| The objective of this study was to evaluate the effects of poultry litter and Organosuper® with three modes of application on the biomass production and nutrient content of the leaves of roselle plants. The treatments in each crop cycle were in a factorial arrangement, 2 x 3 + 1, composed of a control and combinations of the two organic fertilizers (poultry litter (10 ton. ha-1) and Organosuper® (10 ton. ha-1) and the three application modes (surface, incorporated and surface + incorporated), in a randomized block design with four replicates. In the surface + incorporated mode, the organic fertilizers were applied as 5 ton. ha-1 surface and 5 ton. ha-1 incorporated. The highest productions of fresh and dry weight and number of calyxes were obtained for... |

| Peat is an unconsolidated deposit of semi-carbonized plant matter. Peat is usually found in water-saturated environments and has certainly high moisture content. Haors are peat-dominated areas in Bangladesh, which hold the largest peat reserves of the country. Peat is one of the most important mineral resources worldwide. For the utilization of peat similar to other countries, it is necessary to know its energy and fertility potential and develop a sustainable management strategy for peatlands in Bangladesh. This study mainly focused on the heating and fertility potentials of peat in Bangladesh and on strategies to sustainably manage these peatlands. This study was carried out in the haor-based Katiadi and Mohanganj upazilas in the Kishoreganj and... |

| The potential toxicity of urban sewage and farmed salmon sludge, as well as their fertilizer potential, was evaluated by a battery of tests carried out with lettuce (Lactuca sativa L.) and annual ryegrass (Lolium multiflorum Lam.) cv. Winter Star. Wastes were evaluated in a Patagonian soil (Andic cryofluvent) and a granitic soil (Ultic Palexeralf). The treatments were municipal sewage sludge (MSS), salmon ground-farming waste (PSW) and salmon lake-farming waste (LSW) at different rates: 25, 50, 75, 100 and 150 t ha-1. Bioassays in lettuce were conducted for germination index (GI), radicle and hypocotyl structure length. Test in ryegrass were conducted for aboveground biomass yield. The phytotoxicological results from Patagonian soil showed significant... |

| Nowadays much of the chemical fertilizers used in Brazil come from imports, what creates the necessity to seek for alternative fertilizers. One possibility is organic fertilizers, including poultry litter, which presents increasing availability in various regions of the country, due to the expansion of the poultry industry. Despite its availability, there are no enough studies that show the benefits of using poultry litter on soybeans in substitution of mineral fertilizer. The present study aimed to evaluate the effect of different doses of poultry litter on leaf chlorophyll content, nodulation, and development of soybean plants. It was used a completely randomized design with five doses of poultry litter (0, 1, 2, 4 and 8 t ha-1) and a control with... |

| ABSTRACT: This research aimed to evaluate the mineralization of nitrogen (N) and to define the efficiency index (EI) of N after the addition of organic fertilizers based on cattle manure on the soil under laboratory conditions. A completely randomized statistical design with four replicates was used. The treatments were set as follows: T1) Soil (control); T2) Soil + vermicompost of cattle manure (CMV); T3) Soil + cattle manure and straw compost (CMS); and T4) Soil + cattle manure (CM). Experimental units were constituted by acrylic flasks with 5 x 5cm (height x diameter). Each flask was added with 135g of wet soil and 2.20, 2.45 and 2.27g of CMV, CMS and CM, respectively. Treatments were incubated at 25°C and the amount of mineral N from the soil (N-NH4+... |

| En la Mixteca Poblana, predominan suelos calcáreos que por su pH alcalino impiden que las plantas puedan absorber los nutrimentos como hierro y zinc, ocasionando la clorosis férrica, afectando los cultivos de esta región, tales como: caña de azúcar, sorgo, maíz, frijol e incluso los árboles frutales, repercutiendo en el desarrollo, rendimiento y en casos severos la muerte de la planta. En esta región está ubicado el ingenio azucarero de Atencingo que genera anualmente 45 mil toneladas de desechos orgánicos (cachaza). El objetivo de esta investigación fue evaluar el efecto de la incorporación de compost de cachaza al suelo en la corrección de clorosis férrica y rendimiento de sorgo. Se incorporó compost de cachaza a razón de cero, cinco y diez t ha-1 en... |

| The goal of this study was to evaluate the nitrogen fertilization as deep litter for pigs in order to produce biomass and accumulate nutrients by the corn. A deep litter made of rice husk as organic compound, from a commercial pig farm during finishing phase, was used. After three consecutive batches of pigs, the deep litter was subjected to a maturation period of 50 days, and samples of this material were taken for analysis of agronomic value. The experimental design was completely randomized with five replicates. The treatments consisted of doses of 0, 75, 150 and 300mg dm-3 of N of deep litter, as well as an additional treatment with ammonium sulfate, with a dosage of 150mg dm-3 of N. After 45 days, corn plants were harvested in order to evaluate the... |
