1. Acid Ammonium Citrate as P Extractor for Fertilizers of Varying Solubility
ABSTRACT: There are several globally accepted methods to chemically characterize P-fertilizers, but not all are suitable to predict the agronomic efficiency of the P sources in terms of plant nutrition. Our aim was to investigate the performance of P extractors for fertilizers, investigating the consistency of different methods for P sources of varying prope

2. Reações de obtenção de NOx empregado no processo Humifert para a produção de compostos organofosfatados. / NOx reactions applied in a organophosphated compounds production by Humifert process.
Humiphert process is an alternative used for producing phosphated compound fertilizers with a slower solubilization when compared to other traditional fertilizers, resulting in a longer period of plant nutrition. During the process, phosphatic rocks are used along with some sort of limitation according to the normal development, both by their lower content p

3. Utilization of rocks and ectomycorrhizal fungi to promote growth of eucalypt
The utilization of rocks as fertilizers is limited by their low solubility. However, solubilization may be achieved by some micro-organisms, such as ectomycorrhizal fungi (ECMf). The aim of this study was to evaluate the potential of seven isolates of ECMf to solubilize two rocks, alkaline breccia and granite, and to liberate potassium and phosphorus for Euc

4. Eficiência agronômica de fosfatos de rocha, utilizados isoladamente ou associados ao superfosfato triplo, para a cultura da soja / Agronomic effectiveness of phosphate rocks, by itself or associated with the triple superphosphate, for soybean
due to a low natural availability of P in cultivated soils. To obtain good economically yield is necessary P fertilizer application. Nearly all phosphorus fertilization is carried out using acidulated phosphate, which have high water solubility and when applied in the soil may increase the P availability at times of low demand by the crop. To associate the u

5. Biofertilizantes de rochas fosfatadas e potássicas com enxofre inoculado com Acidithiobacillus na adubação da uva (Vitis vinifera L.) em planossolo do vale do São Francisco
A produção de biofertilizantes de rochas é um processo prático que reduz o consumo de energia e aumento da disponibilidade de nutrientes para as plantas, sem promover poluição ambiental. O teor de nutrientes dos biofertilizantes com P e K, varia com o método de preparo e com o material utilizado. Atualmente são denominados biofertilizantes os adubos

6. Uso de biofertilizantes de rochas com enxofre e Inoculado com acidithiobacillus em Argissolo Acinzentado do Vale do São Francisco cultivado com melão.
The production of biofertilizers from rocks is a practical process that may reduce the energy consumption and promote nutrients availability for plant growth. Nutrient content of P and K biofertilizers varied according to the methodology and the used material. Presently biofertilizers are known as fertilizers that are produced using different organic by-prod

7. Caracterização química de resíduos da produção de biodiesel compostados com adição mineral / Chemical characterization of residues from biodiesel production composted with mineral addiction
The production of biodiesel has in agriculture its base of sustentation. The culture of sugar cane and oleaginous species as castor oil plant after processing to obtain alcohol and vegetal oil, respectively, generates organic residues. These residues when used in agriculture in the compost form make possible the reduction of production costs and increase of
