Does Ferralsol Clay Mineralogy Maintain Potassium Long-Term Supply to Plants?

Diovane Freire Moterle ORCID logo , Edson Campanhola Bortoluzzi, João Kaminski, Danilo dos Santos Rheinheimer, Laurent Caner


ABSTRACT Ferralsols ( Latossolos ) should contain few or no 2:1 clay minerals and have low potassium (K) contents, and consequently low levels of non-exchangeable K forms are expected. The aim of this study was to evaluate how the clay mineralogy of a Ferralsol affects the soil K dynamics in response to K fertilization during cropping and whether the clay mineralogy was altered due to successive crops and K fertilization. A tropical Brazilian Ferralsol under field conditions was sampled (0.00-0.20 […]

Soybean root growth and crop yield in reponse to liming at the beginning of a no-tillage system

Edson Campanhola Bortoluzzi, Guilherme Luis Parize, Jackson Korchagin, Vanderlei Rodrigues da Silva, Danilo dos Santos Rheinheimer, João Kaminski


Analyzing the soil near crop roots may reveal limitations to growth and yield even in a no-tillage system. The purpose of the present study was to relate the chemical and physical properties of soil under a no-tillage system to soybean root growth and plant yield after five years of use of different types of limestone and forms of application. A clayey Oxisol received application of dolomitic and calcitic limestones and their 1:1 combination in two forms: surface application, maintained on […]

Spectroscopic quantification of soil phosphorus forms by 31p-nmr after nine years of organic or mineral fertilization

Luciano Colpo Gatiboni, Gustavo Brunetto, Danilo dos Santos Rheinheimer, João Kaminski, Carla Maria Pandolfo, Milton Veiga, [...]


Long-standing applications of mineral fertilizers or types of organic wastes such as manure can cause phosphorus (P) accumulation and changes in the accumulated P forms in the soil. The objective of this research was to evaluate the forms of P accumulated in soils treated with mineral fertilizer or different types of manure in a long-term experiment. Soil was sampled from the 0-5 cm layer of plots fertilized with five different nutrient sources for nine years: 1) control without fertilizer; 2) […]

Evaluation of Sikora instead of SMP buffer to estimate the potential acidity of brazilian soils

Maria Alice Santanna, João Kaminski, Danilo dos Santos Rheinheimer, Jaderson dos Anjos Toledo, Carlos Alberto Casali


Despite the efficiency of the Shoemaker, McLean, Pratt (SMP) buffer method in estimating soil acidity, the presence of p-nitrophenol and potassium chromate in the solution, both hazardous substances, has caused increasing environmental concerns. The purpose of this study was to test Sikora method (Sikora, 2006) as an alternative to the adapted SMP buffer method, generally used to estimate potential acidity of Southern Brazilian soils. For the test, 21 soils in the South and Cerrado regions of Brazil were sampled. (1) […]

Potassium availability in a hapludalf soil under long term fertilization

João Kaminski, Diovane Freire Moterle, Danilo dos Santos Rheinheimer, Luciano Colpo Gatiboni, Gustavo Brunetto


In a system in which fertilization is recommended, diagnosis of soil K availability and the establishment of critical levels are made difficult by the possibility of a contribution of non-exchangeable forms of K for plant nutrition. Due to its magnitude, this contribution is well diagnosed in long term experiments and in those which compare fertilization systems with positive and negative balances in terms of replacement of the K extracted by plants. The objective of this study was to evaluate K […]

Contribution of soil constituents to the cation exchange capacity as determined by different extraction methods

Edson Campanhola Bortoluzzi, Danilo dos Santos Rheinheimer, Claudia Petry, João Kaminski


The cation exchange capacity (CEC) is a physicochemical property dependent on mineral and organic soil constituents. Despite the use of different procedures and extractors the CEC is normally expressed considering only the pH control or not of the extracted solution. This study aims to discuss the significance of the contribution of organic carbon and clay to the CEC of an Acrisol, using different determination methods. For this purpose, 75 samples of an abruptic Red-Yellow Acrisol from the Universidade Federal de […]

Effects of liming on the relationship between soil and water

Edson Campanhola Bortoluzzi, Leandro Garbozza, Caroline Guareschi, Danilo dos Santos Rheinheimer


Changes in the physical properties of soil, mainly related to water retention and soil aggregation, may be linked to changes in electrochemical soil properties. The purpose of this study was to determine the effects of liming on the relationship between soil and water. In 1994, an experiment was installed in the experimental area of the Departamento de Solos da Universidade Federal de Santa Maria, in a dystrophic plinthic Gray Acrisol. Treatments consisted in surface liming and lime incorporation at 0, […]

Copper forms and desorption in soils under grapevine in the Serra Gaúcha of Rio Grande do Sul

Carlos Alberto Casali, Diovane Freire Moterle, Danilo dos Santos Rheinheimer, Gustavo Brunetto, Adão Leonel Mello Corcini, João Kaminski, [...]


Successive applications of cupric fungicides to grapevine can increase total copper concentration in the soil and modify its desorption in the soil profile. This study was carried out in 2006 in the soil chemistry and fertility laboratory of the Universidade Federal de Santa Maria to evaluate copper forms and desorption dynamics in Udorthent and Haplumbrept soils (in the layers 0-20 and 20-40 cm) under grapevine for 40 years and under successive applications of cupric fungicides. The soils were collected in […]

Soil phosphorus forms after successive pig slurry application in a native pasture

Luciano Colpo Gatiboni, Gustavo Brunetto, João Kaminski, Danilo dos Santos Rheinheimer, Carlos Alberto Ceretta, Claudir José Basso


The swine industry generates large amounts of pig slurry (PS), which is reused as agricultural fertilizer. However, if applied at excessive rates, pig slurry becomes a severe environmental pollutant. The objective of this study was to evaluate forms of soil phosphorus accumulation after successive swine manure applications. The experiment was installed in 1995, in an area of native pasture. Rates of 0, 20 and 40 m3 ha-1 of PS were applied periodically (at 45 to 60 days intervals) during five […]

Comparison of determination methods of total organic carbon in soils

Danilo dos Santos Rheinheimer, Ben-Hur Costa de Campos, Sandro José Giacomini, Paulo Cesar Conceição, Edson Campanhola Bortoluzzi


The total organic carbon (TOC) in soils can be estimated by dry and humid combustion methods. Both have some drawbacks, mainly the humid combustion, which demands high reagent quantities and generates toxic waste containing chromium. The Mebius in Block method was developed to decrease the quantity of Na dichromate used in analyses. The objectives of this study were to verify the precision and accuracy of the Mebius in Block compared with other wet and dry combustion methods. The study was […]
