Adubarroz: a brazilian experience for fertilization and liming recommendation of irrigated rice via computational system Ciência Rural
Carmona,Felipe de Campos; Anghinoni,Ibanor; Martins,Amanda Posselt; Boeni,Madalena.
ABSTRACT: Recommendations for fertilizing irrigated rice in southern Brazil have been constantly evolving over years. In this process, the influence of factors such as the development cycle of varieties and sowing period increased. Thus, computational tools that take these and others important aspects into account can potentiate the fertilization response of rice. This study describes the computer program "ADUBARROZ". The software provides recommendations of fertilizer rates and liming requirements of irrigated rice, based on information entered by the user. The system takes various factors that regulate the crop response to fertilization into account. A final report is established with the graphical representation of input management over time.

Alternative liming blends for fish culture Animal Sciences
Nobre, Mikaely Karine Barbosa; Universidade Federal do Ceará; Lima, Francisco Roberto dos Santos; Universidade Federal do Ceará; Magalhães, Frederico Batista; Universidade Federal do Ceará; Sá, Marcelo Vinícius do Carmo e; Universidade Federal do Ceará.
Calcium carbonate (limestone) is a safe but slow-acting product for aquaculture liming. Calcium oxide (lime) is a fast-acting but dangerous product. It would be interesting to have simultaneously a safe and fast-acting liming product. The present work aimed to evaluate two alternative liming blends for tilapia culture. The culture water was initially acidified with HCl. Next, the same quantity of CaCO3 (control), Na2CO3+CaSO4 or Na2CO3+CaCl2 was applied to the culture water. There were also non-limed tanks. One hundred and twenty Nile tilapia juveniles (1.6 ± 0.1 g) were stocked in twenty 250-L culture tanks for 10 weeks. All products used were similarly efficient in increasing the alkalinity of water. The probable better environment for algal growth in...

Application of alkaline waste from pulp industry to acid soil with pine Rev. Bras. Ciênc. Solo
Pértile,Patricia; Albuquerque,Jackson Adriano; Gatiboni,Luciano Colpo; Costa,André da; Warmling,Maria Izabel.
In Brazil extensive areas are covered with pine forests, planted for pulp and paper production. This industry generates solid alkaline waste, such as dregs. The application of this dregs to forest soils is an alternative for soil acidity correction and plant nutrient supply, as well as a solution for its proper disposal. The purpose of this study was to compare the residual effect of surface application of dregs and dolomitic lime on (a) changes in the physical and chemical properties of an acidic soil and (b) pine tree development. The experiment was carried out in 2004 in Bocaina do Sul, Santa Catarina, consisting of the application of increasing dreg and lime rates to a Pinus taeda L. production area, on a Humic Cambisol, in a randomized block design...

Bean cultivation in a subsistence farming system in the northeast of São Paulo state - Brazil Scientia Agricola
Oliveira,Wladecir Salles de; Tsai,Siu Mui.
The colonization of the State of São Paulo, Brazil of the northeastern region, is related to historical movements, such as "tropeirismo" (séc. XVIII and XIX) and Italian immigration (séc. XIX). The agriculture presently practices used by farmers descendent of immigrants does not differ from the techniques used at the beginning of the century. In the Cunha region of the Atlantic Rain Forest ecosystem poor bean yield associated with low fertilizer input, plant disease and soil erosion led to slash-and-burn farming. This work is an attempt at identifying sustainable farming practices that would minimize bean disease and maximize nitrogen assimilation. For that purpose soil fertility and plant cultivar were studied under standard agronomic practices to...

Carbonate-silicate ratio for soil correction and influence on nutrition, biomass production and quality of palisade grass Scientia Agricola
Souza,Renato Ferreira de; Ávila,Fabrício William; Faquin,Valdemar; Pozza,Adélia Aziz Alexandre; Carvalho,Janice Guedes; Evangelista,Antônio Ricardo.
Silicates can be used as soil correctives, with the advantage of being a source of silicon, a beneficial element to the grasses. However, high concentrations of silicon in the plant would affect the digestibility of the forage. To evaluate the influence of the substitution of the calcium carbonate by calcium silicate on the nutrition, biomass production and the feed quality of the palisade grass [Urochloa brizantha (C. Hochstetter ex A. Rich.) R. Webster], three greenhouse experiments were conducted in completely randomized designs with four replications. Experimental units (pots) contained a clayey dystrophic Rhodic Haplustox, a sandy clay loam dystrophic Typic Haplustox and a sandy loam dystrophic Typic Haplustox. Each soil received substitution...

