14. Soil carbon and nitrogen stocks and fertility in areas in recuperation with leguminous trees and on shifting cultivation system area with high productivity. / Estoque de carbono, nitrogênio e fertilidade do solo em áreas em recuperação com leguminosas e em sistema de agricultura itinerante de alta produtividade .
This study aimed to evaluate carbon and nitrogen stocks restoration, and soil fertility status in land reclamation with nodulated and mycorrhizal legume trees and fallow length on high productivity shifting cultivation. Evaluations were made of soil C and N stocks, concentration of free and occluded light fraction and soil available Ca, Mg, P, K, C and N, an

15. Temporal effect of the soybean cultivation in the physical-chemical properties of the Mato Grosso state soil. / Efeito temporal da cultura da soja nos atributos físico-químicos do solo no Estado do Mato Grosso
Humanity as we know today is totally dependent in the large scale agriculture. We are getting close to the point where it will no longer be possible to expand or substitute agriculture areas. Making an evaluation of the agriculture system sustainability very important, to verify if they are fit to maintain there function as a food provider for a growing popu

16. Ammonium absorption and assimilation in two rice variets: carbon-nitrogen metabolism integration / Absorção e assimilação de amônio em duas variedades de arroz: uma integração entre o metabolismo de nitrogênio e de carbono.
About half of planet population depend on rice. In Brazil, this cereal crop is widely spread, and influenced by harsh climate conditions such as Humid Tropics one. In this region, certainly nitrogen is the most limiting nutrient. However, low insolation, acid and highly Al3+ satured soils still endangers the culture. In these soils, ammonium can be the singl

17. Avaliação do resíduo alcalino do refino de bauxita como condicionador de solos e do estabelecimento de dendê nos tanques de estocagem / Evaluation of red mud as soil conditioner and of the oil palm in stock tanks vegetated with leguminous trees
The production of aluminum and alumina generates a great amount of red mud, which is harmful to the environment mainly for its high pH, electric conductivity and concentration of sodium, which restrict plant growth. However, there are some indications that it may be used as a conditioner for acid sandy soils. This work tested a red mud from an alumina produc

18. Levels of metabolizable energy and crude protein in rations formulated according to the concept of ideal protein and phytase for piglets of 15 to 35 kg / NÃveis de energia metabolizÃvel e de proteÃna bruta em raÃÃes formuladas segundo o conceito de proteÃna ideal e fitase para leitÃes dos 15 aos 35 kg
Two experiments were conducted in the Swine Production Sector of the Animal Science Department at UFLA to verify by using the metabolism, performance assay, blood parameters and comparative slaughter, the effects of different levels of metabolizable energy (ME) and crude protein (CP) in rations formulated according to the ideal protein concept and phytase fo

19. Utilização da nisina na destribuição termica de Bacillus stearothermophilus em homogeneizado de cogumelos pH 6,2
The present work intended to establish the microbiological parameters for process using nisin as a thermal adjuvant in a homogenate of mushrooms in brine 1.5 per cent (p/v) pH 6.2 (HM). The HM simulates a low-acid processed product. The target microorganism for the thermo-chemical destruction was Bacillus stearotherraophilus FS 1518. The spore suspension was

20. Primary prodution of Santos Bay, Sao Paulo state: aspects of photosynthetic efficiency in a polluted environment / PRODUCAO PRIMARIA DA BAIA DE SANTOS, ESTADO DE SAO PAULO - ASPECTOS SOBRE A EFICIENCIA FOTOSSINTETICA NUM AMBIENTE MARINHO POLUIDO
The phytoplankton photosynthetic efficiency of Santos Bay was studied by means of water samples colected bimensaly, from February to December, 1976. Three points were sampled, the most characteristic of the different environments in the region: one station at the estuary mouth, one next to the beach and the last one at the bay entrance. The region is interes

21. Biology of Azospirillum-Sugarcane Association: Enhancement of Nitrogenase Activity †
Azospirillum brasilense was reisolated from associations with callus tissue cultures of sugarcane and compared with stock cultures of the inoculated bacterium and related strains. Although the reisolate had a growth rate similar to stock cultures, it exhibited a severalfold increase in maximum specific activity of nitrogenase. The reisolate and the parent cu

24. Resistance of Bacillus subtilis Spores to Inactivation by Gamma Irradiation and Heating in the Presence of a Bactericide: I. Suitability of Viable Count Procedures
A statistical evaluation of viable count procedures utilized for obtaining treatment survival curve data for Bacillus subtilis NCTC 8236 spores is described. Within the various recovery conditions tested, incubation on nutrient agar containing 1% dextrose for 48 hr at 37 C was found to promote the highest count of viable spores surviving a variety of bacteri
