Phosphorus behavior on an Oxisol fertilized by phosphate alkaline biosolid and cultivated with common bean R. Bras. Eng. Agríc. Ambiental, v.16, n.12, p.1261-1268, 2012. A B ST R A C T This study aimed to evaluate the extractable phosphorus Mehlich-1 in a distrophic Red-Yellow Latosol (Oxisol) which received alkaline sewage sludge (alkaline biosolid) along with 0, 0.436, 0.872 and 1.745 dag kg -1 of P from three different sources and cultivated with common bean (Phaseolus vulgaris cv. IPR Uirapuru) in greenhouse. It also aimed to quantify the phosphorus uptake by the plant, plant production and the relative agronomic effectiveness index. For the establishment of the treatment the recommended dose was 45.85 kg ha -1 of P from the treatments, except the control (0 dag kg -1 of P). This dose was calculated for 2.5 kg of this Oxisol from Contenda, Paraná State, Brazil, contained in recepients of 3 dm 3 with 6 cultivated bean plants (cv. IPR Uirapuru). Phosphorus added in alkaline biosolid increased the extractable phosphorus (Mehlich-1) in soil and phosphorus accumulated in plants as well as the grain and total dry mass production of bean plants. The best level of phosphorus added to alkaline biosolid was 0.436 dag kg -1 of P from the partially acidulated phosphate rock Alvorada and single superphosphate. Key words: phosphorus, dose, grains, dry mass, Phaseolus vulgarisComportamento do fósforo em Latossolo fertilizado com biossólido alcalinizado fosfatado e cultivado com feijoeiro R ESU M O Propôs-se, com este trabalho, avaliar o fósforo extraível Mehlich-1 em um Latossolo Vermelho-Amarelo Distrófico típico, ácido, que recebeu lodo de esgoto alcalinizado (biossólido alcalinizado) adicionado com 0, 0,436, 0,872 e 1,745 dag kg -1 de P proveniente de três diferentes fontes e cultivado com feijoeiro (Phaseolus vulgaris cv. IPR Uirapuru) em casa de vegetação. Objetivou-se, também, quantificar o fósforo acumulado pelas plantas, a produção das plantas e o índice de eficiência agronômica relativa. Para o estabelecimento de tratamentos a dose recomendada foi de 45,85 kg ha -1 de P a partir dos tratamentos, exceto da testemunha (0 dag kg -1 de P). Esta dose de fósforo foi calculada para 2,5 kg deste Latossolo de Contenda, Paraná, contidos em vasos de 3 dm 3 cultivados com 6 plantas de feijoeiro (cv. IPR Uirapuru). O fósforo adicionado em biossólido alcalinizado aumentou o fósforo extraível Mehlich-1 do solo, a acumulação de fósforo pelas plantas bem como a produção de grãos e a massa seca total das plantas de feijoeiro. O melhor nível de fósforo adicionado ao biossólido alcalinizado foi de 0,436 dag kg -1 de P proveniente de fosfato natural parcialmente acidulado Alvorada e superfosfato simples.

“…providing P for maize plants, being less than 30% as effective as TSP applied at the same rate (using a vertical comparison of Mnkeni et al (2000) at 20 kg P ha -1 ). Substitution ratio or Horizontal comparison (using the equation of Chien et al 1990) suggests that by the time maize had reached silking stage, FYM and Tithonia were only 15 and 30% as effective as TSP.…”

