Conteúdo:  Abstract: Vegetative endotherapy has shown satisfactory results in replacing conventional techniques for crop production material applications, such as spraying or via soil, in trees of perennial species. This review presents an overview of concepts and classifications for existing injection methods and covers applications from articles published in the last eighteen years on endotherapeutic techniques. An Excel interactive dashboard with data segmentation and filters to facilitate understanding of the data is provided. The indicators more relevant to researchers and producers, including the tree species evaluated, which were deciduous trees (24%), conifers (11%), ornamental (11%), and fruit trees (54%), are outlined. The most used products were insecticides, fungicides, and antibiotics, which are discussed. Pressurized and nonpressurized technologies were evaluated based on trunk opening, interface, and injection methods. And finally, an approach to good practices in precision agriculture is also discussed.

Título:  Field application of the 15N isotope dilution technique for the reliable quantification of plant-associated biological nitrogen fixation.
Ano de publicação:  1995

Conteúdo:  To apply the isotope dilution (ID) technique, it is necessary to grow the "N2-fixing" crop in a soil where the mineral N is labelled with 15N. Normally the "N2-fixing" crop and a suitable non-N2-fixing control crop are grown in the same labelled soil and the 15N enrichment of the control crop is assumed to be equal to the 15N enrichment of the nitrogen (N) derived from the soil in the "N2-fixing" crop. In this case the proportion of unlabelled N being derived from the air via biological N2 fixation (BNF) in the "N2-fixing" crop will be proportional to the dilution of the enrichment of the N derived from the labelled soil. To label the soil, the technique most often used is to add a single addition of 15N-labelled N fertilizer shortly before, at, or shortly after, the planting of the crops. Data in the literature clearly show that this technique results in a rapid fall in the 15N enrichment of soil mineral N with time. Under these conditions, if the control and the "N2-fixing" crops have different patterns of N uptake from the soil they will inevitably obtain different 15N enrichments in the soil-derived N. In this case the isotope dilution technique cannot be applied, or if it is, there will be an error introduced into, the estimate of the contribution of N derived from BNF. Several experiments are described which explore different strategies of application of the ID technique to attempt to attenuate the errors involved. The results suggest that it is wise to use slow-releas... Mostrar Tudo
