Brazilian sedimentary zeolite use in agriculture. Repositório Alice
BERNARDI, A. C. de C.; OLIVEIRA, P. P. A.; MONTE, M. B. de; POLIDORO, J. C.; SOUZA-BARROS, F..
Zeolites are hydrated crystalline aluminosilicate minerals of alkaline and alkaline earth metals, structured in rigid three dimension nets, organized by AlO4 and SiO4 tetrahedral and are of natural occurrence. This report describes the characterization and application of the Brazilian zeolitic sedimentary rock as a release fertilizer and soil conditioner. The characterization of the head samples showed that it is composed of the zeolite stilbite intermixed with a smectitic clay mineral, and quartz. A low-cost quartz separation technique was established. Enrichment of concentrated natural zeolite was carried out: zeolite + KNO3, zeolite + K2HPO4 and zeolite + H3PO4 + apatite and the concentrated zeolite. These materials were tested with Rangpur lime...

Development, yield, and quality of melon fruit (Cucumis melo L.) inoculated with mexican native strains of Bacillus subtilis (Ehrenberg) Agrociencia
Abraham-Juárez,Ma. del Rosario; Espitia-Vázquez,Isidro; Guzmán-Mendoza,Rafael; Olalde-Portugal,Víctor; Ruiz-Aguilar,Graciela M. de la L.; García-Hernández,José L.; Herrera-Isidrón,Lisset; Núñez-Palenius,Héctor G..
Abstract Strains of Bacillus subtilis increase plant growth and yield. Consequently, the application of Mexican native strains of B. subtilis on greenhouse-grown melon (Cucumis melo L.) plants should induced a significant improvement on plant development and fruit quality. The objective of this study was to evaluate the effect of LAL-36, BEB-23, BEB-22 and BEB-13 B. subtilis strains, native to Mexico, on melon plant development and fruit quality. The strains were placed separately into the rhizosphere of melon plants under greenhouse conditions. Plants were grown in clinoptilolite type zeolite. Five treatments were evaluated: four inoculated with one of the four B. subtilis strains and one control without bacterial inoculum. A completely randomized design...

Effect of Feeding Transcarpathian Zeolite on Gastrointestinal Morphology and Function in Broiler Chickens Rev. Bras. Ciênc. Avic.
Wawrzyniak,A; Kapica,M; Stępień-Pyśniak,D; Szewerniak,R; Olejarska,A; Jarosz,Ł.
ABSTRACT Many kinds of feed additives can be used in chicken diets to stimulate intestinal morphological maturation and, consequently, intestinal function. The purpose of this study was to evaluate the effect of zeolite on broiler performance, gut morphology and gut digestive enzyme activity. The one-day old broiler chickens Ross 308 were assigned randomly into 3 groups with 30 birds per treatment. The 3 dietary treatments were: basal diet only (control group), basal diet + 2% zeolite, basal diet + 3% zeolite. Morphological and morphometric intestinal assessments were conducted using a light microscope. There was observed increase in villus height, villus perimeter, villus section area and crypt depth throughout duodenum and mid jejunum of the broilers fed...

Effects of dietary clinoptilolite and calcium levels on uric acid and calcium blood concentrations and bone quality of commercial layers Rev. Bras. Ciênc. Avic.
Berto,DA; Garcia,EA; Vercese,F; Santos,GC dos; Barreiro,FR; Molino,A de B; Pelícia,K; Silveira,AF da.
The objective of the present study was to evaluate the effect of clinoptilolite and calcium levels on uric acid and calcium blood profile and bone quality of commercial layers. A total of 576 birds were distributed according to a completely randomized experimental design in a 3x4 factorial arrangement (calcium levels of 2.5, 3.1, or 3.7% and clinoptilolite levels of 0.0, 0.15, 0.25, or 0.50%), into 12 treatments with six replicates of eight birds per cage (experimental unit). The experimental period was 112 days. The experimental diets were based on corn and soybean meal. Results were submitted to analysis of variance and means were compared by the test of Tukey at 5% significance level using SISVAR statistical package. Blood uric acid was significantly...

