| A manutenção dos resíduos vegetais sobre o solo, o tipo de resíduo e sua velocidade de decomposição são de grande importância no estudo da ciclagem de nutrientes. Este estudo foi desenvolvido na área experimental do IAPAR - Pato Branco-PR, onde foram avaliados seis resíduos de coberturas de inverno: tremoço azul (Lupinus angustifolius L.), ervilhaca comum (Vicia sativa L.), aveia preta (Avena strigosa S.), nabo forrageiro (Raphanus sativus L.), centeio (Secale cereale L.) e trigo (Triticum aestivum L.), sob Sistema Plantio Direto (SPD) e Sistema Cultivo Convencional (SCC) em um Latossolo Vermelho aluminoférrico. Foi avaliado: velocidade de liberação de potássio (K), matéria seca remanescente (MSR) em bolsas de decomposição, teor de carbono orgânico... |

| In the production of greenhouse vegetables, the decline of the wholesale price of tomato and cucumber has impaired the profitability of greenhouse enterprises. New species are sought for production to improve the profitability. In Finland only one quarter of the production of sweet pepper is domestic and the proportion of organic production is small. There is a remarkable market for domestic sweet pepper. However, the shortage of nutrients and water as well as the tolerance of stress are limiting the yield of sweet pepper. In the organic greenhouse production commercial liquid fertilizers are used to insure the availability of nutrients during the formation of the yield. They are significantly more expensive than chemical fertilizers. The cost of... |

| Auch im ökologischen Anbau von Tomaten, Paprika und Auberginen werden vermehrt veredelte Pflanzen eingesetzt. Am Markt werden für jede Kulturart verschiedene Unterlagen angeboten. Am Kompetenzzentrum für den ökoloischen Gemüsebau in Bamberg (Bayr. Landesanstalt f. Wein- u. Gartenbau) wurden in 2007 hierzu umfangreiche Vergleiche durchgeführt. Es zeigte sich, dass die Wahl der Unterlage eine massive Auswirkung auf den Ertrag haben kann. Nicht alle Unterlagen sind für den Bioanbau gleich gut geeignet. Bei der Auswahl der passenden Unterlage reicht es keinesfalls die Resistenzen zu betrachten, auch andere Faktoren müssen Beachtung finden. |

| O sistema de manejo pode afetar a disponibilidade de nutrientes para as plantas, em decorrência do sistema de rotação de culturas e da quantidade de resíduo vegetal presente na superfície do solo. O objetivo deste trabalho foi avaliar a quantidade de nitrogênio (N) e fósforo (P) acumulados no tecido vegetal de aveia preta, trigo, centeio, ervilhaca, nabo e tremoço azul, além de verificar seu estado nutricional de N e P. O experimento esta instalado no Instituto Agronômico do Paraná (IAPAR) em Pato Branco, Paraná, em um Latossolo Vermelho aluminoférrico. Em maio de 2011 os tratamentos foram semeados, sendo seis plantas de cobertura: trigo, aveia preta, centeio, ervilhaca, nabo forrageiro e tremoço azul cultivados sob Sistema Plantio Direto (SPD) e Sistema... |

| Bodemkwaliteit is een containerbegrip dat biologische, chemische en fysische componenten omvat. Bodemgezondheid is een nauwer begrip dat beschreven kan worden vanuit een ecosysteem benadering. De begrippen stabiliteit en zelfregulatie, vitaliteit, ecologische veerkracht, organisatiegraad en biodiversiteit worden ten opzichte van elkaar gepositioneerd. Ziektewerendheid is een weer nauwere invulling van het begrip bodemkwaliteit en heeft uitsluitend betrekking op het vermogen van gronden om, ondanks de aanwezigheid van pathogenen, de expressie van de pathogeen in het gewas laag te houden. Negen mechanismen waarop de ziektewerendheid gebaseerd kan zijn worden beschreven. Het feitelijk vaststellen (meten) van ziektewerendheid gebeurt in biotoetsen met... |

| Soil organic matter (SOM) constitutes the largest reservoir of carbon (C) and nitrogen (N) of the earth's surface. In agricultural soils, the organic fraction is of great importance in maintaining soil quality, while contributing a small fraction. Thus, the adoption of soil management practices and cover crops are important to promote the C and N accumulation in the soil and consequently improve its quality. The no-tillage system (NT) as conservation practice improves the soil structure, water infiltration and increases the contribution of C and N in the soil by deposition of crop residue on the surface. Thus, the soil is kept constantly covered by organic residuce of plants during their vegetative stage. This study aims to evaluate the stocks of C and N... |

| Organic phosphorus (P) is an important source of phosphate for plants both in natural environments and in cultivated soils. Growing plants with high P recycling capacity may increase the importance of organic forms in phosphate availability mainly in undisturbed soils. The aim of this study was to evaluate the effect of long period of cultivation of different winter species under different soil management systems in the distribution of soil organic P forms, in the P content stored into the soil microbial biomass (SMB) and in the acid phosphatase enzyme activity. The experiment was established in 1986 with six winter treatments (blue lupine, hairy vetch, oat, radish, wheat and fallow) implanted in a Rhodic Hapludox in southern Brazil, under no-tillage... |

| O objetivo do presente trabalho foi avaliar a liberação de P a partir da decomposição dos resíduos de plantas de cobertura. Em setembro de 2011, em um experimento instalado em 1986 sobre um Latossolo Vermelho aluminoférrico, no IAPAR, Pato Branco, PR, foram coletadas amostras da parte aérea das plantas de cobertura tremoço azul, ervilhaca comum, aveia branca, nabo forrageiro, centeio e trigo, manejadas sob SPD. Mediu-se a decomposição dos resíduos das plantas e a liberação de P por meio de bolsas de decomposição de poliéster, que foram coletadas aos 0,7,14,28,56 e 112 dias após o manejo das plantas. Avaliaram-se as taxas de decomposição e o tempo de meia vida da MSPA e do P. O delineamento estatístico utilizado foi de blocos casualizados com três... |

| The research cycle encompass year-long organic vegetable greenhouse production. Spring crop was grown pickling cucumbers followed by autumn tomato. During winter month without heating annual cover crops (mixture of oat, hairy vetch and field peas) were grown and as an green manure incorporated to the soil in spring before cucumber cultivation. Additional organic fertilizers (compost and chicken manure) were applied before cucumber and tomato planting. In the period between cucumber and tomato cultivation the soil in greenhouse was solarizated. In both crops soil surface was mulched with black fleece or fresh red clover biomass. Transplants of both species were produced in organic substrate. Cucumbers were planting in the soil but tomatoes in bottomless... |
