Potassium Fertilization of Eucalyptus in an Entisol in Low-Elevation Cerrado

Rodolfo de Niro Gazola, Salatiér Buzetti, Marcelo Carvalho Minhoto Teixeira Filho ORCID logo , Raíssa Pereira Dinalli Gazola, Thiago de Souza Celestrino, Alexandre Costa da Silva, [...]


ABSTRACT Potassium (K) is one of the most highly accumulating nutrients in Eucalyptus and, consequently, is heavily exported by the harvesting of wood. Moreover, its availability in the soil in most Brazilian plantation areas is very low, especially in the regions of the Cerrado biome, which has soils with low natural fertility and marked water deficits, implying a lack of nutrient supply and, consequently, a less efficient water use. Our objective was to evaluate the effects of K fertilization on […]

Corn Yield and Foliar Diagnosis Affected by Nitrogen Fertilization and Inoculation with Azospirillum brasilense

Fernando Shintate Galindo, Marcelo Carvalho Minhoto Teixeira, Salatiér Buzetti, José Mateus Kondo Santini, Cleiton José Alves, Lais Meneghini Nogueira, [...]


ABSTRACT The biological nitrogen fixation (BNF) process in grasses is caused by diazotrophic bacteria, particularly Azospirillum brasilense. However, studies are lacking on BNF efficiency to define how much mineral nitrogen (N) can be applied to achieve more sustainable high yields. Furthermore, there should be an analysis of whether urea with the urease enzyme inhibitor NBPT is less harmful, benefiting BNF in grasses. The objective of this study was to evaluate the effect of N sources and N rates associated with […]

Nitrogen application rates, sources, and times affecting chlorophyll content and wheat yield

Eduardo Quimello Theago, Salatiér Buzetti, Marcelo Carvalho Minhoto Teixeira Filho, Marcelo Andreotti, Marcio Mahmoud Megda, Cleiton Gredson Sabin Benett


To achieve high wheat yield, correct management of N fertilization and the use of high yield potential cultivars are necessary. The aim of this study was to evaluate the effects of different application rates and sources of N, applied totally at sowing or in topdressing, on grain yield and yield components of two irrigated wheat cultivars under a no-till system, grown in a Cerrado (Brazilian tropical savanna) region of low altitude. A randomized block design was used in a 5 […]

Macronutrient accumulation and decomposition of brachiaria species as a function of nitrogen fertilization during and after intercropping with corn

Nídia Raquel Costa, Marcelo Andreotti, Salatiér Buzetti, Keny Samejima Mascarenhas Lopes, Fernanda Garcia dos Santos, Cristiano Magalhães Pariz


In regions with a tropical climate, the greatest limitations for straw maintenance on the soil surface are difficulties on its establishment and high rates of decomposition. With the aim of identifying the productive potential of Xaraes and Ruziziensis grasses, as well as subsequent straw formation for continuity of the no-tillage system, the following factors were evaluated: the dry matter yield, the lignin/total N ratio, macronutrient accumulation, and straw decomposition in two growing seasons. The treatments consisted of two Brachiaria species […]

Straw decomposition of nitrogen-fertilized grasses intercropped with irrigated maize in an integrated crop-livestock system

Cristiano Magalhães Pariz, Marcelo Andreotti, Salatiér Buzetti, Antonio Fernando Bergamaschine, Nelson de Araújo Ulian, Luciano Coletti Furlan, [...]


The greatest limitation to the sustainability of no-till systems in Cerrado environments is the low quantity and rapid decomposition of straw left on the soil surface between fall and spring, due to water deficit and high temperatures. In the 2008/2009 growing season, in an area under center pivot irrigation in Selvíria, State of Mato Grosso do Sul, Brazil, this study evaluated the lignin/total N ratio of grass dry matter , and N, P and K deposition on the soil surface […]

Yield and development of plant cane and ratoon cane as related to manganese rates and sources

Cleiton Gredson Sabin Benett, Salatiér Buzetti, Katiane Santiago Silva, Marcelo Carvalho Minhoto Teixeira Filho, Cássia Maria de Paula Garcia, Paulo Ricardo Maestrelo


Sugar cane plays an important economic-social and political role in Brazil. This study aimed to evaluate the effect of manganese doses and sources on sugar cane. The experiment was conducted on the Sitio Fujimoto, an area administered by the Distillery Vale do Paraná S/A Alcohol and Sugar in Suzanápolis, São Paulo state. The experiment was arranged in a randomized block, 5 x 3 factorial design, with 5 manganese rates (0, 2.5, 5.0, 7.5 and 10.0 kg ha-1) and 3 sources […]

Response of irrigated wheat cultivars to different nitrogen rates and sources

Marcelo Carvalho Minhoto Teixeira Filho, Salatiér Buzetti, Marcelo Andreotti, Marco Eustáquio de Sá, Orivaldo Arf, Márcio Mohamed Megda


High wheat yields require good N fertilization management. The objective of this study was to evaluate the effects of different N applications at sowing using Entec (N source with nitrification inhibitor) and urea (traditional N source) at covering, on four wheat cultivars. The experiment was conducted in a randomized block design in a factorial scheme, with four replications, at the Experimental Station of the Faculdade de Engenharia de Ilha Solteira – UNESP, on a dystrophic, epi-eutrophic alic Red Latosol with […]

Limestone application methods and cover crops in the implementation of the no-till system on a cerrado soil

Aguinaldo José Freitas Leal, Edson Lazarini, Leandro Rebuá Rodrigues, Cid Tacaoca Muraishi, Salatiér Buzetti, Hipólito Assunção Antonio Mascarenhas


The objective of this study was to evaluate soil correction in the implantation of the no-till system in an Oxisol of the Cerrado, Selvíria – MS, Brazil (20º 22´ S, 51º 22´ W). The treatments consisted of five lime application forms, in only one or split rates and two cover crops. Liming without incorporation, independent of the application form, corrected soil acidity and increased Ca and Mg levels in the 0-0.05 m layer; in the other layers these attributes were […]

Nitrogen sources and application times in no-till wheat on cerrado soil

Simone Aparecida da Silva, Orivaldo Arf, Salatiér Buzetti, Matheus Gustavo da Silva


Nitrogen is an important nutrient, due to its soil dynamics and crop demand. The amount of N supplied by the soil is however frequently insufficient, and N fertilization is required to obtain maximum yields. This study was conducted with the objective of evaluating different sources and periods of N application in no till wheat. A randomized block design was used in a factorial scheme 2×6 with four replications. The treatments consisteded of the combination of two N sources: Urea and […]

Utilization of nitrogen from corn plant residues and green manures by corn

Edson Cabral da Silva, Takashi Muraoka, Salatiér Buzetti, Freddy Sinencio Contreras Espinal, Paulo César Ocheuze Trivelin


The quality of commercial crop residues and green manure influences the N mineralization-immobilization rate and the respective use by subsequent crops. With the objective of evaluating N utilization by corn of N from the shoot and root system of sunnhemp (Crotolaria juncea) and millet (Pennicetum americanum) and corn straw, labeled with 15N, a green house experiment was carried out at the Centro de Energia Nuclear na Agricultura (CENA/USP), Piracicaba, S. Paulo, Brazil, in 5 kg pots with dystroferric Red Latosol […]