12Phosphorus (P) deficiency is a major constraint for crop production in many parts of the 13 world including Myanmar and field research into management of P fertilisers and P 14 responsiveness of crops on infertile soils has been limited. The purpose of this study is 15 to determine maize yield response to different forms of P fertilisers on an acidic (pH 16 4.9) P deficient Yellow Earth (Acrisol) in Southern Shan State, Myanmar and to 17 establish relationship between soil Olsen-P test values (0.5 M sodium bicarbonate 18 extracted P) and maize yield. Field experiments were conducted during two cropping 19 seasons. There were 15 treatments in total: P was applied at 7 rates of a soluble P 20 fertiliser as Triple superphosphate (TSP) (0 to 120 kg P ha -1 ) to establish a P response 21 curve; one rate of a partially soluble P fertiliser (Chinese partially acidulated phosphate 22 rock, CPAPR) and two organic P fertilisers (farmyard manure (FYM) In Year 1, applications of TSP at 40-60 kg P ha -1 produced near maximum grain yields, 4 whereas in Year 2 this could be achieved with a reapplication of 20-30 kg P ha -1 on top 5 of the residual value of the Year 1 application. In both years, CPAPR, TSP and T. 6 diversifolia significantly increased maize grain yield, but FYM failed to increase grain 7 yield. In Year 1, CPAPR and TSP effects on grain yield were higher than that of T. 8 diversifolia but in Year 2 the effects were same for all these three treatments. The 9 combination of FYM (20 kg P ha -1 ) or T. diversifolia (20 kg P ha -1 ) with TSP (20 kg P 10 ha -1 ) or CPAPR (20 kg P ha -1 ) was as effective as TSP (40 kg P ha -1 ) applied at an 11 equivalent P rate for optimum grain yields of maize in both years. The combined data 12 from the two years experiment suggests that 90% of maximum maize grain yields can 13 be obtained by raising the Olsen-P to 30-35 mg P kg -1 soil at the silking stage of growth. 14 Olsen-P for the treatments at silking in Year 1 was: Control < FYM, T. diversifolia < 15 TSP, CPAPR and in Year 2 was: Control < FYM < T. diversifolia < TSP, CPAPR. The 16 results showed that for a long-term approach, repeated annual applications of T. 17 diversifolia can be considered as a potential P source for improving soil P status in the 18 Yellow Earth. 19 20

Ten P fertilizers were collected (commercial fertilizers) or synthesized (experimental sources) in order to obtain single superphosphates varying in water and citrate solubility. A standard source of P was also produced by crystallization of the water-soluble fraction of a triple superphosphate. Eleven P sources were band applied to a medium textured Xanthic Hapludox, in Bahia, Brazil (low content of resin-extractable P) at a rate of 80 kg ha -1 of NAC + H 2 O (neutral ammonium citrate plus water) soluble P 2 O 5 , with soybean as the crop which was grown to maturity. A check plot (control) was included in the study. Three of the P sources [single superphosphate produced from Araxa phosphate rock (PR), low-grade single superphosphate produced from Lagamar PR and the standard source of P] were also applied at rates to provide 40 and 120 kg ha -1 of NAC + H 2 O soluble P 2 O 5 . Yield of soybean was evaluated by analysis of variance with mean comparison performed utilizing LSD lines, considering the P sources applied at a rate of 80 kg ha -1 of P 2 O 5 + control. Regression procedures were used to study the relation between yield of soybean and rates of P 2 O 5 . The fertilizers tested performed equally well as a source of P for soybean. The level of water-soluble P did not influence fertilizer performance. Key words: acidulated phosphates, available P, phosphorus sources, water-insoluble P AVALIAÇÃO AGRONÔMICA DO FÓSFORO SOLÚVEL EM ÁGUA OU CITRATO DE FOSFATOS DE ROCHA ACIDULADOS PARA A SOJARESUMO: Dez fontes de P foram coletadas em unidades revendedoras de fertilizantes comerciais ou produzidas em laboratório de tal forma a obter superfosfatos simples com variabilidade em água e citrato neutro de amônio + água (CNA + H 2 O). Utilizou-se como fonte padrão de fósforo a fração solubilizada, filtrada e cristalizada de um superfosfato triplo. As onze fontes de P foram aplicadas nas linhas de semeadura de soja de um Xanthic Hapludox textura média, localizado no Município de Barreiras, Bahia (baixo teor de fósforo resina) na dose de 80 kg ha -1 de P 2 O 5 solúvel em CNA + H 2 O. Três das fontes (superfosfatos simples produzido a partir da rocha fosfática de Araxá e Lagamar e a fonte padrão) foram aplicadas também em doses de 40 e 120 kg ha -1 e uma parcela testemunha, sem P, adicionada ao experimento. A produtividade da soja foi avaliada por meio de análise de variância e comparação de médias, considerando-se as fontes de P aplicadas na dose de 80 kg ha -1 P 2 O 5 + parcela testemunha. Regressões foram utilizadas para estudar a relação entre a produtividade de soja e as doses de P 2 O 5 . Os fertilizantes tiveram igual comportamento como fonte de P às plantas de soja. O teor de P 2 O 5 solúvel em água não influenciou o comportamento dos fertilizantes. Palavras-chave: fosfatos acidulados, P disponível, fontes de fósforo, fósforo insolúvel em água
