Soil fertility in Santa Catarina State, Brazil, in 2004
da Veiga, Milton; Pandolfo, Carla Maria; Netto, José Maximiliano Müller; Andreola, Faustino; Flaresso, Jefferson AraújoThe soil fertility in four regions of Santa Catarina State, Southern Brazil, which were established bytheir similarity in parent material and climate conditions, was surveyed using 35,163 soil samples, analyzed in 2004 by five official laboratories in the State. The clay content increased from east to the west of the State, following the pattern of changes in parent material. In the same way increased the amoun...
Changes on chemical properties in the soil profile after 93 months of surface l...
Pandolfo, Carla Maria; da Veiga, MiltonLiming in no-till system is made on the soil surface, which requires long term for its reaction. Theobjective of this study was to evaluate the effect of superficial application of lime on some chemical properties in the profile of an acid soil, after long term, in no-till system. Soil was analyzed at seven layers up to 60cm deep, 93 months after the application of dolomitic lime doses, corresponding to zero, 1...
Effect of soil tillage and nutrient sources on soil fertility and corn growth a...
da Veiga, Milton; Reinert, Dalvan José; Pandolfo, Carla MariaThe general purpose of the tillage is to create a soil environment favorable to desired plant growthand development. However, tillage effects on soil properties can be affected by nutrient application through mineraland organic sources. This study was carried out at Epagri/Experiment Station of Campos Novos, in Santa CatarinaState, on a Typic Haplorthox soil, in order to evaluate long-term effect of using soil ...
Corn yield response to nitrogen fertilizer following winter cover crops in no-t...
Pandolfo, Carla Maria; da Veiga, Milton; Massignam, Angelo MendesCorn is highly responsive in yield to nitrogen (N) supply, but winter cover crops cultivated beforecould affect this response. The objectives of this study were to evaluate the corn response to N fertilization, when cultivated after black oat (Avena strigosa), rye (Secale cereale), common vetch (Vicia sativa) and oilseed radish (Rhaphanus sativus) in recently implanted no-till system, and to determine the N dos...
Soil mesofauna under different soil tillage systems and nutrient sources
Pandolfo, Carla Maria; Ceretta, Carlos Alberto; da Veiga, Milton; Girotto, EduardoThe agricultural practices affect the soil fauna which has an important role in the soil such asincorporation and decay of crop residues and to assist the action of microorganisms. The objective of this study was to analyze the influence of soil tillage systems and nutrient sources on soil mesofauna abundance and diversity. This study was carried out in Campos Novos, SC, Brazil, after nine years of trials. The ...
Physical attributes in a Hapludox after ten years of management with crop rotat...
da Veiga, Milton; Wildner, Leandro do Prado; Pandolfo, Carla MariaCrop rotation and cover crops may have direct and or indirect effects on soil physical properties. To study these effects,physical analyzes were performed on soil samples collected in the beginning of the eleventh year of conducting an experimentwith crop rotation systems, using as reference the soil kept continuously without vegetation (bare soil). The following variableswere analysed: saturated hydraulic cond...
Performance of maize inoculated with Azospirillum brasilense associated with do...
Pandolfo, Carla Maria; Vogt, Gilcimar Adriano; Balbinot Junior, Alvadi Antonio; Gallotti, Gilson José Marcinichen; Zoldan, Sérgio RobertoOne of the alternatives to reduce the consumption of nitrogen fertilizers in corn production is seed inoculation withdiazotrophic bacteria that have the ability of fixing atmospheric N in the root zone. The aim of this study was to evaluate someagronomic characteristics and grain yield of maize grown in an Oxisol with the presence and absence of seed´s inoculationwith Azospirillum brasilense associated with dif...
Performance of maize genotypes in presence or absence of seed inoculation with ...
Vogt, Gilcimar Adriano; Balbinot Junior, Alvadi Antonio; Gallotti, Gilson José Marcinichen; Pandolfo, Carla Maria; Zoldan, Sérgio RobertoThe objective of this research was to evaluate the performance of maize genotypes in presence or absence of seedinoculation with A. brasilense and nitrogen fertilization. The experiments were carried out in Papanduva and Campos Novos,Santa Catarina State, Brazil, during 2011/12 and 2012/13 cropping seasons. The experimental design was a complete blockswith three replications in a 8x2x2 factorial scheme. Eight g...
Spatial distribution of chemical soil attributes in the State of Santa Catarina...
Pandolfo, Carla Maria; da Veiga, Milton; Spagnollo, Evandro; Pandolfo, Cristiana; Hammes, Luiz AlbanoThe mapping of soil chemical properties constitutes a tool for planning actions to correct those who have limitingvalues for agricultural production in some region. The spatial distribution of some of these attributes in the State of SantaCatarina, was determined from standardized collection of samples of two fields with the use and management systems morerepresentative of each region. The samples were collecte...
Crop yield and levels of P in soil in terms of doses and forms of phosphate fer...
Pandolfo, Carla Maria; da Veiga, MiltonThe doses and forms of phosphate fertilizer application in the soil can influence crop yield and phosphorus distribution in the profile. The objective of this study was to examine the response of crops to the application of P and the distribution of its contents in the profile of a Hapludox after seven years. We applied doses of 0, 20, 40, 60 and 80kg/ha of P2 O5 broadcast and in the furrow, in no-till system, ...
