3. Organic Fertilizer for Production of Toona ciliata Seedlings
ABSTRACT This study evaluated the effect of different sources of organic fertilizer and their most appropriate proportions to produce Toona ciliata seedlings. Broiler litter and cattle manure were used as organic fertilizer at four proportions in the substrate (0, 15, 30, and 45%). A control treatment was adopted with 6 kg controlled-release fertilizers (m-

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. 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

7. Otimização do manejo da pinta preta causada por Guignardia citricarpa Kiely na produção ecológica de tangerinas cv. Montenegrina sob a ótica da pesquisa participativa / Optimization of management techniques of black spot (Guignardia citricarpa Kiely.) in ecological orchards of tangerine trees cv. montenegrinafrom the perspective of participatory research
In the state of Rio Grande do Sul many citric species are grown, the town of Montenegro, in Vale do Caí/RS stands out among the most important producers. For the production of fruits for in natura consumption most of the local farmers adopt technological packages that consist in the use of chemical inputs and in environmetal simplification. However, experim

8. Establishment of recommendations and parameters for use of urban waste compost in agriculture in the State of Sao Paulo - Brazil.
The organic matter present in urban waste (45 to 60% of total dry mass), after being stabilized in the form of compost, is recommended for application in agricultural soils, since it improves its physical and chemical properties and benefits the soil biological processes. Also, the urban waste compost has been economically viable for application in agricultu

9. Efeito de adubos orgânicos sobre Meloidogyne javanica em tomateiro / Effect of organic amendments on Meloidogyne javanica in tomato plant
Os nematoides das galhas causam grandes perdas em olerícolas, sendo economicamente importantes patógenos de tomate em todo o mundo. O uso de nematicidas sintéticos não é desejável por contaminarem o meio ambiente. Devido a isso, métodos alternativos de controle vêm sendo estudados para o controle de fitonematoides, como o uso de materiais orgânicos

12. Agronomic efficiency and residual effect of pand k rock biofertilizers with acidithiobacillus in two lecttuce consecutive crops in a brazilian soil from the Cariri cearense / Eficiência agronômica e poder residual de biofertilizantes de rochas com acidithiobacilus em cultivos consecutivos com alface em solo do Cariri cearense
Production of rock biofertilizers is a practical process with reduction of energy consumption and increasing nutrients availability in soils. A field experiment was carried out applying P and K biofertilizers from phosphate rock (Apatite-PR) and potash rock (biotite-KR) plus sulfur inoculated with Acidithiobacillus, on lettuce (cv. Crespa) in two consecutive
