. Plant height and leaf P concentrations were also evaluated. Phosphorus application enhanced root and whole plant growth with a more evident effect at 36 MAT, when soil P availability decreased. The results give important information on the cultivation of H. heptaphyllus plants in soils presenting low P availability.

“…De modo geral, o eucalipto cresce rápido e responde a variações na fertilidade do solo (Mendes et al, 2013;Dias et al;. A adubação do eucalipto é realizada empregando-se geralmente fertilizantes minerais e, boa parte dos fertilizantes, é aplicada no momento do plantio (adubação de base), de modo a proporcionar o arranque das mudas no campo (Barros et al, 2000;Gonçalves, 2005).…”

RESUMONeste trabalho, foi avaliada a viabilidade do uso de composto de lodo de esgoto, proveniente de estação de tratamento de esgoto, como fertilizante alternativo para o cultivo inicial de eucalipto. O experimento foi realizado em casa de vegetação no CCA -UFSCar, Araras, SP. Os cultivos ocorreram em vasos de 11 L durante 75 dias. O delineamento experimental foi inteiramente ao acaso, com cinco tratamentos e sete repetições. Os tratamentos adotados foram constituídos por uma testemunha, três tratamentos com composto de lodo de esgoto (25%, 50% e 75% do volume do vaso) e um tratamento com fertilizante mineral convencional, todos em solo arenoso. Ao final do experimento, a taxa de crescimento relativo (TCR) e a massa seca das plantas foram medidas e submetidas à análise de variância seguida pelo teste de Tukey a 5% de probabilidade. A TCR foi maior nos tratamentos com fertilização do que na testemunha, mas não diferiu entre a fertilização mineral e as doses de fertilização orgânica. A massa seca das plantas foi maior no tratamento com 50% do volume do vaso com fertilizante orgânico (p<0,01). Assim, o composto de lodo de esgoto se mostrou com potencial para substituir fertilizantes minerais convencionais no cultivo inicial de eucalipto.Palavras-chave: composto orgânico, fertilizante, nutrição vegetal,.orgânico classe D, sustentabilidade. Sewage sludge compost for initial cultivation of eucalyptus ABSTRACTThis study evaluated the feasibility of sewage sludge compost obtained from a sewage treatment plant as an alternative "Class D" organic fertilizer for the initial cultivation eucalyptus. The experiment was conducted in a greenhouse at CCA -UFSCar, Araras, SP. Cultivation occurred in 11 L pots for 75 days. We adopted a completely randomized design, with five treatments and seven repetitions. The tests considered a control treatment with no fertilization, three treatments with sewage sludge compost addition (25%, 50%, and 75% of the pot volume) and a treatment with conventional mineral fertilizers, all in sandy soil. At the end of the experiment, plant relative growth rate and dry mass were evaluated and submitted to analysis of variance, followed by a Tukey test at 5% probability. Treatments with
