“…Dans une deuxibme exp6rience en chambres du culture, le soja a t€agi diff6remment au phosphore incorpor6 dans des bandes dispos6es selon des sch6mas diff6rents. Avec un enfouissement d 2,5 cm directement sous les semis, I'augmentation de la matidre sbche produite, de I'absorption du P total et de I'assimilation du P de I'engrais a 6t6 plus accentu6e qu'avec un enfouissement i la meme profondeur que le semis, ou lat6ralementd2,5 cm et 5 Krantz et al (1949) reported slight yield increases for soybean grain on low phosphorus soil when P was applied at24.4 kg P/ha, non-significant increases on high-phosphorus soil with the same level of applied P. Bhangoo and Albritton (1972), in a 3-yr study on the effects of N, P, and K fertilization on soybean, found that P increased yield to a considerably lesser extent than did N or K on a low-P soil.

Bulr-eN, C. W., Sopsr., R. J. eNo Berlsy, L. D. 1983. phosohorus nutrition of soybeans as affected by placement of fertilizer phosphorus. Can. J. Soil Sci.63 199-210. Growth chamber and field experiments were conducted on Southern Manitoba soils, low in available soil phosphorus, to investigate the effects ofvarious placement methods and levels of phosphorus fertilizer on soybean (Glycine max (L.) Merrill'Maple Presto'). It was found that soybean responded well to applied phosphorus on low-P soil in growth chamber studies. In the first growth chamber experiment, P was applied in solution to l\jVa, 50Ta,25Va, l2.5%o and, lVo of the total soil volume. Dry matter yields, total phosphorus uptake and utilization of fertilizer P increased at each level of applied P as the size of the phosphated band was decreased. The results were partly attributed to greater chemical availability of P in the smaller zones of P fertilizer reaction. In a second growth chamber experiment, soybeans responded differently to phosphorus banded in six different locations. Placement of the fertilizer 2.5 cm directly below the seed was more effective in increasing dry matter yield, total phosphorus uptake and fertilizer P utilization than placement 2.5 cm and 5 cm away at the same depth or placement 5 cm below the seed, whether the band was directly below, 2.5 crn away or 5 cm away. Soybean yield responses in the field were greatest with p banded 2.5 cm directly below the seed on tow-P soils. Placement of p 2.5 cm below the seed resulted in grain yieids that were 64Vo and 5OVa higher (at the two sites) than those obtained in control plots. Sidebanding p, 2.5 cm below and 2.5 cm away from the seed at the same level of application, improved grain yields of control plots by 40Vo and 39Va. Seed placement and broadcast applications of P were not as effective in increasing grain yields. Broadcasting P in fall or in spring at rates of up to 52.38 kg P/ha did not result in significantly higher grain yields than those obtained in control plots. Placement ofP in contact with the seed appeared to reduce seedling emergence, resulting in depressed yields when 52.38 kg p/ha were applied.

“…Segundo Hammond et al (1951), a soja apresenta maiores respostas na produção à elevada fertilidade do solo do que a aplicação de grandes quantidades de fertilizantes . Krantz et al (1949) observaram que no início do crescimento do milho houve maior resposta pela adição de superfosfato, enquanto que, para soja, a resposta foi pequena.Hammond e Kirkham (1949) relataram que o crescimento das plantas de milho foi relativamente grande no início de seu desenvolvimento em comparação com a soja. Dessa forma, segundo Hammond et al (1951) o milho teria maior demanda por P no início do seu desenvolvimento do que a soja.…”

RESUMO:Tanto em experimento com milho doce quanto nos experimentos implantados após algodão, milho, arroz e, a própria soja, no norte do Estado de São Paulo, observou-se a capacidade da soja em aproveitar o efeito residual do fósforo (P). Além disso, o nitrogênio (N) fixado biologicamente pela soja pode ser aproveitado pelo milho cultivado em sucessão. Desta maneira, há diminuição no uso dos fertilizantes aplicados, diminuindo os custos nesse sistema de cultivo. Palavras INTRODUÇÃOA realização de diversos experimentos, em diferentes épocas, locais e sistemas de cultivo, atesta o aproveitamento do P residual pela cultura da soja resultante da aplicação da adubação fosfatada nas culturas que antecedem a mesma. Na década de vinte, Thorne (1924), desenvolveu vários experimentos nos principais tipos de solos de Ohio (EUA). Os resultados dos estudos indicaram que em comparação com o milho e trigo, a soja respondeu pobremente à aplicação de fertilizantes.Nelson e Hartwig (1948) obtiveram pequenos aumentos na produção de soja apenas com adição de P na adubação, porém quando além do P, calcário e potássio (K) foram aplicados juntos, obtiveram-se altas produções. Segundo Hammond et al. (1951), a soja apresenta maiores respostas na produção à elevada fertilidade do solo do que a aplicação de grandes quantidades de fertilizantes . Krantz et al. (1949) observaram que no início do crescimento do milho houve maior resposta pela adição de superfosfato, enquanto que, para soja, a resposta foi pequena.Hammond e Kirkham (1949) relataram que o crescimento das plantas de milho foi relativamente grande no início de seu desenvolvimento em comparação com a soja. Dessa forma, segundo Hammond et al. (1951) o milho teria maior demanda por P no início do seu desenvolvimento do que a soja. Assim, o teor de P no solo é importante na determinação da produção

“…The bulk of the fertilizer P was taken up 2 to 3 months after application. Work by Krantz (1949), Welch et al (1949) and Webb (1954) showed recoveries of fertilizer P that exceeded 50% for banded treatments. Data such as these indicate little difficulty in getting the P into the plant tissue.…”