Correction of soil acidity in the subsurface of an oxisol with sandy loam texture under no-tillage Rev. Bras. Ciênc. Solo
Rossato,Otavio Bagiotto; Ceretta,Carlos Alberto; Silva,Leandro Souza da; Brunetto,Gustavo; Adorna,Jaqueline Cristiane; Girotto,Eduardo; Lorenzi,Cledimar Rogério.
In Rio Grande do Sul State (RS), Southern Brazil, aluminum saturation in many areas under no-till system is high and base saturation low in the 0.10-0.20 m layer (subsurface), which may reduce the grain yield of annual crops. The objective of this study was to evaluate if the occurrence of high aluminum saturation and low base saturation in the subsurface, under a no-till system, represents a restrictive environment for crop production, as well as to evaluate forms of lime incorporation for soil acidity correction in the subsurface. For this purpose, an experiment was carried out with soybean (2005/2006), corn (2006/2007), wheat (2007) and soybean (2007/2008) crops, in a Rhodic Hapludox (USDA, 1999) with sandy loam texture, under no-till for four years in...

Effect of Nitrogen Fertilization and Liming on Rye-Ryegrass Yield and Soil pH Dynamics AgEcon
Tumusiime, Emmanuel; Brorsen, B. Wade; Biermacher, Jon T.; Mosali, Jagadeesh.
Using ammonium based nitrogen fertilizers in crop production has been shown to acidify soils. Lime used to correct soil pH is an important cost to producers. Recommendations of the optimal level of nitrogen to apply typically ignore the cost of lime created by nitrogen fertilization. This study was aimed to estimate soil pH change in response to nitrogen and lime application, and determine the effect of considering the cost of lime on recommendations about the optimal level of nitrogen. Yield response and pH functions were estimated and used to determine optimal levels of inputs. The effect of the cost of lime on recommendations about the optimal level of nitrogen was found to be marginal. Nitrogen acidification was found to be more severe with nitrogen...

Extraction of essential oils from lime (Citrus latifolia Tanaka) by hydrodistillation and supercritical carbon dioxide BABT
Atti-Santos,Ana Cristina; Rossato,Marcelo; Serafini,Luciana Atti; Cassel,Eduardo; Moyna,Patrick.
In this work lime essential oils were extracted by hydrodistillation and supercritical carbon dioxide. In the case of hydrodistillation, the parameters evaluated were extraction time and characteristics of the plant material. In supercritical extraction, the parameters evaluated were temperature, pressure, CO2 flow, extraction time and material characteristics. Considering citral content, the best results for hydrodistillation were obtained with a distillation time of 3 hours using whole peels. The best results for supercritical extraction were found using 60ºC, 90 bar, at a CO2 flow rate of 1 mL/ min for 30 minutes using milled peels. The best yields of lime oil were obtained by hydrodistillation (5.45% w/w) and supercritical extraction (7.93% w/w) for...

Liming and fertilization to restore degraded Brachiaria decumbens pastures grown on an entisol Scientia Agricola
Oliveira,Patrícia Perondi Anchão; Boaretto,Antonio Enedi; Trivelin,Paulo Cesar Ocheuze; Oliveira,Wladecir Salles de; Corsi,Moacyr.
The reconstitution of soil fertility is essential in the process of pasture restoring, liming being the first action to be taken in this direction. The liming recommendation for pastures needs more technical information as the application method and rate. A field experiment was carried out to evaluate the liming and fertilization practices to restore a degraded Brachiaria decumbens pasture. The following factors were studied: liming method (incorporated in soil by disking or not); level of base saturation (40, 50 or 80%) and lime type (55, 70 or 90 of ECC). Liming and fertilization (NPK and micronutrients) increased both the forage yield and its root system, these being more evident in the second year, even using the same rates of lime and fertilizer used...

Liming and postharvest quality of carambola fruits BABT
Prado,Renato de Mello; Natale,William; Corrêa,Márcio Cleber de Medeiros; Silva,José Antônio Alberto da.
To determine the effects of lime application on the postharvest quality of carambola fruit, an experiment with carambola trees cultivated on an acid soil was conducted at the Bebedouro, São Paulo, Brazil. The trees were treated with increasing doses of lime during the pre-planting period. Liming led to a increase in calcium concentration of carambola leaves and fruits. Adequate nutrition of the plant with calcium improved post-harvest fruit quality, permitting a longer (~ 2 days) period of storage under ambient conditions.

Nitrate role in basic cation leaching under no-till Rev. Bras. Ciênc. Solo
Crusciol,Carlos Alexandre Costa; Garcia,Rodrigo Arroyo; Castro,Gustavo Spadotti Amaral; Rosolem,Ciro Antonio.
Especially under no-tillage, subsuface soil acidity has been a problem, because it depends on base leaching, which has been associated with the presence of low molecular weigth organic acids and companion anions. The objective of this study was to evaluate exchangeable base cation leaching as affected by surface liming along with annual urea side-dressing of maize and upland rice. Treatments consisted of four lime rates (0, 1500, 3000, and 6000 kg ha-1) combined with four nitrogen rates (0, 50, 100, and 150 kg ha-1) applied to maize (Zea mays) and upland rice (Oryza sativa), in two consecutive years. Maize was planted in December, three months after liming. In September of the following year, pearl millet (Pennisetum glaucum) was planted without...
