| En el sistema de cultivo Milpa Intercalada con Árboles Frutales (MIAF) más pobre en organismos del suelo y de menores contenidos de nutrientes para los cultivos, seleccionado mediante caracterización biológica y fisicoquímica de 8 MIAF ubicados en Huejotzingo-Chiautzingo, Pue. y en San Jerónimo Tecoatl, Oaxaca, se realizó un experimento de campo en Chiautzingo, empleando técnicas de bioestimulación (aplicación de enmiendas orgánicas: alfalfa cortada de la misma parcela, chícharo cultivado in situ y estiércol de vacuno) y de bioaumentación (inoculación de las lombrices de tierra: Lumbricus rubellus Hoffmeister, 1843 y Aporrectodea trapezoides Dugès, 1828, epigea y endógea, respectivamente), sobre el suelo cultivado con árboles de durazno, para evaluar sus... |

| In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock use, around 85% of the nitrogen (N) returning to the soil is through animal feces and urine. However, there is a lack of information concerning the rate of nutrient return into the soil from animal feces in Southern Patagonia. In this study, we evaluated the rate of sheep faeces decomposition and nutrient (N, P, Ca and K) release in three different ecological areas of Southern Pat agonia, representing a West to East environmental gradient. Samples of fresh sheep dung were collected in the field, processed in the laboratory and located in... |

| ABSTRACT Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The objective of this study was to evaluate the soil chemical properties and the leachate in face of the association of swine wastewater and mineral fertilization (MF) in oat cultivation. An experiment in drainage lysimeter was carried out, using SW applications associated to MF or not, where treatments consisted of doses of 0, 100, 200 and 300 m3ha-1 with the absence or presence of MF, under field... |

| ABSTRACT The gelatin industry wastewater has nutrients in its composition, allowing its use in agriculture as an alternative to disposal and recycling of this residue. However, high application rates can cause the accumulation of elements such as sodium in the soil, and generate negative impacts on the environment. This study aimed to evaluate the effects of the application of rates up to 600 m3ha-1 of gelatin industry wastewater in soil columns, on soil chemical attributes in five depths. The experiment was conducted in a greenhouse, in PVC tube columns (0.20 m diameter) filled with distroferric Red Nitosol soil, of very clayey texture. The treatments consisted of increasing rates of wastewater equivalent to 0, 150, 300, 450 and 600 m3 ha-1, with a single... |

| ABSTRACT: The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are inserted. In this sense, the aim of this study was to assess the impact of swine wastewater and mineral fertilization application on soil, soybean crop, and leachate characteristics. The experiment was developed in drainage lysimeters under field conditions. The following doses of swine wastewater were applied: 0, 100, 200, and 300 m3 ha−1, both with and without mineral fertilization. Swine wastewater application contributed to increasing soil nutrients; however, a special attention should be paid to Cu+ and Zn+ accumulation, which... |

| ABSTRACT this research aimed to evaluate the residual effect of doses of organic compost on the radish production, as well as its effect on soil chemical properties. experiments were conducted in two areas (“low” and “high” soil fertility). prior to this, these areas were first used to evaluate the influence of organic compost doses on endive production. after harvesting endive, radish seeds were sown into the same plots used for endive to evaluate the residual effect. the six treatments consisted of organic compost doses (0, 35, 70, 105, 140 and 175 t ha-1), evaluated in a complete block experimental design, with four replications. vegetative characteristics of radish plants (shoot, root and total fresh and dry matter weight, plant height and root... |

| ABSTRACT The authors evaluated the effects of doses of organic compost on the production and accumulation of macronutrients in endive plants in two areas with different fertility levels. The experiments were carried out at Fazenda Experimental São Manuel, located in the municipality of São Manuel, São Paulo State, Brazil. The study was carried out in a completely randomized design with seven treatments, six doses of organic compost (0, 35, 70, 105, 140 and 175 t/ha) and one additional treatment with inorganic fertilizer (N-P-K 4-14-8) and four replicates. In both areas, when the dose of organic compost was increased, the authors noticed a linear increase in fresh matter weight, number of leaves and plant height. In high-fertility area, compared to control... |

| Procurou-se avaliar o efeito de tres fontes de fosforo na produtividade do capim coloniao. O experimento foi conduzido no campo experimental da EMBRAPA-UEPAT Porto Velho, com solo Latossolo Amarelo textura pesada. Usou-se o delineamento experimental blocos ao accaso, com 3 repeticoes. Resultados demostraram que o uso tanto do superfosfato triplo, como do superfosfato simples aplicados isolados ou combinados entre si, e/ou combinados com hiperfosfato, mostraram-se bastante eficazes no aumento da produtividade do capim coloniao, ficando a escolha das fontes, na dependencia dos seus custos; o uso do hiperfosfato aplicado isoladamente nao mostrou grande eficiencia, mesmo sendo superior a testemunha; independente das fontes testadas, o fosforo proporcionou... |
