Autores: Robledo Santoyo, Edmundo.
Como subproducto del tratamiento de las aguas residuales de la ciudad de Aguascalientes, Ags., en la Planta de Tratamiento “El Niágara”, se generan diariamente de 150 a 170 m3 de biosólidos. Estos materiales son aplicados a suelos agrícolas de áreas cercanas a la planta, sin regulación alguna, por lo que se han obtenido buenos resultados o causado quemaduras en plántulas o endurecimiento de suelos. El objetivo de este proyecto fue generar estrategias para la disposición y aprovechamiento de los biosólidos para mejorar suelos agrícolas y la calidad y rendimiento de los cultivos, sin perjuicio para el ambiente. Para determinar el efecto de los biosólidos sobre suelos y plantas, se colectaron muestras de los biosólidos y se tomaron muestras de tres tipos de...

ABSTRACT: Soil acidity and soil phosphorus deficiency may be constraints factors to cassava production in cerrado soils. Therefore, the cultivation of cassava requires the adequate management of soil acidity and fertility, by the using of the appropriate combination of lime and phosphate fertilizer. Field experiments were carried out combining lime and phosphate fertilizer levels and cultivated with IAPAR 19 cassava variety. The best response in productivity was observed at the level of 200kg ha(-1) of P2O5 and 25% of soil base saturation, which corresponds to the level of 2t ha(1-) of lime for the present soils. Significant interactions were observed between lime and phosphate fertilizer, the best combination being the using of lime to increase the soil...

Uso de gesso, calcário e adubos para pastagens no cerrado.
Provedor de dados: 14
Autores: SOUSA, D. M. G. de; VILELA, L.; LOBATO, E.; SOARES, W. V.
A pecuária no Cerrado baseou-se, por muitos anos, na exploração de pastagens nativas. Nas três últimas décadas, o crescimento acentuado do rebanho bovino na região e o incremento de até cinco vezes na capacidade de suporte das pastagens deveu-se ao aumento da área com grandes gramíneas forrageiras, provenientes do continente africano, especialmente as do gênero Brachiaria e o Andropogon gayanus cv. Planaltina. Estabelecidas sem adubação ou com o efeito residual de modestas adubações da cultura do arroz, sem adubação de manutenção e submetidas a manejo inadequado, extensas áreas dessas pastagens encontram-se em variados graus de degradação. A ausência de adubação de reposição durante décadas de extração dos nutrientes tornou necessária a recuperação dessas...

ABSTRACT: The sweet passion fruits is a native species of Brazil. It is very well adapted to tropical regions, and can be found growing in wild conditions or cultivated by small farmers in many regions. It is consumed mainly as a fresh fruit, splitting with a knife in two parts and using a spoon to collect the pulp with the seeds. The concentrated juice, easily extracted from the pulp, can be used to make juice, ice-cream and deserts. Many small farmers grow sweet passion fruit as an ornamental plant, particularly because of the beauty flowers and colored fruits. In additon it is considered as a medicinal species to treat stress, anxiety and sleeplessness. The ofter of fresh sweet passion fruit in most fruit and grocery stores is still very limited, and...

Efeito residual do calcário para o milho sob plantio direto e convencional em solo de Cerrado.
Provedor de dados: 14
Autores: MIRANDA, L. N. de; MIRANDA, J. C. C. de.
ABSTRACT: The Cerrado soils are acid with toxic levels of aluminum, being necessary to use lime to overcome these conditions to grow crops. The residual effect of lime in a Red Latosol were evaluated for corn at the 5th and 6th crop, under conventional tillage (disk plowing and harrowing) and no-tillage planting systems. Lime at different levels was previously applied for the first crop, with and without incorporation into the soil. The results showed a significant increase in corn grain production due to the residual effects of lime levels, either incorporated, surface applied with no incorporation, or a mixing of both methods. After six years of cropping, the surface applied lime with no incorporation changed the soil conditions mainly at the 0 cm - 10...

Autores: MIRANDA, L. N. de; MIRANDA, J. C. C. de.
ABSTRACT: The Cerrado soils are acid and deficient in calcium and magnesium, which limit crop growth. Also, there is aluminum toxicity for plant roots being necessary using lime to overcome these conditions. The effects of lime levels and methods of lime application in a Red Latosol, were evaluated. A soybean and corn crop rotation were settled, under conventional (disk plowing and harrowing) and no-tillage planting systems, for four years. Cover crops were planted in the dry season, mucuna cultivated after soybean and millet after corn. One lime treatment was included without cover crop under the conventional system. The occurrence of a dry spell period reduced the soybean yield in the first crop, but yield increases were observed due to lime application,...

Powders of kudzu, velvetbean, and pine bark added to soil increase microbial population and reduce Southern blight of soybean
Provedor de dados: 102
Autores: Blum,Luiz E. B.; Rodríguez-Kábana,Rodrigo.
Southern blight (Sclerotium rolfsii) of soybean (Glycine max) is an important disease throughout the world. Some soil amendments can reduce disease levels by improving soil microbial activity. The main goals of this study were to investigate the effects of soil amendments such as dried powders of kudzu (Pueraria lobata), velvetbean (Mucuna deeringiana), and pine bark (Pinus taeda), on soil microbial population and disease caused by S. rolfsii on soybean. Pine bark, velvetbean (mucuna) and kudzu (25 g kg-1) added to soil were effective in reducing disease incidence [non-amended (NA) ~ 39%; amended (A) ~ 2 to 11%)]. Bacillus megaterium was the bacteria most frequently isolated in soils with velvetbean or kudzu (NA ~ log 5.7 CFU g-1 of dried soil; A ~ log...

Provedor de dados: 65
Autores: Shen,Yuwen; Lin,Haitao; Song,Xiaozong; Liu,Ping; Bo,Luji; Chen,Jianqiu; Yang,Li.
ABSTRACT:  The influences of byproduct amendments, containing silicon, calcium, magnesium and potassium, on acidic soil quality in Jiaodong Peninsula of China had been studied and compared with that of lime through monitoring physicochemical properties and enzyme activities of acidic soil over a 120-day period. Byproduct amendments (1125, 2250, 4500 and 9000 kg ha-1) and lime 2250 kg ha-1 was applied in the acidic soil. Results showed that both byproduct amendments and lime significantly increased the pH, EC and enzyme activities of soil. The by-product amendments inhibited microbial biomass carbon and soil respiration. Nevertheless, the lime-treated soil had a much more higher level of CO2 emission than the by-product amendments-treated soil. Compared to...
