Early methods of tissue diagnosis opposed the concept of critical nutrient concentrations supported by the laws of the minimum and the optimum to the more complex one of nutrient balances. But this proved to be a futile ...

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 ...

Soil analysis is used to estimate nutrient availability, but nutrient concentrations are not always related to yield in most fruit plants, including grapevines. Thus, additional multivariate mathematical models, such as ...

The nutritional status of fruit trees can be routinely evaluated either indirectly, via soil chemical analysis, or directly, via plant leaf analysis. The usefulness of leaf diagnosis depends on leaf sampling, chemical ...

O manejo eficiente de nutrientes é crucial para atingir alta produtividade de frutos. Resultados da análise do tecido são comumente interpretados usando faixas críticas de concentração de nutrientes (CNCR) e Sistema Integrado ...

Plant ionomes and soil nutrients are commonly diagnosed in agronomy using concentration and nutrient ratio ranges. However, both diagnoses are biased by redundancy of information, subcompositional incoherence and non-normal ...

Citrus plants adapt well in tropical, temperate, and subtropical countries, which turns them of great importance to the agriculture sector. Usually, kinetics parameters related to nutrient uptake are not evaluated, that ...