Maciel,Roberto Marinho; Lopes,Sonia Terezinha dos Anjos; Santurio,Janio Morais; Martins,Danieli Brolo; Rosa,Alexandre Pires; Emanuelli,Mauren Picada.
O objetivo deste trabalho foi avaliar os minerais séricos e as funções hepática e renal de frangos de corte, alimentados com dietas com aflatoxinas e dietas com aflatoxinas e argila clinoptilolita natural. Foram utilizados 528 frangos de corte machos, da linhagem Ross, distribuídos em seis tratamentos com quatro repetições cada: T1 - testemunha: ração sem aflatoxina ou clinoptilolita; T2 - ração com 5 ppm de aflatoxinas; T3 - ração com 0,25% de clinoptilolita; T4 - ração com 5 ppm de aflatoxinas e 0,25% de clinoptilolita; T5 - ração com 0,5% de clinoptilolita; e T6 - ração com 5 ppm de aflatoxinas e 0,5% de clinoptilolita. As aves foram submetidas aos tratamentos do 1º ao 42º dia de idade. Foram abatidos 72 animais, e foram analisadas as concentrações...

Loss of ammonia from nitrogen fertilizers applied to maize and soybean straw Rev. Bras. Ciênc. Solo
Faria,Letícia de Abreu; Nascimento,Carlos Antonio Costa do; Vitti,Godofredo Cesar; Luz,Pedro Henrique de Cerqueira; Guedes,Elaine Maria Silva.
In Brazilian agriculture, urea is the most commonly used nitrogen (N) source, in spite of having the disadvantage of losing considerable amounts of N by ammonia-N volatilization. The objectives of this study were to evaluate: N lossby ammonia volatilization from: [urea coated with copper sulfate and boric acid], [urea coated with zeolite], [urea+ammonium sulfate], [urea coated with copper sulfate and boric acid+ammonium sulfate], [common urea] and [ammonium nitrate]; and the effect of these N source son the maize yield in terms of amount and quality. The treatments were applied to the surface of a soil under no-tillage maize, in two growing seasons. The first season (2009/2010) was after a maize crop (maize straw left on the soil surface) and the second...

Urease activity according to the different inhibitors Anais da ABC (AABC)
GOMES,MATEUS P.; ZONTA,EVERALDO; STAFANATO,JULIANO B.; PEREIRA,ARIANA M..
Abstract The objective of this study was to evaluate NBPT, zeolite and humic acid in different concentrations as inhibitors of the activity of the enzyme urease. The activity of the urease enzyme was quantified by the methods proposed by May and Douglas (1976) and Witte and Medina-Escobar (2001). For this reason, two experiments were conducted in a completely randomized design in split plots, in which the incubation periods are the plots and the fertilizers with the inhibitors at the different concentrations are the subplots with three replications. Fifteen fertilizers based on NBPT-coated urea, humic acid and zeolite were used in different concentrations. The two methods of analysis used in the experiment confirmed the efficiency of NBPT in inhibiting the...

Zeolite and selenium application and their effects on production and physiological attributes of canola cultivars under water stress Agrociencia
Zahedi,Hossein; Shirani-Rad,A. Hossein; Tohidi-Moghadam,H. Reza.
To study the effects of zeolite and selenium (Se) application on production and physiological attributes of three canola (Brassica napus L.) cultivars under water stress, an experiment was conducted in two growing seasons (2006 and 2007), at Karaj, Iran. The experimental design was randomized complete blocks in factorial split plot with three replications, and three factors: 1) irrigation: complete and restricted at stem elongation stage; 2) zeolite: 0 and 10 t ha-1; 3) Se (as sodium selenate): 0, 15 and 30 g L-1. These treatments were randomized into Zarfam, Okapi and Sarigol canola cultivars. According to the results, Zarfam cultivar showed the lowest electrolyte leakage and the highest biological yield due to zeolite application and 30 g L-1 Se. The...

การใช้เม็ดดูดความชื้นซีโอไลท์ในการลดความชื้นของเมล็ดพันธุ์ข้าว Thai Agricultural
Porntip Thavong; Suwat Saimaya; Adoul Intaraprasert.
Seed drying to suitable moisture content during harvesting immediately and storage is a key factor to maintain a long-shelf life. The purpose of this research was to use the zeolite drying beads to dry rice seeds var. Phitsanulok 2 (PSL2) and Ayutthaya 1 (AYT1) to target moisture content at 6 % and 12 %. Three experiments were carried out at Prachinburi Rice Research Center during April 2012- January 2013. Rice seeds with the different initial moisture content were blended with three beads to seed ratios at 30oC, 40oC and ambient temperature. The results revealed that rice seed moisture content could be reduced to the target moisture content which depended on variety, initial moisture content, the bead-to-seed ratio, drying temperature and drying...
