Unbiased approach to diagnose the nutrient status of red guava (Psidium guajava)
(2012-09-30)
Fertilization of guava relies on soil and tissue testing. The interpretation of tissue test is currently conducted by comparing nutrient concentrations or dual ratios with critical values or ranges. The critical value ...
Guava Waste to Sustain Guava (Psidium guajava) Agroecosystem: Nutrient Balance Concepts
(Frontiers Media Sa, 2016-08-29)
The Brazilian guava processing industry generates 5.5 M Mg guava waste year I that could be recycled sustainably in guava agro-ecosystems as slow-release fertilizer. Our objectives were to elaborate nutrient budgets and ...
Native and alien herbaceous plants in the Brazilian Cerrado are (co-)limited by different nutrients
(2016-03-01)
Background and aims: The diverse flora of the Brazilian Cerrado is threatened by agricultural expansion, nutrient enrichment and invasion of alien plants. We performed a fertilization experiment to investigate the nature ...
Uso racional de nutrientes no cultivo hidropônico de amorperfeito
(2006-07-01)
The objective of this work was to evaluate different concentrations of nutritional solution in the hydroponic cultivation of Viola x wittrockiana Gams. The experiment was conducted in DFT hydroponic system, in a completely ...
Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2010-01)
We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ...
The plant ionome revisited by the nutrient balance concept
(Frontiers Research Foundation, 2013-03-22)
Tissue analysis is commonly used in ecology and agronomy to portray plant nutrient signatures. Nutrient concentration data, or ionomes, belong to the compositional data class, i.e., multivariate data that are proportions ...
Phosphorus Over-Fertilization and Nutrient Misbalance of Irrigated Tomato Crops in Brazil
(Frontiers Media Sa, 2017-05-19)
Over the past 20 years, the use of center-pivot irrigation has increased tomato (Solanum lycopersicum L.) yields in Brazil from 42 Mg ha(-1) to more than 80 Mg ha(-1). In the absence of field trials to support fertilizer ...
Meta-analysis in the Selection of Groups in Varieties of Citrus
(2015-08-22)
Brazil is the largest producer of oranges (Citrus sinensis) in the world. The nutrient management of tree orchards is designed from experiments with a limited number of varieties. This knowledge is transferred to other ...
Norms establishment of the Diagnosis and Recommendation Integrated System (DRIS) for nutritional diagnosis of sugarcane.
(Pesquisa Agropecuária Brasileira, Brasília, v. 38, nº 2, p.277-282, fev. 2003., 2011)
