Dynamic of Phosphorus Fractions in Typic Quartzipsamment Soil Cropped With Bean.
ALOVISI, A. M. T.; SERRA, A. P.; ALOVISI, A. A.; TOKURA, L. K.; LOURENTE, E. R. P.; CARNEIRO, L. F.; SILVA, M. A. C. da; DAVIDE, L. M. C.; SANTOS, S. C.Phosphorus is the most limited nutrient in Brazilian soils for plant growth, resulted of low availability and poor P content in bedrock. The aim of the study was to evaluate the dynamic of P fractions in a sand soil typical Quartzipsamment cropped with common bean under the effects of P and Si-fertilizer rates. The research was carried out in a soil with sand texture and clay mineralogy constituted mainly by ka...
Phosphorus Fractions and Their Transformations in Entisol.
ALOVISI, A. M. T.; ALOVISI, A. A.; SERRA, A. P.; TOKURA, L. K.; DAVIDE, L. M. C.; LOURENTE, E. R. P.; SILVA, R. S. da; TOKURA, W. I.; SOUZA, D. A. deThe availability of phosphorus in the soil is a factor that directly interferes with its absorption by plants. This availability can be influenced by the texture, dose of the phosphate fertilizer and the time of contact with the soil. This study aimed to quantify the organic and inorganic fractions of P accumulated in a sandy soil receiving doses of phosphorus, incubated and grown with rice. The experimental de...
The effects of crop rotation systems on maize agronomic traits under no-tillage...
SOUZA, L. C. F. de; FREITAS, M. E.; LOURENTE, E. R. P.; SERRA, A. P.; RECH, J.; FROTA, F.; LOUREIRO, G. E. S.The purpose of this research was to evaluate the crop rotations effects on agronomic traits of maize cultivated in spring-summer in optimal (OCS) and dry cropping seasons (DCS). The experimental design was set up in a randomized complete block and the treatments were arranged in a factorial (8 x 2), consisting of 8 crop rotation systems and two cropping seasons (OCS and DCS), with four replications. The followi...
Agricultural management systems affect on physical, chemical and microbial soil...
LOURENTE, E. R. P.; SILVA, E. F. da; MERCANTE, F. M.; SERRA, A. P.; PEIXOTO, P. P. P.; FERREIRA, R. C. F.; ENSINAS, S. C.; NETO NETO, A. L.The purpose of this research was to assess the effects of replacement of native ?Cerrado? vegetation (NV) into croplands on soil chemical, physical and microbial properties. This research was carried out on a farm under Rhodic Hapludox soil with different types of agricultural managements systems, and it was used a NV to compare the systems. The experimental design was set up in completely randomized with five ...

ALOVISI, A. M. T.; FURTINI NETO, A. E.; SERRA, A. P.; ALOVISI, A. A.; TOKURA, L. K.; LOURENTE, E. R. P.; SILVA, R. S. da; SILVA, C. F. B. daThe purpose of this research was to evaluate the effects of P and Si fertilizer rates in dynamic of P fractions in clay soil under greenhouse. The research was carried out in a Dystroferric Red Latosol of a very loamy texture from Lavras city, Minas Gerais State, Brazil. The experimental design was entirely randomized, arranged in 4 × 3 factorial design, with four repetitions. The treatments included four inorg...
Soybean agronomic performance in narrow and wide row spacing associated with NP...
ROSA, C. B. C. J.; MARCHETTI, M. E.; SERRA, A. P.; SOUZA, L. C. F. de; ENSINAS, S. C.; SILVA, E. F. da; LOURENTE, E. R. P.; DUPAS, E.The purpose of this research was to evaluate soybean agronomic traits performance under row spacing associated with NPK fertilizer. The experimental design was set up in a randomized complete block and the treatments were arranged with factorial concept, consisting of four NPK (02-20-18%) fertilizer rates (0; 200; 400 and 600 kg ha-1) and five row spacing (0.35; 0.45; 0.50; 0.60 and 0.70 m), with three replicat...
Cover crops affect on soil organic matter fractions under no till system.
ENSINAS, S. C.; SERRA, A. P.; MARCHETTI, M. E.; SILVA, E. F. da; PRADO, E. A. F. do; LOURENTE, E. R. P.; ALTOMAR, P. H.; POTRICH, D. C.; MARTINEZ, M. A.The purpose of this research was to identify the soil organic matter (SOM) fractions changes in a crop rotation system under no-till system (NTS). This research was carried out from October 2010 to February 2014 in a Rhodic Hapludox. The experiment was set up in completely randomized blocks in a factorial design with eight cover crops and three soil depths (0-5, 5-10 and 10-20 cm) with four repetitions. Cover c...
