1. COMPARAÇÃO DE MÉTODOS PARA DETERMINAÇÃO DE SUBSTÂNCIAS HÚMICAS EM FERTILIZANTES LÍQUIDOS COMERCIAIS
The beneficial effects of humic substances (HS) on crop development have been evidenced in the last decade, leading to the commercialization of HS products with fertilizing properties. Currently, three methods are frequently used for HS determination: method described in the manual of the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA); method

5. Influence of ZnO Nanoparticles and a Non-Nano ZnO on Survival and Reproduction of Earthworm and Springtail in Tropical Natural Soil
ABSTRACT: In recent years, various studies and development using nanoparticles (NPs) have been carried out in the most diverse areas of knowledge. Although nanomaterials are widely employed by many sectors and some may have a fertilizing potential, little is known about their effects on the environment. This study aimed to evaluate the effect of applying, in

6. Initial Growth of Pinus taeda by Fertilization Response at Planting
ABSTRACT The objective of this study was to evaluate how the fertilizer composition, type and application method contribute to the initial growth of Pinus taeda applied at planting. Seedlings from an open-pollinated seed orchard of Pinus taeda were planted on a Humic Dystrudepts soil containing 15 treatments of fertilizer application at planting. Basal diam

7. Planting spacing and NK fertilizing on physiological indexes and fruit production of papaya under semiarid climate
ABSTRACT The nutritional requirements of papaya (Carica papaya L.) increase continuously throughout the crop cycle, especially for potassium and nitrogen, which are the most required nutrients and act on plant vital functions such as photosynthetic activity, respiration, transpiration and stomatal regulation. An experiment was conducted from November 2010 to

8. Bioforticação agronômica com selênio em arroz / Agronomic biofortification with selenium in rice
O selênio (Se) é considerado essencial para humanos e animais por fazer parte de uma série de reações químicas e possuir propriedades antioxidantes. Dietas deficientes em Se estão associadas com problemas de saúde. Sendo assim, espera-se com a biofortificação com Se, minimizar os problemas relacionados a essas deficiências, e a escolha de culturas

11. Transferência do carbono de resíduos da colheita de eucalipto para frações da matéria orgânica do solo / Carbon transference from eucalypt harvest residues to soil organic matter fractions
Eucalypt plantation areas in Brazil have increased continuously over the years. The practice of removing more lignified material, such as bark and branches, from the ground after wood harvesting in eucalypt forests may prevent the stabilization of carbon (C) in recalcitrant fractions of soil organic matter (SOM). The recalcitrance of such organic fractions i

12. Nitrogen, phosphorus and potassium recommendation for sunflower under no-tillage system in Paraguay / RECOMENDAÇÃO DE NITROGÊNIO, FÓSFORO E POTÁSSIO PARA GIRASSOL SOB SISTEMA PLANTIO DIRETO NO PARAGUAI.
Sunflower crop has some important agronomic characteristics, as great fitomassa production, larger resistance to the drought, cold and heat than most of the cultivated species and wide adaptability to different conditions of soil and climates. Its deep root system provides absorption of nutrients of the deepest layers, ciclying great amounts of nitrogen (N),
