Resumo: | A greenhouse experiment was carried out with surface samples from States of São Paulo, Minas Gerais and Goiás (Brazil). Carbon contents varied from 0.5 to 3.03%, sulphur from 0.0104 to 0.0310% and clay from 8 to 60%. Corn (Zea mays L.) was grown in two successive crops, with three rates of gypsum (0, 20 and 40 ppm S), previously incubated in absence and presence of lime. Soil analyses were made before and after the first cropping. Plant material was analysed after each harvest of the top. By using data from both soil and plant analyses multiple regression equations were calculated. Close relationships were found in the following cases: sandy soils: dry matter production as a function of total S and N/S ratio in the plants and extractable S-SO4= in the soil; accumulation of S in the plants as related to the same variables and soil pH; clayey soils: dry matter as a function of total S and N/S ratio in plants and pH, Ca++, Mg++, H+ + Al+++ and carbon in soils; accumulation of S in the plants as against their N/S and P/S ratios, and calcium phosphate extractable S-SO4=, pH, H+ + Al+++ and carbon in the soils. In sandy soils, sulphur availability depends only on extractable sulphur contents, being unaffected by liming in clayey soils, it is influenced by liming (pH and CTC) and carbon contents. Independently of texture and carbon content of the soils, dry matter yield and sulphur uptake show inverse relationships with corn leaf tissue N/S and P/S ratios. KEY-WORDS: Sulphur; soil-plant; multiple regression; joint analysis. |

Conduziu-se um experimento em casa de vegetação em amostras superficiais de 12 solos provenientes dos Estados de São Paulo, Minas Gerais e Goiás (Brasil), com teores de carbono variando entre 0,5 e 3,03%, de enxofre total entre 0,0104 e 0,0319% e de argila entre 8 e 60%. Os solos foram submetidos a dois cultivos sucessivos com milho (Zea mays L.), com 3 doses de gesso (0, 20 e 40 ppm de S), previamente incubados na presença e ausência de calagem. Fizeram-se análises das amostras de solos antes e após o primeiro cultivo e da parte aérea das plantas dos dois cultivos. Com as análises de solos e plantas, por meio de regressão múltipla, encontraram-se relações estreitas nos seguintes casos: solos arenosos: produção de matéria seca com o teor de S total e da relação N/S na parte aérea do milho e do S-SO4= extraível por fosfato de cálcio; absorção de S pela planta com as mesmas variáveis e mais pH do solo; solos argilosos: produção de matéria seca com o S total e da razão N/S nas plantas e pH, Ca++, Mg++, H+ + Al+++ e carbono dos solos; absorção de enxofre com as razões N/S e P/S nas plantas, S-SO4= extraível por fosfato de cálcio, pH, Ca++, Mg++, H+ + Al+++ e carbono dos solos. Nos solos arenosos, a disponibilidade de enxofre é dependente apenas do enxofre extraível, não sendo afetada pela calagem; nos solos argilosos, é afetada pela calagem (pH e CTC) e teores de carbono. Independentemente da textura e do carbono dos solos, a produção de matéria seca e absorção de enxofre apresentam relação inversa com as razões N/S e P/S do tecido foliar do milho.
