1. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

2. Growth and nutrients content of heliconia under mineral fertilization
Resumo Heliconias têm grande importância comercial devido à durabilidade de suas inflorescências, tamanhos, formas e cores brilhantes. Em relação à sua produção, a nutrição mineral da cultura é um dos aspectos mais relevantes para a obtenção de hastes florais de qualidade. O objetivo foi determinar a influência do N-P-K no crescimento e estado

3. The combination of compost or biochar with urea and NBPT can improve nitrogen-use efficiency in maize
ABSTRACT The addition of organic residues to agricultural soils has been used as a practical alternative to improve crop quality and health. The objective of this work was to evaluate maize physiological and nutritional responses to the application of compost and biochar combined with urea (N) and N-(n-butyl) thiophosphoric triamide (NBPT). The experiment wa

4. Use of Organic Compost Containing Waste from Small Ruminants in Corn Production
ABSTRACT Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigati

5. Colonization of Greek olive cultivars' root system by arbuscular mycorrhiza fungus: root morphology, growth, and mineral nutrition of olive plants
Rooted leafy cuttings of three Greek olive (Olea europaea L.) cultivars (Koroneiki, Kothreiki and Chondrolia Chalkidikis) were grown for six months in three soil types, in an experimental greenhouse, in order to investigate: i) if their root system was colonized by arbuscular mycorrhiza fungus (AMF) genus and, ii) if genotypic differences concerning growth a

6. GESSO AGRÍCOLA E ADUBAÇÃO NITROGENADA NA CULTURA DO MILHO EM SISTEMA PLANTIO DIRETO
A considerably part of the high nitrogen (N) rates applied in corn is not absorbed due root growth restriction by subsoil acidity. Gypsum is able to improve conditions for root growth and lead to greater N uptake efficiency, increasing corn yield. Thus to evaluate the effect of gypsum and N on top dressing on soil chemical attributes, root growth , mineral n

7. The effects of arbuscular mycorrhizal fungi inoculation on Euterpe oleracea Mart. seedlings.
With the objective of verifying the response of Euterpe oleracea Mart. seedling to seven arbuscular mycorrhizal fungi species, an experimental trial was carried out under greenhouse conditions. Seeds of E. oleracea were sown in carbonized rice husk. Germinating seeds were initially transferred to plastic cups, containing fumigated Reddish Yellow Quartz Sand

8. Crecimiento inicial de Palo de Rosa (Aniba rosaeodora Ducke) en distintos ambientes de fertilidad
Studies of nutritional requirements are of great importance for identifying the most important nutrients in physiologic development and seedling growth. A greenhouse pot experiment was conducted at INPA to evaluate the mineral nutritional demands and the effects of macronutrient omission in the plant growth of Aniba rosaeodora Ducke. The following treatments

9. Absorção, eficiência de uso e partição do fósforo em plantas cítricas / Uptake, use and partitioning of phosphorous in citrus plants
The low phosphorus (P) availability is often a growth-limiting to a number of crops growing in Brazil, including citrus plants. Therefore, we expected that studies about P citrus nutrition could be useful to improve the management of these plants at low-P soils. Therefore, four experiments were carried out under greenhouse conditions. As strategy, acid phosp

10. Potencial poluidor de rejeitos carboníferos : II- efeitos da recuperação com camadas de solo sobre as plantas e a população microbiana / Pollutant potencial of coal rejects . II – Recuperation effects with soil layers in plants and microbial population
A minimização do impacto sobre o ambiente advindo da mineração do carvão pode ser obtida pela recomposição topográfica da área minerada, seguida da cobertura dos rejeitos com uma camada de solo e de práticas de revegetação. Em vista disso, desenvolveu-se o presente trabalho com o objetivo de avaliar o efeito da adição de camadas de solo com dif

11. Longevidade foliar, compostos fenolicos e nitrogenados em arvores e lianas de um fragmento de Cerrado na Estação Experimental de Itirapína, São Paulo / Leaf life span, nitrogenous and phenolic compunds in trees and lianas from a Cerrado fragment in the Itirapina experimental station in São Paulo
Trees and lianas present different strategies for allocating resources during the phonological cycle. Whereas Lianas are important floristic components and account for a significant number of rainforest species, few studies have been conducted in the Cerrado (a savanna like vegetation) biome. The duration of the leaf life span in different species reflects b

12. Nitrogênio e enxofre para gramínea forrageira: atributos do solo e aspectos metabólicos, nutricionais e produtivos da planta / Nitrogen and sulphur for graminaceous forage plants: soil attributes and metabolic, nutritional and productive aspects of plants
The nitrogen and sulphur availability in soil might influence plant growth, affecting the vegetal production. The objectives of this work were: a) to assess fertilization with nitrogen and sulphur rates on yield of Brachiaria brizantha cv. Marandu (Marandu palisadegrass) under establishment in a soil supporting degrading pasture of Brachiaria decumbens (Sign
